Coronary artery bypass grafting in patients with left ventricular dysfunction presented at Peshawar Institute of Cardiology..
Professional Med J Jan ;30(7):865-70.

Objective: To determine the outcomes of patients undergoing coronary artery bypass grafting having reduced ejection fraction. Study Design: Retrospective Observational study. Setting: Peshawar Institute of Cardiology. Period: August 2021 to May 2022. Material & Methods: We included a number of (n=120) patients who were undergone for CABG with mild to severe left ventricular dysfunction. Data was extracted from electronic medical record (EMR) and entered in SPSS version 25.00. Ethical approval was taken from hospital ethical review board committee. Results: Mean age of patients were (57.40±9.311), mean cross clamp time (71.88±26.765) mean bypass time (109.77±43.763), mean hospital stay (4.63±.879) and mean ICU stays (41.60±16.385). 46.7% patients were in CCS III, 41.7% CCS II and 6.7% in CCS IV. In NYHA class 43% were with NYHA II & III and 6.7% with NYHA IV. 21.7% patients were with mild LV dysfunction, 43.3% with moderate and 35% severe LV dysfunction. Association of left ventricular dysfunction towards post-operative outcomes and clinical history has significant association at p <0.05. Conclusion: Coronary artery bypasses grafting extensively used for the treatment of patients with left ventricular dysfunction. Although medical management are also widely use and acceptable for moderate to severe LV dysfunction. Our study suggested that left ventricular dysfunction are strongly associated with post-operative out comes and clinical presentations.
