Over the past decade, syncope has become increasingly recognized as an indicator of poor prognosis in patients with nonischemic dilated cardiomyopathy (NIDCM). In several clinical series, patients with depressed ejection fraction in the absence of significant obstructive coronary artery disease who experience syncope have been shown to be at high risk for sudden death with a corresponding increased rate of ventricular arrhythmias and appropriate implantable cardioverter defibrillator (ICD) therapy. Furthermore, several studies have cast doubt on the prognostic value of electrophysiological studies in these patients. This review presents the body of evidence to date surrounding the clinical implications and management of syncope in this patient population.
