The Myocardial Ischemia Reduction with Acute Cholesterol Lowering trial: MIRACuLous or not,it's time to change current practice

The Myocardial Ischemia Reduction with Aggressive Cholesterol Lowering (MIRACL) study was the first trial to assess whether statins might be of clinical benefit in those with recently unstable coronary disease. MIRACL found that high-dose atorvastatin was safe and reduced the incidence of the composite endpoint, death, non-fatal myocardial infarction, resuscitated sudden cardiac death or emergent rehospitalization for recurrent ischemia at 16 weeks when compared with placebo. Despite a number of important study limitations, MIRACL's findings and the prior observation that inpatient initiation of lipid-lowering therapy is associated with higher rates of subsequent utilization, suggest that it is prudent to begin statin therapy when patients present with an acute coronary syndrome.     

The Myocardial Ischemia Reduction with Acute Cholesterol Lowering (MIRACL) trial: a new frontier for statins?

The Myocardial Ischemia Reduction with Acute Cholesterol Lowering (MIRACL) Trial tested the hypothesis that intensive lowering of cholesterol with atorvastatin (80 mg/day) initiated 24-96 h after an acute coronary syndrome would, over 4 months, reduce the incidence of the composite endpoint of death, nonfatal infarction, resuscitated cardiac arrest, and recurrent symptomatic myocardial ischemia with new objective symptoms requiring emergency rehospitalization. This primary composite endpoint was reduced from 17.4% to 14.8% (P = 0.048) among the 3086 patients enrolled. The results of MIRACL suggest that patients with acute coronary syndromes should begin to receive this treatment before leaving hospital, irrespective of baseline levels of low-density lipoprotein-cholesterol.     

Intensive statin therapy in acute coronary syndromes: clinical benefits and vascular biology

PURPOSE OF REVIEW: The results of a landmark clinical study comparing intensive statin therapy with conventional statin therapy, in patients with acute coronary syndromes (ACS), are reviewed. The mechanisms behind these results are analysed drawing data from vascular and cell biology. RECENT FINDINGS: The Pravastatin or Atorvastatin Evaluation and Infection Therapy-Thrombolysis in Myocardial Infarction (PROVE IT-TIMI 22) study showed that intensive statin therapy with 80 mg of atorvastatin to achieve a low-density lipoprotein cholesterol of 62 mg/dl resulted in a 3.9% absolute and a 16% relative risk reduction in death or major cardiovascular events up to 2 years, compared to 40 mg of pravastatin, in patients with ACS. The results were especially significant as intensive statin therapy resulted in a very early benefit (<30 days) and occurred against a background of percutaneous coronary intervention (69%) for the index admission and high use of medications for secondary prevention. The PROVE IT and the Myocardial Ischaemia Reduction with Aggressive Cholesterol Lowering (MIRACL) C-reactive protein sub-study also showed that atorvastatin (80 mg) resulted in a significant reduction in markers of inflammation, whilst the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) study showed that intensive statin therapy was associated with reduced progression of atherosclerosis compared with conventional doses of statins. SUMMARY: Intensive statin therapy results in a significant early reduction in adverse cardiac events in ACS patients which are sustained over 2 years. The early benefits seen are likely to result from modulation of inflammation, endothelial function and coagulation, i.e. the pleiotropic effects, whereas the greater reduction in low-density lipoprotein cholesterol results in reduced long-term events.     

