Propensity-Score Matched Comparison of Midterm Angiographic Outcomes of Sirolimus- Versus Everolimus- and Biolimus-Eluting Stents for De Novo Coronary Stenosis

Comparison of Limus-Eluting and Paclitaxel-Eluting Stents for Coronary Intervention in Patients with Chronic Kidney Disease

Chronic kidney disease (CKD) patients have worse adverse cardiovascular outcomes after percutaneous coronary intervention (PCI). Clinical outcomes comparing a limus-eluting stent (LES) to a paclitaxel-eluting stent (PES) in patients with CKD remain controversial.A systematic search was conducted using PubMed, EMBASE, and Cochrane Library. A pooled odds ratio (OR) and 95% confidence interval (CI) were used to calculate original data. We conducted heterogeneity, quality assessment, and publication bias analyses.A total of 17 trials involving 10,724 patients were included. No significant differences were found regarding target vessel revascularization, target lesion revascularization (TLR), stent thrombosis (ST), myocardial infarction (MI), all-cause mortality, and major adverse cardiac events (MACE) between first-generation LES implantation and PES implantation. Second-generation LES implantation was associated with lower rates of all-cause mortality (OR, 0.56; 95% CI, 0.39-0.82; P = 0.003), MACE (OR, 0.61; 95% CI, 0.38-0.97; P = 0.04), and ST (OR, 0.45; 95% CI, 0.26-0.77; P = 0.004) compared with PES implantation. In all, the long-term all-cause mortality rate was significantly lower after LES implantation than after PES implantation in patients with CKD (OR, 0.78; 95% CI, 0.66-0.93; P = 0.004). However, second-generation LES implantation resulted in a higher rate of TLR (OR, 2.23; 95% CI, 1.53-3.25; P < 0.001) than PES implantation in dialysis patients.In patients with CKD, first-generation LES and PES implantation had comparable mortality and morbidity. Second-generation LES implantation was superior to PES in reducing long-term mortality, MACE, and ST. However, PES may be more effective than LES in dialysis patients.
