THE LONG-TERM RESULTS OF CORONARY ARTERY BYPASS GRAFTING( CABG) FOR PATIENTS WITH LEFT VENTRICULAR DYSFUNCTION.
The cornerstone of treatment for patients with reduced left ventricular function and ischemic cardiomyopathy is guideline driven medical therapy for all patients and implantable device therapy for appropriately selected cases  . Despite the fact that coronary artery bypass grafting is the standard of care for patients with multivessels disease and/or left main stem stenosis, the role of surgical revascularization in this highest-risk patients remains controversial due to the high perioperative risks and lack of proven benefits in the long-term  . The scope of this study is to assess the perioperative morbidity and mortality and the long-term results in this group of patients.
Material and methods
The records of patients who underwent an isolated coronary artery bypass grafting surgery at our institute between 2008 and 2012 were reviewed. All patients with preoperative left ventricle dysfunction, ejection fraction (EF) under 40%, including emergency and urgent cases were included.
Mean age was 69.0±10.3 and the majority (86.7%) were male. Thirtythree patients (36.7%) had a history of congestistive heart failure. Twentythree patients (25.6%) had a history of prior PCI. Preoperative ejection fraction was in average 31.6± 6.2%.
