Improvement of left ventricular function after CABG in patients with poor left ventricular function.

Objective: To determine frequency of improvement of left ventricular ejection fraction (LVEF) after CABG surgery in patients with poor left ventricular function preoperatively. Study Design: Cross-sectional study. Setting: Department of Cardiac Surgery, Faisalabad Institute of Cardiology, Faisalabad. Period: 10th November 2022 to 9th October 2023. Methods: Patients with poor Left ventricular function (LVEF) determined by echocardiography or angiography were confirmed by Multigated Acquisition (MUGA) scan pre operatively. They were admitted in cardiac surgery ward, where baseline investigations were done for planned CABG. After surgery they were followed up and there LVEF was determined by repeat MUGA scan at 3 months. Results: Frequency of improvement of left ventricular function (LVEF) after CABG in patients with poor left ventricular function preoperatively was recorded in 13.85%(n=9). Conclusion: Frequency of improvement of left ventricular function (LVEF) was not very higher after CABG in patients with pre operative poor left ventricular function. However, our results need validation through multicenter trials.
