Statins have been proved to be effective in reduction of mortality and morbidity when started in the early secondary prevention in stabilized patients after acute coronary syndrome (ACS). The safety and efficacy of statin administration directly in the first-line therapy in unstable ACS patients is not clear. The aim of our study was, therefore, to assess the effect of statin treatment initiated immediately at hospital admission of patients with ACS.
                The trial was stopped prematurely after enrollment of one hundred and fifty-six patients with ACS that were randomized at admission to fluvastatin 80 mg (N = 78) or placebo (N = 78). Study medication was administered immediately after randomization and then once daily for 30 days; all patients were then encouraged to continue in open-label statin therapy and at the end of one-year follow-up 75% in the fluvastatin group and 78% in the placebo group were on statin therapy.
                We did not demonstrate any difference between groups in the level of C-reactive protein, interleukin 6, and pregnancy-associated plasma protein A on Day 2 and Day 30 (primary endpoint). Fluvastatin-therapy, however, significantly reduced one-year occurrence of major adverse cardiovascular events (11.5% vs. 24.4%, odds ratio (OR) 0.40, 95% CI 0.17-0.95, P = 0.038). This difference was caused mainly by reduction of recurrent symptomatic ischemia (7.7% vs. 20.5%, OR 0.32, 95% CI 0.12-0.88, P = 0.037).
                This study failed to prove the effect of fluvastatin given as first-line therapy of ACS on serum markers of inflammation and plaque instability. Fluvastatin therapy was, however, safe and it may reduce cardiovascular event rate that supports immediate use of a statin in patients admitted for ACS.
                NCT00171275. Secondary prevention of coronary heart disease by antilipidemic therapy beginning at > or =3 months after an acute coronary syndrome is well documented. The impact, however, of immediate initiation of antilipidemic therapy on coronary stenoses and clinical outcome in patients with acute coronary syndrome is unknown. In our study, patients were randomized, on average, 6 days after an acute myocardial infarction and/or percutaneous transluminal coronary angioplasty secondary to unstable angina, to pravastatin (combined, when necessary, with cholestyramine and/or nicotinic acid) to achieve low-density lipoprotein cholesterol levels of < or =130 mg/dl (group A, n = 70). In controls (group B, n = 56), antilipidemic therapy was determined by family physicians. Quantitative coronary angiography was performed at inclusion, and at 6- and 24-month follow-up. The combined clinical end points were total mortality, cardiovascular death, nonfatal myocardial infarction, need for coronary intervention, stroke, and new onset of peripheral vascular disease. Minimal lumen diameter in group A increased by 0.05 +/- 0.20 mm after 6 months and 0.13 +/- 0.29 mm after 24 months, whereas it decreased by 0.08 +/- 0.20 mm and 0.18 +/- 0.27 mm, respectively, in group B (p = 0.004 at 6 months and p <0.001 at 24 months). After 2 years, 29 patients of 56 patients in group B, but only 16 of 70 patients in group A, experienced a clinical end point (p = 0.005; odds ratio 0.28, confidence intervals 0.13 to 0.6). We conclude that pravastatin-based therapy initiated immediately after an acute coronary syndrome is well tolerated and safe, lessens coronary atherosclerosis, and has a pronounced clinical benefit. The efficacy of statin drugs after an acute coronary event is now well established, but the evidence for statin use in the early treatment of acute coronary events remains unclear.
                We tested the effects of administering pravastatin within 24 hours of the onset of symptoms in patients with unstable angina, non-ST-segment elevation myocardial infarction, or ST-segment elevation myocardial infarction. Patient recruitment of 10,000 with 1200 end points was planned, but the trial was stopped early. A total of 3408 patients were randomly assigned to treatment with pravastatin (1710 patients) or matching placebo (1698 patients). Treatment was continued for 4 weeks. The primary end point of the study was a composite of death, recurrence of myocardial infarction, or readmission to hospital for unstable angina within 30 days of random assignment.
                The primary end point occurred in 199 of patients allocated to pravastatin (11.6%) and in 211 patients allocated to placebo (12.4%). A relative risk reduction of 6.4% favored allocation to pravastatin but was not statistically significant (95% CI, -13.2% to 27.6%). No adverse effects were seen.
