abstract: AIM Reduction of elevated blood pressure ( BP ) has been an important treatment goal in elderly hypertensive patients . However , it has been reported that an excessive reduction of systolic BP to less than 120mmHg might be harmful in such patients . We investigated whether this was the case in a study which assessed long-term antihypertensive efficacy , tolerability and impact on cardiovascular/cerebrovascular ( CV ) morbidity/mortality in a large cohort of Japanese patients . METHODS This study was performed at general practitioners ' offices nationwide with a target sample size of 1500 patients . Hypertensive patients aged 60years or more who achieved successful BP control with c and esartan monotherapy , and who tolerated the treatment for at least 8weeks , were enrolled into the study and followed for 3years . RESULTS BP was maintained below the target level of 140/90mmHg over the 3-year period . The incidence of CV events during the study period was 20.4/1000person-years . Investigation of the relationship between BP and the incidence of CV events revealed that patients with higher BP generally had a higher incidence of events . However , very elderly patients ( ≥75years ) with a systolic BP ( SBP ) of less than 120mmHg also had a higher incidence of CV events compared with those with an SBP of 120 - 139mmHg . CONCLUSION This study demonstrated that treatment with c and esartan maintained long-term control of BP in elderly hypertensive patients without serious adverse events . CV events demonstrated a J-curve relationship with SBP in patients aged 75years or older , which suggests that excessive BP reductions might be harmful for very elderly patients Summary Background The associations of blood pressure with the different manifestations of incident cardiovascular disease in a contemporary population have not been compared . In this study , we aim ed to analyse the associations of blood pressure with 12 different presentations of cardiovascular disease . Methods We used  linked electronic health records from 1997 to 2010 in the CALIBER ( CArdiovascular research using LInked Bespoke studies and Electronic health Records ) programme to assemble a cohort of 1·25 million patients , 30 years of age or older and initially free from cardiovascular disease , a fifth of whom received blood pressure-lowering treatments . We studied the heterogeneity in the age-specific associations of clinical ly measured blood pressure with 12 acute and chronic cardiovascular diseases , and estimated the lifetime risks ( up to 95 years of age ) and cardiovascular disease-free life-years lost adjusted for other risk factors at index ages 30 , 60 , and 80 years . This study is registered at Clinical Trials.gov , number NCT01164371 . Findings During 5·2 years median follow-up , we recorded 83 098 initial cardiovascular disease presentations . In each age group , the lowest risk for cardiovascular disease was in people with systolic blood pressure of 90–114 mm Hg and diastolic blood pressure of 60–74 mm Hg , with no evidence of a J-shaped increased risk at lower blood pressures . The effect of high blood pressure varied by cardiovascular disease endpoint , from strongly positive to no effect . Associations with high systolic blood pressure were strongest for intracerebral haemorrhage ( hazard ratio 1·44 [ 95 % CI 1·32–1·58 ] ) , subarachnoid haemorrhage ( 1·43 [ 1·25–1·63 ] ) , and stable angina ( 1·41 [ 1·36–1·46 ] ) , and weakest for abdominal aortic aneurysm ( 1·08 [ 1·00–1·17 ] ) . Compared with diastolic blood pressure , raised systolic blood pressure had a greater effect on angina , myocardial infa rct ion , and peripheral arterial disease , whereas raised diastolic blood pressure had a greater effect on abdominal aortic aneurysm than did raised systolic pressure . Pulse pressure associations were inverse for abdominal aortic aneurysm ( HR per 10 mm Hg 0·91 [ 95 % CI 0·86–0·98 ] ) and strongest for peripheral arterial disease ( 1·23 [ 1·20–1·27 ] ) . People with  hypertension ( blood pressure ≥140/90 mm Hg or those receiving blood pressure-lowering drugs ) had a lifetime risk of overall cardiovascular disease at 30 years of age of 63·3 % ( 95 % CI 62·9–63·8 ) compared with 46·1 % ( 45·5–46·8 ) for those with normal blood pressure , and developed cardiovascular disease 5·0 years earlier ( 95 % CI 4·8–5·2 ) . Stable and unstable angina accounted for most ( 43 % ) of the cardiovascular disease-free years of life lost associated with hypertension from index age 30 years , whereas heart failure and stable angina accounted for the largest proportion ( 19 % each ) of years of life lost from index age 80 years . Interpretation The widely held assumptions that blood pressure has strong associations with the occurrence of all cardiovascular diseases across a wide age range , and that diastolic and systolic associations are concordant , are not supported by the findings of this high-resolution study . Despite modern treatments , the lifetime burden of hypertension is substantial . These findings emphasise the need for new  blood pressure-lowering strategies , and will help to inform the design of r and omised trials to assess them . Funding Medical Research Council , National Institute for Health Research , and Wellcome Trust Hypertension guidelines recommend blood pressure self-measurement at home ( HBP ) , but no previous trial has assessed cardiovascular outcomes in hypertensive patients treated according to HBP . The multicenter Hypertension Objective Treatment Based on Measurement by Electrical Devices of Blood Pressure ( HOMED-BP ; 2001–2010 ) trial involved 3518 patients ( 50 % women ; mean age 59.6 years ) with an untreated systolic/diastolic HBP of 135–179/85–119 mm Hg . In a 2 × 3 design , patients were r and omized to usual control ( 125–134/80–84 mm Hg ( UC ) ) vs. tight control ( < 125/<80 mm Hg ( TC ) ) of HBP and to initiation of drug treatment with angiotensin converting enzyme inhibitors , angiotensin receptor blockers or calcium channel blockers . During follow-up , a computer algorithm automatically generated treatment recommendations based on HBP . At the last follow-up ( median 5.3 years ) , TC patients used more antihypertensive drugs than UC patients ( 1.82 vs. 1.74 defined daily doses , P=0.045 ) and had a greater HBP reduction ( 21.3/13.1 mm Hg vs. 22.7/13.9 mm Hg , P=0.018/0.020 ) , but they less frequently achieved the lower HBP targets ( 37.4 vs. 63.5 % , P<0.0001 ) . The primary end point , cardiovascular death plus stroke and myocardial infa rct ion , occurred in 25 UC and 26 TC patients ( hazard ratio , 1.02 ; 95 % confidence interval , 0.59–1.77 ; P=0.94 ) . Rates were similar ( P⩾0.13 ) in the three drug groups . In all patients combined , the risk of the primary end point independently increased by 41 % ( 6–89 % ; P=0.019 ) and 47 % ( 15–87 % ; P=0.0020 ) for a 1-s.d . increase in baseline ( 12.5 mm Hg ) and follow-up ( 13.2 mm Hg ) systolic HBP . The 5-year risk was minimal ( ⩽1 % ) if on-treatment systolic HBP was 131.6 mm Hg or less . HOMED-BP proved the feasibility of adjusting antihypertensive drug treatment based on HBP and suggests that a systolic HBP level of 130 mm Hg should be an achievable and safe target BACKGROUND The most appropriate targets for systolic blood pressure to reduce cardiovascular morbidity and mortality among persons without diabetes remain uncertain . METHODS We r and omly assigned 9361 persons with a systolic blood pressure of 130 mm Hg or higher and an increased cardiovascular risk , but without diabetes , to a systolic blood-pressure target of less than 120 mm Hg ( intensive treatment ) or a target of less than 140 mm Hg ( st and ard treatment ) . The primary composite outcome was myocardial infa rct ion , other acute coronary syndromes , stroke , heart failure , or death from cardiovascular causes . RESULTS At 1 year , the mean systolic blood pressure was 121.4 mm Hg in the intensive-treatment group and 136.2 mm Hg in the st and ard-treatment group . The intervention was stopped early after a median follow-up of 3.26 years owing to a significantly lower rate of the primary composite outcome in the intensive-treatment group than in the st and ard-treatment group ( 1.65 % per year vs. 2.19 % per year ; hazard ratio with intensive