The article cites a medical research which states that in patients with left ventricular dysfunction (LVD) after coronary artery bypass grafting, ICD therapy reduced arrhythmia-related deaths by 45% but not all-cause mortality because of a substantially higher rate of nonarrhythmia-related deaths. Death from progressive pump failure in these patients may have offset the survival benefits of rapid termination of ventricular tachyarrhythmias. Furthermore, some sudden deaths are thrombotic rather than arrhythmic.
