Coronary artery bypass grafting in patients with severe left ventricular dysfunction: early outcomes.
J Cardiovascular Dis Jan ;11(3):74-7.

OBJECTIVE:To study the in-hospital outcome of coronary artery bypass grafting (CABG) in patients with severe left ventricular dysfunction at a high volume center. MATERIAL AND METHODS: An observational study was conducted from March 2012 to March 2013 in cardiac surgery unit at Punjab Institute of Cardiology, Lahore. Eighty consecutive patients who had undergone on-pump CABG, operated by the same surgical team, with a severe LV dysfunction (EF<35%), were included in the study. Preoperative, intraoperative and postoperative variables were recorded and analyzed using Statistical Package for Social Sciences version 20.0 to find the in-hospital outcome. RESULTS:Total number of patients included was 80 (n=80). Mean age was 61.80±11.47 years. Patients with angina Canadian Cardiovascular Society Class III or IV were 32 (40%). Eight patients (10%) had left main coronary artery disease. Emergency CABG was performed in 8 (10%) patients. Mean postoperative hospital stay was 8.32±2.45 days. Acute kidney injury was observed in 4(6%) patients post-operatively. Five (7%) cases went into post operative exploration for hemorrhage and three (4%) patients had stroke after CABG. In-hospital mortality was recorded in 3 (4%) patients out of eighty cases. CONCLUSION: CABG in patients with severe left ventricular dysfunction can be performed with acceptable mortality and morbidity
