Objective: Despite increasing recognition of the benefits of off-pump coronary artery bypass grafting (CABG), concerns persist regarding its impact on long-term mortality and freedom from reintervention. In this study, we assessed the impact of off-pump CABG on long-term outcomes.
Methods: From January 2002 to December 2002, a total of 307 consecutive patients who underwent isolated multivessel off-pump CABG at our institution were compared with a control group of 397 patients who underwent multivessel on-pump CABG during the same period. Perioperative data were prospectively collected and compared. In addition, univariate and risk-adjusted comparisons between the two groups were performed at 10 years.
Results: After adjusting for clinical covariates, off-pump CABG did not emerge as a significant independent predictor of long-term mortality [hazard ratio (HR), 0.91; 95% confidence interval (CI), 0.70-1.12], readmission to hospital for cardiac cause (HR, 0.96; 95% CI, 0.78-1.10), or the need for reintervention (HR, 0.93; 95% CI, 0.87-1.05).
Conclusions: At long-term follow-up, off-pump CABG remains a safe and effective myocardial revascularization strategy with no adverse impact on survival or freedom from reintervention.

90-day mortality risk related to postoperative potassium levels in patients undergoing coronary bypass surgery.

Aims: While electrolyte depletion is known to occur during coronary artery bypass grafting (CABG) with extracorporeal circulation, little is known about the frequency of potassium disturbances following either on- or off-pump CABG and its association with mortality. We examined the frequency of potassium disturbances and the association of plasma potassium with mortality risk in patients following CABG.
Methods And Results: From Danish National Registries, we identified 6123 adult patients (≥18 years old) undergoing first-time CABG, and who had a registered potassium measurement within 14 days before and 7 days after their surgery between 1995 and 2018.
A Rare Case of Early Left Ventricular Thrombus Development After Off-Pump Coronary Artery Bypass Grafting for Unstable Angina Pectoris With Reduced Left Ventricular Ejection Fraction.

Left ventricular (LV) thrombus is a serious complication of myocardial infarction (MI) that can lead to a fetal systemic embolism. Although coronary artery bypass graft surgery (CABG) after MI is widely performed, to our knowledge, there are no reports of LV thrombus in the early postoperative period. Here, we report a rare case of a 70-year-old man who underwent off-pump coronary artery bypass grafting (OPCAB) for unstable angina pectoris with reduced left ventricular ejection fraction (LVEF).

- This study examines the role of serum uric acid (SUA) levels in patients undergoing off-pump coronary artery bypass (OCABG) surgery, focusing on their impact on postoperative complications like acute kidney injury (AKI).
- The research involved 144 patients and found that 20% experienced AKI, with higher preoperative SUA levels significantly linked to increased risk (OR: 2.04).
- Additionally, elevated SUA levels correlated with longer hospital stays and a higher mortality rate (up to 13% in high SUA patients), indicating that SUA is a crucial predictor for postoperative outcomes.
Off-Pump Coronary Artery Bypass Grafting is Overutilized.

Off-pump coronary artery bypass grafting (CABG), developed to avoid the potential complications of cardiopulmonary bypass, remains a subject of debate. Studies have demonstrated that off-pump CABG is associated with higher rates of incomplete revascularization, inferior graft patency, and increased reintervention rates compared to on-pump CABG, leading to worse outcomes. The theoretical neuroprotective and renal-protective benefits associated with off-pump CABG have not been definitively proven, with stroke and renal failure rates similar to those of on-pump CABG in both short- and long-term follow-up.

Introduction: Many studies have shown that coronary artery bypass grafting (CABG) increases the survival rate of patients, but the effect of bypass grafting on cardiac function is still a matter of debate.
Objective: The objective of our study was to determine: a. To what extent can the change in coronary sinus flow be used as an intraoperative criterion for the assessment of adequate revascularization.
