LBSUN162 Cumulative Probability Of Heart Failure Hospitalization Among Non-Hispanic Black Compared To Non-Hispanic White Individuals With Type 2 Diabetes On Empagliflozin (EMPA-AA): Real-world Data

Abstract The results from the SGLT-2 inhibitors cardiovascular outcome trials were generalized to all, despite that non-Hispanic Black (hereafter, "Black") participants were underrepresented. Our goal was to evaluate, among patients with type 2 diabetes, the risk of heart failure hospitalizations among black vs non-Hispanic White (hereafter "White") patients initially prescribed empagliflozin. | We performed a multicenter retrospective study using clinical data derived from Electronic Medical Records (EMR's) from adults with type 2 diabetes cared for at 4 healthcare systems (UNC Health, Duke Health, MUSC, and ECU Health) who were prescribed empagliflozin between August 2014 and December 2019. Our primary outcome was time to first heart failure hospitalization. We wanted to understand if the outcomes were different in Black vs White patients with previous hospitalizations for heart failure that occurred prior to an empagliflozin prescription. Cumulative probability of heart failure hospitalization by race was estimated using the cumulative incidence function. The association of race with risk of heart failure hospitalization was evaluated using multivariable Cox hazards models. Hazard ratio (HR) and 95% confidence interval (CI) are provided as measures of strength of association and precision, respectively. | A total of 704 patients with previous heart failure hospitalizations were eligible. Mean age by race category (Black/White) was 60.2 vs 64.3 years (p < 0. 0001); 42.8% vs 61. 0% were males (p < 0. 0001) and 81.2% vs 73.2% had a history of hypertension respectively. Black patients were significantly younger and predominantly female. Cumulative probability of heart failure hospitalization at 2-years post-initiation of empagliflozin was 71.7% (95% CI = 61.6%, 79.6%) vs. 70.9% (95% CI = 64. 0%, 76.7%) for Black vs White, respectively. When adjusting for age, gender, and baseline comorbidities, there was no statistically significant difference in the risk of hospitalizations for heart failure between Black vs White patients (HR = 1. 03; 95% CI = 0.85, 1.25, p = 0.79). | In patients with type 2 diabetes with a documented previous hospitalization for heart failure prior to a prescription for empagliflozin, we found no significant difference in the cumulative probability of heart failure hospitalization in Black vs White patients.