treatment , 0.75 ; 95 % confidence interval [ CI ] , 0.64 to 0.89 ; P<0.001 ) . All-cause mortality was also significantly lower in the intensive-treatment group ( hazard ratio , 0.73 ; 95 % CI , 0.60 to 0.90 ; P=0.003 ) . Rates of serious adverse events of hypotension , syncope , electrolyte abnormalities , and acute kidney injury or failure , but not of injurious falls , were higher in the intensive-treatment group than in the st and ard-treatment group . CONCLUSIONS Among patients at high risk for cardiovascular events but without diabetes , targeting a systolic blood pressure of less than 120 mm Hg , as compared with less than 140 mm Hg , result ed in lower rates of fatal and nonfatal major cardiovascular events and death from any cause , although significantly higher rates of some adverse events were observed in the intensive-treatment group . ( Funded by the National Institutes of Health ; Clinical Trials.gov number , NCT01206062 . ) BACKGROUND It is unknown whether either the angiotensin-II-receptor blocker irbesartan or the calcium-channel blocker amlodipine slows the progression of nephropathy in patients with type 2 diabetes independently of its capacity to lower the systemic blood pressure . METHODS We r and omly assigned 1715 hypertensive patients with nephropathy due to type 2 diabetes to treatment with irbesartan ( 300 mg daily ) , amlodipine ( 10 mg daily ) , or  placebo .  The target blood pressure was 135/85 mm Hg or less in all groups . We compared the groups with regard to the time to the primary composite end point of a doubling of the base-line serum creatinine concentration , the development of end-stage renal disease , or death from any cause . We also compared them with regard to the time to a secondary , cardiovascular composite end point . RESULTS The mean duration of follow-up was 2.6 years . Treatment with irbesartan was associated with a risk of the primary composite end point that was 20 percent lower than that in the placebo group ( P=0.02 ) and 23 percent lower than that in the amlodipine group ( P=0.006 ) . The risk of a doubling of the serum creatinine concentration was 33 percent lower in the irbesartan group than in the placebo group ( P=0.003 ) and 37 percent lower in the irbesartan group than in the amlodipine group ( P<0.001 ) . Treatment with irbesartan was associated with a relative risk of end-stage renal disease that was 23 percent lower than that in both other groups ( P=0.07 for both comparisons ) . These differences were not explained by differences in the blood pressures that were achieved . The serum creatinine concentration increased 24 percent more slowly in the irbesartan group than in the placebo group ( P=0.008 ) and 21 percent more slowly than in the amlodipine group ( P=0.02 ) . There were no significant differences in the rates of death from any cause or in the cardiovascular composite end point . CONCLUSIONS The angiotensin-II-receptor blocker irbesartan is effective in protecting against the progression of nephropathy due to type 2 diabetes . This protection is independent of the reduction in blood pressure it causes BACKGROUND Angiotensin-converting-enzyme ( ACE ) inhibitors have been used for more than a decade to treat high blood pressure  , despite the lack of data from r and omised intervention trials to show that such treatment affects cardiovascular morbidity and mortality . The Captopril Prevention Project ( CAPPP ) is a r and omised intervention trial to compare the effects of ACE inhibition and conventional therapy on cardiovascular morbidity and mortality in patients with hypertension . METHODS CAPPP was a prospect i ve , r and omised , open trial with blinded endpoint evaluation . 10,985 patients were enrolled at 536 health centres in Sweden and Finl and . Patients aged 25 - 66 years with a measured diastolic blood pressure of 100 mm Hg or more on two occasions were r and omly assigned captopril or conventional antihypertensive treatment ( diuretics , beta-blockers ) . Analysis was by intention-to-treat . The primary endpoint was a composite of fatal and non-fatal myocardial infa rct ion , stroke , and other cardiovascular deaths . FINDINGS Of 5492 patients assigned captopril and 5493 assigned conventional therapy , 14 and 13 , respectively , were lost to follow-up . Primary endpoint events occurred in 363 patients in the captopril group ( 11.1 per 1000 patient-years ) and 335 in the conventional-treatment group ( 10.2 per 1000 patient-years ; relative risk 1.05 [ 95 % CI 0.90 - 1.22 ] , p=0 - 52 ) . Cardiovascular mortality was lower with captopril than with conventional treatment ( 76 vs 95 events ; relative risk 0.77 [ 0.57 - 1 - 04 ] , p=0.092 ) , the rate of fatal and non-fatal myocardial infa rct ion was similar ( 162 vs 161 ) , but fatal and non-fatal stroke was more common with captopril ( 189 vs 148 ; 1.25 [ 1 - 01 - 1 - 55 ] . p=0.044 ) . INTERPRETATION Captopril and conventional treatment did not differ in efficacy in preventing cardiovascular morbidity and mortality . The difference in stroke risk is probably due to the lower levels of blood pressure obtained initially in previously treated patients r and omised to conventional therapy BACKGROUND Whether the treatment of patients with hypertension who are 80 years of age or older is beneficial is unclear . It has been suggested that antihypertensive therapy may reduce the risk of stroke , despite possibly increasing the risk of death . METHODS We r and omly assigned 3845 patients from Europe , China , Australasia , and Tunisia who were 80 years of age or older and had a sustained systolic blood pressure of 160 mm Hg or more to receive either the diuretic indapamide ( sustained release , 1.5 mg ) or matching placebo .  The angiotensin-converting-enzyme inhibitor perindopril ( 2 or 4 mg ) , or matching placebo , was added if necessary to achieve the target blood pressure of 150/80 mm Hg . The primary end point was fatal or nonfatal stroke . RESULTS The active-treatment group ( 1933 patients ) and the placebo group ( 1912 patients ) were well matched ( mean age , 83.6 years ; mean blood pressure while sitting , 173.0/90.8 mm Hg ) ; 11.8 % had a history of cardiovascular disease . Median follow-up was 1.8 years . At 2 years , the mean blood pressure while sitting was 15.0/6.1 mm Hg lower in the active-treatment group than in the placebo group . In an intention-to-treat analysis , active treatment was associated with a 30 % reduction in the rate of fatal or nonfatal stroke ( 95 % confidence interval [ CI ] , -1 to 51 ; P=0.06 ) , a 39 % reduction in the rate of death from stroke ( 95 % CI , 1 to 62 ; P=0.05 ) , a 21 % reduction in the rate of death from any cause ( 95 % CI , 4 to 35 ; P=0.02 ) , a 23 % reduction in the rate of death from cardiovascular causes ( 95 % CI , -1 to 40 ; P=0.06 ) , and a 64 % reduction in the rate of heart failure ( 95 % CI , 42 to 78 ; P<0.001 ) . Fewer serious adverse events were reported in the active-treatment group ( 358 , vs. 448 in the placebo group ; P=0.001 ) . CONCLUSIONS The results provide evidence that antihypertensive treatment with indapamide ( sustained release ) , with or without perindopril , in persons 80 years of age or older is beneficial . ( Clinical Trials.gov number , NCT00122811 [ Clinical Trials.gov ] . ) CONTEXT Hypertension is a leading cause of end-stage renal disease ( ESRD ) in the United States , with no known treatment to prevent progressive declines leading to ESRD . OBJECTIVE To compare the effects of 2 levels of blood pressure ( BP ) control and 3 antihypertensive drug classes on glomerular filtration rate ( GFR ) decline in hypertension . DESIGN R and omized 3 x 2 factorial trial with enrollment from February 1995 to September 1998 . SETTING AND PARTICIPANTS A total of 1094 African Americans aged 18 to 70 years with hypertensive renal disease ( GFR , 20 - 65 mL/min per 1.73 m(2 ) ) were recruited from 21 clinical centers throughout the United States and followed up for 3 to 6.4 years . INTERVENTIONS Participants were r and omly assigned to 1 of 2 mean arterial pressure goals , 102 to 107 mm Hg ( usual ; n = 554 ) or 92 mm Hg or less ( lower ; n = 540 ) , and to initial treatment with either a beta-blocker ( metoprolol 50 - 200 mg/d ; n = 441 ) , an angiotensin-converting enzyme inhibitor ( ramipril 