evaluation of ejection fraction (ef) and ccsfc after coronary artery bypass graft (cabg)

introduction: coronary artery bypass graft can improve myocardial contractility and functional class in ischemic heart disease. materials & methods: this study was done on 200 patient’s with cabg operation during 6 months. 142 patients were men and 56 patients were women with mean age 57.7  9.2 years (36-83). ef was measured by echocardiography before & 1 week after cabg, ccsfc evaluated before and 3 months after surgery by questioner. data was analyzed statistically spss software. results: mean ef was 48.1  5.9 before surgery, and 48.3  8.5 after surgery. ccsfc was 2.9 0.9 before surgery and 1.10.3 after surgery (p value = 0.0001). conclusion: cabg can improve ef and reduce ccsfc in ischemic heart disease especially in patient’s with ef<35% and history of myocardial infarction.
