abstract: Of 22 r and omized trials of rehabilitation with exercise  after myocardial infa rct ion ( MI ) , one trial had results that achieved conventional statistical significance . To determine whether or not these studies , in the aggregate , show a significant benefit of rehabilitation after myocardial infa rct ion , we performed an overview of all r and omized trials , involving 4,554 patients ; we evaluated total and cardiovascular mortality , sudden death , and fatal and nonfatal reinfa rct ion . For each endpoint , we calculated an odds ratio ( OR ) and 95 % confidence interval ( 95 % CI ) for the trials combined . After an average of 3 years of follow-up , the ORs were significantly lower in the rehabilitation than in the comparison group : specifically , total mortality ( OR = 0.80 [ 0.66 , 0.96 ] ) , cardiovascular mortality ( OR = 0.78 [ 0.63 , 0.96 ] ) , and fatal reinfa rct ion ( OR = 0.75 [ 0.59 , 0.95 ] ) . The OR for sudden death was significantly lower in the rehabilitation than in the comparison group at 1 year ( OR = 0.63 [ 0.41 , 0.97 ] ) . The data were compatible with a benefit at 2 ( OR = 0.76 [ 0.54 , 1.06 ] ) and 3 years ( OR = 0.92 [ 0.69 , 1.23 ] ) , but these findings were not statistically significant . For nonfatal reinfa rct ion , there were no significant differences between the two groups after 1 ( OR = 1.09 [ 0.76 , 1.57 ] ) , 2 ( OR = 1.10 [ 0.82 , 1.47 ] ) , or 3 years ( OR = 1.09 [ 0.88 , 1.34 ] ) of follow-up . The observed 20 % reduction in overall mortality reflects a decreased risk of cardiovascular mortality and fatal reinfa rct ion throughout at least 3 years and a reduction in sudden death during the 1st year after infa rct ion and possibly for 2 - 3 years . With respect to the independent effects of the physical exercise component of cardiac rehabilitation , the relatively small number of " exercise only " trials , combined with the possibility that they may have had a formal or informal nonexercise component precludes the possibility of reaching any definitive conclusion . To do so would require a r and omized trial of sufficient size to distinguish between no effect and the most plausible effect based on the results of this overview Background Significant regression of coronary and femoral atherosclerotic lesions has been documented by angiographic studies using aggressive lipid-lowering treatment . This study tested the applicability and effects of intensive physical exercise and low-fat diet on coronary morphology and myocardial perfusion in nonselected patients with stable angina pectoris . Methods and Results Patients were recruited after routine coronary angiography for stable angina pectoris ; they were r and omized to an  intervention group ( n = 56 ) and a  control group on “ usual care ” ( n = 57 ) . Treatment comprised intensive physical exercise in group training sessions ( minimum , 2 hr/wk ) , daily home exercise periods ( 20 min/d ) , and low-fat , low-cholesterol diet ( American Heart Association recommendation , phase 3 ) . No lipid-lowering agents were prescribed . After 12 months of participation , repeat coronary angiography was performed ; relative and minimal diameter reductions of coronary lesions were measured by digital image processing . Change in myocardial perfusion was assessed by 201TI scintigraphy . In patients participating in the intervention group , body weight decreased by 5 % ( p<0.001 ) , total cholesterol by 10 % ( p<0.001 ) , and triglycerides by 24 % ( p<0.001 ) ; high density lipoproteins increased by 3 % ( p = NS ) . Physical work capacity improved by 23 % ( p<0.0001 ) , and myocardial oxygen consumption , as estimated from maximal rate-pressure product , by 10 % , ( p<0.05 ) . Stress-induced myocardial ischemia decreased concurrently , indicating improvement of myocardial perfusion . Based on minimal lesion diameter , progression of coronary lesions was noted in nine patients ( 23 % ) , no change in 18 patients ( 45 % ) , and regression in 13 patients ( 32 % ) . In the control group , metabolic and hemodynamic variables remained essentially unchanged , whereas progression of coronary lesions was noted in 25 patients ( 48 % ) , no change in 18 patients ( 35 % ) , and regression in nine patients ( 17 % ) . These changes were significantly different from the intervention group ( p<0.05 ) . Conclusions In patients participating in regular physical exercise and low-fat diet , coronary artery disease progresses at a slower pace compared with a control group on usual care Abstract Objective : To evaluate the effects of secondary prevention clinics run by nurses in general practice on the health of patients with coronary heart disease . Design : R and omised controlled trial of clinics over one year with assessment by self completed postal question naires and audit of medical records at the start and end of the trial . Setting : R and om sample of 19 general practice s in northeast Scotl and . Subjects : 1173 patients ( 685 men and 488 women ) under 80 years with working diagnoses of coronary heart disease who did not have terminal illness or dementia and were not housebound . Intervention : Clinic staff promoted medical and lifestyle aspects of secondary prevention and offered regular follow up . Main outcome measures : Health status measured by the SF-36 question naire , chest pain by the angina type specification , and anxiety and depression by the hospital anxiety and depression scale . Use of health services before and during the study . Results : There were significant improvements in six of eight health status domains ( all functioning scales , pain , and general health ) among patients attending the clinic . Role limitations attributed to physical problems improved most ( adjusted difference 8.52 , 95 % confidence interval 4.16 to 12.9 ) . Fewer patients reported worsening chest pain ( odds ratio 0.59 , 95 % confidence interval 0.37 to 0.94 ) . There were no significant effects on anxiety or depression . Fewer intervention group patients required hospital admissions ( 0.64 , 0.48 to 0.86 ) , but general practitioner consultation rates did not alter . Conclusions : Within their first year secondary prevention clinics improved patients ' health and reduced hospital admissions . Key messages Nurse led clinics in general practice were used to promote secondary prevention to patients with coronary heart disease Within the first year the health of patients invited to the clinics improved Most benefit was in functional status , but chest pain improved too There was no effects on anxiety or depression There were significant reductions in hospital admissions in the first BACKGROUND The Lyon Diet Heart Study is a r and omized secondary prevention trial aim ed at testing whether a Mediterranean-type diet may reduce the rate of recurrence  after a first myocardial infa rct ion . An intermediate analysis showed a striking protective effect after 27 months of follow-up . This report presents results of an extended follow-up ( with a mean of 46 months per patient ) and deals with the relationships of dietary patterns and traditional risk factors with recurrence . METHODS AND RESULTS Three composite outcomes ( COs ) combining either cardiac death and nonfatal myocardial infa rct ion ( CO 1 ) , or the preceding plus major secondary end points ( unstable angina , stroke , heart failure , pulmonary or peripheral embolism ) ( CO 2 ) , or the preceding plus minor events requiring hospital admission ( CO 3 ) were studied . In the  Mediterranean diet group , CO 1 was reduced ( 14 events versus 44 in the prudent Western-type diet group , P=0.0001 ) , as were CO 2 ( 27 events versus 90 , P=0.0001 ) and CO 3 ( 95 events versus 180 , P=0 . 