Objectives: The aim of this study was to evaluate the left ventricular functions with transthoracic echocardiography after coronary bypass surgery.
Methods: Sixty-four patients who underwent coronary bypass surgery between January 2008 and March 2009 were retrospectively evaluated. The diagnosis, age and gender of the patients, presence of diabetes mellitus and/or hypertension, smoking, and left ventricle functions before and after surgery were recorded.
Results: The mean age of the patients was 58 ± 6,2 years. Forty-four of 64 patients were male, and 20 were female. The lowest ejection fraction was measured in two patients as 30% preoperatively. The mean preoperative and postoperative left ventricle ejection fractions were 48 ± 5.4% and 58 ± 2.4% respectively. This difference was found statistically significant. The mortality rate of by-pass surgery was 4.68% (3 patients).
Conclusion: The left ventricular functions were significantly recovered after coronary by-pass surgery.
