Safety and efficacy of drug-eluting stents compared with bare metal stents in ST-elevation myocardial infarction.
Drug-eluting stents (DES) reduce restenosis and the need for repeat revascularization, but patients with ST-segment elevation myocardial infarction (STEMI) were excluded from many of the trials that established the safety and efficacy of DES. Because of the unstable nature of lesions associated with STEMI, these patients are considered high risk, and often experience higher rates of adverse events. There is concern that DES may increase the risk of stent thrombosis, particularly late and very late stent thrombosis, in STEMI patients. Evidence also suggests that although DES reduce target vessel revascularization, this benefit may be lost after extended follow-up due to procedures necessitated by increased stent thrombosis. Several randomized trials, meta-analyses, and registry studies have been conducted to compare DES with bare metal stents in patients with STEMI, but many of the studies are not large scale and the length of follow-up has been limited in duration. This review summarizes the data comparing DES with bare metal stents in patients with STEMI.
