title: Drug and drug-device therapy in heart failure patients in the post-COMET and SCD-HeFT era.
abstract: Reduced left ventricular ejection fraction and heart failure are the most important risk factors for sudden cardiac death. Recent trials have contributed to the knowledge base of critical therapies for the treatment of left ventricular systolic dysfunction and heart failure as it relates to arrhythmic and sudden cardiac death. Both pharmacologic and device therapies can reduce sudden cardiac death. The trials discussed in this paper have identified the pharmacologic and device interventions that are likely to improve the length and quality of life of the patient with left ventricular dysfunction and reduce the risk of sudden cardiac death. The mortality and anti-arrhythmic effects of angiotensin-converting enzyme inhibitors and beta-blockers have been confirmed in large-scale controlled clinical heart failure trials. Recent trials have evaluated which agents are most effective and which patients will derive the most benefit from device therapy in terms of the reduction in the risk of sudden cardiac death and in the amelioration of heart failure. The recent data from the Carvedilol or Metoprolol European Trial (COMET) and the Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT) are discussed as the latest in the series of landmark studies that have shaped the current approaches to treating patients with heart failure and that have altered the heart failure treatment paradigm.
