A Trial Evaluating the Efficacy and Safety of Tenecteplase Together With Unfractionated Heparin Prior to Early Percutaneous Coronary Intervention (PCI) as Compared to Standard Primary PCI in Patients With Acute Myocardial Infarction (ASSENT 4 PCI) - Full Text View

Purpose

To show whether addition of thrombolytic treatment by a single bolus injection of tenecteplase prior to early standard PCI (percutaneous coronary intervention) will improve the clinical outcome in patients with large acute myocardial infarcts as compared to primary PCI alone.

Primary Outcome Measures:

As the main criteria for measuring clinical outcome, the frequency of death, heart failure or cardiogenic shock is compared in the two treatment groups during 90 days after the acute heart attack.

Secondary Outcome Measures:

As a secondary outcome any other in-hospital complication and bleeds (including intracranial bleeds) are recorded and the frequency compared in the two treatment groups.
Furthermore, intracoronary blood flow measured during catheterisation before and after the PCI and a laboratory blood test (BNP) predicting developing heart failure are compared between the groups.
