PAREPET II_Prediction of ARrhythnic Events with Positron Emission Tomography II

? DESCRIPTION (provided by applicant): Using current guidelines, only one-quarter of patients receiving an implantable cardiac defibrillator (ICD) for primary prevention of sudden cardiac arrest (SCA) receive appropriate ICD therapy within 5 years. PAREPET (Prediction of ARrhythmic Events with Positron Emission Tomography) identified four independent risk factors that predict SCA or ICD equivalent (SCAE) in subjects with ischemic cardiomyopathy. At optimized cut-points, the absence of these risk factors identified 38% of the cohort at very low risk of SCAE (
