Improvement of ejection fraction after coronary artery bypass grafting surgery in patients with impaired left ventricular function.

Abstract

OBJECTIVES:

The present study evaluates our experience with aorto-coronary bypass grafting in patients with severe dysfunction of left ventricle (LV) and low ejection fraction-EF(<35%). Revascularization of myocardium in this settings remains contraversial because of concerns over morbidity, mortality and quality of life.

MATERIAL AND METHODES:

Forty patients with severe coronary artery disease and dysfunction of LV (low ejection fraction <35%) underwent coronary artery bypass grafting in period of 3 years. Preoperative diagnostic of 40 patients was consisted of anamnesis, clinical exam, non-invasive methods EHO, MR and invasive diagnostic methods-cateterization. The major indication for surgery was severe anginal pain, heart failure symptoms and low ejection fraction. Internal mammary artery was used in all operated patients.

RESULTS:

Average age of patients who have been operated was 59,8. In the present study, 81,3% were male and 18,8% female. We found one-vessel disease present in 2,5% (1/40) of patients, two -vessel disease in 40% (16/40), three-vessel disease in 42,5% (17/40) and four -vessel disease in 15% (6/40) of patients. One bypass grafting we implanted in 2,5% patients, two bypasses in 42,5%, three bypasses in 45 5%, and four bypasses in 10% of patients. Left ventricular ejection fraction assessed preoperativly was 18%-27% and postoperatively was improved to 31, 08% in period of 30 days.

CONCLUSION:

In patients with left ventricular dysfunction, coronary artery bypass grafting can be performed safely with improvement in quality of life and in left ventricular ejection fraction.