0002 ) . Adjusted risk ratios ranged from 0.28 to 0.53 . Among the traditional risk factors , total cholesterol ( 1 mmol/L being associated with an increased risk of 18 % to 28 % ) , systolic blood pressure ( 1 mm Hg being associated with an increased risk of 1 % to 2 % ) , leukocyte count ( adjusted risk ratios ranging from 1.64 to 2.86 with count > 9x10(9)/L ) , female sex ( adjusted risk ratios , 0.27 to 0 . 46 ) , and aspirin use ( adjusted risk ratios , 0.59 to 0.82 ) were each significantly and independently associated with recurrence . CONCLUSIONS The protective effect of the Mediterranean dietary pattern was maintained up to 4 years after the first infa rct ion , confirming previous intermediate analyses . Major traditional risk factors , such as high blood cholesterol and blood pressure , were shown to be independent and joint predictors of recurrence , indicating that the Mediterranean dietary pattern did not alter , at least qualitatively , the usual relationships between major risk factors and recurrence . Thus , a comprehensive strategy to decrease cardiovascular morbidity and mortality should include primarily a cardioprotective diet . It should be associated with other ( pharmacological ? ) means aim ed at reducing modifiable risk factors . Further trials combining the 2 approaches are warranted Objective To evaluate whether  nurse run clinics in general practice improve secondary prevention in patients with coronary heart disease . Design R and omised controlled trial . Setting A r and om sample of 19 general practice s in northeast Scotl and . Patients 1173 patients ( 685 men and 488 women ) under 80 years with working diagnoses of coronary heart disease , but without terminal illness or dementia and not housebound .  Intervention Nurse run clinics promoted medical and lifestyle aspects of secondary prevention and offered regular follow up . Main outcome measures Components of secondary prevention assessed at baseline and one year were : aspirin use ; blood pressure management ; lipid management ; physical activity ; dietary fat ; and smoking status . A cumulative score was generated by counting the number of appropriate components of secondary prevention for each patient . Results There were significant improvements in aspirin management ( odds ratio 3.22 , 95 % confidence interval 2.15 to 4.80 ) , blood pressure management ( 5.32 , 3.01 to 9.41 ) , lipid management ( 3.19 , 2.39 to 4.26 ) , physical activity ( 1.67 , 1.23 to 2.26 ) and diet ( 1.47 , 1.10 to 1.96 ) . There was no effect on smoking cessation ( 0.78 , 0.47 to 1.28 ) . Of six possible components of secondary prevention , the baseline mean was 3.27 . The adjusted mean improvement attributable to intervention was 0.55 of a component ( 0.44 to 0.67 ) . Improvement was found regardless of practice baseline performance . Conclusions  Nurse run clinics proved practical to implement in general practice and effectively increased secondary prevention in coronary heart disease . Most patients gained at least one effective component of secondary prevention and , for them , future cardiovascular events and mortality could be reduced by up to a third Coronary artery diseases ( CAD ) are main causes of morbidity and hospitalisation in western countries and CAD patients are at considerable risk of suffering further cardiac events . The development and evaluation of secondary prevention programmes therefore an important task . This thesis includes investigations on CAD patients admitted to a secondary prevention programme at Malmö University Hospital , Malmö , Sweden . Four weeks after discharge from the hospital , consecutive male and female patients aged 50 - 70 years with acute myocardial infa rct ion ( AMI ) or treated with coronary artery bypass grafting ( CABG ) surgery  were r and omised to a hospital organised preventive intervention or to usual follow-up at their general practitioners . In the three studies using this r and omised design , 87 ( study II ) , 90 ( study IV ) , and 106 ( study V ) intervention patients were available for evaluation . In addition , without r and omisation , lipid levels at four weeks after the event was compared with levels estimated within 24 hours after onset of symptoms in 141 AMI patients ( study I ) , and quality of life ( QL ) were estimated by question naire at one month and at one year after the event in 266 AMI , 94 CABG , and 16 percutaneous transluminal coronary angioplasty ( PTCA ) patients ( study III ) . The prevention programme was effective in improving food habits but showed no impact on smoking habits or physical exercise in AMI patients ( study II ) . The intervention also did not show any significant improvement in working capacity in AMI and CABG patients . However , working capacity improved in both intervention and reference CABG patients , most probably due to improved coronary circulation from the surgery ( study IV ) . Cholesterol levels decreased significantly in AMI and CABG intervention patients as compared to the corresponding reference patients . This difference most likely was due to a higher frequency of lipid lowering drugs used in the intervention patients ( study V ) . The prevention programme also decreased body mass index significantly in AMI but not in CABG patients ( study V ) . In AMI patients receiving thrombolysis , cholesterol levels estimated within 24 hours after onset of symptoms and at four weeks after the event were virtually equal . In AMI patients not receiving thrombolysis , the lipid estimates from four weeks after the event were slightly , but significantly , above the within 24 hours from onset of symptoms estimates ( study I ) . One month after the event , both somatic and psychological aspects of QL were negatively affected in AMI and CABG patients compared to population controls . One year after the event , patients differed from controls mainly in somatic symptoms ( study III ) . Thus , the intervention programme was most successful in affecting lipid levels and food habits in AMI patients .  