Abstract

Objectives: To assess the improvement in left ventricular ejection fraction (LVEF) after Coronary artery bypass grafting (CABG) among patients with severe LV dysfunction.

Methodology: This Quasi experimental study was conducted at Punjab Institute of Cardiology from January to June 2021. One hundred and thirty four patients of severe LV dysfunction with coronary anatomy suitable for CABG were included in the study.  Assessment of LVEF was carried out with echocardiography at baseline. All patients underwent CABG under general anaesthesia and were followed-up on 15th day with repeat echocardiography. Pre-CABG and post-CABG EFs were compared and mean changes in EFs were checked for potential effect modifications with gender, diabetes, CAD duration, age and body weight.

Results: The mean LVEFs before and after surgery were 23.63 ± 1.17% and 32.11 ± 1.98% respectively. Mean improvement in LVEF after CABG was 8.5 ± 2.7 % (p < 0.001, 95% CI for difference 8.0 – 8.9) and did not different significantly according to gender, diabetes, CAD duration, age and body weight (P = 0.592, 0.167, 0.506, 0.138 and 0.458 respectively).

Conclusion: Patients of CAD who underwent CABG had improved post-operative LVEFs independent of evaluated potential effect modifiers.
