Examining patient demographics and major adverse cardiac events following noncardiac surgery: Applying a health equity lens

Major adverse cardiac events (MACE) are a major contributor to postoperative complications. This study employed a health equity lens to examine rates of postoperative MACE by race and ethnicity. This single-center, retrospective observational cohort study followed patients with and without pre-existing coronary artery stents from 2008 to 2018 who underwent non-cardiac surgery. MACE was the primary outcome (death, acute MI, repeated coronary revascularization, in-stent thrombosis) and self-reported race and ethnicity was the primary predictor. A propensity score model of a 1:1 cohort of non-Hispanic White (NHW) patients and all other racial and ethnic minority populations (Hispanic and Black) was used to compare the rate of perioperative MACE in this cohort. During the study period, 79,686 cases were included in the analytic sample; 950 patients (1.2 %) had pre-existing coronary artery stents.
