Abstract

Abstract: Abject To study the effects of multi-slice CT and DSA on patency and stenosis degree of patients with acute coronary syndrome after coronary artery stent implantation. Eighty patients with acute coronary syndrome diagnosed and treated in our hospital from August 2017 to November 2018 were selected as the study subjects. After percutaneous coronary intervention (PCI) operation, DSA and 64-slice spiral CT were performed in all patients. The differences of coronary stenosis and patency between different examinations and the consistency of different examinations were analyzed. Through paired chi-square test of CT results and DSA results, there was no significant difference between the two groups. The two methods had good consistency in diagnosis of coronary artery stenosis. There was no difference in diagnosis of wall thickness and diameter between the two methods. In statistical significance, the two methods have good consistency in the diagnosis of wall thickness and diameter of patients. In conclusion, multi-slice CT and DSA have a high consistency in the diagnosis of patency and stenosis degree after coronary artery stent implantation in patients with acute coronary syndrome. It is suggested that they be popularized in clinic.

Key words: CT, percutaneous coronary intervention, interventional X-ray angiography system, consistency, stenosis
