Brief Summary:
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.

Arm Intervention/treatment
Experimental: Thrombus aspiration
Thrombus aspiration is then followed by standard balloon angioplasty (PCI).
 Procedure: Thrombus aspiration
Aspiration of thrombus material before angioplasty
Active Comparator: Standard balloon angioplasty (PCI) Procedure: Thrombus aspiration
Aspiration of thrombus material before angioplasty


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. All-cause death [ Time Frame: 30 days ]
    Death from any cause will be registered via national registries during the first 30 days after study inclusion.


Secondary Outcome Measures :
  1. Time to re-hospitalization with nonfatal reinfarction, heart failure and target vessel revascularization [ Time Frame: 30 days to 10 years ]
  2. 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 ]
  3. Time to acute coronary occlusion, stent thrombosis and restenosis in treated lesions [ Time Frame: 1 year ]
  4. Length of hospital stay [ Time Frame: 1 month ]
  5. TIMI-flow grade [ Time Frame: 3 hours ]
    TIMI-flow, or Thrombolysis in Myocardial Infarction grading of flow is a semiquantitative method to assess coronary artery flow following balloon angioplasty.

  6. All-cause death [ Time Frame: 1 year to 10 years ]
