Abstract：Objective To explore the value of multi-slice spiral CT one-stop combined examination in screening acute chest pain triad lesions.Methods 96 patients with suspected acute chest pain triad lesions admitted to the emergency department from November 2021 to October 2023 were selected.All patients underwent a one-stop combination screening with multi-slice spi-ral CT(pulmonary artery CTA,aortic CTA,coronary CT scan integration),with coronary angiography as the gold standard.At the same time,the reconstruction of the tissue structure of the patient's aorta,pulmonaryartery,and coronary artery after spiral CT ex-amination was analyzed,and the image quality and diagnostic efficacy were analyzed.Results Among 96 suspected patients with acute chest pain triad lesions,a total of 49 cases of coronary artery stenosis lesions were detected(23 cases of single vessel lesions,14 cases of double vessel lesions,and 12 cases of triple vessel lesions);There were 10 cases of aortic dissection aneurysm,10 cases of pulmonary embolism,8 cases of pericarditis,7 cases of pneumothorax,6 cases of pulmonary infection,and 6 cases of pleural effusion.Under multi-slice spiral CT examination,the diagnostic rate was 92.71%,sensitivity was 93.18%,specificity was 87.50%,and there was no difference compared with coronary angiography examination,P<0.05;Out of 96 patients,a total of 1245 coronary artery images were obtained,with excellent,good,and poor proportions of 82.01%,12.93%,and 5.06%respectively.Conclusion Multi slice spiral CT one-stop combined examination screening can provide clear diagnostic efficacy in the diagno-sis of acute chest pain triad lesions,timely and accurately indicate the etiology of acute chest pain patients,and has important clini-cal significance for the diagnosis and differentiation of clinical chest pain triad lesions.
