Upstream High‐Dose Tirofiban Does Not Reduce Myocardial Infarct Size in Patients Undergoing Primary Percutaneous Coronary Intervention: A Magnetic Resonance Imaging Pilot Study

摘要

BackgroundPrimary percutaneous coronary intervention (PCI) is more effective than fibrinolytic therapy for ST‐segment elevation myocardial infarction (STEMI), but initial treatment delay to intervention is the main limitation of this strategy. Hypothesis: Upstream use of high‐dose tirofiban could reduce myocardial infarct size, using analysis of contrast‐enhanced magnetic resonance imaging (CE‐MRI).
