Explaining Racial Disparities in Outcomes After Cardiac Surgery

Authors:

Abstract
Growing evidence suggests that disadvantaged populations have higher mortality rates after a wide range of surgical procedures.1-4 Coronary artery bypass graft (CABG) surgery is an example of a high-risk, routine procedure after which we observe significant disparities in operative mortality rates. A large study using National Inpatient Sample outcomes data from 1.2 million CABG procedures found that, compared with white men, in-hospital mortality was 55.6% higher for black women and 35.6% higher for black men.3 Another study using the Society of Thoracic Surgeons National Database, the largest clinical registry in this specialty, found that black patients have a 29% higher operative mortality for CABG surgery than white patients.5
