Left ventricular dysfunction increases the rate of mortality and morbidity after coronary artery bypass grafting (CABG).


Thirty seven consecutive patients with low ejection fraction (EF) who underwent CABG in our department were analysed retrospectively (8 women and 29 men, mean age 62,32 ± 10,86 years, range 40 to 78 years). Eight patients underwent off-pump bypass.


Twenty-two patients were diabetic (%59.5), 24 patients had hypertension (64.9%), 14 patients had hyperlipidemia (%37.8), 27 patients had a history of smoking (%73), two patients had chronic obstructive pulmonary disease (%5.4), six patients had peripheral artery disease (%16.2), one patient had a history of cerebrovascular accident (%2.7), one patient had a history of intracardiac defibrillator implantation (%2.7), three patients had percutaneous coronary intervention (%8.1).


Risk factors should be evaluated for the short and mid-term outcomes of patients with low EF undergoing CABG.
