Reanalysis of criminals vascular with fixed stenosis of acute ST segment elevation myocardial infarction / 中国综合临床

ABSTRACT

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 Medical University.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 majority of serious vascular stenosis patients have acute STEMI.
