It doesn't even need to be blinded if the endpoint is MI or death. Death is hard to fool yourself about. Big MIs also eventually get objectively detected, one way or the other. The literature on cholesterol intervention and coronary heat disease (CHD) and total mortality risk is now so large that it's necessary to go to the meta analysis level to get anything short enough to be discussed on a newsgroup. So I'm presenting it at that level below. My general synthetic take: lowering cholesterol decreases CHD risk and total mortality risk IF it's done with statins, niacin, or diet, or any combo of these. It is said that it may take some minimal 5-10 % reduction to be worth doing mortality-wise, but those figures include fibrate data, and this should be broken out. The epidemiologic total mortality news for fibrate (Lopid-type) drugs is bad, and they're responsible for nearly ALL of the intervention trial negative TOTAL mortality data. With the relatively crumby support for their benefits, I'm frankly surprised they entire class has not been made illegal. It's a matter of getting into a bad thing slowly, I suppose. PPARalpha (I suspect) is a signal transduction colon cancer promoter like PPARbeta and you don't want to mess with it, with fibrates (we don't yet know about the "glitazone" PPARgamma agonists, but they may work in the opposite direction, and be cancer inhibitors). In any case, though, two old fibrates are implicated in increased mortality, and nobody yet knows anything epidemiologically about the relatively new micronized fenofibrate (Tricor). Obviously somebody's got a new patented drug to shove. I wouldn't take it if I were you! If you have horrid triglyceride levels, talk to your doc about fishoil. Salmon every day's not going to kill you, but a fibrate might. The data for beneficial fibrate effect on heart disease is mild. The best argument for them is the gemfibrazole VA-HIT study which found a reduction in cardiac events. It was probably underpowered and didn't find any reduction in cardiac mortality. Mention that to the Lopid drug-rep guy who tells you it had no negative effect on mortality. If it had no positive effect even on *cardiac* mortality, the study was definitely too underpowered to comment on *total* mortality. Polyunsaturated fats, interestingly, seem to increase colon cancer incidence as well (there is animal and human data which is not quoted below), and there is epidemiologic evidence (posted in another message) that low-cholesterol is an independent risk for cecal cancer and it may be that anything that lowers cholesterol does this. Somebody needs to break the cecal colon cancer risk out of the statin and niacin trial data, if they haven't already. Perhaps it's getting diluted in this and other cholesterol lowering trials, by other cancers on which the treatment has no effect. This would be good to know. If a single narrow cause of mortality goes up from a drug, it can still get swamped by all the good things it does. This data does generally support the idea that LDL is a direct causal CHD risk-factor. You can argue all you like about the statins just happening to have some other benefit than the one they were designed for, but you cannot then explain the diet and niacin studies, nor even (for that matter) the narrow effect of certain fibrates on CHD-events alone (if you don't count the cancer they probably cause). Also, you have to throw out the familiar hypercholestolemia literature, and a huge amount of animal CHD model intervention literature, including studies on primates. Too many strands of evidence from too many different sources! No, nature doesn't give us coincidences that large. If you have to explain away results that don't fit your hypothesis from 10 different kinds of studies, and you have to do it in ten different kind of post-hoc and ad-hoc ways, this should be a clue that maybe you're wrong. <g> So, anyway here are the 8 abstracts everybody who thinks of treating cholesterol should have read. --Steve Harris, M.D. 1: Circulation 1999 Mar 2;99(8):E1-7 Lowering LDL cholesterol: questions from recent meta-analyses and subset analyses of clinical trial DataIssues from the Interdisciplinary Council on Reducing the Risk for Coronary Heart Disease, ninth Council meeting. Gotto AM Jr, Grundy SM. Cornell University Medical College, New York, NY 10021, USA. dean@mail.med.cornell.edu The benefit of cholesterol-lowering therapy in the prevention of coronary heart disease (CHD) is well established. The secondary prevention Scandinavian Simvastatin Survival Study (4S) and the primary prevention West of Scotland Coronary Prevention Study (WOSCOPS) demonstrated that lipid lowering with a statin can dramatically and cost-effectively reduce CHD morbidity and mortality with no increase in noncardiovascular mortality. The Cholesterol and Recurrent Events (CARE) trial extended benefit to CHD patients without high cholesterol. Post hoc analyses of data from these large trials are contributing to speculation, driven by subset analyses and meta-analyses, about whether cholesterol intervention should be target based, as current guidelines recommend. Whereas CARE data support the importance of baseline LDL cholesterol (LDL-C), with greatest clinical event risk reduction in the upper part of the LDL-C range in the trial, 4S found no difference in outcome according to baseline LDL-C in a quartile analysis, and WOSCOPS found no linear relation between decrease in LDL-C and decrease in relative risk for CHD. Furthermore, WOSCOPS showed no additional clinical benefit with LDL-C lowering beyond approximately 24%. Questions raised by such analyses require answers from prospective, hypothesis-based data, and at present there is no compelling argument for moving away from LDL-C targets. The hypothesis-based findings of 4S, CARE, and WOSCOPS support current clinical guidelines, and lowering LDL-C may reduce risk more substantially than might have been predicted.

