ABSTRACT
?-Blockers exert a prognostic benefit in the treatment of chronic heart failure. Their pharmacological properties vary. The only substantial comparative trial to date—the Carvedilol or Metoprolol European Trial—has compared carvedilol with short-acting metoprolol tartrate at different dose equivalents. We therefore addressed the relative efficacy of equal doses of carvedilol and metoprolol succinate on survival in single center tertiary care hospital of Dr RML Institute of Medical Sciences, Lucknow(DR RML IMS LKO) India. Two thousand and eight hundred patients with stable systolic chronic heart failure who were using either carvedilol or metoprolol succinate were identified in Medical OPD(MOPD) of Dr RML Institute of Medical Sciences, Lucknow(DR RML IMS LKO), India Patients were individually matched on both the dose equivalents and the respective propensity scores for ?-blocker treatment. During a follow-up for 17 670 patient-years, it was found that 304 (27.2%) patients died in the carvedilol group and 1066 (36.8%) in the metoprolol group. In a univariable analysis of the general sample, metoprolol therapy was associated with higher mortality compared with carvedilol therapy (hazard ratio, 1.49; 95% confidence interval, 1.31–1.69; P
