Key result
Bypass surgery combined with defibrillator implantation resulted in similar all-cause survival (94% vs 78%, P=NS) and occurrence of shocks (66% vs 67%) compared to defibrillators alone.
Why the study?
Does combined coronary artery bypass grafting and defibrillator implantation improve survival and reduce shocks compared to defibrillator implantation alone in patients with ventricular tachyarrhythmias and ischemic heart disease?

Combined CABG and ICD was not associated with improved survival or fewer shocks; leaves open whether revascularization modifies outcomes in ischemic VT.

Does combined coronary artery bypass grafting and defibrillator implantation improve survival and reduce shocks compared to defibrillator implantation alone in patients with ventricular tachyarrhythmias and ischemic heart disease?
Absolute Event Rate: 94% vs 78%
p-value: p=NS
In patients with ventricular tachyarrhythmias and ischemic heart disease, revascularization alone is insufficient to prevent arrhythmia recurrences, supporting the combined use of CABG and defibrillator implantation.
Geelen et al. (1999) conducted a cohort in Ventricular tachyarrhythmias and ischemic heart disease (n=250). Bypass surgery and defibrillator implantation vs. Defibrillator implantation alone was evaluated on Cumulative survival from all-cause mortality (p=NS). Bypass surgery combined with defibrillator implantation resulted in similar all-cause survival (94% vs 78%, P=NS) and occurrence of shocks (66% vs 67%) compared to defibrillators alone.