QL was considerably affected in patients following an cardiac event , especially during the initial recovery phase . In addition , in patients receiving thrombolysis , cholesterol levels estimated four weeks after an AMI are reasonably valid estimates of baseline values and may be used to decide about lipid lowering interventions Objectives : To evaluate the effects of nurse-led secondary prevention clinics for coronary heart disease ( CHD ) in primary care on total mortality and coronary event rates after 10 years . Design : Follow-up of a r and omised controlled trial by review of national data sets . Setting : Stratified r and om sample of 19 general practice s in northeast Scotl and . Participants : Original study cohort of 1343 patients , aged < 80 years , with a working diagnosis of CHD , but without dementia or terminal illness and not housebound . Intervention : Nurse-led secondary prevention clinics promoted medical and lifestyle aspects of secondary prevention and offered regular follow-up for 1 year , Main outcome measures : Total mortality and coronary events ( non-fatal myocardial infa rct ions ( MIs ) and coronary deaths ) . Results : Mean ( SD ) follow-up was at 10.2 ( 0.19 ) years . No significant differences in total mortality or coronary events were found at 10 years . 254 patients in the intervention group and 277 patients in the control group had died : cumulative death rates were 38 % and 41 % , respectively ( p = 0.177 ) . 196 coronary events occurred in the intervention group and 195 in the control group : cumulative event rates were 29.1 % and 29.1 % , respectively ( p = 0.994 ) . When Kaplan – Meier survival analysis , adjusted for age , sex and general practice , was used , proportional hazard ratios were 0.88 ( 0.74 to 1.04 ) for total mortality and 0.96 ( 0.79 to 1.18 ) for coronary death or non-fatal MI . No significant differences in the distribution of cause of death classifications was found at either 4 or 10 years . Conclusions : After 10 years , differences between groups were no longer significant . Total mortality survival curves for the intervention and control groups had not converged , but the coronary event survival curves had . Possibly , therefore , the earlier that secondary prevention is optimised , the less likely a subsequent coronary event is to prove fatal OBJECTIVES We sought to describe the various cardiovascular complications that occurred in the Lyon Diet Heart Study ( a secondary prevention trial testing the protective effects of a Mediterranean type of diet ) , to analyze their relations with the associated drug treatments and to gain insights into the possible mechanisms underlying the beneficial effects of certain nutriments . BACKGROUND Dietary habits are implicated in coronary heart disease , and the traditional Mediterranean diet is thought to be cardioprotective . However , the exact mechanisms of this protection are unknown . METHODS A total of 605 patients ( 303 control subjects and 302 study patients ) were studied over a mean period of 27 months . Major primary end points ( cardiovascular death and nonfatal acute myocardial infa rct ion ) , secondary end points ( including unstable angina , stroke , heart failure and embolisms ) and minor end points ( stable angina , need for myocardial revascularization , postangioplasty restenosis and thrombophlebitis ) were analyzed separately and in combination . RESULTS When major primary and secondary end points were combined , there were 59 events in control subjects and 14 events in the study patients , showing a risk reduction of 76 % ( p < 0.0001 ) . When these end points were combined with the minor end points , there were 104 events in control subjects and 68 events in the study patients , giving a risk reduction of 37 % ( p < 0.005 ) . By observational analysis , only aspirin among the medications appeared to be significantly protective ( risk ratio after adjustment for prognosis factors 0.45 ; 95 % confidence interval 0.25 to 0.80 ) . CONCLUSIONS These data show a protective effect of the Mediterranean diet . However , the risk reduction varied depending on the type of end point considered . Our hypothesis is that different pathogenetic mechanisms were responsible for the development of the various complications . It is likely that certain nutriments characteristic of the Mediterranean diet ( omega-3 fatty acids , oleic acid antioxidant vitamins ) have specific cardioprotective effects Abstract Objective : To assess the value of health education for patients with angina in reducing risk factors for cardiovascular disease and lessening the effect of angina on everyday activities . Design : R and omised controlled trial of personal health education given every four months . Setting : 18 general practice s in the greater Belfast area . Subjects : 688 patients aged less than 75 years and known to have had angina for at least six months ; 342 r and omised to receive education and 346 to no education .  Main outcome measures : Restriction of everyday activities , dietary habit , smoking habit , frequency of physical exercise ; blood pressure , body mass index , and serum total cholesterol concentration at entry to trial and after two years . Results : 317 in the intervention group and 300 in the control group completed the trial . At the two year review more of the intervention group ( 140 , 44 % ) reported taking daily physical exercise than the control group ( 70 , 24 % ) . The intervention group also reported eating a healthier diet than the control group and less restriction by angina in any everyday activity . No significant differences were found between the groups in smoking habit , systolic or diastolic blood pressure , cholesterol concentration , or body mass index . Conclusion : Despite having no significant effect on objective cardiovascular risk factors , personal health education of patients with angina seems to increase exercise and improve dietary habits and is effective in lessening the restriction of everyday activities CONTEXT The Lifestyle Heart Trial demonstrated that intensive lifestyle changes may lead to regression of coronary atherosclerosis after 1 year . OBJECTIVES To determine the feasibility of patients to sustain  intensive lifestyle changes  for a total of 5 years and the effects of these lifestyle changes ( without lipid-lowering drugs ) on coronary heart disease . DESIGN R and omized controlled trial conducted from 1986 to 1992 using a r and omized invitational design . PATIENTS Forty-eight patients with moderate to severe coronary heart disease were r and omized to an  intensive lifestyle change group  or to a  usual-care control group  , and 35 completed the 5-year follow-up quantitative coronary arteriography . SETTING Two tertiary care university medical centers . INTERVENTION Intensive lifestyle changes ( 10 % fat whole foods vegetarian diet , aerobic exercise , stress management training , smoking cessation , group psychosocial support ) for 5 years . MAIN OUTCOME MEASURES Adherence to intensive lifestyle changes , changes in coronary artery percent diameter stenosis , and cardiac events . RESULTS Experimental group patients ( 20 [ 71 % ] of 28 patients completed 5-year follow-up ) made and maintained comprehensive lifestyle changes for 5 years , whereas control group patients ( 15 [ 75 % ] of 20 patients completed 5-year follow-up ) made more moderate changes . In the experimental group , the average percent diameter stenosis at baseline decreased 1.75 absolute percentage points after 1 year ( a 4.5 % relative improvement ) and by 3.1 absolute percentage points after 5 years ( a 7.9 % relative improvement ) . In contrast , the average percent diameter stenosis in the control group increased by 2.3 percentage points after 1 year ( a 5.4 % relative worsening ) and by 11.8 percentage points after 5 years ( a 27.7 % relative worsening ) ( P=.001 between groups . Twenty-five cardiac events occurred in 28 experimental group patients vs 45 events in 20 control group patients during the 5-year follow-up ( risk ratio for any event for the control group , 2.47 [ 95 % confidence interval , 1.48 - 4.20 ] ) . CONCLUSIONS More regression of coronary atherosclerosis occurred after 5 years than after 1 year in the experimental group . In contrast , in the control group , coronary atherosclerosis continued to progress and more than twice as many cardiac events occurred Objective To test the effectiveness of a complex intervention design ed , within a theoretical framework , to improve outcomes for patients with coronary heart disease . Design Cluster r and omised controlled multicentre trial . Setting General practice s in Northern Irel and and the Republic of Irel and , regions with different healthcare systems . Participants 903 patients with established coronary heart disease registered with one of 48 practice s. Intervention Tailored care plans for practice s ( practice based training in prescribing and behaviour change , administrative support , quarterly newsletter ) , and tailored care plans for patients ( motivational interviewing , goal identification , and target setting for lifestyle change ) with review s every four months at the practice s. Control practice s provided usual care . Main outcome measures The proportion of patients at 18 month follow-up above target levels for blood pressure and total cholesterol concentration , and those admitted to hospital , and changes in physical and mental health status ( SF-12 ) . Results At baseline the numbers ( proportions ) of patients above the recommended limits were : systolic blood pressure greater than 140 mm Hg ( 305/899 ; 33.9 % , 95 % confidence interval 30.8 % to 33.9 % ) , diastolic blood pressure greater than 90 mm Hg ( 111/901 ; 12.3 % , 10.2 % to 14.5 % ) , and total cholesterol concentration greater than 5 mmol/l ( 188/860 ; 20.8 % , 19.1 % to 24.6 % ) . At the 18 month follow-up there were no significant differences between intervention and control groups in the numbers ( proportions ) of patients above the recommended limits : systolic blood pressure , intervention 98/360 ( 27.2 % ) v control , 133/405 ( 32.8 % ) , odds ratio 1.51 ( 95 % confidence interval 0.99 to 2.30 ; P=0.06 ) ; diastolic blood pressure , intervention 32/360 ( 8.9 % ) v control , 40/405 ( 9.9 % ) , 1.40 ( 0.75 to 2.64 ; P=0.29 ) ; and total cholesterol concentration , intervention 52/342 ( 15.2 % ) v control , 64/391 ( 16.4 % ) , 1.13 ( 0.63 to 2.03 ; P=0.65 ) . The number of patients admitted to hospital over the 18 month study period significantly decreased in the intervention group compared with the control group : 107/415 ( 25.8 % ) v 148/435 ( 34.0 % ) , 1.56 ( 1.53 to 2.60 ; P=0.03 ) . Conclusions Admissions to hospital were significantly reduced after an intensive 18 month intervention to improve outcomes for patients with coronary heart disease , but no other clinical benefits were shown , possibly because of a ceiling effect related to improved management of the disease . Trial registration Current Controlled Trials IS RCT N24081411 BACKGROUND There are approximately 1.8 million patients with angina in the United Kingdom , many of whom report a poor quality of life , including raised levels of anxiety and depression . AIM To evaluate the effect of a cognitive behavioural disease management programme , the Angina Plan , on psychological adjustment in patients newly diagnosed with angina pectoris . DESIGN OF STUDY R and omised controlled trial . SETTING Patients from GP practice s in a Northern UK city ( York ) between April 1999 and May 2000 . METHOD Recruited patients were r and omised to receive the Angina Plan or to a routine , practice nurse-led secondary prevention educational session . RESULTS Twenty of the 25 practice s invited to join the study supplied patients ' names ; 142 patients attended an assessment clinic and were r and omised There were no significant differences in any baseline measures . At the six month post-treatment follow-up , 130 ( 91 % ) patients were reassessed . When compared with the educational session patients ( using analysis of covariance adjusted for baseline scores in an intention-to-treat analysis ) Angina Plan patients showed a greater reduction in anxiety ( P = 0.05 ) and depression ( P = 0.01 ) , the frequency of angina ( reduced by three episodes per week , versus a reduction of 0.4 per week , P = 0.016 ) the use of glyceryl trinitrate  ( reduced by 4.19 fewer doses per week versus a reduction of 0.59 per week , P = 0.018 ) , and physical limitations ( P<0.001 : Seattle Angina Question naire ) . They were also more likely to report having changed their diet ( 41 versus 21 , P<0.001 ) and increased their daily walking ( 30 versus 2 , P<0.001 ) . There was no significant difference between the groups on the other sub-scales of the Seattle Angina Question naire or in any of the medical variables measured . CONCLUSION The Angina Plan appears to improve the psychological , symptomatic , and functional status of patients newly diagnosed with angina OBJECTIVE : To examine the ability of a secondary prevention programme to improve the lifestyle in myocardial infa rct ion patients aged 50 - 70 years . DESIGN : Habitual physical activity , food habits , and smoking habits were assessed from question naires at admission to hospital and at the one year follow up . Initially , all patients were invited to join an exercise programme and were informed about cardiovascular risk factors . Four weeks after discharge from the hospital , 87 patients were r and omised to follow up at the coronary prevention unit by a special trained nurse ( the intervention