2.5 - 10 mg/d ; n = 436 ) or a dihydropyridine calcium channel blocker , ( amlodipine 5 - 10 mg/d ; n = 217 ) . Open-label agents were added to achieve the assigned BP goals . MAIN OUTCOME MEASURES Rate of change in GFR ( GFR slope ) ; clinical composite outcome of reduction in GFR by 50 % or more ( or > or = 25 mL/min per 1.73 m2 ) from baseline , ESRD , or death . Three primary treatment comparisons were specified : lower vs usual BP goal ; ramipril vs metoprolol ; and amlodipine vs metoprolol . RESULTS Achieved BP averaged ( SD ) 128/78 ( 12/8 ) mm Hg in the lower BP group and 141/85 ( 12/7 ) mm Hg in the usual BP group . The mean ( SE ) GFR slope from baseline through 4 years did not differ significantly between the lower BP group ( -2.21 [ 0.17 ] mL/min per 1.73 m2 per year ) and the usual BP group ( -1.95 [ 0.17 ] mL/min per 1.73 m2 per year ; P = .24 ) , and the lower BP goal did not significantly reduce the rate of the clinical composite outcome ( risk reduction for lower BP group = 2 % ; 95 % confidence interval [ CI ] , -22 % to 21 % ; P = .85 ) . None of the drug group comparisons showed consistent significant differences in the GFR slope . However , compared with the metoprolol and amlodipine groups , the ramipril group manifested risk reductions in the clinical composite outcome of 22 % ( 95 % CI , 1%-38 % ; P = .04 ) and 38 % ( 95 % CI , 14%-56 % ; P = .004 ) , respectively . There was no significant difference in the clinical composite outcome between the amlodipine and metoprolol groups . CONCLUSIONS No additional benefit of slowing progression of hypertensive nephrosclerosis was observed with the lower BP goal . Angiotensin-converting enzyme inhibitors appear to be more effective than beta-blockers or dihydropyridine calcium channel blockers in slowing GFR decline BACKGROUND This study was undertaken to determine whether use of the direct renin inhibitor aliskiren would reduce cardiovascular and renal events in patients with type 2 diabetes and chronic kidney disease , cardiovascular disease , or both . METHODS In a double-blind fashion , we r and omly assigned 8561 patients to aliskiren ( 300 mg daily ) or placebo as an adjunct to an angiotensin-converting-enzyme inhibitor or an angiotensin-receptor blocker . The primary end point was a composite of the time to cardiovascular death or a first occurrence of cardiac arrest with resuscitation ; nonfatal myocardial infa rct ion ; nonfatal stroke ; unplanned hospitalization for heart failure ; end-stage renal disease , death attributable to kidney failure , or the need for renal-replacement therapy with no dialysis  or transplantation available or initiated ; or doubling of the baseline serum creatinine level . RESULTS The trial was stopped prematurely after the second interim efficacy analysis . After a median follow-up of 32.9 months , the primary end point had occurred in 783 patients ( 18.3 % ) assigned to aliskiren as compared with 732 ( 17.1 % ) assigned to placebo ( hazard ratio , 1.08 ; 95 % confidence interval [ CI ] , 0.98 to 1.20 ; P=0.12 ) . Effects on secondary renal end points were similar . Systolic and diastolic blood pressures were lower with aliskiren ( between-group differences , 1.3 and 0.6 mm Hg , respectively ) and the mean reduction in the urinary albumin-to-creatinine ratio was greater ( between-group difference , 14 percentage points ; 95 % CI , 11 to 17 ) . The proportion of patients with hyperkalemia ( serum potassium level , ≥6 mmol per liter ) was significantly higher in the aliskiren group than in the placebo group ( 11.2 % vs. 7.2 % ) , as was the proportion with reported hypotension ( 12.1 % vs. 8.3 % ) ( P<0.001 for both comparisons ) . CONCLUSIONS The addition of aliskiren to st and ard therapy with renin-angiotensin system blockade in patients with type 2 diabetes who are at high risk for cardiovascular and renal events is not supported by these data and may even be harmful . ( Funded by Novartis ; ALTITUDE Clinical Trials.gov number , NCT00549757 . ) Abstract Objective : To determine whether tight control of blood pressure prevents macrovascular and microvascular complications in patients with type 2 diabetes . Design : R and omised controlled trial comparing tight control of blood pressure aim ing at a blood pressure of < 150/85 mm Hg ( with the use of an angiotensin converting enzyme inhibitor captopril or a β blocker atenolol as main treatment ) with less tight control aim ing at a blood pressure of < 180/105 mm Hg . Setting : 20 hospital based clinics in Engl and , Scotl and , and Northern Irel and . Subjects : 1148 hypertensive patients with type 2 diabetes ( mean age 56 , mean blood pressure at entry 160/94 mm Hg ) ; 758 patients were allocated to tight control of blood pressure  and 390 patients to less tight control  with a median follow up of 8.4 years . Main outcome measures : Predefined clinical end points , fatal and non-fatal , related to diabetes , deaths related to diabetes , and all cause mortality . Surrogate measures of microvascular disease included urinary albumin excretion and retinal photography . Results : Mean blood pressure during follow up was significantly reduced in the group assigned tight blood pressure control ( 144/82 mm Hg ) compared with the group assigned to less tight control ( 154/87 mm Hg ) ( P<0.0001 ) . Reductions in risk in the group assigned to tight control compared with that assigned to less tight control were 24 % in diabetes related end points ( 95 % confidence interval 8 % to 38 % ) ( P=0.0046 ) , 32 % in deaths related to diabetes ( 6 % to 51 % ) ( P=0.019 ) , 44 % in strokes ( 11 % to 65 % ) ( P=0.013 ) , and 37 % in microvascular end points ( 11 % to 56 % ) ( P=0.0092 ) , predominantly owing to a reduced risk of retinal photocoagulation . There was a non-significant reduction in all cause mortality . After nine years of follow up the group assigned to tight blood pressure control also had a 34 % reduction in risk in the proportion of patients with deterioration of retinopathy by two steps ( 99 % confidence interval 11 % to 50 % ) ( P=0.0004 ) and a 47 % reduced risk ( 7 % to 70 % ) ( P=0.004 ) of deterioration in visual acuity by three lines of the early treatment of diabetic retinopathy study ( ETDRS ) chart . After nine years of follow up 29 % of patients in the group assigned to tight control required three or more treatments to lower blood pressure to achieve target blood pressures . Conclusion : Tight blood pressure control in patients with hypertension and type 2 diabetes achieves a clinical ly important reduction in the risk of deaths related to diabetes , complications related to diabetes , progression of diabetic retinopathy , and deterioration in visual acuity BACKGROUND Angiotensin-converting-enzyme inhibitors improve the outcome among patients with left ventricular dysfunction , whether or not they have heart failure . We assessed the role of an angiotensin-converting-enzyme inhibitor , ramipril , in patients who were at high risk for cardiovascular events but who did not have left ventricular dysfunction or heart failure . METHODS A total of 9297 high-risk patients ( 55 years of age or older ) who had evidence of vascular disease or diabetes plus one other cardiovascular risk factor and who were not known to have a low ejection fraction or heart failure were r and omly assigned to receive ramipril ( 10 mg once per day orally ) or matching placebo for a mean of five years . The primary outcome was a composite of myocardial infa rct ion , stroke , or death from cardiovascular causes . The trial was a two-by-two factorial study evaluating both ramipril and vitamin E. The effects of vitamin E are reported in a companion paper . RESULTS A total of 651 patients who were assigned to receive  ramipril ( 14.0 percent ) reached the primary end point , as compared with 826 patients who were assigned to receive placebo ( 17.8 percent ) ( relative risk , 0.78 ; 95 percent confidence interval , 0.70 to 0.86 ; P<0.001 ) . Treatment with ramipril reduced the rates of death from cardiovascular causes ( 6.1 percent , as compared with 8.1 percent in the placebo group ; relative risk , 0.74 ; P<0.001 ) , myocardial infa rct ion ( 9.9 percent vs. 12.3 percent ; relative risk , 0.80 ; P<0.001 ) , stroke ( 3.4 percent vs. 4.9 percent ; relative risk , 0.68 ; P<0.001 ) , death from any cause ( 10.4 percent vs. 12.2 percent ; relative risk , 0.84 ; P=0.005 ) , revascularization procedures ( 16.3 percent vs. 18.8 percent ; relative risk , 0.85 ; P<0.001 ) , cardiac arrest ( 0.8 percent vs. 1.3 percent ; relative risk , 0.62 ; P=0.02 ) , [ corrected ] heart failure ( 9.1 percent vs. 11.6 percent ; relative risk , 0.77 ; P<0.001 ) , and complications related to diabetes ( 6.4 percent vs. 7.6 percent ; relative risk , 0.84 ; P=0.03 ) . CONCLUSIONS Ramipril significantly reduces the rates of death , myocardial infa rct ion , and stroke in a broad range of high-risk patients who are not known to have a low ejection fraction or heart failure Recent reports suggest a possible link between nifedipine ( but not diltiazem ) and an increased risk of cancer in patients being treated with calcium antagonists BACKGROUND It has recently been reported that the use of calcium-channel blockers for hypertension may be associated with an increased risk of cardiovascular complications . Because this issue remains controversial , we studied the incidence of such complications in patients with non-insulin-dependent diabetes mellitus and hypertension who were r and omly assigned to treatment with either the calcium-channel blocker nisoldipine or the angiotensin-converting-enzyme inhibitor enalapril as part of a larger study . METHODS The Appropriate Blood Pressure Control in Diabetes ( ABCD ) Trial is a prospect i ve , r and omized , blinded trial comparing the effects of moderate control of blood pressure ( target diastolic pressure , 80 to 89 mm Hg ) with those of intensive control of blood pressure ( diastolic pressure , 75 mm Hg ) on the incidence and progression of complications of diabetes . The study also compared nisoldipine with enalapril as a first-line antihypertensive agent in terms of the prevention and progression of complications of diabetes . In the current study , we analyzed data on a secondary end point ( the incidence of myocardial infa rct ion ) in the subgroup of patients in the ABCD Trial who had hypertension . RESULTS Analysis of the 470 patients in the trial who had hypertension ( base-line diastolic blood pressure , > or = 90 mm Hg ) showed similar control of blood pressure , blood glucose and lipid concentrations , and smoking behavior in the nisoldipine group ( 237 patients ) and the enalapril group ( 233 patients ) throughout five years of follow-up . Using a multiple logistic-regression model with adjustment for cardiac risk factors , we found that nisoldipine was associated with a higher incidence of fatal and nonfatal myocardial infa rct ions ( a total of 24 ) than enalapril ( total , 4 ) ( risk ratio , 9.5 ; 95 percent confidence interval , 2.7 to 33.8 ) . CONCLUSIONS In this population of patients with diabetes and hypertension , we found a significantly higher incidence of fatal and nonfatal myocardial infa rct ion among those assigned to therapy with the calcium-channel blocker nisoldipine than among those assigned to receive enalapril . Since our findings are based on a secondary end point , they will require confirmation BACKGROUND Despite treatment , there is often a higher incidence of cardiovascular complications in patients with hypertension than in normotensive individuals . Inadequate reduction of their blood pressure is a likely cause , but the optimum target blood pressure is not known . The impact of acetylsalicylic acid ( aspirin ) has never been investigated in patients with hypertension . We aim ed to assess the optimum target diastolic blood pressure and the potential benefit of a low dose of acetylsalicylic acid in the treatment of hypertension . METHODS 18790 patients , from 26 countries , aged 50 - 80 years ( mean 61.5 years ) with hypertension and diastolic blood pressure between 100 mm Hg and 115 mm Hg ( mean 105 mm Hg ) were r and omly assigned a target diastolic blood pressure . 6264 patients were allocated to the target pressure < or = 90 mm Hg , 6264 to < or = 85 mm Hg , and 6262 to < or = 80 mm Hg . Felodipine was given as baseline therapy with the addition of other agents , according to a five-step regimen . In addition , 9399 patients were r and omly assigned 75 mg/day acetylsalicylic acid ( Bamycor , Astra ) and 9391 patients were assigned  placebo . FINDINGS Diastolic blood pressure was reduced by 20.3 mm Hg , 22.3 mm Hg , and 24.3 mm Hg , in the < or = 90 mm Hg , < or = 85 mm Hg , and < or = 80 mm Hg target groups , respectively . The lowest incidence of major cardiovascular events occurred at a mean achieved diastolic blood pressure of 82.6 mm Hg ; the lowest risk of cardiovascular mortality occurred at 86.5 mm Hg . Further reduction below these blood pressures was safe .  In patients with diabetes mellitus there was a 51 % reduction in major cardiovascular events in target group < or = 80 mm Hg compared with target group < or = 90 mm Hg ( p for trend=0.005 ) . Acetylsalicylic acid reduced major cardiovascular events by 15 % ( p=0.03 ) and all myocardial infa rct ion by 36 % ( p=0.002 ) , with no effect on stroke . There were seven fatal bleeds in the acetylsalicylic acid group and eight in the placebo group , and 129 versus 70 non-fatal major bleeds in the two groups , respectively ( p<0.001 ) . INTERPRETATION Intensive lowering of blood pressure in patients with hypertension was associated with a low rate of cardiovascular events . The HOT Study shows the benefits of lowering the diastolic blood pressure down to 82.6 mm Hg . Acetylsalicylic acid significantly reduced major cardiovascular events with the greatest benefit seen in all myocardial infa rct ion . There was no effect on the incidence of stroke or fatal bleeds , but non-fatal major bleeds were twice as common BACKGROUND In 1988 , the Systolic Hypertension in China ( Syst-China ) Collaborative Group initiated the placebo-controlled Syst-China trial to investigate whether antihypertensive drug treatment could reduce the incidence of fatal and nonfatal stroke in older Chinese patients with isolated systolic hypertension . OBJECTIVES To explore ( 1 ) whether the benefits of active treatment were evenly distributed across 4 strata , prospect ively defined according to sex and previous cardiovascular complications , and ( 2 ) whether the morbidity and mortality results were influenced by age , level of systolic or diastolic blood pressure ( BP ) , smoking or drinking habits , or diabetes mellitus at enrollment . METHODS Eligible patients had to be 60 years or older with a sitting systolic BP of 160 to 219 mm Hg and diastolic BP less than 95 mm Hg . After stratification for center , sex , and previous cardiovascular complications , 1253 patients were assigned to active treatment starting with nitrendipine ( 10 - 40 mg/d ) , with the possible addition of captopril ( 12.5 - 50.0 mg/d ) , and /or hydrochlorothiazide ( 12.5 - 50 mg/d ) . In the 1141 control patients , matching placebos were used similarly . RESULTS Male sex , previous cardiovascular complications , older age , higher systolic BP or lower diastolic BP , living in northern China , smoking , and diabetes mellitus significantly and independently increased the risk of 1 or more of the following end points : total or cardiovascular mortality , all fatal and nonfatal cardiovascular end points , all strokes , and all cardiac end points . In the placebo-control group diabetes raised the risk of all end points 2- to 3-fold ( P < or = .05 ) . However , active treatment reduced the excess risk associated with diabetes to a nonsignificant level ( P values ranging from .12-.86 ) except for cardiovascular mortality ( P = .04 ) . Cox regression with adjustments applied for significant covariates suggested that active treatment may reduce total mortality more ( P = .06 ) in women and stroke more ( P = .07 ) in men and that it may provide better protection against cardiac end points in nonsmokers than smokers ( P = .04 ) . Otherwise , the benefits of active treatment were equally manifest , regardless of the enrollment characteristics of the patients , and regardless of whether active treatment consisted of only nitrendipine or of nitrendipine associated with other active drugs . CONCLUSIONS In elderly Chinese patients with isolated systolic hypertension , stepwise antihypertensive