|Description||Race and sex disparities are believed to play an important
role in heart disease. The purpose of this study was to examine the
association between race, sex, and number of diseased vessels at the
time of coronary artery bypass grafting (CABG), and subsequent postoperative outcomes.
The 13,774 patients undergoing first-time, isolated CABG between
1992 and 2011 were included. Trend in the number of diseased vessels
between black and white patients, stratified by sex, were analyzed using
a Cochran–Armitage trend test. Models were adjusted for age, procedural status (elective vs. nonelective), and payor type (private vs.
Black female CABG patients presented with an increasingly greater
number of diseased vessels than white female CABG patients (adjusted
Ptrend¼ 0.0021). A similar trend was not observed between black and
white male CABG patients (adjusted Ptrend¼ 0.18). Black female
CABG patients were also more likely to have longer intensive care
unit and hospital lengths of stay than other race–sex groups.
Our findings suggest that black female CABG patients have more
advanced coronary artery disease than white female CABG patients.
Further research is needed to determine the benefit of targeted preventive care and preoperative workup for this high-risk group.||en_US