group )  , and 81 to follow up by their general practitioners (  the  usual care group ) . After r and omisation , the intervention group was educated about the effects of smoking cessation , dietary management , and regular physical activity . The intervention group also participated in a physical training programme two to three times weekly for 10 - 12 weeks . MAIN RESULTS : 89 % of the patients referred to the intervention group improved their food habits compared with 62 % of the patients referred to the usual care group ( P = 0.008 ) . Furthermore , 50 % of the smokers referred to the intervention group stopped smoking compared to 29 % in the usual care group ( P = 0.09 ) . Changes in physical activity did not differ between the groups . CONCLUSIONS : This secondary prevention programme based on a nurse rehabilitator was successful in improving food habits in patients with acute myocardial infa rct ion . Initiating the smoking cessation programme during the hospital stay followed by repeated counselling during follow up might have improved the results . The exercise programme had no advantage in supporting physical activity compared to usual care In patients with coronary artery disease ( CAD ) , a rate of restenosis as high as 50 % is observed after percutaneous transluminal coronary angioplasty ( PTCA ) . Frequently , this results in further revascularization procedures . Lifestyle intervention has been shown to slow the progression of CAD and to reduce cardiovascular events after myocardial infa rct ion . However , no information exists whether such treatment influences the rate of restenosis in patients with CAD . The present study was performed to investigate the effects of an intensified lifestyle intervention on the need for further revascularization procedures in patients with established CAD after successful PTCA BACKGROUND The long-term effects of disease management programmes for coronary heart disease on health status are unknown . In a r and omized trial of nurse-led secondary prevention clinics , we found significantly improved health status at 1 year . Participants were followed-up again at 4 years to determine if improvements had been sustained . OBJECTIVE Our aim was to evaluate the effects on health of  nurse-led clinics for the secondary prevention of coronary heart disease in primary care . METHODS A total of 1343 patients with coronary heart disease were r and omized to nurse-led secondary prevention clinics or usual care  , with follow-up at 1 and 4 years by review of medical case notes and national data sets , and postal question naires . The study involved a stratified , r and om sample of 19 general practice s in north-east Scotl and .  Health status was measured by the SF-36 question naire , chest pain by the angina TyPE specification and anxiety and depression by the hospital anxiety and depression scale . RESULTS At 1 year , there were significant improvements in five of eight SF-36 domains ( all functioning scales , pain and general health ) in patients r and omized to clinics . Role limitations attributed to physical problems improved the most [ adjusted difference 8.52 , 95 % confidence interval ( CI ) 4.16 - 12.9 ] . At 4 years , the intervention group scored higher than control in all domains , but differences were no longer significant . At 1 year , fewer patients in the intervention group reported worsening chest pain ( odds ratio 0.59 , 95 % C1 0.37 - 0.94 ) . At 4 years , there were no significant differences between the proportion of intervention or control group patients who reported chest pain in the last week or who reported worsening chest pain . No significant effects were observed on anxiety or depression at 1 or 4 years . CONCLUSION We have demonstrated previously a significantly greater survival in attendees at nurse-led secondary prevention clinics . Despite this , improvements in health status achieved in the first year of the study were reduced at 4 years . The case for nurse-led clinics remains strong , but further research is required on ways to optimize current health status BACKGROUND Most studies that have analysed the effect of secondary prevention of coronary heart disease come from hospitals . Those that are community-based have been conducted mainly by nurses and follow-up was generally too short to show impact on cardiovascular events . METHODS This is a multi-centre r and omised controlled clinical trial in which patients in the intervention group received periodic postal reminders to see their general practitioner every three months during a 3-year follow-up . General practitioners reinforced healthy lifestyle recommendations to patients and review ed drug therapies at these quarterly intervals . Patients in the control group  received usual care . RESULTS A total of 983 patients aged 30 - 79 were included . During the 3-year follow-up , 67 patients died and 156 experienced a non-fatal cardiovascular event . The event rates and all-cause mortality were similar in the intervention and control groups ( 24.0 % and 23.5 % , and 8.1 % and 9.9 % , respectively ) . Improvement in quality of life was similar in both groups . Blood pressure and high-density lipoprotein cholesterol were more frequently within recommended levels in the intervention group than in controls : odds ratio 1.63 , 95 % confidence interval 1.05 - 2.51 , and odds ratio 2.61 , 95 % confidence interval 1.32 - 5.18 , respectively . CONCLUSIONS Intensive secondary prevention conducted by general practitioners may improve long-term blood pressure control and increase high-density lipoprotein cholesterol in patients with stable coronary disease The study was set up to evaluate the long-term effects on mortality of a comprehensive rehabilitation and secondary prevention programme lasting 3 years after acute myocardial infa rct ion . The study group consisted of 375 consecutive , non-selected patients under 65 years of age r and omly allocated to an intervention group ( 188 patients ) or a control group ( 187 patients ) . After 15 years follow-up significantly lower incidence of sudden death ( 16.5 % vs 28.9 % , P = 0.006 ) and coronary mortality ( 47.9 % vs 58.5 % , P = 0.04 ) were seen in the intervention group compared with controls . Total mortality was 64.4 % and 66.8 % , respectively ( ns ) . The incidence of cancer death was 16 in the intervention group and three in the controls . Cardiac failure , enlarged heart , New York Heart Association functional class II or more and membership in the control group were significantly associated with coronary mortality during the first 3 years , and after 3 years enlarged heart , diabetes and reinfa rct ion were associated with late coronary death . Thus , comprehensive multifactorial intervention after acute myocardial infa rct ion had favourable long-term effects on coronary mortality