[Article in Spanish] Fernandez-Cruz A. Servicio de Medicina Interna, Hospital Universitario San Carlos, Universidad Complutense, Madrid. Much debate on the benefits and risks of cholesterol lowering to prevent coronary heart disease has focused on excess non-CHD mortality rates reported in some trials. Because of the wide variation in design of cholesterol-lowering trials and because the non-CHD mortality rate was not a controlled endpoint of statistical power in most published studies, it has been difficult to determine whether any excess mortality was due to certain therapies, to other mechanisms, or to chance. As a result, some investigators have performed retrospective analyses of pooled trial data in order to augment statistical power. Some investigators have hypothesized that the human brain is dependent on a constant supply of cholesterol from the circulation and that cholesterol loss in neuronal membranes, with the possible consequences of behavioral disorders and increased risk of accident and violent death. Indeed Weidner and Griffin suggest that low cholesterol is a marker for poor underlying health; physical illnesses are likely to cause depression and other negative emotional states, which are often accompanied by suppressed appetite and weight loss causing reduction in cholesterol levels. Such mental states may also increase the risk of non-CHD death, for example suicide. Rossouw reviews the evidence concerning non-CHD mortality in cholesterol-lowering trials and reports metaanalyses carried out for all trials combined. The findings indicated a significant (15%) increase in non-CHD mortality in all trials combined. However, this was not related to cholesterol lowering itself, because there was no increased risk in trials with > 10% cholesterol reduction, whereas there was a significant (22%) increase in trials with lesser degrees of cholesterol lowering. The publication of a large secondary prevention trial (4S) employing Simvastatin for cholesterol lowering supports the idea that cholesterol reduction itself does not have adverse effects on non-CHD mortality. The overview of all published trials demonstrates their effectiveness in reducing cholesterol and provides clear evidence of benefits on stroke and total mortality. A 10% reduction in cholesterol yielded about a 20% decrease in CHD mortality, which would be expected to result in about a 6% reduction in total mortality. Endothelium-dependent relaxations are reduced in hyperlipidemia and atherosclerosis. Exogenous L-arginine improves or restores the reduced endothelium-dependent relaxations. Moreover inflammation is associates with the initiation and progression of atherosclerosis. The fact of the matter is the Cardiovascular drugs already in clinical use or in development are able to interfere with certain aspects of endothelial function and may be useful in protecting the vessels and, hence, in preventing the development of cardiovascular disease.

