Racial disparities exist in the treatment of many cardiovascular diseases. Aortic valve replacement (AVR) is the only treatment for aortic stenosis (AS) that improves patient symptoms and survival. To date, no studies have compared the rate of AVR among different races. The records of patients with an aortic valve area <1 cm2 by echocardiography diagnosed between January 2004 and May 2010 at Barnes-Jewish Hospital were reviewed retrospectively. Patients were stratified by race. Of the 880 patients analyzed, 10 % were African American (AA), and 90 % were European American (EA). AA more frequently had hypertension (82 % vs 67 % , p <0.01), diabetes mellitus (45 % vs 32 % , p?= 0.02), chronic kidney disease (28 % vs 17 % , p?= 0.01), and end stage renal disease (18 % vs 2 % , p <0.001). AA underwent AVR less frequently than EA (39 % vs 53 % , p?= 0.02) and refused intervention more often (33 % vs 20 % , p?= 0.04). When treated, AA and EA had similar 3-year survival (49 % [38 to 60] vs 50 % [45 to 54], p?= 0.31). Identification of the factors associated with treatment refusal would further our ability to counsel patients on the decision to pursue AVR.