drug treatment , starting with the dihydropyridine calcium channel blocker nitrendipine , improved prognosis . The benefit was particularly evident in diabetic patients ; for cardiac end points it tended to be larger in nonsmokers . Otherwise , the benefit of active treatment was not significantly influenced by the characteristics of the patients at enrollment in the trial OBJECTIVES We sought to evaluate the influence of pretreatment systolic blood pressure ( SBP ) on the efficacy and safety of carvedilol in patients with chronic heart failure ( CHF ) . BACKGROUND Although beta-blockers reduce the risk of death in CHF , there is little reported experience with these drugs in patients with a low pretreatment SBP , who may respond poorly to beta-blockade . METHODS We studied 2,289 patients with severe CHF who participated in the Carvedilol Prospect i ve R and omized Cumulative Survival ( COPERNICUS ) trial . RESULTS Compared with placebo , carvedilol improved the clinical status and reduced the risk of death and the combined risk of death or hospitalization for any reason , for a cardiovascular reason , or for worsening heart failure ( p < 0.001 for all ) . The relative magnitude of these benefits did not vary as a function of the pretreatment SBP ( all interaction : p > 0.10 ) . However , because patients with the lowest SBP were at highest risk of an event , they experienced the greatest absolute benefit from treatment with carvedilol . The lower the pretreatment SBP , the more likely that patients would report an adverse event , be intolerant of high doses of the study drug , or require permanent withdrawal of treatment ( p < 0.001 for all ) . However , these risks were primarily related to the severity of the underlying illness and not to treatment with carvedilol . CONCLUSIONS The current study provides little support for concerns about using beta-blockers ( particularly those with vasodilatory actions ) in patients with severe CHF who have a low SBP . Pretreatment blood pressure can identify patients who have the greatest need for risk reduction with carvedilol The incidence of ESRD is increasing dramatically . Progression to end-stage may be halted or slowed when kidney damage is detected at an early stage . Kidney damage is frequently asymptomatic but is indicated by the presence of proteinuria , hematuria , or reduced GFR . Population -based studies relating to the prevalence of kidney damage in the community are limited , particularly outside of the United States . Therefore , the prevalence of proteinuria , hematuria , and reduced GFR in the Australian adult population was determined using a cross-sectional study of 11,247 noninstitutionalized Australians aged 25 yr or over , r and omly selected using a stratified , cluster method . Subjects were interviewed and tested for  proteinuria-spot urine protein  to  creatinine ratio  ( abnormal : > /=0.20 mg/mg ) ; hematuria-spot urine dipstick ( abnormal : 1 + or greater ) confirmed by urine microscopy ( abnormal : > 10,000 red blood cells per milliliter ) or dipstick ( abnormal : 1 + or greater ) on midstream urine sample ; and reduced GFR-Cockcroft-Gault estimated GFR ( abnormal : < 60 ml/min per 1.73 m(2 ) ) . The associations between age , gender , diabetes mellitus , and hypertension , and indicators of kidney damage were examined . Proteinuria was detected in 2.4 % of cases ( 95 % CI : 1.6 % , 3.1 % ) , hematuria in 4.6 % ( 95 % CI : 3.8 % , 5.4 % ) , and reduced GFR in 11.2 % ( 95 % CI : 8.6 % , 13.8 % ) . Approximately 16 % had at least one indicator of kidney damage . Age , diabetes mellitus , and hypertension were independently associated with proteinuria ; age , gender , and hypertension with hematuria ; and age , gender , and hypertension with reduced GFR . Approximately 16 % of the Australian adult population has either proteinuria , hematuria , and /or reduced GFR , indicating the presence of kidney damage . Identifying and targeting this section of the population may provide a means to reduce the burden of ESRD The 2014 Evidence -Based Guideline for the Management of  High Blood Pressure In Adults : Report From the Panel Members Appointed to the Eighth Joint National Committee ( JNC 8) recommends several major changes from the JNC 7 report ( 1 , 2 ) . The 2014 guideline is based on a systematic review of r and omized , controlled trials ( RCTs ) by a multidisciplinary panel using a process informed by Institute of Medicine recommendations for guideline development ( 3 ) . Although there was almost unanimous agreement on nearly all recommendations , a minority of the panel ( the authors of this commentary ) disagreed with the recommendation to increase the target systolic blood pressure ( SBP ) from 140 to 150 mm Hg in persons aged 60 years or older without diabetes mellitus ( DM ) or chronic kidney disease ( CKD ) . This target guides both the initiation of therapy and treatment goals . Although this issue has major clinical and public health implication s , the guideline only briefly summarized the concerns underlying the minority opinion to maintain the target of less than 140 mm Hg . The Institute of Medicine recommendation for guideline development encourages guidelines to provide a description and explanation of any differences of opinion regarding the recommendation ( 3 ) . This summarizes the evidence and rationale underlying the minority opinion to maintain the SBP target of 140 mm Hg or lower in persons aged 60 years or older until there is greater certainty of the risks and benefits of a higher target . First , increasing the target will probably reduce the intensity of antihypertensive treatment in a large population at high risk for cardiovascular disease ( CVD ) ( Table 1 ) . The higher SBP goal would apply to some of the groups at highest cardiovascular risk , such as African Americans , hypertensive patients with multiple CVD risk factors other than DM or CKD , and those with clinical CVD . Second , the evidence supporting increasing the SBP target from 140 to 150 mm Hg in persons aged 60 years or older was insufficient and inconsistent with the evidence supporting the panel 's recommendations for an SBP target of less than 140 mm Hg in persons younger than 60 years and those aged 60 years or older with DM or CKD . Third , the higher SBP goal in individuals aged 60 years or older may reverse the decades-long decline in CVD , especially stroke mortality ( 4 ) . In the absence of definitive evidence defining the optimum SBP target , observational studies and RCT data that the panel did not systematic ally review more strongly support the SBP goal of less than 140 mm Hg , especially in high-risk individuals . Other recent guideline groups review ing similar evidence have recommended a goal of less than 140 mm Hg , particularly in persons aged 80 years or younger ( 59 ) . Table 1 . U.S. Cardiovascular Disease Death Rates for Persons Younger and Older Than 65 y Persons Aged 60 Years or Older With Hypertension and SBP Controlled to 140 mm Hg or Lower More than half of the 72 million persons with hypertension in the United States are aged 60 years or older ( 10 , 11 ) . Among these individuals , the 2014 guideline recommends the SBP goal of 140 mm Hg or lower only for those with DM and those younger than 70 years with CKD ( 2 ) . Although the prevalence of hypertension in this age group ( 65 % to 67 % ) did not change between 1999 and 2010 , the percentage with adequate blood pressure control increased from 27.4 % ( 19992000 ) to 50.5 % ( 20112012 ) , with 82.2 % now receiving antihypertensive medications ( 10 , 12 ) . Data from NHANES ( National Health and Nutrition Examination Survey ) from 2001 to 2008 show that among treated and untreated hypertensive adults aged 60 years or older , median SBPs were 136 mm Hg and 152 mm Hg , respectively ( 13 ) , and SBPs have been decreasing in this age group over the past 5 decades ( Figure ) ( 4 ) . Thus , a target of less than 150 mm Hg would likely increase blood pressures in the treated hypertensive population and would suggest that nearly half of the untreated hypertensive patients in this age range should remain untreated . The large population at high risk for CVD , with most currently at an SBP of 140 mm Hg or lower , creates concern that a higher