  • Time to re-hospitalization with nonfatal reinfarction, heart failure and target vessel revascularization [ Time Frame: 30 days to 10 years ] [ Designated as safety issue: No ]
  • Time to all-cause death or new myocardial infarction (first occurring) or in hospital treatment for heart failure [ Time Frame: 30 days to 10 years ] [ Designated as safety issue: No ]
  • Time to acute coronary occlusion, stent thrombosis and restenosis in treated lesions [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Length of hospital stay [ Time Frame: 1 month ] [ Designated as safety issue: No ]
  • TIMI-flow grade [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
    TIMI-flow, or Thrombolysis in Myocardial Infarction grading of flow is a semiquantitative method to assess coronary artery flow following balloon angioplasty.

Thrombus Aspiration in Myocardial Infarction
Thrombus Aspiration in ST- Elevation Myocardial Infarction in Scandinavia
Treatment of myocardial infarction (blood clot in the arteries of the heart) has improved after introduction of 24/7 balloon angioplasty to open the blocked artery. However, the clot itself is not routinely removed but recent data in smaller trials indicate that this might improve recovery and prognosis. In this multicenter study of 5000 patients referred to Scandinavian hospitals for myocardial infarction the investigators test the hypothesis that patients randomized to treatment with thrombus aspiration (removing the blood clot by manual suction) before conventional angioplasty will have a reduced risk of death, fewer rehospitalisations, fewer new myocardial infarctions, reduced risk of heart failure, better coronary artery flow after angioplasty and greater reduction of infarct size compared to patients randomized to conventional angioplasty alone.

Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Acute Myocardial Infarction
Procedure: Thrombus aspiration
Aspiration of thrombus material before angioplasty
  • Experimental: Thrombus aspiration
    Thrombus aspiration is then followed by standard balloon angioplasty (PCI).
    Intervention: Procedure: Thrombus aspiration
  • Active Comparator: Standard balloon angioplasty (PCI)
    Intervention: Procedure: Thrombus aspiration
