Abstract:
Objective To study the characteristics of CT images of myocardial bridge(MB)in patients with atherosclerosis.Methods CTA images of MB in 129 patients with atherosclerosis were studied.Another 109 patients without atherosclerosis,in the diagnosis of MB were used as control.The type,age,thickness of MB,length of mural coronary artery and end systolic diameter of mural coronary artery were compared between the two groups.Results In the study group,78 cases (60.5%)were superficial type,51(39.5%) were deep type.While in the control group,70(64%)cases were superficial type and 39(36%)were deep type.There was no significant difference between the two groups.The age,thickness of MB,length of mural coronary artery and end systolic diameter of mural coronary artery in each group were 57.01±10.17 years old,(3.15±1.66)mm,(20.43±7.38)mm,(1.16±0.25)mm and 48.36±9.11 years old,(1.95±1.77)mm,(21.07±6.69)mm,(2.07±0.81)mm.These parameters had significant differences between the two groups except the length of mural coronary artery (P>0.05).Conclusion The MB of the study group is thicker than the control group,and the mural coronary artery diameter of the former is narrower than that of the latter.
