RESUMEN
INTRODUCTION: This retrospective observational study aimed to evaluate the feasibility and effectiveness of complete revascularization coronary artery bypass grafting (CABG) in patients with multi-vessel disease (MVD)-CAD and declined renal functions, addressing the knowledge gap regarding optimal treatment strategies and outcomes in this specific patient population. METHODS: Between 2020 and 2022, a total of 58 patients underwent on-pump coronary artery bypass grafting surgery for complete myocardial revascularization in this study. To assess overall survival, Kaplan-Meier with the log-rank test was conducted for statistical analysis. RESULTS: The mean age of cohort was 60.7. The findings showed a high prevalence of medical conditions such as hypertension (50.0%), diabetes (50.0%), and anaemia (41.4%) among the participants. Intraoperatively, low cardiac output syndrome was reported in 5.2% of cases, while perioperative outcomes indicated a need for transfusions in 53.5% of cases and an in-hospital mortality rate of 3.4%. At the 12-month follow-up, no redo revascularization or renal replacement therapy was required, but cardiac mortality was 5.2% and all-cause mortality was 6.9%. CONCLUSIONS: The study concluded that complete revascularization is safe for these patients and highlights the potential benefits, emphasizing the need for further research in optimizing revascularization techniques for this population.

INTRODUCTION: The feasibility and standardization of coronary artery bypass grafting (CABG) in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) and unstable angina (UA) remain topics of ongoing debate. In this study, feasibility and early-term outcomes of CABG in patients with NSTE-ACS and UA were discussed. METHODS: This study enrolled 79 patients who underwent on-pump CABG with complete revascularization between January 2020 and May 2022. the survival rates analyzed using Kaplan Meier test with log rank test. The p value of statistical significance was taken as below 0.05. RESULTS: Preoperatively, the patients had a mean age of 60.9 years and a BMI of 28.0. The medical history included hypertension (50.6%), peripheral arterial disease and atrial fibrillation (12.7%), and other comorbidities such as COPD (22.8%) and type 2 diabetes mellitus (44.3%). Intraoperatively, the mean distal anastomosis count was 3.4, with average cardiopulmonary bypass and aortic cross-clamp times of 84.0 and 49.0â min, respectively. Early-term outcomes revealed low rates of mortality (2.5%) and complications such as myocardial infarction (1.3%), acute kidney injury (5.1%) and transient ischemic attack (5.1%). Post-discharge outcomes demonstrated low cardiac and all-cause mortality rates (2.5% and 3.8%, respectively) and a high overall survival rate (93.7%) at 12-month follow-up. CONCLUSION: This study demonstrated the feasibility and positive outcomes of complete surgical revascularization in patients with UA and NSTE-ACS. It showed no graft occlusion or stroke, low complication rates and promising survival outcomes. Further research is needed for confirmation and to establish the procedure's efficacy and safety in this patient population.