Borgia MC, Medici F. Universita Degli Studi di Roma La Sapienza, Italy. In this review the indications for the available treatments for dyslipidemias in the prevention of coronary heart disease (CHD) are considered, and their efficacy according to the latest studies is analyzed. As data sources the authors used the main multicenter studies performed in the last twenty years to evaluate primary and secondary prevention of CHD by correcting dyslipidemias as well as the results of meta-analyses of these studies. All treatments considered were found effective in preventing CHD morbidity and mortality to some extent. In particular, the combination of diet with niacin or hydroxymethylglutaryl coenzyme A (HMG CoA) reductase inhibitors seems to give the best results. These drugs induce a marked reduction of total and low-density lipoprotein (LDL) cholesterol and an increase of high-density lipoprotein (HDL) cholesterol concentrations. The use of diet, niacin, and HMG CoA reductase inhibitors reduces total as well as specific mortality. Treatment of dyslipidemia to prevent CHD depends on the pattern and severity of dyslipidemia, the presence of overt CHD, and the patient's response to diet. Pharmacologic treatment should be started only after dietary modifications have been tried and must be combined with diet. Drug side effects must also be considered, for they may affect patient compliance. High levels of total and LDL and low levels of HDL cholesterol are major risk factors for coronary atherosclerosis. Correcting lipid abnormalities can reduce the risk of development or progression of CHD. Diet and drugs are the main instruments available to normalize lipid levels. The choice of drug to combine with diet must be based on its specific effects on lipid metabolism, side effects, and efficacy in reducing CHD.

Gould AL, Rossouw JE, Santanello NC, Heyse JF, Furberg CD. Merck Research Laboratories, West Point, PA 19486, USA. goulda@merck.com BACKGROUND: We determined the effect of incorporating the results of eight recently published trials of Hmg CoA reductase inhibitors ("statins") on the conclusions from our previously published meta-analysis regarding the clinical benefit of cholesterol lowering. METHODS AND RESULTS: We used the same analytic approach as in our previous investigation, separating the specific effects of cholesterol lowering from the effects attributable to the different types of intervention studied. The reductions in coronary heart disease (CHD) and total mortality risk observed for the statins fell near the predictions from our earlier meta-analysis. Including the statin trial findings into the calculations led to a prediction that for every 10 percentage points of cholesterol lowering, CHD mortality risk would be reduced by 15% (P<.001), and total mortality risk would be reduced by 11% (P<.001), as opposed to the values of 13% and 10%, respectively, reported previously. Cholesterol lowering in general and by the statins in particular does not increase non-CHD mortality risk. CONCLUSIONS: Adding the results from the statin trials confirmed our original conclusion that lowering cholesterol is clinically beneficial. The relationships (slope) between cholesterol lowering and reduction in CHD and total mortality risk became stronger, and the standard error of the estimated slopes decreased by about half. Use of statins does not increase non-CHD mortality risk. The effect of the statins on CHD and total mortality risk can be explained by their lipid-lowering ability and appears to be directly proportional to the degree to which they lower lipids.

Gould AL, Rossouw JE, Santanello NC, Heyse JF, Furberg CD. Merck Research Laboratories, West Point, Pa 19486, USA. BACKGROUND: There has been a continuing debate about the overall benefit of cholesterol lowering. We performed a novel meta-analysis of all randomized trials of more than 2 years' duration (n = 35 trials) to describe how coronary-heart-disease (CHD), non-CHD, and total mortality are related to cholesterol lowering and to type of intervention. METHODS AND RESULTS: The analytic approach was designed to separate the effects of cholesterol lowering itself from the other effects of the different types of intervention used. For every 10 percentage points of cholesterol lowering, CHD mortality was reduced by 13% (P < .002) and total mortality by 10% (P < .03). Cholesterol lowering had no effect on non-CHD mortality. Certain types of intervention had specific effects independent of cholesterol lowering. Fibrates (clofibrates, 7 trials; gemfibrozil, 2 trials) increased non-CHD mortality by about 30% (P < .01) and total mortality by about 17% (P < .02). Hormones (estrogen, 2 trials; dextrothyroxin, 2 trials) increased CHD mortality in men by about 27% (P < .04), non-CHD mortality by about 55% (P < .03), and total mortality by about 33% (P < .01). No specific effects independent of cholesterol lowering were found due to diet (n = 11) or other interventions (resins, 5; niacin, 3; statins, 2; partial ileal bypass, 1). CONCLUSIONS: The results suggest that cholesterol lowering itself is beneficial but that specific adverse effects of fibrates and hormones increase the risk of CHD (hormones only), non-CHD, and total mortality.

Holme I. This editorial reports on a meta-analysis done on cholesterol-lowering trials. Coronary heart disease incidence is reported for 16 trials and total mortality for 19 trials. The cholesterol benefit ratio, i.e., the percent risk reduction divided by the percent cholesterol reduction, was analyzed in terms of total vs. potential modifying factors. For coronary heart disease the benefit ratio was 2.8 (95% CL: 1.5, 4.2), and for total mortality it was 1.2 (95% CL: -0.1, 2.3). Cholesterol reduction had to be at least 8-9% to outweigh the negative impact of treatment on total mortality.

