Abstract
The prevalence of coronary artery disease (CAD) and the incidence of new coronary events are similar in older men and women. Independent risk factors for new coronary events in older women include age, prior CAD, cigarette smoking, hypertension, diabetes mellitus, high serum total cholesterol and triglycerides, and low serum high-density lipoprotein cholesterol. Older women have a higher prevalence of hypertension than older men. In older women with hypertension, echocardiographic left ventricular hypertrophy is a powerful independent predictor of new coronary events, atherothrombotic brain infarction, and congestive heart failure (CHF). Older women have a higher prevalence of rheumatic mitral stenosis and of mitral annular calcium than older men. Older women and men have a similar prevalence of valvular aortic stenosis, aortic regurgitation, mitral regurgitation, hypertrophic cardiomyopathy, and idiopathic dilated cardiomyopathy. The prevalence and incidence of CHF increase with age. The prevalence of normal left ventricular ejection fraction associated with CHF increases with age and is higher in older women than in older men. The prevalence of chronic atrial fibrillation increases with age and is similar in older men and women. Atrial fibrillation is an independent predictor of new coronary events and thromboembolic stroke in older women. Older women with unexplained syncope should have 24-hour ambulatory electrocardiograms to determine whether pauses >3 seconds are present, requiring permanent pacemaker implantation.
