AB  - OBJECTIVE: This study evaluates whether patients with coronary artery disease and 
      severely depressed left ventricular ejection fraction (LVEF) benefit from 
      complete revascularization by multivessel coronary artery bypass. METHODS: From 
      April 1994 to May 2002, 42 patients who underwent coronary artery bypass grafting 
      (CABG) at our institution had impaired left ventricular (LV) function [an 
      ejection fraction (EF) of 30% or less]. The average preoperative LVEF was 23.8%. 
      The mean number of grafts was 4.6. Complete revascularization by multivessel 
      bypass grafting was the goal for all patients. RESULTS: Thirty days mortality was 
      0 and hospital mortality was 2.4%. The mean graft patency rate for 35 (83%) 
      patients at one month was 98.8%. The mean postoperative LVEF improved 
      significantly, from 23.8% to 35.2% (p<0.05), and the New York Heart Association 
      (NYHA) classification was improved in most patients. The Kaplan-Meier estimate of 
      survival at 5 years was 83.1%, and that of the cardiac event-free rate at 5 years 
      was 77.5%. CONCLUSION: For patients with poor LV function, complete surgical 
      revascularization by multivessel bypass grafting can be performed safely, with 
      satisfactory hospital mortality and long-term results.
