Methods A prospective observational study was conducted in FuWai Hospital from 2004 to 2009. A total of 1018 consecutive patients who had an LVEF ≤35% and New York Heart Association Class II/III heart failure at least 40 days after MI were enrolled if they were not available for implantation of an implantable cardioverter defibrillator. The degree of coronary artery disease and revascularisation were analysed. The primary outcome was SCD and secondary outcome was all-cause death. Results During a mean follow-up of 2.8 years, the SCD rate was 5% and all-cause mortality was 7.4%. The annual incidence of SCD was 1.8%. Kaplan–Meier analysis showed that the cumulative rate of SCD was significantly increased in patients with triple-vessel disease (6.7% vs 0.6%), left main coronary disease (10.3% vs 4.1%), EF ≤25% (8.3% vs 3.9%) and non-revascularisation therapy (9.6% vs 2.7%) (all log-rank, p<0.05). After multivariable Cox regression analysis, the risk of SCD was predicted by age (HR 1.05, 95% CI 1.02 to 1.09), EF ≤25% (HR 1.82, 95% CI 1.04 to 3.21) and non-revascularisation (HR 3.97, 95% CI 2.15 to 7.31). Conclusions Revascularisation may reduce the risk of SCD in post-MI patients with an LVEF ≤35% on the basis of medical therapy, and the increased risk for SCD may be predicted by age, LVEF ≤25% and non-revascularisation.