Lipid management after acute coronary syndrome

PURPOSE OF REVIEW: Despite advances in medical therapy and percutaneous revascularization, patients with acute coronary syndrome face a high risk of early, recurrent cardiovascular events. Interventions targeting atherogenic lipoproteins may favorably modify this risk. RECENT FINDINGS: Two randomized clinical trials, MIRACL and PROVE-IT, demonstrated efficacy of early, intensive statin therapy after acute coronary syndrome. Recent observational and meta-analyses corroborate the findings of these trials. The benefit of intensive statin treatment appears to apply broadly to elderly as well as younger patients, and to patients with or without diabetes or metabolic syndrome. Randomized trials demonstrating the efficacy of early, intensive statin treatment after acute coronary syndrome employed fixed statin dosages, and there does not appear to be an initial or achieved LDL-cholesterol level below which benefit is absent. As such, broad application of intensive statin therapy after acute coronary syndrome may be preferable to titration of statin dose to achieve specific LDL goals. Low HDL-cholesterol predicts risk after acute coronary syndrome; therefore, pharmacologic interventions to raise HDL concentration or mimic its function may help reduce that risk. SUMMARY: Early, intensive statin therapy is safe and effective after acute coronary syndrome. Future research will determine whether drugs that raise or mimic HDL-cholesterol are effective adjuncts to statin therapy.     

Revascularization in the acute coronary syndromes

Coronary heart disease is the leading cause of death worldwide, and occurs when the coronary arteries are unable to supply adequate oxygenated blood to the myocardium, which in turn can lead to ischemia and infarction of myocardial tissue. There are three options for revascularization in the setting of acute coronary syndromes. In select patients, coronary artery bypass surgery remains an option. Thrombolytics were initially the mainstay of therapy, which has now shifted to angioplasty, with or without stents, when readily available. Revascularization has been demonstrated to improve patient outcomes, and has evolved rapidly in the recent past.     

Antithrombotic therapy

Coronary heart disease is the leading cause of death in the US and the industrialized world. Ever since DeWood in 1980 demonstrated that a thrombus was the primary event leading to acute myocardial infarction and that they may subsequently lyse, the mainstay of therapy for the past 25 years has been antithrombotic therapy aimed at coronary thrombosis. There have been numerous advances in the treatment of acute coronary syndrome with antiplatelet, antithrombotic, and fibrinolytic agents that have significantly reduced morbidity and mortality. The role of various pharmaceutical agents in the different phases of acute coronary syndrome is a complex and ever changing field.7.     

Relation of low diastolic blood pressure to coronary heart disease death in presence of myocardial infarction: the Framingham Study.

OBJECTIVE--To examine the hypothesis that a J curve relation between blood pressure and death from coronary heart disease is confined to high risk subjects with myocardial infarction. DESIGN--Cohort longitudinal epidemiological study with biennial examinations since 1950. SETTING--Framingham, Massachusetts, USA. SUBJECTS--5209 subjects in the Framingham study cohort followed up by a person examination approach. MAIN OUTCOME MEASURES--Coronary heart disease deaths and non-cardiovascular disease deaths in men and women with or without myocardial infarction relative to blood pressure. RESULTS--Among subjects without myocardial infarction non-cardiovascular disease deaths were twice to three times as common as coronary heart disease deaths. Furthermore, there was no significant relation between non-cardiovascular disease death and diastolic or systolic blood pressure. Also coronary heart disease deaths were linearly related to diastolic and systolic blood pressures. Among high risk patients (that is, people with myocardial infarction but free of congestive heart failure) death from coronary heart disease was more common than non-cardiovascular disease death. There was a significant U shaped relation between coronary heart disease death and diastolic blood pressure. Although there was an apparent U shaped relation between coronary heart disease death and systolic blood pressure, it did not attain statistical significance when controlling for age and change in systolic blood pressure from the pre-myocardial infarction level. None of the above conclusions changed when adjustments were made for risk factors such as serum cholesterol concentration, antihypertensive treatment, and left ventricular function. The U shaped relation between diastolic blood pressure and high risk subjects existed for both those given antihypertensive treatment and those not. CONCLUSIONS--These data suggest that an age and sex independent U curve relation exists for diastolic blood pressure and coronary heart disease deaths in patients with myocardial infarction but not for low risk subjects without myocardial infarction. The relation seems to be independent of left ventricular function and antihypertensive treatment.     