                We conclude that 20 to 40 mg of pravastatin can be safely administered within 24 hours of the onset of symptoms of an acute coronary event, with a favorable but not significant trend in outcome at 30 days compared with placebo. In spite of a large number of studies on the use of HMG-CoA-reductase inhibitors (statins) in treatment of different forms of coronary artery disease, the efficacy of their early administration in acute coronary syndrome (ACS) is still unclear. The purpose of the present investigation was to study the effects of medium doses (40 mg per day) of simvastatin on the clinical course of ACS and blood levels of C-reactive protein (CRP) and lipids in ACS patients to whom the drug was administered on the first day of the disease. One hundred and eight patients with ACS were randomized into two groups: the control group receiving standard therapy, and the main group receiving in addition 40 mg of simvastatin beginning on the first day of the disease. Blood levels of lipids and CRP were measured by a precise qualitative technique on the first and fourteenth days of the disease. The clinical course of the disease was evaluated during six months from the first day of hospital stay. Mean CRP level decreased significantly within two weeks in the group of patients receiving simvastatin (from 14.9 +/- 9.7 to 7.6 +/- 6.0 mg/l; p = 0.02). In the control group CRP concentration decreased less and not significantly (from 16.1 +/- 7.3 to 13.2 +/- 6.8 mg/l; p = 0.18). Two main types of the dynamics of CRP level were revealed in the ACS patients. Most patients in both groups displayed a decrease in CRP level by the fourteenth day of the disease. At the same time, in some patients CRP level grew during this period, and these patients had stenocardia and required repeated hospital admissions due to ACS recurrence significantly more frequently during the following six months (relative risk 1.4; 95% confidence interval 1.1 to 1.8). The frequency of postinfarction stenocardia was the most substantial and significant clinical difference between the groups (50.9% in the control group, and 23.6% in the main group, p = 0.04). Thus, early therapy with simvastatin in ACS lowers SRP level and the frequency of postinfarction stenocardia. The elevation of CRP level during the first two weeks of the disease is a poor prognostic sign. Clinical trials have demonstrated that, compared with placebo, intensive statin therapy reduces ischemia in patients with acute coronary syndromes and in patients with stable coronary artery disease. However, no studies to date have assessed intensive versus moderate statin therapy in older patients with stable coronary syndromes.
                A total of 893 ambulatory coronary artery disease patients (30% women) 65 to 85 years of age with > or = 1 episode of myocardial ischemia that lasted > or = 3 minutes during 48-hour ambulatory ECG at screening were randomized to atorvastatin 80 mg/d or pravastatin 40 mg/d and followed up for 12 months. The primary efficacy parameter (absolute change from baseline in total duration of ischemia at month 12) was significantly reduced in both groups at month 3 and month 12 (both P<0.001 for each treatment group) with no significant difference between the treatment groups. Atorvastatin-treated patients experienced greater low-density lipoprotein cholesterol reductions than did pravastatin-treated patients, a trend toward fewer major acute cardiovascular events (hazard ratio, 0.71; 95% confidence interval, 0.46, 1.09; P=0.114), and a significantly greater reduction in all-cause death (hazard ratio, 0.33; 95% confidence interval, 0.13, 0.83; P=0.014).
                Compared with moderate pravastatin therapy, intensive atorvastatin therapy was associated with reductions in cholesterol, major acute cardiovascular events, and death in addition to the reductions in ischemia observed with both therapies. The contrast between the therapies' differing efficacy for major acute cardiovascular events and death and their nonsignificant difference in efficacy for reduction of ischemia suggests that low-density lipoprotein cholesterol-lowering thresholds for ischemia and major acute cardiovascular events may differ. The Study Assessing Goals in the Elderly (SAGE) demonstrates that older men and women with coronary artery disease benefit from intensive statin therapy. Statins have been shown to prevent coronary artery disease and to preserve left ventricular function in dilated cardiomyopathy. We hypothesized that early use of statins would decrease cardiovascular events, including heart failure in patients with acute myocardial infarction (AMI). To examine the effect of statins in Japanese patients with AMI, a prospective, randomized, open-label trial was conducted in 486 patients with normal total cholesterol levels. Patients were randomly assigned to receive any available statin (n = 241) within 96 hours of AMI onset or no statin (n = 245) and were followed for up to 24 months. The primary end point was a composite of cardiovascular death, nonfatal AMI, recurrent symptomatic myocardial ischemia, congestive heart failure, and stroke. Event rate for the primary end point was lower in the statin group than in the nonstatin group (6.1% vs 11.4%, p = 0.0433). The statin group had a lower risk of congestive heart failure and symptomatic myocardial ischemia (p = 0.0154 and 0.0264, respectively). In conclusion, early lipid-lowering therapy with statins decreases recurrent cardiovascular events, in particular, congestive heart failure. Patients experience the highest rate of death and recurrent ischemic events during the early period after an acute coronary syndrome, but it is not known whether early initiation of treatment with a statin can reduce the occurrence of these early events.
