41-month follow-up of risk factors correlated with new coronary events in 708 elderly patients.

A prospective study correlated coronary risk factors with new coronary events in 192 elderly men and 516 elderly women, mean age 82 +/- 8 years. Follow-up was 41 +/- 6 months (range 24-44). Coronary events (myocardial infarction, primary ventricular fibrillation, and sudden cardiac death) occurred in 64 of 192 men (33%) and in 149 of 516 women (29%), P not significant. Using univariate analysis, significant risk factors for coronary events were antecedent coronary artery disease, cigarette smoking, hypertension, diabetes mellitus, serum total cholesterol (TC) greater than or equal to 200 mg/dL and greater than or equal to 250 mg/dL, serum high-density lipoprotein cholesterol (HDL-C) less than 35 mg/dL, and serum TC/HDL-C greater than or equal to 6.5 in men and women, and obesity in women. Using multivariate analysis, significant risk factors for coronary events were age, antecedent coronary artery disease, cigarette smoking, hypertension, diabetes mellitus, and serum TC in men and women and serum HDL-C and serum triglycerides in women. Using univariate analysis, significant risk factors for coronary events in men and women with antecedent coronary artery disease were cigarette smoking, diabetes mellitus, serum TC greater than or equal to 250 mg/dL, and serum TC/HDL-C greater than or equal to 6.5. Using multivariate analysis, significant risk factors for coronary events in men and women with antecedent coronary artery disease were age, cigarette smoking, diabetes mellitus, serum TC, serum HDL-C, and serum triglycerides.(ABSTRACT TRUNCATED AT 250 WORDS)
