Context.-Although cholesterol-reducing treatment has been shown to reduce fatal and nonfatal coronary disease in patients with coronary heart disease (CHD), it is unknown whether benefit from the reduction of low-density lipoprotein cholesterol (LDL-C) in patients without CHD extends to individuals with average serum cholesterol levels, women, and older persons. Objective.-To compare lovastatin with placebo for prevention of the first acute major coronary event in men and women without clinically evident atherosclerotic cardiovascular disease with average total cholesterol (TC) and LDL-C levels and below-average high-density lipoprotein cholesterol (HDL-C) levels. Design.-A randomized, double-blind, placebo-controlled trial. Setting.-Outpatient clinics in Texas. Participants.-A total of 5608 men and 997 women with average TC and LDL-C and below-average HDL-C (as characterized by lipid percentiles for an age-and sex-matched cohort without cardiovascular disease from the National Health and Nutrition Examination Survey [NHANES] III). Mean (SD) TC level was 5.71 (0.54) mmol/L (221 [21] mg/dL) (51st percentile), mean (SD) LDL-C level was 3.89 (0.43) mmol/L (150 [17] mg/dL) (60th percentile), mean (SD) HDL-C level was 0.94 (0.14) mmol/L (36 [5] mg/dL) for men and 1.03 (0.14) mmol/L (40 [5] mg/dL) for women (25th and 16th percentiles, respectively), and median (SD) triglyceride levels were 1.78 (0.86) mmol/L (158 [76] mg/dL) (63rd percentile). Intervention.-Lovastatin (20-40 mg daily) or placebo in addition to a lowsaturated fat, low-cholesterol diet. Main Outcome Measures.-First acute major coronary event defined as fatal or nonfatal myocardial infarction, unstable angina, or sudden cardiac death. Results.-After an average follow-up of 5.2 years, lovastatin reduced the incidence of first acute major coronary events (183 vs 116 first events;

In patients with rheumatoid arthritis, treatment with rofecoxib, a selective inhibitor of cyclooxygenase-2, is associated with significantly fewer clinically important upper gastrointestinal events than treatment with naproxen, a nonselective inhibitor.

Persons with average TC and LDL-C levels and below-average HDL-C may obtain significant clinical benefit from primary-prevention lipid modification. On-treatment apoB, especially when combined with apoAI to form the apoB/AI ratio, may be a more accurate predictor than LDL-C of risk for first AMCE.

The Air Force/Texas Coronary Atherosclerosis Prevention Study (AFCAPS/TexCAPS) is the first coronary heart disease (CHD) primary prevention trial of the cholesterol-reducing agents called "statins" to include women. For 5608 men and 997 postmenopausal women without clinical evidence of cardiovascular disease (CVD) who had average low-density lipoprotein cholesterol (LDL-C) and below average high-density lipoprotein cholesterol (HDL-C), 20-40 mg/day lovastatin reduced first acute major coronary events (AMCEs) 37% (for those receiving placebo and lovastatin, respectively, 183 and 116 first AMCEs defined as fatal or nonfatal myocardial infarction [MI], unstable angina, or sudden cardiac death; relative risk [RR] 0.63; 95% confidence interval [95% CI] 0.50, 0.79; p < 0.001). Statistically significant reductions in prespecified secondary end points (coronary revascularizations, unstable angina, MI, cardiovascular end point events, and coronary end point events) were also associated with lovastatin treatment in the overall cohort. This paper provides results in women, a prespecified subgroup. Among women, 20-40 mg/day lovastatin reduced LDL-C 25% and increased HDLC 9% (p < 0.001). A prespecified analysis revealed consistency with the overall results regardless of gender (i.e., there were no statistical differences between men and women in risk reduction for first AMCEs with lovastatin). However, the number of women who had an AMCE was small, and there was insufficient power to detect a treatment group difference among women (7 of 499 vs. 13 of 498 first AMCEs in those receiving lovastatin and placebo, respectively; RR 0.54; 95% CI 0.22, 1.35; p = 0.183). Numerical reductions in all prespecified secondary end points were observed for women treated with lovastatin, but again, the numbers of events were small and the differences were not statistically significant. Chronic long-term treatment with lovastatin was well tolerated, with no treatment group differences in the frequency of cancer, muscle symptoms, and clinically important liver enzyme elevations. In AFCAPS/TexCAPS, a consistent pattern of numerical reductions in all prespecified primary and secondary cardiovascular end points was observed in women treated with lovastatin for primary prevention of CHD. However, because of the small number of events, there was insufficient power to detect significant treatment group differences. Lovastatin treatment was associated with statistically significant decreases in LDL-C and increases in HDL-C, and chronic long-term treatment with 20-40 mg/day lovastatin was well tolerated in women.
