Abstract

Aortic stenosis (AS) is the third most common type of cardiovascular disease after hypertension and coronary artery disease, and it carries a high mortality rate when left untreated. Risk factors include male sex, hypertension, tobacco use, advanced age, elevated LDL cholesterol, and coronary atherosclerosis. Definitive treatment for AS includes valve repair, either percutaneously or surgically; however, in aging populations corrective surgery carries increased risk. While research suggests that patients of some non-White ethnic groups, including African-Americans, are less likely than their Caucasian counterparts to have AS, these minority patients may experience may experience differences in the way they receive and accept care. This paper seeks to explicate the mechanisms of racial disparities among the African-Americans affected by aortic stenosis as they pertain to healthcare utilization, referral for valve replacement, acceptance of therapy, and overall treatment outcomes.