Holme I. Life Insurance Companies' Institute for Medical Statistics, Ulleval Hospital, Oslo, Norway. This paper reports on a meta analysis in twenty-two randomized both single and multifactor trials regarding the effect of designed cholesterol reduction on total mortality and CHD incidence. Per cent reduction in CHD incidence was 2.5 for every per cent associated net reduction in total cholesterol, but was only 0.74% for total mortality. Since total net reduction in cholesterol was about 5% in all trials combined, the number of participants was far too small to demonstrate a significant expected reduction of 4% in total mortality. However, the 4% reduction lies just outside the observed 95% confidence limits of the overall estimate of effect on total mortality (OR = 1.02; CL 0.97, 1.07). It is concluded that cholesterol reduction must be much larger than 5% to be able to reduce the relative risk of CHD substantially and total mortality moderately.

A meta-analysis of cholesterol-lowering trials. Silberberg JS, Henry DA. University of Newcastle, Shortland, NSW. OBJECTIVE: To use meta-analysis to estimate the benefits of drug treatment to lower cholesterol levels in the primary and secondary prevention of coronary heart disease (CHD) events. DATA SOURCES: MEDLINE search from 1967 to 1990; bibliographies of review articles. STUDY SELECTION: Nine trials met the entry criteria: they were monofactorial, randomised and controlled. DATA EXTRACTION: Two independent, unblinded observers. DATA SYNTHESIS: The odds ratio (and 95% Cl) for death from CHD was 0.85 (0.64, 1.14) in primary prevention and 0.84 (0.75, 0.95) in secondary prevention studies when calculated by the method of Peto. The event rate in the secondary prevention studies was higher than that in the primary prevention studies, and the absolute risk reduction achieved by therapy in the former (3.2%) was much higher than that in the latter (0.1%). The number of subjects needing to be treated to prevent one death from CHD was 38 in secondary prevention and 675 in primary prevention. Results with the method of DerSimonian and Laird were similar. CONCLUSIONS: The benefits of cholesterol lowering to prevent death from CHD are substantially greater in the secondary prevention setting than in primary prevention.

Comments: Only because of hidebound traditionalism. Why give or take this drug? You're treating a lab test number. Nobody has shown that fibrates do anything for anybody. A meta analysis of 21,000 people in 12 trials over 30 years showed nada. Two major trials have been done since then: VA-HIT in 6,144 patients which found a reduction in cardiac events but not cardiac deaths. The Benzafibrate Infarction Prevention (BIP) Trial with even more patients (8,200) didn't EVEN show a reduction in cardiac EVENTS, let alone cardiac deaths or total deaths. The statin drugs in trials of the size and power of these last two studies have showed not only cardiac death reduction but all-cause mortality reduction. If fibrates are ever shown to save any lives, it will take studies larger than those which have ever been done in the history of cardiology to prove it. It's time to admit that on the basis of a huge number of patient years of study, fibrates appear to be CLINICALLY worthless drugs. By "clinically," I mean that they fix lab numbers (triglycerides, HDLs) wonderfully, but have not been proven to anything clinically for patients ("klinikos = at the bedside, referring to how ill your actual human patient is, judged by how ill you think he'd be if you hadn't seen his lab results). Any positive evidence for fibrates is outweighed by far more than an equal number of patient years showing no effect. And even the positive evidence is mild. Faced with all this evidence, at once, the FDA would never approve fibrates as a new class of drugs today. They've been grandfathered in, and they suck. One hears a sort of wistful but supportive tone in the review articles, as though a mother were discussing her children's D+ grade report cards. Sorry, but this is not the way medicine is supposed to work. Fibrates may yet prove useful for some subset of patients, but as of now, NO SUCH SUBSET has been identified. Meanwhile, these things are expensive, and there's some epidemiological evidence that they're dangerous. A conservative doctor would not use them, on the basis of what we know. Their continued use is on the basis of tradition, which it's time we changed. Lest you think that standard FDA approved drugs are incapable of killing patients in search of fixing numbers, before it's been shown that the drugs actually don't save lives and indeed are dangerous, I will refer you to the 1993 CAST trial results, in which the anti-arhythmics (vs. no treatment) killed patients with a p of 0.003. SBH Curr Opin Lipidol 2000 Dec;11(6):609-14 Hypertriglyceridemia and the fibrate trials. Faergeman O. Department of Medicine & Cardiology, Aarhus Amtssygehus University Hospital, Aarhus, Denmark. 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 significant 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.

