Surgical outcomes of isolated coronary artery bypass grafting for acute and chronic coronary artery syndromes: based on Sulaimani cardiac registry

Background: The leading cause of death worldwide is coronary artery disease. Globally, coronary artery bypass grafting is among the most frequently carried out procedures. A number of factors, including but not limited to gender, age, comorbidities, duration of cardiopulmonary bypass time, and surgical urgency, influence the short-term mortality following Coronary Artery Bypass Grafting (CABG). Patients and methods: 220 consecutive CABG patients who underwent surgery between January 2022 and December 2022 were included in a prospective comparative analysis carried out at a single location. Convenience sampling was the approach used to obtain the data. Results: 60.4 ± 9.4 CI (95% 36–81) years was the average age of all patients. Just 32.3% of participants were smokers. In 15.5% of cases, patients had emergent surgery. There was no discernible correlation between the pre-operative and intraoperative composite score and early morbidities. However, emergency surgery had a significant value of ( P = 0.018) in relation to hospital mortality. Additionally, there was a strong correlation between in-hospital mortality and the cross-clamp time and CPB ( P = 0.000 and 0.05). Our subjects underwent survival analysis using Kaplan–Meier, with a mean follow-up duration of 50.43 ± 12.36 weeks. Eleven deaths were reported in the first year’s results. Conclusion: Survival is significantly impacted by CABG. If at all possible, it is preferable to improve a patient’s condition before surgery in order to reduce mortality. The patient’s chance of survival is impacted by complications including stroke and extended intubation. In some patients, re-examination should be allowed with a low barrier because the alternative might be fatal.
