Obesity and diabetes in heart disease in women

Abstract

Heart disease remains a major health threat in women. Cardiometabolic risk factors such as obesity and diabetes differentially and adversely impact heart disease risk. Although obstructive coronary artery disease is an important cause of ischemic heart disease in women and is prognostic, women are more likely to have angina and myocardial ischemia without obstructive atherosclerosis, which has been attributed to coronary microvascular dysfunction (CMD). Heart failure with preserved ejection fraction (HFpEF) is another condition that predominates in women. CMD and HFpEF are both associated with cardiometabolic risk factors that are prevalent in women. Women are also more likely to have additional risk-enhancing conditions such as autoimmune dysfunction, chronic inflammation, and sex-specific hormonal factors that adversely influence risk. In this review, we focus on cardiometabolic risk factors of obesity and diabetes in heart disease in women, including ischemic heart disease from CMD, HFpEF, and arrythmias. Team-based care to focus on cardiometabolic risk reduction is needed to alter adverse heart disease outcomes in women. Identification, education, treatment, and active surveillance of these dysmetabolic risk factors are imperative in the primary and secondary prevention of heart disease in women.
