A Review of Carvedilol Arrhythmia Data in Clinical TrialsDivision of Cardiovascular Diseases, Main Line Health Heart Center, Wynnewood, PA; and Department of Medicine, Jefferson Medical College, Philadelphia, PA ß-Blockers are currently being evaluated more intensively to define their role in clinical use as antiarrhythmic agents. ß-Adrenergic blockade has been studied in relation to atrial fibrillation, ventricular arrhythmias, and sudden death; however, it is apparent from a number of studies that not all ß-blockers are equally effective. Randomized clinical trial data, both in heart failure and post-myocardial infarction (MI) patients, have shown differences in mortality benefits in addition to a variable effect on arrhythmias and sudden death. Carvedilol, a third-generation ß-blocker with proven clinical benefit in the management of heart failure and post-MI patients, has properties that may make it an effective antiarrhythmic agent. This paper reviews the current clinical arrhythmia data available for carvedilol from large-scale clinical trials and small studies. The trial evidence demonstrates that carvedilol therapy can be an effective adjunctive rate-control therapy in patients with atrial fibrillation, prevent mortality in patients with heart failure or post-MI with left ventricular dysfunction, with or without atrial fibrillation, and reduce its onset and the incidence of ventricular arrhythmia and sudden death.
