Abstract

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.

  • In the fibrate trials, the mean reduction in plasma triglyceride concentration was only 20 mg/dL to 50 mg/dL, a fraction of what would be needed to significantly reduce major vascular event risk in a short-term trial.

    “However, the mean reduction in plasma triglyceride concentration in the fibrate trials was only 20 mg/dL to 50 mg/dL, a fraction of what would be needed to significantly reduce the risk of major vascular events within a shortterm trial.”

    The Effects on Lipid Levels section reports triglycerides of 115 mg/dL with gemfibrozil versus 166 mg/dL with placebo, a 51 mg/dL difference. Contrary to the claim that a reduction of roughly this size was too small to yield a significant benefit in a trial, the Outcomes section reports a significant reduction in coronary death or nonfatal myocardial infarction, and the paper reports a significant reduction in the combined outcome including stroke. The paper does not isolate triglyceride lowering from the treatment’s other lipid effects as the cause of that benefit. (LLM, conf=0.86)

  • In VA-HIT, treatment with gemfibrozil versus placebo reduced the primary endpoint of death or nonfatal MI by 32% (P = 0.004), mortality by 41% (P = 0.02), and stroke by 40% (P = 0.046).

    The Outcomes section reports a 22% reduction in coronary death or nonfatal MI (P=0.006), not 32% (P=0.004). The copy also reports an 11% reduction in overall mortality (P=0.23) and a 25% reduction in confirmed stroke (P=0.10), rather than the claimed 41% and 40%.

  • Evidence supporting the prescription of fibrates for cardiovascular prevention remains debated.

    “Evidence supporting the prescription of fibrates for cardiovascular prevention remains debated.”

    From Established and Emerging Lipid-Lowering Drugs for Primary and Secondary Cardiovascular Prevention (2023) · cites this paper as [93]

    The discussion following Table 4 notes concern from prior fibrate studies about possible cancer-related deaths and calls for further follow-up on long-term safety. That supports some caution about prescribing fibrates, but the paper reports a significant cardiovascular benefit from gemfibrozil in the men studied; it does not establish that evidence for cardiovascular prevention with fibrates generally remains debated. Page numbers were not available in our copy. (LLM, conf=0.70)

  • Fibrates decrease triglyceride levels by 30-50% and sometimes increase HDL cholesterol.

    “Fibrates decrease triglyceride levels by 30 -50% and sometimes increase HDL cholesterol (165-168).”

    From Evaluation and Treatment of Hypertriglyceridemia: An Endocrine Society Clinical Practice Guideline (2012) · cites this paper as [166]

    The Effects on Lipid Levels section reports that, after one year, gemfibrozil lowered mean triglycerides by 31% and raised mean HDL cholesterol by 6% relative to placebo. This supports an example of the claimed effects, but the trial studied one fibrate in men with coronary heart disease; it does not establish a 30–50% range for fibrates generally. (LLM, conf=0.87)

  • In a VA-HIT substudy, patients with diabetes (n=627) compared to those without diabetes (n=142), following 5 years of gemfibrozil, had an average reduction of triglyceride levels by 31% and an increase in high density lipoprotein cholesterol of 6%; these changes were associated with a statistically significant 22% reduction in relative risk of coronary heart disease and a 24% reduction in combined

    From Fenofibrate and metabolic syndrome (2010) · cites this paper as [72]

    The Effects on Lipid Levels section reports 31% lower triglycerides and 6% higher HDL cholesterol at one year, while the Outcomes section reports a significant 22% reduction in coronary death or nonfatal myocardial infarction for the full trial. Table 2 reports a 24% reduction in the combined outcome for the full trial, and Table 3 lists 627 participants with diabetes (318 plus 309), but 1,904 without diabetes—not 142. The cited paper does not present the lipid changes or the 22% reduction as findings of a diabetes substudy after five years. (LLM, conf=0.91)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