and sudden death but no effect on total mortality R and omized clinical trials of cardiac rehabilitation following myocardial infa rct ion have typically demonstrated a lower mortality in treated patients , but with a statistically significant reduction in only one trial . To overcome the problem of not being able to detect small but clinical ly important benefits in mortality in r and omized clinical trials of exercise and risk factor rehabilitation after myocardial infa rct ion with small numbers of patients , we carried out a meta- analysis on the combined results of ten r and omized clinical trials that included 4347 patients ( control , 2145 patients ; rehabilitation , 2202 patients ) . The pooled odds ratios of 0.76 ( 95 % confidence intervals , 0.63 to 0.92 ) for all-cause death and of 0.75 ( 95 % confidence intervals , 0.62 to 0.93 ) for cardiovascular death were significantly lower in the rehabilitation group than in the control group , with no significant difference for nonfatal recurrent myocardial infa rct ion . These results suggest that , for appropriately selected patients , comprehensive cardiac rehabilitation has a beneficial effect on mortality but not on nonfatal recurrent myocardial infa rct ion Health promotion programmes for patients with coronary heart disease are valuable,1 2 but there is little evidence on their lasting effect.3 A r and omised controlled trial in which patients who received personalised health promotion for two years showed significant benefits in lifestyle and quality of life.2 4 We investigated whether the differences in lifestyle , quality of life , and risk factors persisted between the two groups five years after enrolment . Patients aged under 75 who had had angina ( all grade s included ) for at least six months and no other concurrent serious illness were identified by 18 general practice s in Belfast . Their diagnosis was confirmed at interview , and they were r and omly allocated to receive either usual NHS care and personal health promotion from a trained nurse every four months for two years or usual NHS care alone . Sealed envelopes opened at interview showed group allocations . Both groups were review ed BACKGROUND Secondary prevention is not adequately implemented after myocardial infa rct ion ( MI ) . We assessed the effect on quality of care and prognosis of a long-term , relatively intensive rehabilitation strategy after MI . METHODS We conducted a multicenter , r and omized controlled trial in patients following st and ard post-MI cardiac rehabilitation  , comparing a long-term , reinforced , multifactorial educational and behavioral intervention with usual care . A total of 3241 patients with recent MI were r and omized to a 3-year multifactorial continued educational and behavioral program ( intervention group ; n = 1620 ) or usual care ( control group ; n = 1621 ) . The combination of cardiovascular ( CV ) mortality , nonfatal MI , nonfatal stroke , and hospitalization for angina pectoris , heart failure , or urgent revascularization procedure was the primary end point . Other end points were major CV events , major cardiac and cerebrovascular events , lifestyle habits , and drug prescriptions . RESULTS End point events occurred in 556 patients ( 17.2 % ) . Compared with usual care , the intensive intervention did not decrease the primary end point significantly ( 16.1 % vs 18.2 % ; hazard ratio [ HR ] , 0.88 ; 95 % confidence interval [ CI ] , 0.74 - 1.04 ) . However , the intensive intervention decreased several secondary end points : CV mortality plus nonfatal MI and stroke ( 3.2 % vs 4.8 % ; HR , 0.67 ; 95 % CI , 0.47 - 0.95 ) , cardiac death plus nonfatal myocardial infa rct ion ( 2.5 % vs 4.0 % ; HR , 0.64 ; 95 % CI , 0.43 - 0.94 ) , and nonfatal MI ( 1.4 % vs 2.7 % ; HR , 0.52 ; 95 % CI , 0.31 - 0.86 ) . A marked improvement in lifestyle habits ( ie , exercise , diet , psychosocial stress , less deterioration of body weight control ) and in prescription of drugs for secondary prevention was seen in the intervention group . CONCLUSION The GOSPEL Study is the first trial to our knowledge to demonstrate that a multifactorial , continued reinforced intervention up to 3 years after rehabilitation following MI is effective in decreasing the risk of several important CV outcomes , particularly nonfatal MI , although the overall effect is small . TRIAL REGISTRATION Clinical Trials.gov Identifier : NCT00421876 PURPOSE Despite demonstrated benefits of cardiac rehabilitation and risk factor reduction , only 11 % to 38 % of eligible patients with cardiovascular disease ( CVD ) participate in cardiac rehabilitation programs .  Women and older adults are particularly less likely to participate in cardiac rehabilitation . In an effort to broaden access to cardiac rehabilitation , the authors developed an alternative Internet-based program that allows nurse case managers to provide risk factor management training , risk factor education , and monitoring services to patients with CVD . METHODS The evaluation consisted of a r and omized , clinical trial involving 104 patients with CVD , 53 of whom used the program as a special intervention ( SI ) for 6 months and 51 of whom received usual care ( UC ) .  RESULTS The results indicate that fewer cardiovascular events occurred among the SI subjects ( 15.7 % ) than among the UC subjects ( 4.1 % ) ( P = .053 ) , result ing in a gross cost savings of $ 1418 US dollars per patient . With a projected program cost of $ 453 USD per patient , the return on investment is estimated at 213 % . More weight loss occurred in the SI group ( -3.68 pounds ) than in the UC group ( + .47 pounds ) ( P = .003 ) . The differences between the two groups in terms of blood pressure , lipid levels , depression scores , minutes of exercise , and dietary habits were not statistically significant . CONCLUSION An Internet-based case management system could be used as a cost-effective intervention for patients with CVD , either independently or in conjunction with traditional cardiac rehabilitation BACKGROUND Despite the large body of evidence confirming the effectiveness of lipid lowering for the secondary prevention of coronary heart disease ( CHD ) events , undertreatment of hyperlipidemia is common . This study tested the effectiveness of a nurse case management program to lower blood lipids in patients with CHD . METHODS A total of 228 consecutive , eligible adults with hypercholesterolemia and CHD were recruited during hospitalization after coronary revascularization . Patients were r and omized to receive lipid management , including individualized lifestyle modification and pharmacologic intervention , from a nurse practitioner for 1 year after discharge in addition to their usual care ( NURS ) , or to usual care enhanced with feedback on lipids to their primary provider and /or