Abstract：Objective To evaluate the morphological characteristics of myocardial bridge mural coronary artery (MBMCA) by 128 slice spiral CT coronary angiography, and to analyze the relationship between atherosclerotic lesion of proximal coronary artery. Methods From March 2015 ~ March 2017, 79 pure MBMCA patients without atherosclerosis were selected as control group, another 79 proximal coronary myocardial bridge patients with atherosclerosis were selected as observation group. Patients in both groups were examined with 128-slice spiral CT coronary angiography. Basic clinical data such as age, gender, and heart rate, the coronary artery detection indexes (thickness and length of mural coronary artery myocardial bridge and smooth mural coronary artery on both ends, wall proximal coronary artery angulation, distal coronary artery wall into the angle of mural coronary artery, the angulation) levels, and through the multi-factor Logistic regression analysis MBMCA and coronary artery in the relationship between atherosclerotic lesions were compared. Results The age of observation group was significantly higher than that of the control group (P＜0.05). There was no statistically significant difference in gender, heart rate, course of disease, hypertension and diabetes (P＞0.05). The smooth mural coronary artery wall length, coronary artery ends number accounted rate of observation group were significantly lower than those of control group. And mural coronary artery distal coronary artery wall angle, angle of the total number of people on both ends of observation group were significantly higher than those of control group, the difference was statistically significant (P＜0.05). After multivariable logistic regression analysis available: age (OR=1.421, P=1.421), distal coronary artery wall Angle (OR=2.147, P=2.147) and coronary artery wall Angle on both ends (OR=2.579, P=2.579) were independent risk factors of the wall of the proximal coronary atherosclerosis, and the smooth mural coronary artery on both ends were protective factors (OR=2.736, P=2.736). Conclusion 128 slice spiral CT coronary angiography can effectively evaluate the myocardial bridge wall coronary artery morphological characteristics and coronary atherosclerotic lesions in the proximal segment, and they are closely related, which is worth for attention.
