Abstract: Heart failure (HF) clinical trials suggest different responses of blacks and whites to beta-blockers. Differences between clinical trial and community settings may also have an impact. The Carvedilol Heart Failure Registry (COHERE) observed experience with carvedilol in 4280 patients with HF in a community setting. This analysis compares characteristics, outcomes, and carvedilol dosing of blacks and whites in COHERE. Compared with whites (n=3433), blacks (n=523) had more severe HF symptoms despite similar systolic function. At similar carvedilol maintenance doses, symptoms improved in 33% of blacks vs 28% of whites, while worsening in 10% and 11%, respectively (both nonsignificant), and HF hospitalization rates were reduced comparably in both groups (-58% vs -56%, respectively; both P<.001). Incidence and hazard ratios of death were similar in blacks and whites (6.9% vs 7.5%, hazard ratio 1.2 vs 1.0, P=.276). Thus carvedilol was similarly effective in blacks and whites with HF in the community setting, consistent with carvedilol clinical trials.
