[Prevalence and clinical course of patients in Spain with acute myocardial infarction and severely depressed ejection fraction who meet the criteria for automatic defibrillator implantation].
The Multicenter Automatic Defibrillator Implantation Trial (MADIT)-II has broadened the indications for cardioverter defibrillator implantation. We present a retrospective study designed to estimate the number of patients in Spain eligible for an implantable defibrillator according to the MADIT-II criteria. From January 1999 to October 2002, 758 consecutive patients were admitted to our center with the diagnosis of acute myocardial infarction. Sixty-seven had a left ventricular ejection fraction < or = 30% (mean, 23[5]) and were not eligible for revascularization. Excluding patients older than 80 years and patients with marked co-morbidity, 47 patients met the MADIT-II criteria for an implantable defibrillator. After a mean follow-up of 18 months, there were 20 deaths, 6 of which were considered sudden. In conclusion, application of the MADIT-II criteria for defibrillator implantation may benefit 6% of the patients with myocardial infarction in Spain. This proportion translates as 4110 defibrillator implantations.
