title: Ischemic cardiomyopathy: midterm survival and its predictors.
abstract: BACKGROUND
  the aim of the study was to analyze all-cause mortality and predictors of long-term survival after myocardial revascularization for ischemic cardiomyopathy.
  
  
  METHODS
  data of 101 patients (mean age, 63.86 years; age range, 30-85 years; 92% male), operated on with stable coronary artery disease and left ventricular ejection fraction <30% between April 2000 and June 2010, were analyzed.
  
  
  RESULTS
  operative mortality was 1.9% (2/101). There was a significant improvement in left ventricular ejection fraction from 25.99% ± 3.8% preoperatively to 34% ± 12% postoperatively (p <0.0001). The mean duration of follow-up was 56.3 ± 33 months, and it was 97% complete (98/101). There were 18/96 (18.75%) late deaths. Overall actuarial survival at 1, 3, 5, and 10 years was 96%, 89%, 83% and 75%, respectively. Univariate predictors of late death were preoperative arrhythmia, cerebrovascular disease, peripheral vascular disease, and logistic EuroSCORE. Multivariate predictors of late death were cerebrovascular disease and preoperative arrhythmia.
  
  
  CONCLUSIONS
  our study suggests that myocardial revascularization for ischemic cardiomyopathy improves left ventricular ejection fraction and is associated with favorable long-term survival. Patients with cerebrovascular disease and preoperative arrhythmias had poorer outcomes.
