title: Ten-year all-cause mortality in presumably healthy subjects on lipid-lowering drugs (from the Prospective Epidemiological Study of Myocardial Infarction [PRIME] prospective cohort).
abstract: Lipid-lowering drugs are one of the most prescribed drugs worldwide. The aim was to compare 10-year all-cause mortality according to initial dyslipidemia status and lipid-lowering drug exposure. The PRIME study was a multicenter population-based prospective cohort study of men recruited in 1991 to 1993, aged 50 to 59 years at baseline, and followed up for 10 years. The 4 groups compared were normolipidemic, untreated dyslipidemic, and dyslipidemic subjects on fibrate or statin therapy. Data were analyzed using multivariate Cox models. The cohort included 7,722 French men (statin group 4.0%, fibrate group 7.9%, untreated dyslipidemic subjects 19.0%, and normolipidemic subjects 69.1%). After 10 years, 4.8% of the sample was lost to follow-up and 416 deaths occurred (cancers 53.1%, cardiovascular diseases 17.1%, and other 29.8%). After adjustment for center, age, educational level, cardiovascular risk factors, lipids, alcohol intake, and history of cardiovascular and severe chronic diseases, hazard ratios (HRs) for all-cause mortality were 0.49 (95% confidence interval [CI] 0.26 to 0.94, p = 0.031) for subjects treated with a statin, 0.65 (95% CI 0.42 to 0.99, p = 0.046) for those on fibrate therapy, and 0.76 (95% CI 0.56 to 1.03, p = 0.080) for normolipidemic men compared with untreated dyslipidemic subjects. In the statin group, HRs for death from cardiovascular disease, cancer, and other causes were 0.55 (p = 0.348), 0.41 (p = 0.067), and 0.68 (p = 0.546) compared with dyslipidemic subjects, respectively. In the fibrate group, HRs were 0.76 (p = 0.499), 0.52 (p = 0.041), and 0.87 (p = 0.746). In conclusion, in this cohort study carried out in a real-life setting, all-cause mortality was significantly lower in dyslipidemic subjects on fibrate or statin therapy than in untreated dyslipidemic patients. No excess risk of noncardiovascular death was observed.
