| Popis: | Objectives The aim of this study was to compare long-term clinical outcomes in patients treated with new-generation drug-eluting stent (DES) or early-generation DES in a real-world registry. Background New-generation DESs have proved to be more effective and safer than early-generation DES in randomized trials. However, the effects of new-generation DES versus early-generation DES in everyday clinical practice deserve further verification. Methods A propensity-score and inverse-probability weighted analysis of 5,332 patients undergoing DES implantation (2,557 new-generation and 2,775 early-generation) between January 1, 2007 and June 30, 2011 was performed, with a median follow-up of 3 years. We assessed the incidence of major adverse cardiovascular events (MACE: all-cause death, nonfatal myocardial infarction [MI], and target vessel revascularization [TVR]), and angiographic stent thrombosis (ST) during follow-up. Results At 3-years, new-generation DES in comparison with early-generation DES were associated with a reduced risk of MI (5% versus 7.4%, hazard ratio [HR] = 0.65, 95% confidence interval [CI] = 0.51–0.82, P = 0.0004) and angiographic ST (0.5% vs. 1.1%, HR = 0.35, 95% CI 0.17–0.72, P = 0.004), whereas, the risk of TVR (10.9% vs. 13.5%; HR 0.99, 95% CI 0.84–1.16, P = 0.99) and overall MACE was not significantly different (19.2% vs. 22.4%, HR = 0.94, 95% CI = 0.83–1.07, P = 0.35). Conclusions Our data from a large all-comers multicenter registry confirm that, in comparison with early-generation DES, the use of new-generation DES is associated with similar efficacy and increased long-term safety, because of a reduced risk of ST and MI. © 2014 Wiley Periodicals, Inc. |
