Nobori And Uncoated Stent In Coronary Attack

August 23, 2018 updated by: Shigeru Saito

Clinical Trial of Nobori Versus Uncoated Stents In Acute Myocardial Infarction

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.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
