A Dutch trial enrolled more than 1000 patients with major heart attack and needed emergency angioplasty and assigned them to either conventional PCI ( percutaneous coronary intervention) or thrombus aspiration ( suctioning out the clot ). They found that suctioning out blood clots in blocked arteries could improve blood flow and clinical outcomes in heart attack patients.
An expert said the findings showed what other trials have shown and there were weaknesses in the study. The trial was published in the New England J of Medicine(NEJM).
