Abstract：Objective To study the application of CT coronary angiography and digital subtraction angiography （DSA） in the clinical diagnosis of acute coronary syndrome. Methods Twenty-eight patients with acute coronary syndrome admitted in Veterans Hospital of Liaocheng City from January 2016 to October 2017 were selected as subjects. All the patients were given CT coronary angiography and DSA examination, and the diagnostic precision of two methods were compared. Results CT coronary angiography results showed that there were 26 cases of acute coronary syndrome, the true positive rate was 92.86%, the true negative rate was 100%, the diagnostic sensitivity was 100%, and the specificity was 89.29%. DSA results showed that there were 24 cases with acute coronary syndrome, true positive rate was 78.57%, the true negative rate was 100%, the diagnostic sensitivity was 100%, and the specificity was 82.14%. The sensitivity and true negative rate of the two detection methods had no statistically significant difference (P ＞ 0.05). The positive rate and specificity of CT coronary angiography were higher than those of DSA, and the difference was statistically significant (P ＜ 0.05). In addition, the number of plaques examined by CT coronary angiography was less than DSA. There was no significant deifference of calcified plaque and non calcified plaque detection rate by CT coronary angiography or DSA (P ＞ 0.05). Conclusion In the diagnosis process acute coronary syndrome, CT coronary angiography method is easy to handle and and it has high accuracy, that can be used widely in clinic, so as to provide more effective protection for patients.
