Abstract

To evaluate the influences of different aspiration results by Diver C.E. aspiration thrombectomy catheter on myocardium perfusion and clinical outcomes during emergency PCI (percutaneous coronary intervention) for the patients with acute ST segment elevation myocardial infarction (STEMI). The patients undergoing emergent PCI and using Diver C.E. aspiration thrombectomy catheter with STEMI from July 2008 to February 2011 were enrolled into the study group. According to the aspiration results, they were divided into 2 groups: aspiration-positive group (n = 38) and aspiration-negative group (n = 28). And those undergoing routine PCI alone during the same period were enrolled into the control group (n = 66). The baseline profiles, immediate post-operative CAG (coronary angiography) and follow-up data were compared. No significant baseline differences existed among 3 groups. Compared with the control group, all parameters significantly improved in the aspiration-positive group. But in the aspiration-negative group, the differences of slow flow/no-reflow and major adverse cardiovascular events (MACE) were insignificant (P > 0.05). Compared with the aspiration-negative group, cTFC (29 ± 9 vs 35 ± 11 frames, P < 0.05), ST segment (90% ...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
