Key result
Black race was associated with worse long-term survival compared to white race after elective CABG (adjusted HR 1.4; 95% CI 1.2-1.5), but survival was similar after nonelective CABG.
Why the study?
Does black race affect long-term survival in patients undergoing elective and nonelective CABG compared to white race?

Does black race affect long-term survival in patients undergoing elective and nonelective CABG compared to white race?
Hazard Ratio: 1.4 (95% CI 1.2–1.5)
Black race is associated with worse long-term survival after elective CABG, but not after nonelective CABG, highlighting potential racial disparities in elective surgical outcomes.
Elective CABG racial survival differences merit disparity research; leaves open causal factors and intervention effects.
BACKGROUND: The effect of race on long-term survival of patients undergoing elective and nonelective coronary artery bypass grafting (CABG) is currently unknown. The purpose of this study was to compare long-term survival between black and white CABG patients by operative status. METHODS: Long-term survival of black versus white patients undergoing elective and nonelective CABG procedures between 1992 and 2011 was compared. Survival probabilities were computed using the Kaplan-Meier product-limit method and stratified by race. Hazard ratios (HR) and 95% confidence intervals (CI) were computed using a Cox regression model. RESULTS: A total of 13,774 patients were included in this study. The median follow-up time for study participants was 8.2 years. Black patients undergoing elective CABG died sooner than whites (adjusted HR = 1.4, 95% CI = 1.2-1.5). Survival was similar between blacks and whites in the nonelective population (adjusted HR = 1.0, 95% CI = 0.96-1.1). CONCLUSIONS: Black race was a statistically significant predictor of long-term survival after elective but not nonelective CABG.

Efird et al. (2014) conducted a cohort in Coronary Artery Bypass Grafting (CABG) (n=13,774). Black race vs. White race was evaluated on Long-term survival after elective CABG (HR 1.4, 95% CI 1.2-1.5). Black race was associated with worse long-term survival compared to white race after elective CABG (adjusted HR 1.4; 95% CI 1.2-1.5), but survival was similar after nonelective CABG.
