Abstract
Objective:To evaluate the diagnostic value of coronary arrery computed tomographic angiography(CTA)in acute coronary syndrome(ACS).Method:A total of 450 patients with clinical diagnosis of ACS admitted to the First Affiliated Hospital of Xiamen University from March 2023 to February 2024 were selected as the study objects.Coronary CTA and coronary angiography(CAG)were performed in all patients.Taking CAG results as the"gold standard",and the diagnostic value of coronary CTA was compared and analyzed.Result:450 vessels of coronary artery CTA and CAG both examined.Among them,336 stenosis vessels were detected in CTA,and the numbers of left main,left circumflex,left anterior descending and right coronary arteries were 75,80,97 and 84,respectively.CAG detected 342 stenosis vessels,and the number of left main,left circumflex,left anterior descending and right coronary arteries were 78,83,93 and 88,respectively.There was no significant difference in the detection results of left main artery,left circumflex branch,left anterior descending branch and right coronary artery between the two methods(P>0.05).There were 114,190,76 and 70 CTAs with no stenosis,mild stenosis,moderate stenosis and severe stenosis,respectively.108,193,79 and 70 branches of CAG were detected without stenosis,mild stenosis,moderate stenosis and severe stenosis,respectively.There was no significant difference in the degree of coronary artery stenosis between the two methods(P>0.05).There were 287 soft plaques and 49 hard plaques detected by CTA,and the differences were not statistically significant compared with 280 and 62 detected by CAG(P>0.05).Conclusion:Coronary CTA is an effective diagnostic method for ACS patients,and its value in diagnosing the degree of coronary artery stenosis and the nature of plaque is consistent with CAG.关键词