SBP target will adversely affect public health . Figure . Smoothed weighted frequency distribution , median , and 90th percentile of systolic blood pressure for persons aged 60 to 74 y : United States , 19592010 . Reproduced from Lackl and and colleagues ( 4 ) . NHANES = National Health and Nutrition Examination Survey ; NHES = National Health Examination Survey . High Risk in Persons With the Higher Goal Age substantially increases risk for cardiovascular events ( Table 1 ) , so differences in cardiovascular risk do not justify different targets for patients older and younger than 60 years . The risk range for white and African American men aged 60 years is 9 % to 30 % , depending on risk factor profile . For men of both ethnicities who are aged 70 years or older and have SBP controlled to 140 mm Hg , even without clinical CVD or DM , the 10-year risk exceeds 20 % ( 14 ) . Thus , on the basis of absolute risk , using an age threshold of 60 years to define eligibility for less aggressive treatment lacks consistency . Persons aged 60 to 79 years are at higher risk than those who are younger , even if the younger persons have DM . Insufficient Evidence for Differential Hypertension Treatment Benefit for Patients Older and Younger Than 60 Years The 2014 guideline panel failed to identify evidence of differential benefits or harms of treatment using an SBP goal of 140 mm Hg with an age threshold of 60 years . There is little RCT evidence of risk or benefit in treating persons younger than 60 years to this target , except in those with diastolic hypertension . The guideline indicates that no qualifying evidence was found comparing an SBP less than 140 mm Hg to any other SBP goal for persons younger than 60 years ( 2 ) . However , in persons aged 60 years or older , the SHEP ( Systolic Hypertension in the Elderly Program ) trial showed benefit of treating hypertension to an SBP goal between 140 and 145 mm Hg ( Table 2 ) ( 15 ) . HYVET ( Hypertension in the Very Elderly Trial ) found a benefit of an SBP target of less than 150 mm Hg on health outcomes , including mortality in persons aged 80 years or older ( 16 ) . Patients in the HYVET treatment group achieved an SBP of 144 mm Hg at 2 years compared with 159 mm Hg in the control group , and blood pressures continued to decrease in both groups until the end of the trial . Therefore , HYVET and the SHEP trial provide evidence that reducing SBP to around 140 mm Hg has substantial benefit without major harm in older persons . Thus , the best evidence available for an SBP target around 140 mm Hg , which meets the guideline RCT criteria , is in persons older than 60 years . The lack of benefit seen in 2 Japanese trials in older individuals ( JATOS [ Japanese Trial to Assess Optimal Systolic Blood Pressure in Elderly Hypertensive Patients ] [ 17 ] and the VALISH [ Valsartan in Elderly Isolated Systolic Hypertension ] trial [ 18 ] ) was cited by some to rationalize the higher SBP target , but these trials were underpowered ( Table 2 ) . The SHEP trial and HYVET together reported 365 strokes and more than 285 coronary heart disease events , whereas JATOS and the VALISH trial only had a combined total of 125 strokes and 67 coronary heart disease events . In addition , the much larger FEVER ( Felodipine Event Reduction ) trial ( 19 ) did not meet criteria for inclusion in the panel 's deliberation ( Table 2 ) . This trial , which was conducted in a Chinese population ( age range , 50 to 79 years ; mean age , 62 years ) , reported a significant 27 % reduction in its primary outcome , as well as significant reductions in all CVD , total mortality , coronary heart disease , and heart failure in patients treated to an SBP of 137 mm Hg with a thiazide diureticcalcium-channel blocker combination versus 143 mm Hg with a thiazide diuretic plus placebo ( 19 ) . Table 2 . Trials Comparing Different Systolic Blood Pressure Thresholds In addition , generalizability of the Japanese trials to other population s of patients older than 60 years , such as African Americans , is uncertain . African Americans are at highest risk for all complications of hypertension and are historically undertreated . Thus , we believe that recommending less aggressive targets in this or other high-risk population s requires stronger justification than the guideline cites . Three recent guidelines from other countries have concluded that the appropriate cut point for an age-related differential SBP goal is 80 years or older ( 57 ) . We agree that this higher treatment target in frail hypertensive patients aged 80 years or older better reflects existing evidence . Safety and Adverse Event Risk in Hypertensive Patients Aged 60 Years or Older Despite the limited number of end points in JATOS and the VALISH trial , their size and duration provide evidence of safety of the SBP target of less than 140 mm Hg . The VALISH investigators concluded that this target was safe in relatively healthy patients aged 70 years or older with isolated systolic hypertension ( 18 ) . In JATOS , adverse events requiring treatment discontinuation were reported in only 36 patients , with no differences in discontinuation rate between groups ( 17 ) . This evidence and the favorable results at slightly higher blood pressures in the SHEP trial and HYVET provide reassurance of the safety of an SBP goal of less than 140 mm Hg in older , nonfrail persons . Other Trial Evidence of Benefit of Treatment at an SBP of 140 mm Hg or Lower Results of the SPS3 ( Secondary Prevention of Small Subcortical Strokes ) trial indicated that an SBP target of less than 130 mm Hg versus 144 mm Hg in 3020 patients ( mean age , 63 years ) reduced subsequent strokes by 19 % ( P= 0.08 ) and hemorrhagic strokes by nearly 50 % ( P < 0.01 ) ( 20 ) . Of note , the FEVER trial reported a 44 % ( P < 0.001 ) reduction in all strokes in a subgroup analysis of patients older than 65 years ( 17 ) . Finally , 2 meta-analyses In 1972 - -1973 , 785 symptom-free men , aged 40 to 49 years , without target organ damage , with systolic blood pressures between 150 and 179 mm Hg and diastolic blood pressure below 110 mm Hg , were assigned at r and om to one of two groups : ( 406 to a drug treatment group and 379 to a control group ) for a five-year controlled drug treatment trial to evaluate the effect of therapy on cardiovascular complications . Drug treatment started with hydrochlorothiazide . If systolic blood pressure remained above 140 mm Hg and /or diastolic blood pressure above 90 mm Hg , alphamethyldopa was added . If there were side effects , methyldopa was replaced with propranolol . The control group was not given a placebo . The mean observation time was 66 months ( range 60 to 78 months ) . A difference in blood pressure between groups of about 17 mm Hg systolic and 10 mm Hg diastolic was maintained throughout the study . The study protocol had a rather low " ethical " blood pressure roof , 180 mm Hg systolic and /or 110 mm Hg diastolic . Seventeen percent of the control group had an increase in blood pressure above this level during the trial , and drug treatment was started . There was no effect on major cardiovascular morbidity comparing groups as established by r and omization , with 18 events in the treatment group and 20 events in the control group . There was no difference between the groups in total mortality and mortality from cardiovascular events . However , in the subgroups with diastolic blood pressure greater than or equal to 100 mm Hg before r and omization , there was a probable reduction in total morbidity from cardiovascular events in favor or the group receiving drug therapy , 7.6 and 16.4 percent events in the treated and control groups , respectively . Cerebrovascular events occurred only in the control group , 7 versus 0 . Two cases of fatal aortic aneurysms also occurred in the control group . Other " pressure " complications , such as marked left ventricular hypertrophy in the electrocardiogram and left ventricular failure , occurred only in the control group . However , regarding coronary heart disease , including sudden death , the incidence tended to be higher in the treated group , although it was not statistically significant . Only 13 men ( 1.7 percent ) failed to meet for regular examinations . At the end of the