First received: November 7, 2008
Last updated: December 2, 2008
Last verified: November 2008
The main objective is to compare a fibrinolytic strategy with an interventional strategy initiated as early as possible, preferably in the pre-hospital phase, with respect to resolution of ST-segment elevation at 120 minutes after inclusion and Thrombolysis In Myocardial Infarction (TIMI) flow grade evaluated at a mandated coronary angiography 5 to 7 days after inclusion.

Condition Intervention Phase
Acute Myocardial Infarction Drug: reteplase 10+10 U Procedure: primary PCI Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Very Early Initiation of Treatment With Thrombolysis and Low Molecular Weight Heparin, Versus Abciximab and Low Molecular Weight Heparin Followed by Percutaneous Coronary Intervention, for Acute ST-Elevation Myocardial Infarction

Further study details as provided by Sahlgrenska University Hospital, Sweden:

Primary Outcome Measures:
  • Number of Patients With Thrombolysis In Myocardial Infarction (TIMI) Flow Grade 3 [ Time Frame: 5-7 days after inclusion ]
  • Number of Patients With ST-Segment Elevation Resolution Equal or More Than 50% [ Time Frame: 120 minutes after inclusion ]

Secondary Outcome Measures:
  • Reinfarction [ Time Frame: 30 days ]
  • Death [ Time Frame: 30 days ]
  • Stroke [ Time Frame: 30 days ]

Enrollment: 205
Study Start Date: November 2001
Study Completion Date: June 2004
Primary Completion Date: June 2003 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: thrombolysis Drug: reteplase 10+10 U
comparison to primary PCI
Other Name: Rapilysin
Active Comparator: invasive Procedure: primary PCI
comparison to thrombolysis
Other Name: primary percutaneous coronary intervention

Detailed Description:

Patients in the fibrinolytic group received an intravenous injection of 30 mg enoxaparin followed by subcutaneous injections of 1 mg/kg body weight every 12 hours during hospital stay.

Patients in the invasive group were given an intravenous injection of enoxaparin of (0.75 mg/kg body weight) and abciximab as a intravenous bolus (0.25 mg/kg body weight) followed by a 12 hour infusion (10 microg/minute).

Secondary outcome measures were death, myocardial infarction and stroke alone or as a composite at 30 days.

Data on use of health care resources, loss of production and health-related quality of life were collected during one year. Cost-effectiveness was determined by comparing costs and quality-adjusted survival.
