Drug-eluting Stents And Bare Metal Stents In Acute ST Segment Elevation Myocardial Infarction, The Application Of Comparative Study

Objective:Evaluation of drug-eluting stents (DES) and bare-metal stents (BMS) in acute ST segment elevation myocardial infarction (STEMI) the application of the safety and efficacy.Methods:Collected from May2011to January2013, underwent emergency percutaneous coronary intervention (PCI) for the treatment of a total of153patients with STEMI, all in come on12h adept emergency PCI, according to the patients with the infarction related blood vessels, target lesion in DES and BMS, divided into DES and BMS group. Including DES group95cases,58cases of BMS group. At least1year of follow-up, line telephone follow-up, outpatient follow-up review, the length of coronary angiography. Analysis after stent implantation during hospitalization and after discharge major adverse cardiovascular events (MACE, including psychogenic death, again hair, myocardial infarction, ischemic vascular remodeling and angina, etc.), stent thrombosis, stent restenosis occurs.Results:DES placing stents length is greater than the BMS group (27.72±6.54mm,24.6±5.67mm, P<0.000). Differences of two groups of patients during hospitalization and follow-up MACE had no statistical significance (P>0.05). Two groups of patients with stent thrombosis rate, rate of target lesion revascularization, there was no statistically significant difference (P>0.05). DES compared with BMS, stent restenosis rate decreases, the difference was statistically significant (P<0.05).Conclusion:In patients with acute STEMI, using DES compared with BMS, within a year in MACE, stent thrombosis, and target lesion revascularization rate has no obvious differences. Using DES stent restenosis rate to decrease. But BMS in STEMI application has certain status.