cardiologist ( EUC ) . RESULTS Significantly more patients in the NURS group than in the EUC group achieved low-density lipoprotein cholesterol ( LDL-C ) levels < 2.59 mmol/dL ( 100 mg/dL , 65 % vs 35 % , P = .0001 ) . Favorable changes in lipids and lipoproteins were accompanied by significant improvements in dietary and exercise patterns in the NURS group . In a multivariate analysis adjusting for other covariates , being assigned to the NURS group ( P = .0001 ) and being on a lipid-lowering medication ( P = .001 ) were significant independent predictors of LDL-C level . CONCLUSIONS Control of hypercholesterolemia in patients who have undergone coronary revascularization can be improved by a nurse case-management program . Because the National Cholesterol Education Program Adult Treatment Panel III guidelines have broadened the definition of high-risk population s that warrant aggressive treatment , nurse case-management programs may offer key opportunities to enhance appropriate application of new treatment paradigms Background Cardiac rehabilitation includes interventions aim ed at facilitating physical , psychological and emotional recovery following the acute phase of myocardial infa rct ion ( AMI ) . To date , optimal cardiac rehabilitation program duration and frequency of patient contact has yet to be identified . Objective The present study was performed to evaluate the effects of two different strategies of secondary prevention ( 2 years , multifactorial continued educational and behavioral intervention versus usual care ) implemented into a cardiac rehabilitation setting on several cardiovascular endpoints indicating cardiovascular functional exercise capacity and coronary risk profile in patients with recent AMI . Methods This was a prospect i ve r and omized study including 52 postinfa rct ion patients . Initially , all patients were enrolled in a 3-month outpatient cardiac rehabilitation program .  Thereafter , they were r and omly subdivided into two groups ( I = intervention group ; C = control group ) , each composed of 26 patients , and followed for 24 months . Results At the end of the 3-month outpatient cardiac rehabilitation program , both groups showed a significant ( P < 0.05 ) improvement in cardiopulmonary parameters ( maximal oxygen consumption , maximal workload ) and in cardiovascular risk profile ( BMI , lipid profile ) . During the 24-month study period , group I showed stabilization or even improvement ( P < 0.05 ) of both cardiopulmonary parameters and cardiovascular risk profile , whereas group C patients showed a deterioration or significant impairment ( P < 0.05 ) of the same parameters . Clinical events occurred in 27 % of patients in the control group ( n = 7 ) and in 11 % in the training group ( n = 3 ) ( P < 0.05 ) . Conclusion Long-term , multifactorial educational and behavioral intervention maintained for 2 years in a multicomprehensive cardiac rehabilitation setting represents a valid strategy for improving long-term cardiovascular functional capacity and cardiovascular risk profile in postinfa rct ion patients Background Lifestyle measures of coronary heart disease ( CHD ) prevention have been overshadowed by the efficacy of drug treatments . This is particularly the case in the setting of secondary prevention where the benefits of lipid lowering , anti-platelet and anti-hypertensive drugs have been emphasised in numerous trials . Lifestyle measures address several CHD risk factors at once and are generally free of serious side effects . Objectives The objective of the present study was to determine whether a comprehensive programme of lifestyle modification could favourably influence dietary and exercise habits in addition to smoking cessation over two years . In addition , an attempt was made to evaluate if this programme could favourably influence the five-year CHD-risk in the male population included in the study . Design A total of 197 patients with proven coronary heart disease were included and r and omised to a lifestyle intervention programme or to usual care . Follow-up was after a period of two years . Methods Intervention comprised a low fat diet , regular exercise , smoking cessation , psychosocial support and education , delivered by nurses on the rationale for pharmacological and lifestyle measures . Usual care comprised follow-up in the routine outpatient clinic . Both groups were given the same comprehensive medication according to recent guidelines . Results Patients in the lifestyle intervention group reduced the intake of saturated fat , sugar and cholesterol ( P<0.001 ) , increased their exercise level ( P<0.01 ) and stopped smoking ( P<0.05 ) when compared with the usual care group . A sub analysis of the influence of five-year CHD calculated risk in males result ed in a relative risk reduction of 22 % ( 95 % confidence intervals 9 - 35 ) . Although significant , this result must be interpreted with caution due to poor statistical power and reproducibility of the method . Conclusions In the presence of modern drug treatments for secondary cardiovascular disease prevention it remains possible through a favourable diet , exercise and smoking cessation to show an additional reduction in the five-year risk for CHD in males Abstract Objectives : To evaluate the effects of nurse led clinics in primary care on secondary prevention , total mortality , and coronary event rates after four years . Design : Follow up of a r and omised controlled trial by postal question naires and review of case notes and national data sets . Setting : Stratified , r and om sample of 19 general practice s in north east Scotl and . Participants : 1343 patients ( 673 intervention and 670 control ) under 80 years with a working diagnosis of coronary heart disease but without terminal illness or dementia and not housebound . Intervention : Nurse led secondary prevention clinics promoted medical and lifestyle components of secondary prevention and offered regular follow up for one year . Main outcome measures : Components of secondary prevention ( aspirin , blood pressure management , lipid management , healthy diet , exercise , non-smoking ) , total mortality , and coronary events ( non-fatal myocardial infa rct ions and coronary deaths ) . Results : Mean follow up was at 4.7 years . Significant improvements were shown in the intervention group in all components of secondary prevention except smoking at one year , and these were sustained after four years except for exercise . The control group , most of whom attended clinics after the initial year , caught up before final follow up , and differences between groups were no longer significant . At 4.7 years , 100 patients in the intervention group and 128 in the control group had died : cumulative death rates were 14.5 % and 18.9 % , respectively ( P=0.038 ) . 