In the vicinity of 30-100 mg a day, probably, with your highest fat meals. If you can afford it. Note that Baycol (popular cheap high potency statin class drug), has been pulled from the market for causing deaths, as reported yesterday and today. It's one of the me-too statins for which there was no long, multi-year study. Like Lescol, etc. Which cut the price. It may be that this is not safe. Thus, we may have to stick to the better tested statins like Mevacor, Zocor, Pravachol.

Obviously because he started out with cholesterol dangerously high. Consulting his doc and cutting his Lipitor dose in half and rechecking later is an option. Generally the target has been LDL of 100. On the other hand, if there are no side effects or enzyme abnormalities noted, there is not as yet any evidence that you can lower cholesterol "too much" with statins. If anything, the evidence is the reverse-- in secondary prevention trial in both stroke and MI, those with lower cholesterols to begin with benefited from statin therapy nearly as much. And of course they went even LOWER than they had started. SBH From: Steve Harris <sbharris@ix.netcom.com> Newsgroups: sci.med,sci.med.cardiology Subject: Re: Does high chol. promote heart disease?

Familial hypercholesterolemia comes in two varieties-- the one gene "single dose" and the two gene "double dose" which is worse. The double dose gives cholesterols over 600 mg/dL (15.5 in SI units). This usually produces heart attacks before 30. The single dose variety gives cholesterols around 300 to 400 (roughly 8 to 10 SI). Men have 85% chance of heart attack by age 60, women by age 70. There is no single "cholesterol pill," but a wide variety of them. We know enough about the fibrates (Tricor/fenobibrate, gemfibrozil/Lopid, etc) and the cholesterol binders (Questran) to know they aren't worth taking. The statins, a third class of drug, work well in people who've had a heart attack or have diabetes, but haven't yet proven themselves in people merely at risk from modestly high cholesterol. However, they haven't been tried to see if they prevent death in people with VERY high cholesterol and not yet any heart attack, so that's a matter of guesswork. My guess is yes, and if it had a cholesterol > 300 I'd certainly be on one. If you try a statin, stick with the old and proven ones for which there are long clinical trial data available (mevastatin simvastatin, pravastatin). Refuse Lipitor and Crestor. Any statin can cause side effects and needs to be stopped instantly at the first sign of muscle pain, mental problem, numbness, or really ANY symptom of ill health. There's a new non-statin drug which is a cholesterol resorption inhibitor called Zetia (ezetimibe), available both with and without statin. Mechanistically it is expected not to be too dangerous and so far looks clean. However, it's new, and one should be wary of new drugs. It lowers cholesterol well, but there's no data yet to show it prevents MIs, let alone death. It's an option for those who cannot take statins. Niacin, for which much more experience is in, prevents MIs but studies are not large enough to show it prevents death. It has side effects which are usually more annoying than problematic, but it can cause liver damage if not carefully followed. The best of all treatments to start with for those at risk for heart disease is high dose fishoil EPA/DPA concentrate (5 to 10 grams of 50% concentrate a day). There is a LONG experience of humans on high fish fat diets, and the stuff is benign. It lowers triglycerides a great deal and LDL modestly (at high dose). But it's protective against heart disease death in ways which have nothing to do with cholesterol levels (we don't know the mechanism). Most people with major cardiac risk factors should be taking an aspirin a day, unless they have a reason not to. See a cardiologist and then get a second opinion. Get on fish oil. Fish is not enough unless you make sure it's red (sockeye) salmon. Good luck. And remember finally that you may not be afraid of death, but if you're afraid of pill side effects, you're not certainly not fearless. If you're not afraid of being a cardiac cripple in a wheelchair on chronic oxygen for your congestive heart failure, it's only because you haven't seen it. That may not be a "dangerous side effect" but it's certainly a nasty *effect* of heart disease. The worst thing about heart disease is sometimes you *don't* die. It makes no sense to fear side effects from a pill when you could be looking a chronic disability just as awful, from the disease itself. You can always stop a pill if you're alert to the problems it can cause. One hears stories of permanent side effects from statin use, but they are hard to evaluate. And even they don't come from people who stopped the drug immediately at the first sign of problem. So take them for what they are worth: stories to pay attention to, but not to bet your life on.

