Abstract
Objective:To determine the patterns of per-operative parameters and early outcomes of patients that underwent CABG surgery during a four-year period.Methods:This is a cross-sectional descriptive study conducted in a tertiary care of hospital from November 2020 to January 2021. All the patients that underwent the isolated coronary artery bypass grafting (CABG) procedure were included in the study from June 2017 till June 2020. Data was collected on a data extraction form and stored in SPSS format which was analyzed for qualitative statistics keeping p<0.05 as significant. All the results were represented in the form of tables.Results:A total of 1,613 patients were operated upon for Coronary Artery Bypass Grafting (CABG) procedure during the study period with 1,222 (75.8%) males and 391 (24.2%) females. Dyslipidemia (71.8%) was the most common risk factor. The average perfusion time decreased only slightly (~1 minute) from 96.01 minutes to 95.07 minutes (2017 to 2020). This change however was not significant (p=0.301). The rate of Left Internal Mammary Artery (LIMA) use stayed relatively stable over the 4-year period fluctuating between 88.7% and 92.9% (p=0.360). The average initial ICU stay (in hours), drain at 12 hours and 24 hours stays almost the same. The rate of mortality peaked in 2018 (4.76%) and subsequently fell to 3.57% by 2020.Conclusion:More males underwent CABG surgery at this tertiary care hospital and the overall complication rate and per-operative parameters improved over the years. The non-risk stratified mortality in this study was found to be higher than developed nations.

Summary
Coronary Artery Bypass Grafting (CABG) is a common surgical procedure, representing annual volumes of approximately 200,000 cases in the United States and an average incidence rate of 62 per 100,000 inhabitants in Western European countries.[1] People with severe Coronary artery disease undergo CABG in order to improve blood flow to the heart as it is one of the most effective treatment against blocked coronary arteries and the complications the blockage may cause. This management plan carries a per-operative mortality of approximately 2% while other complications range between 5% and 7%.2. This procedure reduces the mortality in patient with severe coronary artery disease.[3]
