Time-dependence of appropriate implantable defibrillator therapy in patients with ischemic cardiomyopathy.

摘要

INTRODUCTION: Little is known about the risk of appropriate implantable cardioverter-defibrillator (ICD) therapy outside the context of controlled clinical trials where routine practice patients are followed for longer durations and questions of device replacement frequently arise. We assessed the incidence and time-dependence of appropriate ICD therapy in a routine clinical practice primary prevention population with prior myocardial infarction (MI) and reduced left ventricular ejection fraction (LVEF). METHODS AND RESULTS: Patients with prior MI and LVEF
