Key result
Black patients undergoing coronary artery bypass surgery had a significantly worse 5-year survival probability compared to white patients (64% vs 82%; adjusted HR 2.10, 95% CI 1.43-3.07).

Black patients undergoing coronary artery bypass surgery have twice the risk of death at 5 years compared to white patients, independent of preoperative risk factors and despite similar insurance coverage.

Black race associated with higher post-CABG mortality after adjustment; leaves open whether unmeasured factors or interventions can narrow disparities.
Richard J. Gray (1996) conducted a cohort in Coronary heart disease (n=3,728). Black race vs. White race was evaluated on Late survival probability at 5 years (adjusted HR 2.10, 95% CI 1.43 to 3.07, p=.001). Black patients undergoing coronary artery bypass surgery had a significantly worse 5-year survival probability compared to white patients (64% vs 82%; adjusted HR 2.10, 95% CI 1.43-3.07).
