Most Important Outcomes Research Papers on Cardiovascular Disease in Women

Cardiovascular disease (CVD) in women has been historically understudied. For many years, heart disease had been thought to be primarily a “man’s disease.” Consequently, women have been significantly under-represented in longitudinal studies of disease history and in clinical trials. High-quality data from women at the extremes of age, with multiple co-morbidities, and from racial and ethnic minorities have been particularly rare. In order to increase awareness of cardiovascular prevention among women, in 1999 the American Heart Association (AHA) published its first women-specific clinical recommendations for the prevention of CVD.1 In 2004, the AHA and multiple other collaborating organizations subsequently sponsored “Evidence-Based Guidelines for Cardiovascular Disease Prevention in Women,” which underwent updates in 2007 and 2011. As a result of these and other related initiatives, the rate of public awareness of CVD as the leading cause of death among US women has increased from 30% in 1997 to 54% in 2009.2 CVD-associated death among US women has declined significantly over this time period.3,4 Yet substantial work still needs to be done to improve women’s cardiovascular health. CVD remains the number one killer among women.4 As the obesity epidemic continues, we are actually finding increases in coronary heart disease (CHD) death among young women 35 to 54 years of age.2 Morbidity and mortality from stroke and hypertension remain high.4 In addition, substantial outcomes disparities continue for women from racial and ethnic minorities.4 We have therefore dedicated our topic summaries in this issue of Circulation: Cardiovascular Quality and Outcomes to CVD in women. We have included only those studies where authors provided a convincing a priori reason to study a particular disease process or clinical intervention in women and reported primary endpoints that were sex-specific. We have included articles on the representation of women …
