Information provided by:

  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.

Condition Intervention Phase
Myocardial Infarction Drug: Tenecteplase Procedure: PCI Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase IIIb - IV, Randomised, Open Label Trial Evaluating the Efficacy and Safety of Tenecteplase Together With Unfractionated Heparin Prior to Early PCI as Compared to Standard Primary PCI in Patients With Acute Myocardial Infarction. ASSENT 4 PCI (Assessment of the Safety and Efficacy of a New Treatment Strategy for Acute Myocardial Infarction.)
