CABG for Ischemic Cardiomyopathy
162 patients with severe left ventricular dysfunction (Ejection Fraction<35%) who underwent CABG from 2009 to 2017 were enrolled for this study. We evaluated the short term and mid term outcomes from this retrospective study.Mean age of the study population was 58.67±9.70 years. Operative mortality was 11.62%. 30 day/in house composite outcome of stroke and perioperative myocardial infarction were 5.8%... The percentage of survival for 1 year was 86.6 %, and 5 year survival was 79.9%. 5 year event-free survival was 49.3%. The mean ejection fraction improved from 30.7 + 4.08 % (Range 18-35) to 39.9 + 8.3 % (Range 24-60). Lack of improvement of left ventricular function was a strong predictor of late mortality (HR 21.41; CI 4.33-105.95). Even though there was a trend towards better early outcome in off-pump CABG, the 5 year survival rates were similar in off-pump and on-pump group(73.4 % and 78.9 % respectively; p value 0.356). We showed that CABG in ischemic cardiomyopathy was associated with high early composite outcomes. However, the 5 year survival rates were good. Lack of improvement of left ventricular function was a strong predictor of late mortality.
