Abstract Objective: To compare the effects of 256-slice spiral CT angiography (CTA) and digital subtraction angiography (DSA) in the diagnosis of coronary myocardial bridge. Methods: A total of 120 patients diagnosed with coronary heart disease in the hospital from June 2017 to June 2020 were selected as the study objects. All patients were diagnosed by 256-slice CTA and DSA. The situation of coronary artery stenosis and detection rate of myocardial bridge were compared between the two groups. Results: Through 256-slice CTA, a total of 93 cases with coronary artery stenosis were verified, including 56 cases with mild stenosis, 28 cases with moderate stenosis, and 9 cases with severe stenosis. Through DSA 85 cases of coronary artery stenosis were verified, and the mild, moderate and severe stenosis were 55 cases, 21 cases and 9 cases respectively. The two methods had good consistency in the diagnosis of coronary artery disease (kappa = 0.741, P<0.001). The detection rate of coronary myocardial bridge by 256-slice CTA was 80.00%, significantly higher than 68.33% by DSA (P<0.05). Conclusion: 256-slice CTA can directly display the morphological characteristics of myocardial bridge and blood vessels. Compared with DSA, it has more advantages in the diagnosis of abnormal anatomical structure and myocardial bridge. However, this method requires high for patients’ heart rate, and CTA and DSA have high consistency in the detection of coronary artery lesions. Therefore, clinicians can flexibly apply it according to the actual situation in the actual detection process, so as to play their respective advantages and improve the detection rate of myocardial bridge in patients
