Risks of coronary heart disease in women: current understanding and evolving concepts

The population of older individuals in the United States is growing rapidly. Because women generally live longer than men and make up the majority of this aging population, the elucidation of health issues related to older women is important. Cardiovascular disease is the leading cause of death and disability for women and claims the lives of more women than the next 14 causes combined. The majority of these deaths are due to atherosclerotic coronary heart disease, with nearly 250,000 women dying of myocardial infarction each year. There is evidence that women with suspected or established cardiovascular disease have not benefited fully from recent advances in the detection and management of coronary heart disease. Regardless of the mechanism and extent of the effect that sex differences have on approaches to cardiovascular disease, women appear to benefit from proven efficacious therapies, and the longer-term outcomes associated with these treatments are positive. The data regarding women and coronary heart disease are rapidly evolving and sometimes conflicting. The intent of this article is to summarize the most current understanding of coronary heart disease risks in women, highlighting the impact of prevention, and to discuss the latest novel findings that may become important in our armamentarium for prevention of coronary heart disease.
