Death or cardiogenic shock or congestive heart failure within 90 days [ Time Frame: 90 days ]
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.

  • Death or cardiogenic shock or congestive heart failure within 30 days [ Time Frame: 30 days ]
  • Cardiogenic shock or congestive heart failure within 90 days [ Time Frame: 90 days ]
  • Death [ Time Frame: 90 days ]
  • Cardiogenic shock [ Time Frame: 90 days ]
  • Reinfarction [ Time Frame: 90 days ]
  • Repeat target vessel revascularisation (TVR) [ Time Frame: 90 days ]
  • Rehospitalisation for congestive heart failure [ Time Frame: 90 days ]
  • Rehospitalisation for cardiogenic shock [ Time Frame: 90 days ]
  • Rehospitalisation for other cardiac reasons [ Time Frame: 90 days ]
  • Congestive heart failure [ Time Frame: 90 days ]
  • N-terminal pro-brain natriuretic peptide (NT pro-BNP) [ Time Frame: 90 days ]
  • Disabling stroke [ Time Frame: 90 days ]
  • Total stroke [ Time Frame: 90 days ]
  • Rehospitalisation for stroke or ICH (intrancranial haemorrhage) [ Time Frame: 90 days ]
  • 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.

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)
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.)
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.
