Relation of multicenter automatic defibrillator implantation trial implantable cardioverter-defibrillator score with long-term cardiovascular events in patients with implantable cardioverter-defibrillator

To test the hypothesis that multicenter automatic defibrillator implantation trial (MADIT) - implantable cardioverter-defibrillator (ICD) scores predict replacement requirement and appropriate shock in a mixed population including both primary and secondary prevention and long-term adverse cardiovascular events