Evidence-based management of coronary artery disease in the elderly--current perspectives

Cardiovascular disease accounts for significant morbidity and mortality in the elderly. The clinical trial data available to guide therapy in this growing population subset are relatively limited. This review will focus on treatment approaches and recommendations obtained from subgroup analyses of elderly patients from major clinical trials for the management of chronic stable angina, acute coronary syndromes (unstable angina and non-ST-segment elevation myocardial infarction), and coronary revascularization. Recent advances in the treatment of stable angina have shown that use of angiotensin-converting enzyme inhibitors and lipid-lowering therapy as adjunctive measures show benefit in the elderly by reducing the occurrence of death, nonfatal myocardial infarction, and unstable angina. However, if patients experience disabling or unstable anginal symptoms despite effective medical therapy, coronary revascularization must be considered. Several clinical trials have shown a significant reduction in major adverse cardiac events when using intravenous glycoprotein receptor antagonists periprocedurally during percutaneous revascularization approaches in elderly patients with unstable angina or non-ST-segment elevation myocardial infarction, especially when these measures are performed as soon as possible. However, the success of myocardial revascularization by a percutaneous or surgical approach is highly dependent on the patient's associated comorbidities, especially in patients over age 80 years.     

Evidence-based management of acute myocardial infarction in the elderly--current perspectives

Cardiovascular disease accounts for significant morbidity and mortality in the elderly. Despite several, large cardiovascular clinical trials, data to guide therapy in this growing population subset are relatively limited. This review focuses on treatment approaches and recommendations for the management of elderly patients with acute myocardial infarction (MI) obtained from subgroup analyses from major clinical trials.Treatment options for acute MI in the elderly have changed dramatically since the 1990s. Reperfusion therapy by primary percutaneous coronary intervention has superseded the use of thrombolytic therapy for the treatment of acute ST-elevation myocardial infarction (STEMI). Clinical trial data have demonstrated that even transferring patients to facilities that have primary angioplasty capabilities is better than thrombolytic therapy, if the anticipated transfer time is of acceptable duration. Additionally, adjunctive use of the intravenous glycoprotein (GP) receptor antagonist, abciximab, during primary angioplasty affords a reduction in the composite primary end point of death, reinfarction, and target vessel revascularization, with much of the benefit derived from the latter. Thrombolytic therapy, barring any contraindication, must be used when mechanical revascularization is not available; however, the risk for complications in the elderly is higher, especially for those 75 years and older. Studies investigating the use of thrombolytics plus GP receptor antagonists with and without percutaneous coronary intervention show questionable benefit in the elderly.     

Does plasma cholesterol concentration predict mortality from coronary heart disease in elderly people? 18 year follow up in Whitehall study.

OBJECTIVE--To explore the extent to which the relation between plasma cholesterol concentration and risk of death from coronary heart disease in men persists into old age. DESIGN--18 year follow up of male Whitehall civil servants. Plasma cholesterol concentrations and other risk factors were determined at first examination in 1967-9 when they were aged 40-69. Death of men up to 31 January 1987 was recorded. SUBJECTS--18,296 male civil servants, 4155 of whom died during follow up. MAIN OUTCOME MEASURES--Cause and age of death. Cholesterol concentration in 1967-9 and number of years elapsed between testing and death. RESULTS--1676 men died of coronary heart disease. The mean cholesterol concentration in these men was 0.32 mmol/l higher than that in all other men (95% confidence interval 0.26 to 0.37 mmol/l). This difference in cholesterol concentrations fell 0.15 mmol/l with every 10 years'' increase in age at screening. The risk of raised cholesterol concentration fell with age at death. Compared with other men cholesterol concentration in those who died of coronary heart disease was 0.44 mmol/l higher in those who died aged less than 60 and 0.26 mmol/l higher in those aged 60-79 (p = 0.03). For a given age at death the longer the gap between cholesterol measurement and death the more predictive the cholesterol concentration, both for coronary heart disease and all cause mortality (trend test p = 0.06 and 0.03 respectively). CONCLUSION--Reducing plasma cholesterol concentrations in middle age may influence the risk of death from coronary heart disease in old age.     

