Objective To analyze the incidence of coronary myocardial bridge (MB) of the Uyghur and Han peoples with 64-slice CT. Methods A total of 1350 patients with suspected of coronary disease or other diseases underwent coronary angiography with 64-slice CT, among them 341 patients were diagnosed as MB, including 260 Han people, 70 Uyghur people, 7 Muslim people and 4 people of Kazak ethnic minority group. The incidence of MB of the Uyghur and Han people was calculated respectively; incidence of MB in proximal, middle and distal segment of left anterior descending (LAD), the first diagonal branch (D1), the second diagonal branch (D2), obtuse marginal (OM), left circumflex (LCX) and right coronary artery (RCA) between two races were compared with Chi-Square test. Results Totally 341 patients had 439 MB, 332 in Han people, 92 in Uyghur people, 9 in Muslim people and 6 in Kazak ethnic minority group with 64-slice CT. There was no statistical significance of MB incidence between the Uyghur and Han people in coronary artery (P＞0.05), including the proximal, middle and distal segment of LAD. Conclusion The 64-slice CT can effectively detect MB with a high special resolution. There is no statistical significance of MB incidence between the Uyghur and the Han people in each coronary artery.
