Background: Chronic kidney disease (CKD) is highly prevalent in patients with coronary artery disease (CAD).
Objective: The outcome following revascularization using contemporary technologies (new-generation abluminal sirolimus-eluting stents with thin struts) in patients with CKD (i.e., glomerular filtration rate of < 60 mL/min/1.73m2) and in patients with hemodialysis (HD) is unknown.
Methods: e-Ultimaster is a prospective, single-arm, multi-center registry with clinical follow-up at 3 months and 1 year.
Results: A total of 19,475 patients were enrolled, including 1466 patients with CKD, with 167 undergoing HD. Patients with CKD had a higher prevalence of overall comorbidities, multiple/small vessel disease (≤ 2.75 mm), bifurcation lesions, and more often left main artery treatments (all p < 0.0001) when compared with patients with normal renal function (reference). CKD patients had a higher risk of target lesion failure (unadjusted OR, 2.51 [95% CI 2.04-3.08]), target vessel failure (OR, 2.44 [95% CI 2.01-2.96]), patient-oriented composite end point (OR, 2.19 [95% CI 1.87-2.56]), and major adverse cardiovascular events (OR, 2.34 [95% CI 1.93-2.83, p for all < 0.0001]) as reference. The rates of target lesion revascularization (OR, 1.17 [95% CI 0.79-1.73], p = 0.44) were not different. Bleeding complications were more frequently observed in CKD than in the reference (all p < 0.0001).
Conclusion: In this worldwide registry, CKD patients presented with more comorbidities and more complex lesions when compared with the reference population. They experienced higher rate of adverse events at 1-year follow-up. One-year summary outcomes of contemporary PCI in renal insufficiency.
