NCT01013038

Brief Summary

In this trial, the investigators will evaluate the effect of thrombus aspiration followed by stent implantation in improving myocardial blush grade in patients with acute non-ST-elevation myocardial infarction compared to conventional percutaneous coronary intervention (PCI).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of acute NSTEMI defined by
  • Chest pain suggestive for myocardial ischemia for at least 30 minutes,
  • Time from onset of symptoms of less than 72 hours
  • ECG with ST-segment shifts (depression of \>0.1 mV in at least two contiguous leads or transient ST-segment elevation \>0.1 mV in at least two contiguous leads for less than 30 minutes) and/or T-wave changes (inversion of \>0.15 mV in at least two contiguous leads)
  • Positive cardiac troponin T \>0,01 μg/L.
  • Clinical indication for urgent PCI of the ischemia-related target lesion as identified at coronary angiography

You may not qualify if:

  • Persistent ST-elevation of more than 0.1 mV in 2 or more leads
  • Presence of cardiogenic shock
  • Inability to obtain informed consent
  • Known existence of a life-threatening disease with a life expectancy of less than 6 months
