Meta-analysis of clinical adverse events after CABG vs. PCI in patients with chronic kidney disease and coronary artery disease

Abstract

Abstract Aim To investigate the efficacy and postoperative clinical adverse events of coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) for chronic kidney disease (CKD) study participants combined with coronary artery disease (CAD). Methods All randomized controlled trials (RCTs) that focus on the therapeutic effect evaluation of CABG and PCI and their effect on postoperative clinical adverse events as well as main adverse cardiovascular and cerebrovascular events (MACCEs) in CKD study participants with CAD were screened from the following databases, including CNKI, CBM, Wan Fang, VIP, Embase, PubMed, as well as Cochrane library clinical controlled trials. The study was conducted under the PRISMA 2020 criteria. Data were extracted, and quality control was evaluated from the modified Jadad rating scale. Meta-analysis was then undertaken through STATA 16.0 software. Results A total of 5 RCTs were obtained, including 1198 patients. Study participants were subdivided into two groups, including the PCI group (n = 604) and the CABG group (n = 594). Meta-analysis of clinical adverse events results showed that the long-term survival results of CAD patients with CKD who underwent PCI were worsened compared to CABG, such as long-term MACCEs (RR = 1.59, 95%CI: 1.04–2.43) and the long-term repeated revascularization (RR = 2.48, 95%CI: 1.76–3.49). Also, cardiac death (RR = 1.68, 95%CI:1.04–2.71), as well as cerebrovascular accident (RR = 1.74, 95%CI:1.04–2.90) in CABG group was significantly lower than that in PCI group. Conclusion This meta-analysis showed that CABG provided a better therapeutic effect than PCI in CKD patients with CAD when considering long-term prognosis. However, more prospective RCTs are needed to define the proper revascularization strategy for CAD patients with CKD.