Cardiovascular disease with diabetes or the metabolic syndrome: should statins or fibrates be first line lipid therapy?

PURPOSE OF REVIEW: Subgroups with diabetes or with features of the metabolic syndrome have been increasingly highlighted in large clinical endpoint trials with lipid therapy. This review will focus on the results of trials with statins or fibrates and examine the strength of the evidence for major cardiovascular event reduction with each kind of therapy in these high-risk subgroups that typically have low-to-moderate levels of LDL cholesterol. RECENT FINDINGS: Of six statin trials in populations with moderately increased LDL cholesterol only one, the Heart Protection Study, has shown that statin therapy will significantly reduce the major coronary heart disease events of non-fatal myocardial infarction or coronary heart disease death in diabetes. None of these trials has shown that statins have a particular predilection for reducing cardiovascular events in individuals with higher levels of body weight or other features of the metabolic syndrome. There are far fewer trial data with fibrates than with statins. However, the Veterans Affairs High Density Lipoprotein Intervention Trial has shown that a fibrate can significantly reduce major cardiovascular events, most particularly coronary heart disease death, in those with diabetes as well as those without diabetes who have insulin resistance. Indeed, all fibrate trials show that this therapy appears to selectively benefit the individual with obesity and features of the metabolic syndrome. SUMMARY: Based principally on evidence from the Veterans Affairs High Density Lipoprotein Intervention Trial and the cumulative experience with statins, trial data would thus far suggest that the patient with a modest increase in LDL cholesterol who has diabetes or features of the metabolic syndrome might be likely to achieve more substantial cardiovascular benefit from fibrate than from statin therapy.     

不同剂量西洛他唑强化抗血小板对冠脉支架术后血小板高反应性的影响

目的：观察临床应用不同方案强化抗血小板治疗改善冠脉支架术后血小板高反应性的可行性、安全性及有效性。方法：选择2009年3月至2011年2月在沈阳军区总医院、中国医科大学第一附属医院、解放军第463医共入选560例冠脉支架术后血小板高反应性（HPR Highon-treatment Platelet Reactivity）患者,在给予阿司匹林300mg／天,氯吡格雷150mg／天,3天后HPR仍未缓解者,随机分为两组,一组在强化抗血小板治疗即阿司匹林300mg,氯吡格雷150mg的基础上加用小剂量西洛他唑（50mg,2／日）,另一组在标准两联方案即阿司匹林300mg,氯吡格雷75mg的基础上加用西洛他唑100mg,2／日,3天后测定HPR的缓解情况。结果：大剂量氯吡格雷治疗3天后HRP的缓解卒为54-3％（304／560）,接受不同西洛他唑剂量治疗3天后又有58．6％的患者HPR缓解,但是西洛他唑50mg组和100mg组HRP缓解率无差别（59．4％VS57．8％,P=0．80）。两组患者30天随访均无死亡及卒中事件,无主要及次要出血事件。结论：强化抗血小板治疗可改善冠脉支架术后的血小板高反应性且未增加出血风险,但其临床获益还需更长时间的随访结果进一步明确,两种强化抗血小板治疗方案对改善冠脉支架术后HPR的作用相似。     

