Abstract
PURPOSE Little is known about the outcomes of patients with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI) who undergo coronary artery bypass grafting (CABG) in the current percutaneous coronary intervention (PCI) era. METHODS We analyzed 25120 acute myocardial infarction (AMI) patients hospitalized between January 2011 and December 2016. In-hospital outcomes were compared between patients who underwent CABG during hospitalization and those who did not undergo CABG in the STEMI group (n = 19428) and NSTEMI group (n = 5692). RESULTS Overall, CABG was performed in 2.3% of patients, while 90.0% of registered patients underwent primary PCI. In both the STEMI and NSTEMI groups, patients who underwent CABG were more likely to have heart failure, cardiogenic shock, diabetes, left main trunk lesion, and multivessel disease than those who did not undergo CABG. In multivariable analysis, CABG was associated with lower all-cause mortality in both the STEMI group (adjusted odds ratio [OR] = 0.43, 95% confidence interval [CI] 0.26-0.72) and NSTEMI group (adjusted OR = 0.34, 95% CI 0.14-0.84). CONCLUSION AMI patients undergoing CABG were more likely to have high-risk characteristics than those who did not undergo CABG. However, after adjusting for baseline differences, CABG was associated with lower in-hospital mortality in both the STEMI and NSTEMI groups.

Abstract
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 49.0 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.

Abstract
Objectives Off-pump coronary artery bypass grafting (OPCAB) surgery is controversial in part because of the surgeon's experience, which correlates with how the surgeon is trained. Because the training model of OPCAB is not uniform, the quality control in the training process seems to be more important and needs to be further discussed. Methods Nine surgeons accepted and completed an OPCAB training course at a single center to become independent surgeons. This training program is characterized by 6 progressive levels supervised by experienced trainers. In total, 2307 consecutive cases of OPCAB performed by the 9 trainee surgeons were analyzed for monitoring and evaluation in quality control. The funnel plots and cumulative summation (CUSUM) analysis method were used to evaluate the performance of each surgeon. Results The mortality and complications of each surgeon were all within the 95% confidence interval of funnel plots. The CUSUM learning curves of first 3 trainees was analyzed and showed that the trainees need to complete approximately 65 cases to cross the CUSUM learning curve to reach a steady state. Conclusions The trainees can directly receive the OPCAB training course under the guidance of experienced surgeons with a rigorous schedule. It is feasible to perform quality control by funnel plots and CUSUM method in OPCAB surgery to ensure the safety of the training course.

Abstract
BACKGROUND Coronary artery bypass grafting (CABG) in the setting of an acute coronary syndrome is a high-risk procedure, and the best strategy for myocardial revascularisation remains debated. This study compares the 30-day mortality benefit of on-pump CABG (ONCAB), off-pump CABG (OPCAB), and on-pump beating heart CABG (OnBHCAB) strategies. METHODS A systematic search of three electronic databases was conducted for studies comparing ONCAB with OPCAB or OnBHCAB in patients with acute coronary syndrome (ACS). The primary outcome, 30-day mortality, was compared using a Bayesian hierarchical network meta-analysis (NMA). A random effects consistency model was applied, and direct and indirect comparisons were made to determine the relative effectiveness of each strategy on postoperative outcomes. RESULTS One randomised controlled trial and eighteen observational studies fulfilling the inclusion criteria were identified. A total of 4320, 5559, and 1962 patients underwent ONCAB, OPCAB, and OnBHCAB respectively. NMA showed that OPCAB had the highest probability of ranking as the most effective treatment in terms of 30-day mortality (odds ratio [OR], 0.50; 95% credible interval [CrI], 0.23-1.00), followed by OnBHCAB (OR, 0.62; 95% CrI, 0.20-1.57), however the 95% CrI crossed or included unity. A subgroup NMA of nine studies assessing only acute myocardial infarction (AMI) patients demonstrated a 72% reduction in likelihood of 30-day mortality after OPCAB (CrI, 0.07-0.83). No significant increase in rate of stroke, renal dysfunction or length of intensive care unit stay was found for either strategy. CONCLUSIONS Although no single best surgical revascularisation approach in ACS patients was identified, the significant mortality benefit with OPCAB seen with AMI suggests high acuity patients may benefit most from avoiding further myocardial injury associated with cardiopulmonary bypass and cardioplegic arrest.

Coronary Artery Bypass Grafting in Patients with Chronic Kidney Disease: Chronic Kidney Disease Has an Independent Adverse Effect on the Long-Term Outcome of Coronary Artery Bypass Grafting. BIOMED RESEARCH INTERNATIONAL 2022; 2022:4994970. [PMID: 35528157 PMCID: PMC9071893 DOI: 10.1155/2022/4994970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 03/19/2022] [Accepted: 04/02/2022] [Indexed: 11/18/2022]
Abstract
We examined short- and long-term outcomes of coronary artery bypass grafting (CABG) in patients with ischemic heart disease and the effect of renal function on these outcomes. We included 2783 patients who underwent primary elective CABG at a single institution between 2002 and 2020 (age: 67.6 ± 10.2 years; male: 2281 male). They were stratified based on their preoperative estimated glomerular filtration rate and underwent off-pump CABG (completion rate, 98.1%); 57.6% cases used bilateral internal thoracic arteries (BITA). In-hospital mortality rate was 1.0%. Logistic regression analysis revealed that low left ventricular function (<40%), but not chronic kidney disease (CKD) severity, was an independent predictive risk factor for postoperative hospital mortality. Significant differences existed in respiratory complications, infections, and hospitalization duration according to CKD severity. Deep sternal wound infection rate was 0.5%. The mean follow-up period was 7.1 (0–18.5) years. Estimated 10-year survival rates were negatively correlated with CKD severity; in the Cox hazard model, severe CKD was an independent predictor of long-term survival. We examined the relationship between preoperative and intraoperative factors and their effects on long-term survival using propensity score matching by dividing the renal function severity into G1–2 and G3–5. Renal function severity, age, and operative time were independent risk factors. No prognostic improvement was observed with BITA grafts; graft patency was superior in the right internal thoracic artery (52/52; 100%) than in the great saphenous vein (48/59; 81.4%) in G5. Post-CABG in-hospital mortality was unrelated to renal function, but CKD severity strongly influenced long-term survival. Operation time was an important predictor of long-term prognosis in patients with impaired renal function. Treatment plans, including graft and anastomosis-site selections, should be designed to shorten the operation time. In conclusion, using the right internal thoracic artery in CABG is more beneficial in patients with CKD and cardiovascular comorbidities.

