Abstract BACKGROUND: We report the incidence of new atherothrombotic brain infarction (ABI) in older men and women with prior myocardial infarction and a serum low-density lipoprotein (LDL) cholesterol of >or=125 mg/dl treated with statins and with no lipid-lowering drug. METHODS: The incidence of new ABI was investigated in an observational prospective study of 1410 men and women, mean age 81 +/- 9 years, with prior myocardial infarction and a serum LDL cholesterol of >or=125 mg/dl treated with statins (679 persons or 48\%) and with no lipid-lowering drug (731 persons or 52\%). Follow-up was 36 +/- 21 months. RESULTS: At follow-up, the stepwise Cox regression model showed that significant independent predictors of new ABI were age (risk ratio = 1.04 for a 1-year increase in age), cigarette smoking (risk ratio = 3.5), hypertension (risk ratio = 3.1), diabetes mellitus (risk ratio = 2.3), initial serum LDL cholesterol (risk ratio = 1.01 for each 1 mg/dl increase), initial serum high-density lipoprotein cholesterol (risk ratio = 0.97 for each 1 mg/dl increase), prior stroke (risk ratio = 2.5), and use of statins (risk ratio = 0.40). The Cochran-Armitage test showed a trend in the reduction of new ABI in persons treated with statins as the level of serum LDL cholesterol decreased ( p <.0001). CONCLUSIONS: Use of statins caused a 60\%, significant, independent reduction in new ABI in older men and women with prior myocardial infarction and a serum LDL cholesterol of >or=125 mg/dl.
