Determinants of bare-metal stent use in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention.

摘要: Bare-metal stent (BMS) use in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) has been associated higher rates of adverse cardiac events, including target lesion and vessel revascularization. The purpose the present study was to determine which clinical characteristics predict BMS STEMI PCI. Data were prospectively collected from all who underwent PCI for between January 1, 2004 December 31, 2007 at four New York State academic medical centers. Demographics, baseline history, procedural characteristics, in-hospital outcomes compared receiving DESs versus BMSs. Of 1394 studied, a total 290 (20.8%) received while 1104 (79.2%) DES. Patients more likely have prior artery bypass graft surgery, PCI, peripheral vascular disease, diabetes mellitus, be Hispanic uninsured. They also thrombosis worse left ventricular ejection fraction (LVEF). had significantly longer hospital length stay trend toward all-cause mortality. In multivariate analysis, independent predictors included uninsured status (versus private insurance) (odds ratio [OR], 2.81; 95% confidence interval [CI], 1.70-4.67), disease (OR, 1.96; CI, 1.08- 3.56), LVEF 0.98; 0.97-0.99). conclusion, this analysis contemporary cohort lack health insurance, independently implantation
