Nobori And Uncoated Stent In Coronary Attack

This study is currently recruiting participants. (see Contacts and Locations)
Verified November 2014 by NAUSICA Investigators
NPO International TRI Network

Drug-eluting stents reduce rates of restenosis and reintervention, as compared with uncoated stents. Data are limited regarding the safety and efficacy of Nobori (Biolimus A9 Eluting Stent) in primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). Accordingly, the investigators will compare the outcomes of primary PCI for AMI between patients receiving Nobori versus uncoated stents.

Condition Intervention
Acute Myocardial Infarction
Device: Biolimus A9 eluting stents
Procedure: uncoated stent

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Clinical Trial of Nobori Versus Uncoated Stents In Acute Myocardial Infarction