100 coronary events occurred in the intervention group and 125 in the control group : cumulative event rates were 14.2 % and 18.2 % , respectively ( P=0.052 ) . Adjusting for age , sex , general practice , and baseline secondary prevention , proportional hazard ratios were 0.75 for all deaths ( 95 % confidence intervals 0.58 to 0.98 ; P=0.036 ) and 0.76 for coronary events ( 0.58 to 1.00 ; P=0.049 ) Conclusions : Nurse led secondary prevention improved medical and lifestyle components of secondary prevention and this seemed to lead to significantly fewer total deaths and probably fewer coronary events .  Secondary prevention clinics should be started sooner rather than later . What is already known on this topic Several effective interventions exist for the secondary prevention of coronary heart disease , but implementing them in practice has proved difficult Secondary prevention programmes for coronary heart disease have improved short term outcomes such as processes of care and quality of life What this study adds Short term improvements in uptake of secondary prevention produced by nurse led clinics are maintained in the longer term Improved medical and lifestyle components of secondary prevention produced by nurse led clinics seem to lead to fewer total deaths and coronary In a prospect i ve , r and omised single-blinded secondary prevention trial we compared the effect of a Mediterranean alpha-linolenic acid-rich diet to the usual post-infa rct prudent diet .  After a first myocardial infa rct ion , patients were r and omly assigned to the experimental ( n = 302 ) or control group ( n = 303 ) . Patients were seen again 8 weeks after r and omisation , and each year for 5 years . The experimental group consumed significantly less lipids , saturated fat , cholesterol  , and  linoleic acid  but more  oleic  and  alpha-linolenic acids  confirmed by measurements in plasma . Serum lipids , blood pressure , and body mass index remained similar in the 2 groups . In the experimental group , plasma levels of albumin , vitamin E , and vitamin C were increased , and granulocyte count decreased . After a mean follow up of 27 months , there were 16 cardiac deaths in the control and 3 in the experimental group ; 17 non-fatal myocardial infa rct ion in the control and 5 in the experimental groups : a risk ratio for these two main endpoints combined of 0.27 ( 95 % CI 0.12 - 0.59 , p = 0.001 ) after adjustment for prognostic variables . Overall mortality was 20 in the control , 8 in the experimental group , an adjusted risk ratio of 0.30 ( 95 % CI 0.11 - 0.82 , p = 0.02 ) . An alpha-linolenic acid-rich Mediterranean diet seems to be more efficient than presently used diets in the secondary prevention of coronary events and death Background and aims : Coronary heart disease ( CHD ) is common and the maprity of CHD patients are 65 years or older . There exist only a few r and omized , controlled intervention studies on secondary prevention of CHD among elderly CHD patients . Our study assessed the effects of health advocacy , counseling , and activation programs with outcome variables of changes in the use of fats , lipid-lowering medications , frequency of exercise , cigarette smoking , serum cholesterol and triglyceride concentrations , blood pressure , and symptoms of late-life CHD among CHD patients of the Lieto Study . Methods : R and omized , controlled intervention study . Late-life ( > 65 yrs ) CHD patients were r and omized into intervention group ( IG ) ( n=118 ) and control group ( CG ) ( n=109 ) . Intervention consisted of 16 lectures by experts , eight group discussion s , six group exercise sessions , and three social activity events . Results : The use of lipid-lowering medications became more common in IG than in CG among men ( p=0.041 ) , with a similar tendency among women . Among women , decreases in the means of total serum cholesterol ( p=0.009 ) and LDL-cholesterol ( p=0.049 ) were greater in IG than in CG . Conclusions : The program produced no positive effects on health behavior . Positive effects were gained by the increase in lipid-lowering medications , which reduced mean total serum cholesterol and LDL-cholesterol concentrations . More intensive counseling on health behavior should be planned , implemented , and evaluated Objective : To determine the effect of a new CHOICE ( Choice of Health Options In prevention of Cardiovascular Events ) programme on cardiovascular risk factors in acute coronary syndrome ( ACS ) survivors . Design : Single-blind r and omised controlled trial . Setting : Tertiary referral hospital in Sydney Australia . Patients : 144 ACS survivors who were not accessing st and ard cardiac rehabilitation .  Data were also collected on a further 64 ACS survivors attending st and ard cardiac rehabilitation . Intervention : The CHOICE group ( n = 72 ) participated in a brief , patient-centred , modular programme comprising a clinic visit plus telephone support , encompassing m and atory cholesterol lowering and tailored preferential risk modification . The control group ( n = 72 ) participated in continuing conventional care but no central ly coordinated secondary prevention . Main outcome measures : Values for total cholesterol , systolic blood pressure , smoking status and physical activity . Results : CHOICE and control groups were well matched at baseline . At 12 months , the CHOICE group ( n = 67 ) had significantly better risk factor levels than controls ( n = 69 ) for total cholesterol ( TC ) ( mean ( SEM ) 4.0 ( 0.1 ) vs 4.7 ( 0.1 ) mmol/l , p<0.001 ) , systolic blood pressure ( 131.6 ( 1.8 ) vs 143.9 ( 2.3 ) mm Hg , p<0.001 ) , body mass index ( 28.9 ( 0.7 ) vs 31.2 ( 0.7 ) kg/m2 , p = 0.025 ) and physical activity ( 1369.1 ( 167.2 ) vs 715.1 ( 103.5 ) METS/kg/min , p = 0.001 ) as well as a better knowledge of risk factor targets . Also at 1 year , fewer CHOICE participants ( 21 % ) had three or more risk factors above widely recommended levels then controls ( 72 % ) ( p<0.001 ) . Conclusions : Participation in a brief CHOICE programme significantly improved the modifiable risk profiles and risk factor knowledge of ACS survivors over 12 months . CHOICE is an effective alternative for dealing with the widespread underuse of existing secondary prevention programmes . Trial registration number : IS RCT
target: The overall results for modifiable risk factors suggested improvements in dietary and exercise outcomes but no overall effect on smoking outcomes .
background: The effectiveness of lifestyle interventions within secondary prevention of coronary heart disease ( CHD ) remains unclear .
  This systematic review aim ed to determine their effectiveness and included r and omized controlled trials of lifestyle interventions , in primary care or community setting s , with a minimum follow-up of three months , published since 1990 .
