急性ST段抬高型心肌梗死罪犯血管固定狭窄评估分析

Reanalysis of criminals vascular with fixed stenosis of acute ST segment elevation myocardial infarction

目的急性ST段抬高型心肌梗死（STEMI）急诊经皮冠状动脉介入（PCI）术中行血栓抽吸术，评价冠状动脉造影定量分析（QCA）方法测量罪犯血管固定狭窄的价值。方法选择2012年9月1日至2013年10月31日在温州医科大学附属第一医院接受急诊PCI术加血栓抽吸治疗的STEMI患者164例，使用QCA法测量血栓抽吸术后的罪犯血管固定狭窄率。结果血管狭窄率〉50％男性占69．5％，血管狭窄率〉70％女性占40．2％；前降支固定狭窄率为（54．75±29．72）％，回旋支为（55．25±32．23）％，右冠状动脉为（56．40±29．76）％，3支血管固定狭窄率比较差异无统计学意义（F值分别为6．036、0．955、0．055，P均〉0．05）。结论绝大多数的急性STEMI患者存在严重的血管狭窄。

Objective To evaluate quantitative coronary angiography （QCA） measurement of culprit vessel fixed stenosis in acute ST segment elevation myocardial infarction （STEMI） emergency interventional thrombus aspiration. Methods One hundred and sixty-fore cases of STEMI patients accepting emergency interventional operation and thrombus aspiration treatment were choosed from September 2012 to October 2013 in the First Affiliated Hospital of Wenzhou MedicalUniversity. Thrombus Aspiration measuring vessel was carried after criminals using fixed stenosis rate QCA methods. Results The vascular stenosis rate was more than 50% in 69. 5% of the male patients,vascular stenosis rate was more than 70% in 40. 2% of the female patients,the anterior descending branch of the rami anterior descendens （LAD） （ 54. 75% ± 29.72%, n = 76）, Left circumflex artery （LCX） （ 55.25 % ± 32. 23 %, n = 20）, arteriae coronaria dextra （ RCA ） （ 56. 40% ± 29. 76%, n = 68 ）. There was no difference between LAD,LCX and RCA （F= 6. 036,0. 955,0. 055;P〉0. 05）. Conclusion The most maiority of serious vascular stenosis patients have acute STEMI.
