A prospective population based cohort study in France concluded that use of statins or fibrates was associated with a 30% decrease in the incidence of stroke in seniors. The study included 7484 men and women (63%) with mean age 73.9 years and no known history of vascular events at entry in 1999-2000. Mean follow-up was 9.1 years. Lipid lowering drug users were at decreased risk of stroke compared with non-users; hazard ratios for stroke were similar for statin and fibrate. However, no association was found between lipid lowering drug use and coronary heart disease. Analyses stratified by age, sex, body mass index, hypertension, systolic blood pressure, triglyceride concentrations, and propensity score did not show any effect modification by these variables, either for stroke or for coronary heart disease. Seniors account for significant numbers of morbidity and mortality from coronary heart disease and stroke, but are underrepresented in most randomized controlled trials testing cardiovascular drugs.