                To determine whether treatment with atorvastatin, 80 mg/d, initiated 24 to 96 hours after an acute coronary syndrome, reduces death and nonfatal ischemic events.
                A randomized, double-blind trial conducted from May 1997 to September 1999, with follow-up through 16 weeks at 122 clinical centers in Europe, North America, South Africa, and Australasia.
                A total of 3086 adults aged 18 years or older with unstable angina or non-Q-wave acute myocardial infarction.
                Patients were stratified by center and randomly assigned to receive treatment with atorvastatin (80 mg/d) or matching placebo between 24 and 96 hours after hospital admission.
                Primary end point event defined as death, nonfatal acute myocardial infarction, cardiac arrest with resuscitation, or recurrent symptomatic myocardial ischemia with objective evidence and requiring emergency rehospitalization.
                A primary end point event occurred in 228 patients (14.8%) in the atorvastatin group and 269 patients (17.4%) in the placebo group (relative risk [RR], 0.84; 95% confidence interval [CI], 0.70-1.00; P =.048). There were no significant differences in risk of death, nonfatal myocardial infarction, or cardiac arrest between the atorvastatin group and the placebo group, although the atorvastatin group had a lower risk of symptomatic ischemia with objective evidence and requiring emergency rehospitalization (6.2% vs 8.4%; RR, 0.74; 95% CI, 0.57-0.95; P =.02). Likewise, there were no significant differences between the atorvastatin group and the placebo group in the incidence of secondary outcomes of coronary revascularization procedures, worsening heart failure, or worsening angina, although there were fewer strokes in the atorvastatin group than in the placebo group (12 vs 24 events; P =.045). In the atorvastatin group, mean low-density lipoprotein cholesterol level declined from 124 mg/dL (3.2 mmol/L) to 72 mg/dL (1.9 mmol/L). Abnormal liver transaminases (>3 times upper limit of normal) were more common in the atorvastatin group than in the placebo group (2.5% vs 0.6%; P<.001).
                For patients with acute coronary syndrome, lipid-lowering therapy with atorvastatin, 80 mg/d, reduces recurrent ischemic events in the first 16 weeks, mostly recurrent symptomatic ischemia requiring rehospitalization. To compare the use of lipid-lowering agents in 42 628 elderly patients (aged > or =65 years) after acute myocardial infarction, before and after the publication of the Scandinavian Simvastatin Survival Study (4S), using the Ontario Myocardial Infarction Database.
                Multivariate regression models were created to estimate changes in the rate of statin use over time in monthly cohorts of elderly patients after acute myocardial infarction in Ontario from April 1, 1992, to March 31, 1997. Changes in the rate of statin use over time were estimated using patient and prescriber characteristics.
                We found a 3.6-fold significant increase in the monthly rate of statin use after the publication of 4S compared with before the publication of 4S (P<.001); specifically, the rate of increase in simvastatin and pravastatin sodium use was higher after the publication of 4S (P<.001 for each). Before the publication of 4S, the rate of increase in statin use in younger patients (aged 65-74 years) was 2.7 times higher than in older patients (aged > or =75 years) (P =.02), while after the publication of 4S, the rate of increase in statin use was only 1.8-fold higher in the younger group (P<.001). After the publication of 4S, there was a 1.6-fold higher rate of increase in statin use in male compared with female patients (P =.006). Also after the publication of 4S, specialists (cardiologists and internists) had a 2-fold higher rate of increased use of the statins than did generalists (P<.001).
