Persons who survive a myocardial infarction are at increasedrisk for sudden death from cardiac causes, owing largely toventricular tachyarrhythmias.1,2 The risk of sudden death aftera myocardial infarction is highest during the first 12 monthsand then declines.3,4,5,6 Although survival during the acuteand early convalescent phases after a myocardial infarctionhas improved as a result of therapies introduced during thepast 25 years,7 a delayed increase in the risk of sudden deathfrom cardiac causes after the initial convalescent phase hasbecome evident. Those in whom ventricular remodeling and heartfailure develop are at greatest risk8,9 (. . . [Full Text of this Article]
