Tolerability, safety, and efficacy of beta-blockade in black patients with heart failure in the community setting: insights from a large prospective beta-blocker registry. Congestive heart failure (Greenwich, Conn.) Abraham, W. T., Massie, B. M., Lukas, M. A., Lottes, S. R., Nelson, J. J., Fowler, M. B., Greenberg, B., Gilbert, E. M., Franciosa, J.

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.
