Abstract Background Age is a risk factor for infective endocarditis, and almost half of diagnosed patients are age ≥ 60 years. Large national studies have not evaluated inpatient mortality and surgical valvular interventions between older White and Black patients hospitalized with infective endocarditis. Methods We used the Nationwide Inpatient Sample database to identify older adults ≥60 years in North America with a principle diagnosis of infective endocarditis. Multivariate logistic regression was used to compare in-hospital mortality and valvular repairs/replacement between older Black and White patients. Results Of 10,390 adults, age ≥ 60 years hospitalized for infective endocarditis during 2013 and 2014, 7356 were White and 1089 Black. Blacks were younger (mean age: 70.5 ± 0.5 vs. 73.5 ± 0.2 years, p < 0.01), lived in more zip codes with a median annual income <$39,000/yr. (40.4% vs 18.8%, p < 0.01), and had higher co-morbidity burden (Charlson comorbidity score ≥ 3: 54.6% vs 40.7%, p < 0.01). After multivariate adjustment, Blacks had higher odds for in-hospital mortality (Odds Ratio (OR) = 2.0, [Confidence Interval (CI) 1.1–3.8]; p = 0.020), and lower odds for mitral valve repairs/replacements (OR = 0.53, CI: 0.29–0.99, p = 0.049). Conclusions Blacks age ≥ 60 years hospitalized in North America with infective endocarditis are less likely to undergo mitral valvular repairs/replacement and had higher in-hospital mortality compared to White patients.
