Coronary artery bypass graft surgery versus stenting for patients with chronic kidney disease and complex coronary artery disease: a systematic review and meta-analysis.

ABSTRACT:

Background

The relative role of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) with stent implantation in patients with chronic kidney disease (CKD) and complex coronary artery disease (CAD) remains debatable due to the lack of randomized controlled trials (RCTs). We therefore performed this meta-analysis to compare the outcomes of the two strategies in CKD patients with multivessel and/or left main disease.

Methods

Electronic databases including PubMed, EMBASE and Cochrane Library were comprehensively searched to identify the eligible subgroup analysis of RCTs and propensity-matched registries. The primary endpoint was all-cause mortality during the longest follow-up.

Results

Five subgroup analyses of RCTs and six propensity-matched registries involving 26,441 patients were analyzed. Overall, the strategy of CABG was associated with lower risks of long-term mortality [odds ratio (OR) 0.83, 95% confidence interval (CI) 0.74-0.93], myocardial infarction (OR, 0.41; 95% CI, 0.27-0.62), and repeat revascularization (OR, 0.25; 95% CI, 0.16-0.39) compared with PCI in CKD patients with complex CAD. However, CABG was slightly associated with higher risk of stroke than PCI (OR, 1.33; 95% CI, 1.00-1.77). Nonetheless, the higher stroke risk in the CABG group no longer existed during long-term follow-up (OR, 0.92; 95% CI, 0.37-2.25) (>3 years).

Conclusion

This meta-analysis supports the current guideline advising CABG for patients with CKD and complex CAD. At the expense of slightly increased risk of stroke, CABG reduces the incidences of long-term all-cause death, myocardial infarction and repeat revascularization compared with PCI.

Project description:BackgroundRandomized trials of percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) routinely exclude patients with chronic kidney disease (CKD).ObjectivesThis study evaluated outcomes of PCI versus CABG in patients with CKD.MethodsPatients with CKD who underwent PCI using everolimus-eluting stents were propensity-score matched to patients who underwent isolated CABG for multivessel coronary disease in New York. The primary outcome was all-cause mortality. Secondary outcomes were myocardial infarction (MI), stroke, and repeat revascularization.ResultsOf 11,305 patients with CKD, 5,920 patients were propensity-score matched. In the short term, PCI was associated with a lower risk of death (hazard ratio [HR]: 0.55; 95% confidence interval [CI]: 0.35 to 0.87), stroke (HR: 0.22; 95% CI: 0.12 to 0.42), and repeat revascularization (HR: 0.48; 95% CI: 0.23 to 0.98) compared with CABG. In the longer term, PCI was associated with a similar risk of death (HR: 1.07; 95% CI: 0.92 to 1.24), higher risk of MI (HR: 1.76; 95% CI: 1.40 to 2.23), a lower risk of stroke (HR: 0.56; 95% CI: 0.41 to 0.76), and a higher risk of repeat revascularization (HR: 2.42; 95% CI: 2.05 to 2.85). In the subgroup with complete revascularization with PCI, the increased risk of MI was no longer statistically significant (HR: 1.18; 95% CI: 0.67 to 2.09). In the 243 matched pairs of patients with end-stage renal disease on hemodialysis, PCI was associated with significantly higher risk of death (HR: 2.02; 95% CI: 1.40 to 2.93) and repeat revascularization (HR: 2.44; 95% CI: 1.50 to 3.96) compared with CABG.ConclusionsIn patients with CKD, CABG is associated with higher short-term risk of death, stroke, and repeat revascularization, whereas PCI with everolimus-eluting stents is associated with a higher long-term risk of repeat revascularization and perhaps MI, with no long-term mortality difference. In the subgroup on dialysis, the results favored CABG over PCI.

Project description:BackgroundIn patients with diabetes mellitus and multivessel disease, coronary artery bypass graft surgery and percutaneous coronary intervention are treatment options. However, there is paucity of data comparing coronary artery bypass graft surgery against newer generation stents.Methods and resultsPatients included in the New York State registries who had diabetes mellitus and underwent isolated coronary artery bypass graft surgery or percutaneous coronary intervention with everolimus eluting stent (EES) for multivessel disease were included. Propensity score matching was used to assemble a cohort with similar baseline characteristics. The primary outcome was all-cause mortality. Secondary outcomes were myocardial infarction (MI), stroke, and repeat revascularization. Short-term (within 30 days) and long-term outcomes were evaluated. Among 16,089 patients with diabetes mellitus and multivessel disease, 8096 patients with similar propensity scores were included. At short-term, EES was associated with a lower risk of death (hazard ratio [HR] =0.58; 95% confidence interval [CI], 0.34-0.98; P=0.04) and stroke (HR=0.14; 95% CI, 0.06-0.30; P<0.0001) but higher risk of MI (HR=2.44; 95% CI, 1.13-5.31; P=0.02). At long-term, EES was associated with a similar risk of death (425 [10.50%] versus 414 [10.23%] events; HR=1.12; 95% CI, 0.96-1.30; P=0.16), a lower risk of stroke (118 [2.92%] versus 157 [3.88%] events; HR=0.76; 95% CI, 0.58-0.99; P=0.04) but a higher risk of MI (260 [6.42%] versus 166 [4.10%] events; HR=1.64; 95% CI, 1.32-2.04; P<0.0001) and repeat revascularization (889 [21.96%] versus 421 [10.40%] events; HR=2.42; 95% CI, 2.12-2.76; P<0.0001). The higher risk of MI was not seen in the subgroup of EES patients who underwent complete revascularization (HR=1.37; 95% CI, 0.76-2.47; P=0.30).ConclusionsIn patients with diabetes mellitus and multivessel disease, EES was associated with lower upfront risk of death and stroke when compared with coronary artery bypass graft surgery. However, at long-term, EES was associated with similar risk of death, a higher risk of MI (in those with incomplete revascularization), and repeat revascularization but a lower risk of stroke.
