Review Articles

There are no dedicated data to guide drug-eluting stent (DES) versus bare-metal stent (BMS) selection in patients with end-stage renal disease undergoing dialysis (ESRD-D). It is unclear whether long-term benefits of a specific stent type outweigh risks in this population at high risk for both bleeding and ischemic events. We performed a meta-analysis of nonrandomized studies extracted from PubMed, Scopus, and EMBASE, assessing the safety and effectiveness of DES versus BMS in ESRD-D patients. Odds ratios (OR) and 95% confidence intervals (CI) were computed with the Mantel–Haenszel method. Random-effects model was used for all analyses. A total of 17 nonrandomized studies (N = 63,157; 41,621 DES and 21,536 BMS) met the inclusion criteria and were included for the final quantitative analysis: median follow-up of 1 year (range: 9 months to 6 years). The use of DES in ESRD-D patients was associated with lower all-cause mortality (OR 0.75, 95% CI 0.64–0.89, P < 0.001) compared with BMS. The use of DES was also associated with lower rates of cardiovascular mortality (OR 0.75, 95% CI 0.60–0.99, P = 0.047) and target lesion/vessel revascularization (OR 0.78, 95% CI 0.64–0.94, P = 0.01). However, there were no differences in noncardiovascular mortality, myocardial infarction, stent thrombosis, stroke, or major bleeding in DES versus BMS. In this largest meta-analysis of long-term outcomes after percutaneous coronary intervention in ESRD-D patients, DES was associated with lower rates of all-cause mortality, target lesion/vessel revascularization, and cardiovascular death.