                It is possible to shift practice if the evidence of benefit is strong, the intervention is easy to implement, and the intervention is marketed aggressively. Percutaneous coronary intervention (PCI) is associated with excellent short-term improvements in ischemic symptoms, yet only three fifths of PCI patients at 5 years and one third of patients at 10 years remain free of major adverse cardiac events (MACE).
                To determine whether treatment with fluvastatin reduces MACE in patients who have undergone PCI.
                Randomized, double-blind, placebo-controlled trial conducted at 77 referral centers in Europe, Canada, and Brazil.
                A total of 1677 patients (aged 18-80 years) recruited between April 1996 and October 1998 with stable or unstable angina or silent ischemia following successful completion of their first PCI who had baseline total cholesterol levels between 135 and 270 mg/dL (3.5-7.0 mmol/L), with fasting triglyceride levels of less than 400 mg/dL (4.5 mmol/L).
                Patients were randomly assigned to receive treatment with fluvastatin, 80 mg/d (n = 844), or matching placebo (n = 833) at hospital discharge for 3 to 4 years.
                Survival time free of MACE, defined as cardiac death, nonfatal myocardial infarction, or reintervention procedure, compared between the treatment and placebo groups.
                Median time between PCI and first dose of study medication was 2.0 days, and median follow-up was 3.9 years. MACE-free survival time was significantly longer in the fluvastatin group (P =.01). One hundred eighty-one (21.4%) of 844 patients in the fluvastatin group and 222 (26.7%) of 833 patients in the placebo group had at least 1 MACE (relative risk [RR], 0.78; 95% confidence interval [CI], 0.64-0.95; P =.01). This result was independent of baseline total cholesterol levels (above [RR, 0.76; 95% CI, 0.56-1.04] vs below [RR, 0.77; 95% CI, 0.57-1.02] the median). In subgroup analysis, the risk of MACE was reduced in patients with diabetes (n = 202; RR, 0.53; 95% CI, 0.29-0.97; P =.04) and in those with multivessel disease (n = 614; RR, 0.66; 95% CI, 0.48-0.91; P =.01) who received fluvastatin compared with those who received placebo. There were no instances of creatine phosphokinase elevations 10 or more times the upper limit of normal or rhabdomyolysis in the fluvastatin group.
                Fluvastatin treatment in patients with average cholesterol levels undergoing their first successful PCI significantly reduces the risk of major adverse cardiac events. Recent clinical trials have demonstrated that aggressive lipid lowering by statins could prevent recurrent events after acute coronary syndrome (ACS). We hypothesized that this efficacy was caused by a significant reduction in plaque volume by aggressive LDL cholesterol (LCL-C) lowering. The present study investigated the effect of early statin treatment on plaque volume of a nonculprit lesion by serial volumetric intravascular ultrasound in patients with ACS.
                Seventy patients with ACS were enrolled. All patients underwent emergency coronary angiography and percutaneous coronary intervention (PCI). They were randomized to intensive lipid-lowering therapy (n=35; atorvastatin 20 mg/d) or control (n=35) groups after PCI. Volumetric intravascular ultrasound analyses were performed at baseline and 6-month follow-up for a non-PCI site in 48 patients (atorvastatin, n=24; control, n=24). LDL-C level was significantly decreased by 41.7% in the atorvastatin group compared with the control group, in which LDL-C was increased by 0.7% (P<0.0001). Plaque volume was significantly reduced in the atorvastatin group (13.1+/-12.8% decrease) compared with the control group (8.7+/-14.9% increase; P<0.0001). Percent change in plaque volume showed a significant positive correlation with follow-up LDL-C level (R=0.456, P=0.0011) and percent LDL-C reduction (R=0.612, P<0.0001), even in patients with baseline LDL-C <125 mg/dL.
                Early aggressive lipid-lowering therapy by atorvastatin for 6 months significantly reduced the plaque volume in patients with ACS. Percent change in plaque volume showed a significant positive correlation with percent LDL-C reduction, even in patients with low baseline LDL-C. Proven efficacious therapies are sometimes underused in patients with chronic cardiac conditions, resulting in suboptimal outcomes. We evaluated whether evidence summaries, which were either unsigned or signed by local opinion leaders, improved the quality of secondary prevention care delivered by primary care physicians of patients with coronary artery disease.
