Role of Various Pre Operative Risk Factors in Outcome Following Coronary Artery Bypass Graft: An Institutional Based Study

Abstract

Background: Coronary Artery Bypass Graft (CABG) is done in patient with Coronary Artery Disease (CAD) with Normal or decreased Left Ventricular Ejection Fraction (LVEF). Most of the patient with CAD presents with NYHA class II or III.

Methods: It’s an analytical study of retrospectively collected data of all patients who underwent CABG for CAD. Data were collected over the period of about 30 months at Nobel Medical College and Teaching Hospital.

Results: There were a total of 54 patients in our study. There was male 38 (72%) predominance. There were 49 (92.5%) cases having BMI <30 kg/m². However only 2 (4%) had COAD, 23 (43%) had DM II, 9 (17%) had abnormal thyroid function, 6 (11%) were dyslipidemic and 1 (2 %) had a prior history of CVA. There were 23 (4%) of patients who had history of MI in past and around 45 (85%) had Triple Vessel Disease (TVD).

Conclusion: Among all the pre-operative risk factors HTN and H/O MI had a significant association in improvement in LVEF, similarly thyroid status had a strong association with improvement in NYHA
