Prophylactic ICD does not improve survival in high-risk patients after CABG

The CABG-Patch trial randomized 900 patients with a low ejection fraction and a positive signal-averaged electrocardiogram to an implantable cardioverter-defibrillator or no defibrillator after coronary artery bypass graft surgery. There was no difference in mortality at a mean follow-up of 32 months.