study these men were also followed up with regard to possible cardiovascular events OBJECTIVE --To establish whether treatment with diuretic or beta blocker in hypertensive older adults reduces risk of stroke , coronary heart disease , and death . DESIGN --R and omised , placebo controlled , single blind trial . SETTING --226 general practice s in the MRC general practice research framework . SUBJECTS--4396 patients aged 65 - 74 r and omised to receive diuretic , beta blocker , or placebo . Patients had mean systolic pressures of 160 - 209 mm Hg and mean diastolic pressures less than 115 mm Hg during an eight week run in and were not taking antihypertensive treatment . INTERVENTION-- Patients were r and omised to atenolol 50 mg daily ; hydrochlorothiazide 25 mg or 50 mg plus amiloride 2.5 mg or 5 mg daily ; or placebo . The regimens were adjusted to achieve specified target pressures . Mean follow up was 5.8 years . MAIN OUTCOME MEASURES --Strokes , coronary events , and deaths from all causes . RESULTS --Both treatments reduced blood pressure below the level in the placebo group . Compared with the placebo group , actively treated subjects ( diuretic and beta blocker groups combined ) had a 25 % ( 95 % confidence interval 3 % to 42 % ) reduction in stroke ( p = 0.04 ) , 19 % ( -2 % to 36 % ) reduction in coronary events ( p = 0.08 ) , and 17 % ( 2 % to 29 % ) reduction in all cardiovascular events ( p = 0.03 ) . After adjusting for baseline characteristics the diuretic group had significantly reduced risks of stroke ( 31 % ( 3 % to 51 % ) p = 0.04 ) , coronary events ( 44 % ( 21 % to 60 % ) , p = 0.0009 ) , and all cardiovascular events ( 35 % ( 17 % to 49 % ) , p = 0.0005 ) compared with the placebo group . The beta blocker group showed no significant reductions in these end points . The reduction in strokes was mainly in non-smokers taking the diuretic . CONCLUSION --Hydrochlorothiazide and amiloride reduce the risk of stroke , coronary events , and all cardiovascular events in older hypertensive adults BACKGROUND Although several important studies have been performed in hypertensive type 2 diabetic patients , it is not known whether lowering blood pressure in normotensive ( BP < 140/90 mm Hg ) patients offers any beneficial results on vascular complications . The current study evaluated the effect of intensive versus moderate diastolic blood pressure ( DBP ) control on diabetic vascular complications in 480 normotensive type 2 diabetic patients . METHODS The current study was a prospect i ve , r and omized controlled trial in normotensive type 2 diabetic subjects . The subjects were r and omized to intensive ( 10 mm Hg below the baseline DBP ) versus moderate ( 80 to 89 mm Hg ) DBP control . Patients in the moderate therapy group were given placebo , while the patients r and omized to intensive therapy received either nisoldipine or enalapril in a blinded manner as the initial antihypertensive medication . The primary end point evaluated was the change in creatinine clearance with the secondary endpoints consisting of change in urinary albumin excretion , progression of retinopathy and neuropathy and the incidence of cardiovascular disease . RESULTS The mean follow-up was 5.3 years . Mean BP in the intensive group was 128 + /- 0.8/75 + /- 0.3 mm Hg versus 137 + /- 0.7/81 + /- 0.3 mm Hg in the moderate group , P < 0.0001 . Although no difference was demonstrated in creatinine clearance ( P = 0.43 ) , a lower percentage of patients in the intensive group progressed from normoalbuminuria to microalbuminuria ( P = 0.012 ) and microalbuminuria to overt albuminuria ( P = 0.028 ) . The intensive BP control group also demonstrated less progression of diabetic retinopathy ( P = 0.019 ) and a lower incidence of strokes ( P = 0.03 ) . The results were the same whether enalapril or nisoldipine was used as the initial antihypertensive agent . CONCLUSION Over a five-year follow-up period , intensive ( approximately 128/75 mm Hg ) BP control in normotensive type 2 diabetic patients : ( 1 ) slowed the progression to incipient and overt diabetic nephropathy ; ( 2 ) decreased the progression of diabetic retinopathy ; and ( 3 ) diminished the incidence of stroke OBJECTIVES We attempted to compare the effect of an angiotensin-converting enzyme ( ACE ) inhibitor and angiotensin receptor blocker ( ARB ) on  atherosclerotic events . BACKGROUND Angiotensin-converting enzyme inhibitors and ARBs interrupt the renin-angiotensin system by distinct mechanisms . It is not clear whether ARBs reduce atherosclerotic events such as myocardial infa rct ion ( MI ) like ACE inhibitors . This evidence gap may reflect the nature of the studies conducted , to date . Placebo-controlled studies enrolled cohorts at low risk of atherosclerotic events ( e.g. , patients with chronic heart failure , most treated with an ACE inhibitor ) . One of the main active controlled trials was confounded by a blood pressure difference between treatments . METHODS We compared the effects of captopril , valsartan , and their combination on atherosclerotic events in 14,703 patients r and omized in the Valsartan in Acute Myocardial Infa rct ion Trial ( VALIANT ) . RESULTS The number of individuals adjudicated as having a fatal or non-fatal MI in the captopril group was 559 ( total investigator reported events 798 ) , 587 ( 796 ) in the valsartan group , and 554 ( 756 ) in the combination group ; valsartan versus captopril , p = 0.651 ( 0.965 ) ; combination versus captopril , p = 0.187 ( 0.350 ) . Overall , all atherosclerotic events examined occurred at a similar frequency in the captopril and valsartan groups . CONCLUSIONS Angiotensin receptor blockers appear to be as effective as ACE inhibitors in reducing atherosclerotic events , even when used in addition to other secondary preventive treatments . These data , although not conclusive , also support the hypothesis that adding an ARB to an ACE inhibitor may have a small additional anti-infa rct ion effect , a possibility that needs to be prospect ively tested BACKGROUND It is unknown whether high-dose angiotensin II receptor blocker therapy or angiotensin II receptor blocker + calcium channel blocker combination therapy is better in elderly hypertensive patients with high cardiovascular risk . The objective of the study was to compare the efficacy of these treatments in elderly , high-risk Japanese hypertensive patients . METHODS The OlmeSartan and Calcium Antagonists R and omized ( OSCAR ) study was a multicenter , prospect i ve , r and omized , open-label , blinded-end point study of 1164 hypertensive patients aged 65 to 84 years with type 2 diabetes or cardiovascular disease . Patients with uncontrolled hypertension during treatment with olmesartan 20 mg/d were r and omly assigned to receive 40 mg/d olmesartan ( high-dose angiotensin II receptor blocker ) or a calcium channel blocker + 20 mg/d olmesartan ( angiotensin II receptor blocker + calcium channel blocker ) . The primary end point was a composite of cardiovascular events and noncardiovascular death . RESULTS During a 3-year follow-up , blood pressure was significantly lower in the angiotensin II receptor blocker + calcium channel blocker group than in the high-dose angiotensin II receptor blocker group . Mean blood pressure at 36 months was 135.0/74.3 mm Hg in the high-dose angiotensin II receptor blocker group and 132.6/72.6 mm Hg in the angiotensin II receptor blocker + calcium channel blocker group . More primary end points occurred in the high-dose angiotensin II receptor blocker group than in the angiotensin II receptor blocker + calcium channel blocker group ( 58 vs 48 events , hazard ratio [ HR ] , 1.31 , 95 % confidence interval , 0.89 - 1.92 ; P=.17 ) . In patients with cardiovascular disease at baseline , more primary events occurred in the high-dose angiotensin II receptor blocker group ( HR , 1.63 , P=.03 ) ; in contrast , fewer events were observed in the subgroup without cardiovascular disease ( HR , 0.52 , P=.14 ) . This treatment-by-subgroup interaction was significant ( P=.02 ) . CONCLUSION The angiotensin II receptor blocker and calcium channel blocker combination lowered blood pressure more than the high-dose angiotensin II receptor blocker and reduced the incidence of primary end points more than the