Abstract

Objective: To describe the early outcomes including clinical and subclinical characteristics before and during surgery, postoperative results, general complications, and early in-hospital mortality. Subject and method: Patients indicated for coronary artery bypass grafting (CABG) at Thu Duc City Hospital from 2018 to 2023. Study method: A retrospective, descriptive case series without control group. Result: The study included 34 cases with an average age of 66.7 ± 7.2 years, with males accounting for 55.9%, and those under 70 years old making up 67.6%. Common medical conditions and risk factors included hypertension at 79.4%, diabetes at 55.9%, and dyslipidemia at 23.5%. The preoperative left ventricular function had an average ejection fraction (EF) of 58.29 ± 9.14%. Three-vessel coronary artery disease was recorded in 70.6% of cases, with left main disease accompanying in about 26.5%. The average surgery duration was 291.8 ± 88.0 minutes, with the shortest being 200 minutes and the longest 560 minutes. The average number of grafts performed was 2.7 ± 0.5 grafts. About 67.6% of the cases utilized 2 internal thoracic arteries and 1 great saphenous vein for grafting. The average duration of mechanical ventilation, ICU stay, and postoperative hospital stay were 19.1 ± 27.3 hours (with prolonged mechanical ventilation in 11.8% of cases), 4.2 ± 1.9 days, and 13 ± 4.3 days, respectively. There were a low mortality rate of 2.94% and significant clinical improvement in angina symptoms 30 days post-operation. A history of chronic kidney disease before surgery influenced the incidence of acute kidney injury after surgery. Conclusion: Coronary artery bypass surgery at Thu Duc City Hospital has initially achieved desirable outcomes with a low mortality rate.
