Racial disparities in women with ST elevation myocardial infarction: A National Inpatient Sample review of baseline characteristics, co-morbidities, and outcomes in women with STEMI

Abstract

Background: A third of the patients admitted with Acute coronary syndrome (ACS) have ST-elevation myocardial infarction (STEMI). Previous studies showed that females with STEMI have higher mortality than men. Hypothesis: There exist significant disparities in outcomes among women of different races presenting with STEMI. Methods: National inpatient sample (NIS) data was obtained from January 2016 to December 2018 for the hospitalization of female patients with STEMI. We compared outcomes, using an extensive multivariate regression analysis amongst women from different races. Our primary outcome was in-hospital mortality. Secondary outcomes were revascularization use, procedure complications, and healthcare utilization. Results: Of 202 223 female patients with STEMI; 11.3% were African American, 7.4% Hispanic, 2.4% Asian, and 4.3% another race. In-hospital mortality was higher in non-Caucasian groups. African American (adjusted odds ratio [aOR] 1.2; 95% confidence interval [CI]: 1.07–1.30; p
