RT Journal Article SR Electronic T1 Interpreting the COMET trial JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 1081 OP 1087 VO 70 IS 12 A1 Tang, W.H. Wilson A1 Militello, Michael A1 Francis, Gary S. YR 2003 UL http://www.ccjm.org/content/70/12/1081.abstract AB The Carvedilol or Metoprolol European Trial (COMET; Lancet 2003; 362:7–13) found that in patients with heart failure, survival appears to be better with carvedilol than with immediate-release metoprolol tartrate. Whether the target doses used were equivalent (carvedilol 25 mg twice daily vs metoprolol tartrate 50 mg twice daily) has been debated, but the COMET trial shows that drugs in the same class do not necessarily have the same effects. Given the overwhelming evidence of the benefit of carvedilol, metoprolol succinate, and bisoprolol in patients with heart failure, we should all strive to increase the use of these drugs in appropriate doses.
