Most patients who have an out-of-hospital cardiac arrest donot survive. Thus, the use of a prophylactic implantable cardioverterdefibrillator(ICD) for the primary prevention of sudden death is a conceptuallyattractive option for high-risk patients. Several clinical trialshave previously shown that ICDs reduced mortality in patientswith coronary artery disease who had not yet had a life-threateningarrhythmia and who were selected on the basis of either theresults of electrophysiological testing or left ventriculardysfunction.1,2,3,4 In the past year, four multicenter clinicaltrials have helped refine the selection of appropriate patientsfor ICD therapy. In addition to confirming . . . [Full Text of this Article]