                We performed a randomized trial, clustered at the level of the primary care physician, with 3 study arms: control, unsigned statements or opinion leader statements. The statements were faxed to primary care physicians of adults with coronary artery disease at the time of elective cardiac catheterization. The primary outcome was improvement in statin management (initiation or dose increase) 6 months after catheterization.
                We enrolled 480 adults from 252 practices. Although statin use was high at baseline (n=316 [66%]), most patients were taking a low dose (mean 32% of the guideline-recommended dose), and their low-density lipoprotein (LDL) cholesterol levels were elevated (mean 3.09 mmol/L). Six months after catheterization, statin management had improved in 79 of 157 patients (50%) in the control arm, 85 of 158 (54%) patients in the unsigned statement group (adjusted odds ratio [OR] 1.18, 95% CI 0.71-1.94, p=0.52) and 99 of 165 (60%) patients in the opinion leader statement group (adjusted OR 1.51, 95% CI 0.94-2.42, p=0.09). The mean fasting LDL cholesterol levels after 6 months were similar in all 3 study arms: 2.35 (standard deviation [SD] 0.86) mmol/L in the control arm compared with 2.24 (SD 0.73) among those in the opinion leader group (p=0.48) and 2.19 (SD 0.68) in the unsigned statement group (p=0.32).
                Faxed evidence reminders for primary care physicians, even when endorsed by local opinion leaders, were insufficient to optimize the quality of care for adults with coronary artery disease. ClinicalTrials.gov trial register no. NCT00175240. Therapy with individual 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) has been shown conclusively to diminish coronary event rates and mortality in both primary and secondary prevention. To date, scant attention has been paid to whether initiation of such regimens in the hospital phase of acute coronary syndromes might confer cardioprotective benefits. The purpose of this study was to determine the safety and tolerability of early initiation of statin therapy in patients with acute coronary syndromes. In this randomised, double-blind, three-month, pilot study, 100 patients with acute myocardial infarction or unstable angina and low-density lipoprotein cholesterol > 3.5 mmol/l were randomly assigned to pravastatin 40 mg daily or placebo initiated within 48 hours of hospital admission. Pravastatin proved safe and well tolerated in these patients, who were well matched at baseline. No statistically significant differences in death, MI and drug-related adverse events were observed in the pravastatin group compared with control subjects. This pilot study shows that therapy with pravastatin early after an acute coronary event is safe and well tolerated. Larger, long-term studies are needed to confirm these findings. This prospective, randomized, placebo-controlled, double-blind clinical trial was performed to analyze the effect of atorvastatin compared with placebo on the occurrence of a 6-month composite of cardiovascular events after vascular surgery. Cardiovascular complications are the most important cause of perioperative morbidity and mortality among patients undergoing vascular surgery. Statin therapy may reduce perioperative cardiac events through stabilization of coronary plaques.
                One hundred patients were randomly assigned to receive 20 mg atorvastatin or placebo once a day for 45 days, irrespective of their serum cholesterol concentration. Vascular surgery was performed on average 30 days after randomization, and patients were prospectively followed up over 6 months. The cardiovascular events studied were death from cardiac cause, nonfatal myocardial infarction, unstable angina, and stroke.
                Fifty patients received atorvastatin, and 50 received placebo. During the 6-month follow-up primary end points occurred in 17 patients, 4 in the atorvastatin group and 13 in the placebo group. The incidence of cardiac events was more than three times higher with placebo (26.0%) compared with atorvastatin (8.0%; P =.031). The risk for an event was compared between the groups with the Kaplan-Meier method, as event-free survival after vascular surgery. Patients given atorvastatin exhibited a significant decrease in the rate of cardiac events, compared with the placebo group, within 6 months after vascular surgery (P =.018).
                Short-term treatment with atorvastatin significantly reduces the incidence of major adverse cardiovascular events after vascular surgery. In a double-blind, placebo-controlled trial, 225 patients with acute partial stable thrombotic stroke were randomly assigned to receive continuous intravenous heparin therapy or placebo for 7 days for the prevention of stroke progression or death. No statistically significant difference between the two groups was found in degree of neurologic change; incidence of stroke progression after 7 days; or functional activity level of survivors at 7 days, 3 months and at 1 year after treatment. Compared with controls, a statistically significant greater number of patients in the group receiving heparin died in the year after the stroke. These deaths occurred 3 to 12 months after the initial stroke and probably were not related to treatment. Results of this study do not support the use of intravenous heparin to treat patients who have had acute partial stroke. To determine whether statin therapy initiated early in acute myocardial infarction together with thrombolytic therapy in patients with acute myocardial infarction results in clinical benefit through early plaque stabilization.