Protecting the heart: a practical review of the statin studies

The aim of this review of the landmark HMG-CoA reductase inhibitors (statins) studies is to enable the clinician to draw practical lessons from these trials. The Scandinavian Simvastatin Survival Study (4S) established the importance of treating the hypercholesterolemic patient with established cardiovascular heart disease. The West of Scotland Coronary Prevention Study (WOSCOPS) showed the benefit of treating healthy hypercholesterolemic men who were nevertheless at high risk of developing cardiovascular heart disease in the future. The Cholesterol and Recurrent Events (CARE) study, a secondary prevention trial, proved the benefit of treating patients with myocardial ischemia and cholesterol levels within normal limits. This conclusion was confirmed by the Long-term Intervention With Pravastatin in Ischemic Disease (LIPID) study, another secondary prevention study that enrolled patients with a wide range of cholesterol levels (4-7 mmol/dL), into which the large majority of patients would belong. The importance of treating patients with established ischemic heart disease (IHD), and those at high risk of developing cardiovascular heart disease, regardless of cholesterol level, was being realized. The Air Force/Texas Coronary Artery Prevention Study (AFCAPS/TexCAPS) then showed that treatment can reduce adverse cardiovascular events even in the primary prevention of patients with normal cholesterol levels. The Myocardial Ischemia Reduction With Aggressive Cholesterol Lowering (MIRACL) trial showed that hypocholesterolemic therapy is useful in the setting of an acute coronary syndrome, while the Atorvastatin Versus Revascularisation Treatment (AVERT) study showed that aggressive statin therapy is as good as angioplasty in reducing ischemic cardiac events in patients with stable angina pectoris. Finally, the Heart Protection Study (HPS) randomized more than 20,000 patients, and the value of statins in reducing adverse cardiovascular events in the high-risk patient, including the elderly, women, and even in those with low cholesterol levels, is beyond doubt. The emphasis is now on the risk level for developing cardiovascular events, and treatment should target the high-risk group and not be dependent on the actual cholesterol level of the patient. It is interesting to compare the large amount of data on the value and safety of the statins with the much more limited and less convincing data on antioxidant vitamins.     

Alternative hormone replacement regimens: is there a need for further clinical trials?

PURPOSE OF REVIEW: To review the randomized trials of hormone replacement therapy. RECENT FINDINGS: Studies have shown that conjugated equine estrogen 0.625 mg a day plus medroxyprogesterone acetate 2.5 mg a day increased the risk of cardiovascular events during the first year of treatment in women both with and without coronary heart disease. Conjugated equine estrogen plus medroxyprogesterone acetate also increased the overall risk of myocardial infarction and stroke in women without coronary heart disease, and myocardial infarction or death in women with coronary heart disease, and also increased the risk of breast cancer, cognitive decline and dementia. Unopposed, oral 17B-estradiol increased the risk of stroke during the first 6 months of treatment in women with a previous stroke. Oral 17B-estradiol with or without cyclic progestin had no effect on the progression of atherosclerosis or reinfarction. Transdermal 17B-estradiol plus cyclic progestin was associated with a non-significant increase in coronary heart disease events in women with coronary heart disease. Compared with placebo, cardiovascular events increased in the ongoing estrogen-only arm of the Women's Health Initiative, indicating that unopposed conjugated equine estrogen is unlikely to be cardioprotective. However, oral 17B-estradiol retarded the progression of subclinical atherosclerosis in younger women without coronary heart disease. SUMMARY: Hormone replacement therapy should not be initiated for the primary or secondary prevention of coronary heart disease in women. A trial of 17B-estradiol started at menopause in women without coronary heart disease should be considered.     

