There are limited data on percutaneous coronary intervention treatment in this population. Methods Among a cohort of 4335 patients with three-vessel disease with or without left main disease undergoing percutaneous coronary intervention, 191 patients had LVEF 〈40% （low ejection fraction （EF）） and 4144 patients had LVEF _〉40%. In-hospital and long-term outcomes were examined according to LVEF. Results The estimated two-year rates of major adverse cardiac events, cardiac death, and myocardial infarction were significantly higher in the low EF group （19.64% vs. 8.73%, Log-rank test： P 〈0.01; 10.30% vs. 1.33%, Log-rank test： P 〈0.01, and 10.32% vs. 2.28%, Log-rank test： P 〈0.01 respectively）, but there was no difference in the rates of target vessel revascularization （6.18% vs. 6.11%, Log-rank test： P=0.96）. Using the Cox proportional hazard models, LVEF 〈40% was a significant risk factor for cardiac death, myocardial infarction, and major adverse cardiac events （OR （95% CI）： 4.779 （2.369-9.637）, 2.673 （1.353-5.282）, and 1.827 （1.187-2.813） respectively）, but was not a statistically significant risk factor for target vessel revascularization （OR （95% CI）： 1.094 （0.558-2.147））. Conclusion Among patients undergoing percutaneous coronary intervention for multivessel coronary artery disease, left ventricular dysfunction remains associated with further risk of cardiac death in-hospital and during long-term follow-up.展开更多