high-dose angiotensin II receptor blocker in patients with cardiovascular disease . The addition of a second antihypertensive agent is more effective at lowering blood pressure than simply doubling the dose of an existing agent Background Isolated systolic hyprtension occurs in around 8 % of Chinese people aged 60 years or older . In 1988 , the Systolic Hypertension in China ( Syst-China ) Collaborative Group started to investigate whether active treatment could reduce the incidence of stroke and other cardiovascular complications in older patients with isolated systolic hypertension . Methods All patients were initially started on masked placebo . After stratification for centre , sex and previous cardiovascular complications , alternate patients ( n = 1253 ) were assigned nitrendipine at 10–40 mg daily , with the addition of captopril at 12.5–50.0 mg daily or hydrochlorothiazide at 12.5–50.0 mg daily , or both , if a sufficient blood pressure fall was not obtained . In the remaining 1141 control patients , matching placebos were administered similarly . Results At entry , sitting blood pressure averaged 170.5 mmHg systolic and 86.0 mmHg diastolic , age averaged 66.5 years and total serum cholesterol was 5.1 mmol/l . After 2 years of follow-up , sitting systolic and diastolic blood pressures had fallen by 10.9 mmHg and 1.9 mmHg in the placebo group and by 20.0 mmHg and 5.0 mmHg in the active treatment group . The intergroup differences were 9.1 mmHg systolic ( 95 % confidence interval 7.6–10.7 mmHg ) and 3.2 mmHg diastolic ( 95 % confidence interval 2.4–4.0 ) . Active treatment reduced total strokes by 38 % ( from 20.8 to 13.0 endpoints per 1000 patient-years , P = 0.01 ) , all-cause mortality by 39 % ( from 28.4 to 17.4 endpoints per 1000 patient-years , P = 0.003 ) , cardiovascular mortality by 39 % ( from 15.2 to 9.4 endpoints per 1000 patient-years , P = 0.03 ) , stroke mortality by 58 % ( from 6.9 to 2.9 endpoints per 1000 patient-years , P = 0.02 ) , and all fatal and nonfatal cardiovascular endpoints by 37 % ( from 33.3 to 21.4 endpoints per 1000 patient-years , P = 0.004 ) . Conclusions Antihypertensive treatment prevents stroke and other cardiovascular complications in older Chinese patients with isolated systolic hypertension . Treatment of 1000 Chinese patients for 5 years could prevent 55 deaths , 39 strokes or 59 major cardiovascular endpoints Men aged 40 - 64 years with mild to moderate hypertension [ diastolic blood pressure ( DBP ) 100 - 130 mmHg ] were r and omized to treatment with a  diuretic ( n = 3272 ) or a  beta-blocker ( n = 3297 ) , with additional drugs if necessary , to determine whether a beta-blocker based treatment differs from thiazide diuretic based treatment with regard to the prevention of coronary heart disease ( CHD ) events and death .  Patients with previous CHD , stroke or other serious diseases , or with contraindications to diuretics or beta-blockers were excluded . If normotension ( DBP less than 95 mmHg ) was not achieved by monotherapy , other antihypertensive drugs were added , but the two basic drugs were not crossed over . Patients were assessed at 6-monthly intervals . The mean follow-up for end-points was 45.1 months . Blood pressure ( BP ) side effects and end-points were recorded in a st and ardized manner . Entry characteristics and the BP reduction achieved were very similar in both treatment groups . All analyses were made on an intention-to-treat basis . The incidence of CHD did not differ between the two treatment groups . The incidence of fatal stroke tended to be lower in the beta-blocker treated group than in the diuretic treated group . Total mortality and the total number of end-points were similar in both groups . The percentage of patients withdrawn due to side effects was similar , whereas the number of reported symptoms , according to a question naire , was higher for patients on beta-blockers . The incidence of diabetes did not differ between the two groups . Subgroup analyses did not detect a difference in the effect of beta-blockers compared with diuretics in smokers as opposed to non-smokers , and beta-blockers also had the same effects as diuretics in the quartile with the highest predicted risk for CHD . Beta-blockers and thiazide diuretics were approximately equally well tolerated . The two drugs had a similar BP reducing effect although additional drugs had to be given more often in the diuretic group . Antihypertensive treatment based on a beta-blocker or on a thiazide diuretic could not be shown to affect the prevention of hypertensive complications , including CHD , to a different extent ABCD :

The 2013 guidelines on hypertension of the European Society of Hypertension ( ESH ) and the European Society of Cardiology Hypertension is the most common condition seen in primary care and leads to myocardial infa rct ion , stroke , renal failure , and death if not detected early and treated appropriately . Patients want to be assured that blood pressure ( BP ) treatment will reduce their disease burden , while clinicians want guidance on hypertension management using the best scientific evidence . This report takes a rigorous , evidence -based approach to recommend treatment thresholds , goals , and medications in the management of hypertension in adults . Evidence was drawn from r and omized controlled trials , which represent the gold st and ard for determining efficacy and effectiveness . Evidence quality and recommendations were grade d based on their effect on important outcomes . There is strong evidence to support treating hypertensive persons aged 60 years or older to a  BP goal  of less than 150/90 mm Hg and hypertensive persons 30 through 59 years of age to a diastolic goal of less than 90 mm Hg ; however , there is insufficient evidence in hypertensive persons younger than 60 years for a systolic goal , or in those younger than 30 years for a diastolic goal , so the panel recommends a BP of less than 140/90 mm Hg for those groups based on expert opinion . The same thresholds and goals are recommended for hypertensive adults with diabetes or nondiabetic chronic kidney disease ( CKD ) as for the general hypertensive population younger than 60 years . There is moderate evidence to support initiating drug treatment with an angiotensin-converting enzyme inhibitor , angiotensin receptor blocker , calcium channel blocker , or thiazide-type diuretic in the nonblack hypertensive population , including those with diabetes . In the black hypertensive population , including those with diabetes , a calcium channel blocker or thiazide-type diuretic is recommended as initial therapy . There is moderate evidence to support initial or add-on antihypertensive therapy with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in persons with CKD to improve kidney outcomes . Although this guideline provides evidence -based recommendations for the management of high BP and should meet the clinical needs of most patients , these recommendations are not a substitute for clinical judgment , and decisions about care must carefully consider and incorporate the clinical characteristics and circumstances of each individual patient
target: There was no clear evidence that proportional risk reductions in major cardiovascular disease differed by baseline disease history , except for diabetes and chronic kidney disease , for which smaller , but significant , risk reductions were detected .
  β blockers were inferior to other drugs for the prevention of major cardiovascular disease events , stroke , and renal failure .
  Calcium channel blockers were superior to other drugs for the prevention of stroke .
  For the prevention of heart failure , calcium channel blockers were inferior and diuretics were superior to other drug classes .
  INTERPRETATION Blood pressure lowering significantly reduces vascular risk across various baseline blood pressure levels and comorbidities .
background: BACKGROUND The benefits of blood pressure lowering treatment for prevention of cardiovascular disease are well established .
  However , the extent to which these effects differ by baseline blood pressure , presence of comorbidities , or drug class is less clear .
  We therefore performed a systematic review and meta- analysis to clarify these differences .
