Insights
Coronary artery bypass grafting (CABG) offers lower long-term mortality for end-stage renal disease (ESRD) patients compared to percutaneous coronary intervention (PCI). However, CABG increases early mortality risk for both chronic kidney disease (CKD) and ESRD patients.
Area of Science:
- Cardiovascular Medicine
- Nephrology
- Interventional Cardiology
Background:
- Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are associated with increased cardiovascular risk.
- Optimal revascularization strategies for patients with CKD and ESRD remain debated.
Approach:
- A meta-analysis of 31 observational studies involving 74,805 patients was conducted.
- Studies compared coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) for revascularization in CKD and ESRD patients.
Key Points:
- CABG was associated with higher early mortality in both CKD and ESRD patients compared to PCI.
- For ESRD patients, CABG demonstrated significantly lower all-cause and cardiac mortality.
- PCI was associated with a higher long-term risk of repeat revascularization and myocardial infarction in both CKD and ESRD patients.
Conclusions:
- CABG may be a preferred strategy for long-term outcomes in ESRD patients, despite increased early mortality risk.
- Further adequately powered, prospective randomized controlled trials (RCTs) are necessary to establish the optimal revascularization strategy for CKD and ESRD patients.
Objectives:
To compare coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for revascularising coronary arteries in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD). CKD is described as a continuous decrease in the glomerular filtration rate or abnormalities in kidney structure or function.
Methods:
PubMed, Cochrane Library and Embase databases were searched for studies on the revascularisation of coronary arteries in patients with CKD and ESRD.
Results:
Since no randomised controlled trials (RCTs) have addressed this issue so far, 31 observational studies involving 74 805 patients were included in this meta-analysis. Compared with PCI, patients undergoing CABG have significantly higher early mortality (CKD: RR = 1.62, 95% CI: 1.17-2.25, pheterogeneity = 0.476, I2 = 0; ESRD: RR = 1.99, 95% CI: 1.46-2.71, pheterogeneity = 0.001, I2 = 66.9%). Patients with ESRD undergoing CABG have significantly lower all-cause mortality (RR = 0.95, 95% CI: 0.93-0.96, pheterogeneity < 0.001, I2 = 82.9%) and cardiac mortality (RR = 0.73, 95% CI: 0.58-0.92, pheterogeneity = 0.908, I2 = 0). The long-term risk of repeat revascularisation (CKD: RR = 0.24, 95% CI: 0.19-0.30, pheterogeneity = 0.489, I2 = 0; ESRD: RR = 0.23, 95% CI: 0.15-0.34, pheterogeneity = 0.012, I2 = 54.4%) and myocardial infarction (CKD: RR = .57, 95% CI: 0.38-0.85, pheterogeneity = 0.025, I2 = 49.9%; ESRD: RR = 0.42, 95% CI: 0.40-0.44, pheterogeneity = 0.49, I2 = 0) remained significantly higher in the PCI group.
Conclusions:
Patients with ESRD, but not CKD, who underwent CABG had significantly lower all-cause mortality and cardiac mortality. However, CABG was associated with an increased risk of early mortality in patients with CKD or ESRD. Adequately powered, contemporary, prospective RCTs are needed to define the optimal revascularisation strategy for patients with CKD and ESRD.