                The study population consisted of 77 patients who underwent coronary balloon angioplasty of the infarct-related artery during the first month of acute myocardial infarction. These patients belonged to the cohort of the Pravastatin Turkish Trial (PTT). Forty of them were assigned randomly to have immediate pravastatin (40 mg/day) therapy adjunctive to thrombolytic therapy regardless of serum lipid levels and received statin treatment throughout the study. Lipid levels were determined immediately after admission and before angioplasty and at the end of 6 months. Patients were re-evaluated clinically and angiographically for cardiovascular adverse events and restenosis after a 6-month follow-up period. The baseline angiographic and clinical characteristics of the two groups were similar. The incidence of angina was significantly lower in the pravastatin group (30.0%, 12 patients) compared to the control group (59.5%, 22 patients) (p = 0.018). The cumulative major adverse cardiac events in the pravastatin group were significantly lower when compared to the control group (32.5% vs. 75.6%, p = 0.0001).
                Early initiation of pravastatin therapy immediately after an acute myocardial infarction significantly decreased the frequency of major cardiac adverse events. Such early potential clinical benefits further strengthen the rationale for starting statin treatment as soon as possible after acute coronary events particularly in patients in whom invasive intervention is planned. Atrial fibrillation (AF) after cardiac surgery is associated with increased risk of complications, length of stay, and cost of care. Observational evidence suggests that patients who have undergone previous statin therapy have a lower incidence of postoperative AF. We tested this observation in a randomized, controlled trial.
                Two hundred patients undergoing elective cardiac surgery with cardiopulmonary bypass, without previous statin treatment or history of AF, were enrolled. Patients were randomized to atorvastatin (40 mg/d, n=101) or placebo (n=99) starting 7 days before operation. The primary end point was incidence of postoperative AF; secondary end points were length of stay, 30-day major adverse cardiac and cerebrovascular events, and postoperative C-reactive protein (CRP) variations. Atorvastatin significantly reduced the incidence of AF versus placebo (35% versus 57%, P=0.003). Accordingly, length of stay was longer in the placebo versus atorvastatin arm (6.9+/-1.4 versus 6.3+/-1.2 days, P=0.001). Peak CRP levels were lower in patients without AF (P=0.01), irrespective of randomization assignment. Multivariable analysis showed that atorvastatin treatment conferred a 61% reduction in risk of AF (odds ratio 0.39, 95% confidence interval 0.18 to 0.85, P=0.017), whereas high postoperative CRP levels were associated with increased risk (odds ratio 2.0, 95% confidence interval 1.2 to 7.0, P=0.01). The incidence of major adverse cardiac and cerebrovascular events at 30 days was similar in the 2 arms.
                Treatment with atorvastatin 40 mg/d, initiated 7 days before surgery, significantly reduces the incidence of postoperative AF after elective cardiac surgery with cardiopulmonary bypass and shortens hospital stay. These results may influence practice patterns with regard to adjuvant pharmacological therapy before cardiac surgery. Four hundred seventy-seven patients suspected of having had acute myocardial infarction within less than 12 hours were randomized to receive i.v. atenolol followed by oral treatment for 10 days or to a control group. In patients with ECG changes indicative of infarction at entry, i.v. atenolol significantly reduced enzyme release by one-third and enhanced R-wave preservation. In patients without such ECG changes, treatment significantly prevented the development of infarction in a proportion of patients. There was also a significant reduction in R-on-T ectopics, repetitive ventricular arrhythmias and supraventricular arrhythmias. Treated patients had significantly greater pain relief and required fewer opiate analgesics. Significantly fewer atenolol-treated patients died by 10 days (the treatment period), had nonfatal cardiac arrests, developed heart failure, or suffered reinfarction.
Based on available evidence, initiation of statin therapy within 14 days following ACS does not reduce death, myocardial infarction, or stroke up to four months, but reduces the occurrence of unstable angina at four months following ACS.
