摘 要：There is a high strength of evidence that ICD therapy for primary prevention of SCD, versus no ICD therapy, shows benefit with regard to all cause mortality and SCD in patients with reduced left ventricular ejection fraction and ischemic or nonischemic cardiomyopathy beyond the immediate post-MI or coronary revascularization periods. Studies failed to show statistically significant differences for all-cause mortality across subgroups. There is insufficient evidence for all-cause mortality for patients who receive CRT-Ds versus ICD alone for primary prevention. There is high strength of evidence that in-hospital adverse events are infrequent (1-3%) and moderate strength of evidence that up to one-fifth of patients receive inappropriate shocks from the ICDs.
