Insights

Complete revascularization via coronary artery bypass grafting (CABG) is feasible and safe for patients with multi-vessel disease (MVD)-CAD and poor kidney function. This approach shows promising outcomes, warranting further investigation into optimal techniques.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Nephrology

Background:

  • Multi-vessel disease (MVD)-coronary artery disease (CAD) often presents challenges in patients with declining renal function.
  • Optimal revascularization strategies for this specific high-risk population remain incompletely understood.
  • Coronary artery bypass grafting (CABG) is a common treatment, but its effectiveness in renally impaired patients requires evaluation.

Purpose of the Study:

  • To assess the feasibility and effectiveness of complete revascularization using CABG.
  • To evaluate outcomes in patients with MVD-CAD and compromised renal function.
  • To address the knowledge gap concerning treatment strategies and survival in this cohort.

Main Methods:

  • Retrospective observational study design.
  • Inclusion of 58 patients undergoing on-pump CABG for complete myocardial revascularization between 2020 and 2022.
  • Statistical analysis using Kaplan-Meier curves and the log-rank test for overall survival.

Main Results:

  • The cohort (mean age 60.7) had high comorbidity rates: hypertension (50.0%), diabetes (50.0%), and anemia (41.4%).
  • Perioperative outcomes included 5.2% low cardiac output syndrome, 53.5% transfusion rates, and 3.4% in-hospital mortality.
  • At 12-month follow-up, cardiac mortality was 5.2% and all-cause mortality was 6.9%, with no need for renal replacement therapy or redo revascularization.

Conclusions:

  • Complete revascularization via CABG is a safe and feasible option for patients with MVD-CAD and declining renal function.
  • The study suggests potential benefits of this approach in a high-risk population.
  • Further research is recommended to optimize revascularization techniques for improved outcomes in this patient group.