Abstract
OBJECTIVES The aim of this was to analyse current outcomes in patients referred to coronary artery bypass grafting (CABG) for acute coronary syndromes (ACSs), including ST-elevation or non-ST-elevation ACS (non-ST-segment elevation myocardial infarction) or unstable angina. METHODS Patients (n = 2432) undergoing CABG for ACS between January 2010 and December 2017 were prospectively entered into a surgical myocardial infarction registry in North Rhine-Westphalia, Germany. Key end points were in-hospital all-cause mortality (IHM) and major adverse cardio-cerebral events (MACCE). Predictors for IHM and MACCE were analysed by multivariable logistic regression. RESULTS Patients (78% males) were referred for CABG for unstable angina (25%), non-ST-segment elevation myocardial infarction (50%), and ST-segment elevation myocardial infarction (25%). The mean patient age was 68 ± 11 years, logistic EuroSCORE was 19 ± 18% and three-vessel and left main stem diseases were diagnosed in 81% and 45% of patients, respectively. On-pump CABG with cardiac arrest or beating heart was performed in 92% and 2%, respectively, with only 6% off-pump surgery and 6% multiple arterial revascularization (3.1 ± 1.0 grafts, 93% left internal thoracic artery). Emergency CABG was performed in 23% of patients (42% in ST-segment elevation myocardial infarction; P < 0.001). The total IHM and MACCE rates were 8.1% and 17.5% and were highest in ST-segment elevation myocardial infarction patients with 12.6% and 28.5%, respectively (P < 0.001). Key predictors for IHM and MACCE were female gender, elevated troponin, left ventricular ejection fraction, inotropic support, logistic EuroSCORE, cardiopulmonary bypass and aortic clamp time and the need for emergency CABG. CONCLUSIONS Surgical myocardial revascularization in patients with ACS is still linked to substantial in-hospital mortality. Emergency CABG for patients with ACS was associated with poorer outcomes.

Abstract
Background Coronary artery bypass grafting for acute coronary syndrome complicated by cardiogenic shock (CS) is associated with a high mortality. This registry study aimed to distinguish between early surgical outcomes of CS patients with non–ST‐segment–elevation myocardial infarction (NSTEMI) and ST‐segment–elevation myocardial infarction (STEMI). Methods and Results Patients with NSTEMI (n=1218) or STEMI (n=618) referred for coronary artery bypass grafting were enrolled in a prospective multicenter registry between 2010 and 2017. CS was present in 227 NSTEMI (18.6%) and 243 STEMI patients (39.3%). Key clinical end points were in‐hospital mortality (IHM) and major adverse cardiocerebral events (MACCEs). Predictors for IHM and MACCEs were identified using multivariable logistic regression analysis. STEMI patients with CS were younger, had a lower prevalence of diabetes mellitus and multivessel disease, and exhibited higher myocardial injury (troponin 9±17 versus 3±6 ng/mL) before surgery compared with patients with NSTEMI (P<0.05). Emergency coronary artery bypass grafting was performed more often in STEMI (58%) versus NSTEMI (40%; P=0.002). On‐pump surgery with cardioplegia was the preferred surgical technique in CS. IHM and MACCE rates were 24% and 49% in STEMI patients with CS and were higher compared with NSTEMI (IHM 15% versus MACCE 34%; P<0.001). Predictors for IHM and MACCE in CS were a reduced ejection fraction and a higher European System for Cardiac Operative Risk Evaluation score. Conclusions Surgical revascularization in NSTEMI and STEMI patients with CS is associated with a substantial but not prohibitive IHM and MACCE rate. Worse early outcomes were found for patients with STEMI complicated by CS compared with NSTEMI patients.

Abstract
As per the findings of the SYNTAX Trial, it has been established that coronary artery bypass grafting (CABG) affords the best long-term results in patients with multivessel disease. However, it is still a point of contention whether 'off-pump' CABG (OPCAB) (on cardiopulmonary bypass) is better. Many studies appear to establish the superiority of one or the other. But there is still no well-planned multi-centre randomised controlled trial looking into all aspects of the issue that can, once and for all, put the controversy to rest. But as long as one is able to give the patient a good result, does it really matter whether the procedure is done off or on pump? This article looks at the available evidence with regard to various parameters comparing OPCAB and conventional CABG in an attempt to answer the question, if at all, it is a question!
