Thrombus Aspiration in Myocardial Infarction

Not Applicable
Completed
Conditions
Acute Myocardial Infarction
Interventions
Procedure: Thrombus aspiration
Registration Number
NCT01093404
Lead Sponsor
Region Örebro County
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.

Primary Outcome Measures
NameTimeMethod
All-cause death30 days

Death from any cause will be registered via national registries during the first 30 days after study inclusion.

Secondary Outcome Measures
NameTimeMethod
Time to re-hospitalization with nonfatal reinfarction, heart failure and target vessel revascularization30 days to 10 years
Time to all-cause death or new myocardial infarction (first occurring) or in hospital treatment for heart failure30 days to 10 years
Time to acute coronary occlusion, stent thrombosis and restenosis in treated lesions1 year
Length of hospital stay1 month
TIMI-flow grade3 hours

TIMI-flow, or Thrombolysis in Myocardial Infarction grading of flow is a semiquantitative method to assess coronary artery flow following balloon angioplasty.

All-cause death1 year to 10 years
