Abstract Objective To explore the value of coronary CT angiography(CTA)in evaluating acute coronary syndrome(ACS)and the degree of coronary stenosis. Methods A total of 87 suspected ACS patients were selected.All patients underwent coronary CTA and coronary angiography(CAG)to assess the degree of coronary stenosis.The results of CAG were used as the gold standard to analyze the diagnostic value of coronary CTA for ACS and the degree of coronary stenosis. Results Among the 87 suspected ACS patients,71 cases were detected by CAG,accounting for 81.61%;among them,14 had mild stenosis,32 had moderate stenosis,19 had severe stenosis,and 6 had complete occlusion.Based on the "gold standard"of CAG,the sensitivity,specificity,and accuracy of coronary CTA for diagnosing ACS were 98.59%,87.50%,and 96.55%,respectively,with good consistency compared to CAG results(Kappa=0.882).The diagnostic agreement rates for mild,moderate,severe,and complete occlusion in coronary CTA were and,respectively,with a total accuracy of 95.78%.Additionally,the consistency between coronary CTA and CAG results regarding the degree of coronary stenosis was good(Kappa=0.938). Conclusion Coronary CTA has high diagnostic value for ACS and can effectively assess the degree of coronary stenosis,providing Objective evidence for clinical diagnosis and treatment.
