[Comparison of Direct Stenting Versus Stending After Pre-Dilation in ST-Elevation Myocardial Infarction]

Abstract

Aim: To study was to assess in-hospital outcomes of direct coronary stenting (DS) compared with stenting after predilation (PD) in patients with ST-elevation myocardial infarction (STEMI).

Material and methods: Data were collected from all patients (n=1103) with STEMI subjected to primary PCI in Tyumen cardiology center from 2006 to 2014. The clinical and angiographic characteristics, in-hospital outcomes, as well as predictors of no-reflow phenomenon were analyzed. The composite of in-hospital death, myocardial infarction (MI) and stent thrombosis were defined as major adverse cardiac events (MACE).

Results: Altogether 563 patients (51 %) underwent DS, and in 540 (49 %) stents were implanted after PD. Patients in DS group compared with those in PD group were younger (57.9±10.9 vs 60±11.5 years; p=0.001), less often had chronic kidney disease (5.2 vs 8.4 %; р=0.034), more often recieved prehospital thrombolysis (25 vs 11.9 %; p.