Is it just worthless for cholesterol control? My triglyclerides have dropped from over 4,000 mg/dL to 150 mg/dL - not great, but much better. << COMMENT: Lopid certainly brings triglycerides down very well. That is the place where it shines best (rather than as a treatment for high cholesterol or LDL per se). Whether this prevents death from heart disease in the small subset of people who have VERY high triglycerides (like you) is an open question. Nobody has looked. In the largest studies on Lopid, they gave it to a broad range of people and did not succeed in showing decrease in mortality. Perhaps if they'd restricted it to a subset, they might have. We don't know! YOU do have an unusual problem, for which no endpoint data from fibrate treatment are known. 4000 is a VERY high triglyceride level-- high enough to cause worry of other problems, like pancreatitis. For you, I think a fibrate is reasonable. However, if I were you, I would recommend you do the 10 grams of fishoil a day and see if you can then cut down your fibrate dose. Here's a very large trial of gemfibrozole in men with coronary disease where they were unable to show a decrease in heart disease death, or death from any cause. They had to fold in total non-fatal events to get anything significant. But since fibrates are carcinogens, a 24% decrease in non-fatal events is not enough. Note, however, that these men did not have really high triglycerides and weren't chosen for that. It's still possible that gemfibrozil would have done better for them, if they had been. These are NOT the same group as you, though. We really have no good data for people with your problem, and that's the problem. N Engl J Med. 1999 Aug 5;341(6):410-8.

Center for Chronic Disease Outcomes Research, Veterans Affairs Medical Center, Minneapolis, MN 55417, USA. bloom013@tc.umn.edu BACKGROUND: Although it is generally accepted that lowering elevated serum levels of low-density lipoprotein (LDL) cholesterol in patients with coronary heart disease is beneficial, there are few data to guide decisions about therapy for patients whose primary lipid abnormality is a low level of high-density lipoprotein (HDL) cholesterol. METHODS: We conducted a double-blind trial comparing gemfibrozil (1200 mg per day) with placebo in 2531 men with coronary heart disease, an HDL cholesterol level of 40 mg per deciliter (1.0 mmol per liter) or less, and an LDL cholesterol level of 140 mg per deciliter (3.6 mmol per liter) or less. The primary study outcome was nonfatal myocardial infarction or death from coronary causes. RESULTS: The median follow-up was 5.1 years. At one year, the mean HDL cholesterol level was 6 percent higher, the mean triglyceride level was 31 percent lower, and the mean total cholesterol level was 4 percent lower in the gemfibrozil group than in the placebo group. LDL cholesterol levels did not differ significantly between the groups. A primary event occurred in 275 of the 1267 patients assigned to placebo (21.7 percent) and in 219 of the 1264 patients assigned to gemfibrozil (17.3 percent). The overall reduction in the risk of an event was 4.4 percentage points, and the reduction in relative risk was 22 percent (95 percent confidence interval, 7 to 35 percent; P=0.006). We observed a 24 percent reduction in the combined outcome of death from coronary heart disease, nonfatal myocardial infarction, and stroke (P< 0.001). There were no significant differences in the rates of coronary revascularization, hospitalization for unstable angina, death from any cause, and cancer. CONCLUSIONS: Gemfibrozil therapy resulted in a significant reduction in the risk of major cardiovascular events in patients with coronary disease whose primary lipid abnormality was a low HDL cholesterol level. The findings suggest that the rate of coronary events is reduced by raising HDL cholesterol levels and lowering levels of triglycerides without lowering LDL cholesterol levels.
