Effects and safety of PercuSurge distal protection device in coronary intervention in acute myocardial infarction / 中国介入心脏病学杂志

ABSTRACT

Objective To evaluate the effects and safety of PercuSurge distal protection device(DPD) in coronary intervention in patients with acute myocardial infarction. Methods From December 2003 to December 2005, 174 acute myocardial infarction patients who received primary coronary intervention were included into this study. Patients were divided into the DPD group (n=78) and the control group (n=96) according to whether Percusurge DPD was attempted during emergency PCI. The basic clinical characteristics, angiographic results, and follow up data before discharge were compared. TIMI flow grades and myocardial blush grades were performed in all cases after emergency PCI. Results Success application was achieved in 72 out of 78 patients with PercuSurge DPD with varies extent of material collected from the basket. There was no significant difference between the two groups in basic clinical characteristics and angiogram before PCI. Post-PCI TIMI flow grades (94.9% vs 79.2%) and myocardial blush grades (2.65?0.68 vs 2.22?0.94) were significantly higher in the DPD guoup than in the control group(P
