The Timing of Implantable Cardioverter-Defibrillator Implantation in Patients with Heart Failure

摘要: Patients who survive a myocardial infarction (MI) are at increased risk of sudden death due to fatal ventricular arrhythmias. Implantable cardioverter-defibrillators (ICDs) reduce mortality in appropriately selected patients with heart failure and left dysfunction, regardless etiology. Post hoc analyses from landmark trials have evaluated the effect time (both since MI duration nonischemic cardiomyopathy) before ICD implantation on efficacy therapy. Time remains clinically important variable decision if when implant an ICD. Future should focus invasive and/or noninvasive stratification ischemic cardiomyopathy for better identification those would benefit early implantation, whom watch wait approach is appropriate.
