HOMINAL, Miguel; LOPEZ², Jorge  and  ZAPATA, Gerardo. Variables associated with the restoration of ventricular function after myocardial revascularization in patients with systolic dysfunction. Insuf. card. [online]. 2015, vol.10, n.4, pp.159-163. ISSN 1852-3862.

Introduction. Myocardial revascularization is considered the best option for patients with ischemic left ventricular dysfunction. Objectives. To identify associated variables with the improvement of ejection fraction after surgical revascularization (CABG). Materials and methods. We included patients with ejection fraction (EF) <50% who underwent to CABG. We examine preoperative predictors of ventricular functional recovery. Results. We included 95 patients, 91.6% male, mean age of 63 years, 40% diabetes, 27% with prior myocardial infarction and EF average of 36 ± 6%. Myocardial viability was evaluated in 78%. After surgery, 12% presented postoperative ischemia and 28% low cardiac output syndrome. In a multivariate analysis, myocardial viability and absence of postoperative ischemia were both predictors of improvement in EF. Conclusion. Myocardial viability and absence of postoperative ischemia were both associated with improvement in post operative EF.
