RESUMO
Background: Revascularization of the coronary arteries is associated with better short term and long term prognosis in patients having multivessel coronary artery disease (MV-CAD) and chronic kidney disease (CKD). However, whether revascularization using coronary artery bypass grafting (CABG) surgery or percutaneous coronary intervention (PCI) using drug eluting stents (DES) is better remains unknown. Objectives: To compare the outcomes of revascularization by multi-vessel PCI using DES versus revascularization by CABG in patients with CKD having multivessel CAD, regarding in-hospital and one-year major adverse cardiovascular and cerebrovascular events (MACCE). Methods: This was a retrospective analysis of the data of a group of patients having CKD with eGFR less than 60 ml/min with multivessel CAD who underwent revascularization by PCI or revascularization by CABG and were compared as regards in-hospital and one-year MAACE. Results: A total of 565 patients were reviewed in this study, 230 patients had multivessel PCI using DES while 335 patients had CABG. Comparing both revascularization groups regarding in-hospital MACCE, patients who had mutli-vessel PCI had significantly lower in-hospital mortality, cerebrovascular events (stroke/TIA) and lower total MACCE than patients who had CABG (P-value = 0.03 & 0.01 & 0.04 respectively). When comparing both revascularization groups regarding one-year MACCE, patients who had mutli-vessel PCI had significantly lower cerebrovascular events and total MACCE than those patients who had CABG (P-value = 0.02 & 0.03 respectively). Conclusion: This is a retrospective study to determine which strategy is better for revascularization of CKD patients having multivessel CAD; we can conclude that multi-vessel PCI using DES for CKD patients and multivessel CAD had advantages over CABG regarding in-hospital and one-year cerebrovascular accidents (TIA/stroke) and regarding total MACCE. Larger randomized controlled trials are required to confirm our findings.