Hypertriglyceridemia and the fibrate trials

Epidemiological studies published since 1996 have established that hypertriglyceridemia can predict risk of cardiovascular disease in a manner statistically independent of HDL cholesterol. Nevertheless, the relationship of concentrations of plasma triglycerides to risk of cardiovascular disease remains less than straightforward, partly because triglycerides are carried in lipoproteins of different atherogenicity, partly because hypertriglyceridemia is associated with non-lipid atherogenic and thrombogenic processes. For example, the association of highest risk of cardiovascular disease to moderate rather than to severe hypertriglyceridemia can be understood in terms of the distribution of triglycerides between different classes of plasma lipoproteins. It is counter-intuitive to most clinicians, however, and hence it can result in the misdirection of clinical efforts including drug therapy.Fibrates lower plasma triglycerides, and raise HDL, efficiently and with few immediate side-effects. Central to their mode of action is activation of certain nuclear receptors in cells. There is no necessary connection, however, between that fascinating biochemistry and clinical benefit as defined by reductions in rates of death by coronary artery disease. A review of trials of cholesterol-lowering by diet and drugs, published between 1966 and 1996, included 12 trials of therapy with fibrates or placebo in more than 21000 patients. Overall, these trials indicated no benefit in terms of reduction in risk of coronary deaths. The period since 1996 has seen the publication of four additional trials of treatment of 6144 patients with fibrates or placebo. Two of them were major trials. The VA-HIT was very encouraging, because treatment with gemfibrozil produced a signficant reduction in the combined incidence of fatal and non-fatal coronary events. There was no significant reduction in coronary deaths, however. The results of BIP were frankly disappointing, because they demonstrated no significant effect of treatment with bezafibrate on either the primary end-point of the trial or on rates of coronary death.Clinical indications for the use of fibrates can obviously not be based on biochemical insights, however intriguing in their own right, but they have also not been satisfactorily defined by the randomized clinical trials published to date. Hope remains, however, that some clarification will result from ongoing trials of fibrate treatment of patients with type II diabetes.     

Bilateral internal thoracic artery grafting: current state of the art

The purpose of this article is to review the key literature and assess the current status of bilateral internal thoracic artery grafting. Numerous retrospective studies have demonstrated a benefit of bilateral internal thoracic artery grafting over single internal thoracic artery grafting in terms of the long-term risk of all-cause death, cardiac-related death, and cardiac events. The survival benefit of bilateral internal thoracic artery grafting manifests relatively early after operation for high-risk patients. The skeletonization technique reduces the risk of sternal wound complications in all patients and particularly in those with diabetes. Both the left and right internal thoracic arteries have better patency when grated to the left coronary territory than saphenous vein. However, the right internal thoracic artery does not always have good patency when grafted to the right coronary artery. Bilateral internal thoracic artery grafting using the skeletonization technique is recommended for revascularization of the left coronary territory.     

The Treatment of Multiple Coronary Occlusions by Internal Mammary Artery Implantation and Omental Graft: Report on Two Human Cases

The importance of triple coronary artery disease was evident in 125 patients undergoing internal mammary artery implantation, when some patients died from right coronary artery occlusion. This occurred even when the internal mammary artery was patent and revascularizing the left ventricle.In 1961 the free omental graft operation was developed to revascularize both right and left ventricles. In animals this operation has proved most effective in preventing death after application of Ameroid constrictors to all three coronary arteries. Arteriolar or larger-sized vessels rapidly formed between the aorta and omentum and the pericardium and omentum and the heart and omentum.Two patients with triple coronary artery disease underwent internal mammary artery implantation and free omental graft early in December 1962. Postoperative convalescence was uneventful. They have returned home and appear to be improved. Wrapping the entire heart with the free omental graft has produced little reaction, suggesting that, as in the animal, the grafts are surviving.     

阿司匹林、氯吡格雷及西洛他唑预防和治疗老年冠脉支架植入术后血小板高反应性的临床效果观察

目的:探讨阿司匹林、氯吡格雷及西洛他唑预防和治疗老年冠脉支架植入术后血小板高反应性的临床效果。方法:选择60例拟行冠脉支架植入术的老年患者,随机地分为加用或未加用200 mg西洛他唑负荷剂量组。术前、术后24小时及术后30天时检测和比较各组患者的血小板聚集功能。结果:三联抗血小板治疗组的PRU、ARU及P2Y12%inhibition值均较两联抗血小板治疗组显著降低,差异具有统计学意义(P0.05)。三联抗血小板治疗和两联负荷剂量的抗血小板治疗的给药时间(第一次投药至冠脉介入治疗的时间间隔)分别为10.2小时(95%可信区间:7.4-13.1小时)和7.8小时(95%可信区间:4.5-11.2小时),三联抗血小板治疗组术前HPPR(83.3%和46.7%,P=0.003)、术后24小时(36.7%和13.3%,P=0.018)及术后30天HPPR(40.0%和16.7%,P=0.045)的发生率均较两联抗血小板治疗组明显降低(P0.05)。在术后30天的随访观察期间,两联抗血小板治疗组2例患者出现支架内血栓,并进行了血运重建术;无1例心源性死亡、缺血性卒中及出血性并发症的发生。两组次要终点的发生率比较无显著性差异(P0.05)。结论:在两联抗血小板聚集治疗的基础上附加200 mg西洛他唑可显著降低冠状动脉支架植入术后血小板的高反应性。     

