BACKGROUND: Decreased estimated glomerular filtration rate (eGFR) is a strong predictor of both mortality and subsequent cardiac events after percutaneous coronary intervention. The safety and efficacy of drug-eluting (DESs) versus bare-metal stents (BMSs) in this population have not been evaluated adequately.
STUDY DESIGN: A systematic review and meta-analysis.
SETTING & POPULATION: Studies involving the comparison of clinical outcomes between DESs and BMSs in patients with eGFR <60 mL/min/1.73 m(2). Studies exclusively involving patients with ST-segment elevation myocardial infarction were excluded.
SELECTION CRITERIA FOR STUDIES: MEDLINE (on Ovid), EMBASE, and the Cochrane Library databases from 2002-2013 were searched for studies comparing DESs with BMSs in patients with eGFR <60 mL/min/1.73 m(2).
INTERVENTION: DES versus BMS implantation.
OUTCOMES: Mortality, repeat revascularization, myocardial infarction, and stent thrombosis.
RESULTS: Data from 26 comparative studies with 66,840 patients were included. Compared with BMSs, DESs were associated with significant reductions in repeat revascularization (OR, 0.61; 95% CI, 0.50-0.74; P < 0.001) and myocardial infarction (OR, 0.85; 95% CI, 0.79-0.92; P < 0.001), with no detectable difference in stent thrombosis (OR, 0.72; 95% CI, 0.46-1.12; P = 0.1). The superiority of DESs over BMSs in decreasing mortality also was documented (OR, 0.77; 95% CI, 0.65-0.90; P = 0.01). This survival benefit of DESs over BMSs was attenuated in randomized controlled trials or adjusted observational studies versus unadjusted observational studies.
LIMITATIONS: Most studies were observational studies. Meta-analysis was not performed on individual patient data.
CONCLUSIONS: DES use in patients with eGFR <60 mL/min/1.73 m(2) is associated with a reduced rate of repeat revascularization and myocardial infarction without increased risk of stent thrombosis. The true effect of DESs versus BMSs on mortality needs to be confirmed by randomized controlled trials.
