Abstract

Objectives: Evaluating early outcome of coronary artery bypass grafting (CABG) in isolated coronary artery disease (CAD) patients with left ventricular dysfunction. Patients and methods: Retrospective case series in patients with CAD and LVEF ≤ 40% undergoing CABG in Cho Ray hospital from January 2023 to June 2024. Results: 84 patients were included in study, the mean age was 60.1 ± 9.7; 70.2% were male and 52.4% of patients had normal BMI. Common comorbidities and risk factors were hypertension 73.8%; dyslipidemia 66.7%; history of myocardial infarction 54.8% and smoking 52.4%. Three-vessels disease accounted for 83.3% and left main disease accounted for 39.3%. Mean operative time was 265.0 ± 55.9 minutes. Average number of grafts was 3.9 ± 1.1. Median mechanical ventilation time was 15.8 hours. Median length of stay in intensive care and median length of stay in hospital were 5 days and 28 days, respectively. In-hospital mortality was 7.1%. Factors related to mortality were history of chornic lung disease, intraoperative blood loss, and cardiogenic shock. Conclusion: CABG in isolated coronary artery disease patients with left ventricular systolic dysfunction had shown a favorable early results and acceptable risks