Quantitative histoenzymological characteristics of the myocardium in sudden cardiac death

Enzymes in the human myocardium following sudden death were examined for activity in a quantitative histoenzymological study, these were NAD-dependent dehadrogenases of succinate (SDG), lactate (LDG), beta-hydroxybutyrate (beta-HOBDG), alpha-glycerophosphate (alpha-GPDG), alcohol (ADG), glucoso-6-phosphate (G-6-PDG), and NAD-diaphorase (NADse), and catalase. Autopsies were performed within 3 h after death. beta-HOBDG and LDG were found to show an increase in activity in the cardiomyocytes of sudden death subjects with coronary heart disease without apparent changes. In the myocardium from death subjects with coronary heart disease and large postinfarct cardiosclerosis, the activity of the enzymes was directly related to the severity of myocardial hypertrophy and signs of chronic heart failure. As myocardial hypertrophy developed, the enzyme activity increased; when there appeared signs of chronic heart failure it decreased. The myocardium from sudden death subjects with alcoholic cardiomyopathy showed diminished redox enzyme activity and higher activity of the enzyme utilizing alcohol (ADG and catalase). The findings suggest that changes in the enzyme activity in the myocardium are of various type and depend on previous cardiac abnormalities.     

Fluvastatin in the therapy of acute coronary syndrome: Rationale and design of a multicenter, randomized, double-blind, placebo-controlled trial (The FACS Trial)[ISRCTN81331696

BACKGROUND: Activation of inflammatory pathways plays an important contributory role in coronary plaque instability and subsequent rupture, which can lead to the development of acute coronary syndrome (ACS). Elevated levels of serum inflammatory markers such as C-reactive protein (CRP) represent independent risk factors for further cardiovascular events. Recent evidence indicates that in addition to lowering cholesterol levels, statins also decrease levels of inflammatory markers. Previous controlled clinical trials reporting the positive effects of statins in participants with ACS were designed for very early secondary prevention. To our knowledge, no controlled trials have evaluated the potential benefits of statin therapy, beginning immediately at the time of hospital admission. A previous pilot study performed by our group focused on early initiation of cerivastatin therapy. We demonstrated a highly significant reduction in levels of inflammatory markers (CRP and interleukin-6). Based on these preliminary findings, we are conducting a clinical trial to evaluate the efficacy of another statin, fluvastatin, as an early intervention in patients with ACS. METHODS: The FACS-trial (Fluvastatin in the therapy of Acute Coronary Syndrome) is a multicenter, randomized, double-blind, placebo-controlled study evaluating the effects of fluvastatin therapy initiated at the time of hospital admission. The study will enroll 1,000 participants admitted to hospital for ACS (both with and without ST elevation). The primary endpoint for the study is the influence of fluvastatin therapy on levels of inflammatory markers (CRP and interleukin-6) and on pregnancy associated plasma protein A (PAPP-A). A combined secondary endpoint is 30-day and one-year occurrence of death, nonfatal myocardial infarction, recurrent symptomatic ischemia, urgent revascularization, and cardiac arrest. CONCLUSION: The primary objective of the FACS trial is to demonstrate that statin therapy, when started immediately after hospital admission for ACS, results in reduction of inflammation and improvement of prognosis. This study may contribute to new knowledge regarding therapeutic strategies for patients suffering from ACS and may offer additional clinical indications for the use of statins.
