Introductions: The Society of Thoracic Surgeons’ risk score identifies the AA and Hispanic races as an independent risk factor for perioperative morbidity but not mortality in patients undergoing isolated AVR. We aim to investigate the effect of race on mortality and morbidity of AVR in a large contemporary nationwide database.
Methods: The 2004-2013 Nationwide Inpatient Sample was utilized to identify 108,673 patients who underwent isolated AVR. In-hospital outcomes of AA patients (n=5,921) and of Hispanics patients (n=6922) in comparison to propensity matched cohorts of the Caucasian patient's population (n=95.830).
Results: In-hospital mortality was significantly higher in AA undergoing AVR compared with Caucasian patients (6.1% vs. 4.7%, OR 1.21, CI 1.02-1.44, p=0.03). Key perioperative complications were not significantly different between the two groups. There was no significant difference in mortality between Hispanic patients compared with Caucasian patients undergoing AVR (4.5% vs. 4.1%, OR 1.05, CI 0.88-1.27, p=0.58). Key perioperative complications were also not significantly different between the Hispanic and Caucasian groups (Figure 1).
Conclusions: In a large contemporary sample of patients undergoing AVR, African American but not Hispanic race was an independent predictor of in-hospital mortality. These findings have important implications for preoperative risk stratification of African American and Hispanic patients being evaluated for aortic valve replacement.
