Abstract:
Objective: To investigate the value of double source CT(DSCT)in the diagnosis of myocardial bridge(MB)and analyze the correlation of MB-associated coronary atherosclerotic plaque with age.Methods: A total of 417 patients suspected of coronary artery disease(CAD)were divided into a young group(n=137,30-44 yrs),a middle-aged group(n=197,45-59 yrs) and an old group(n=83,60-84 yrs),subjected to DSCT coronary angiography,and analyzed for the differences in the incidence of MB and coronary atherosclerosis.Results: Altogether 76 cases(18.2%) were diagnosed as MB,10(13.2%) in the young,36(47.4%) in the middle-aged and 30(39.5%) in the old group.Of the MB patients,41(53.9%) were complicated with coronary atherosclerotic plaque,2(20.0%) in the young,17(47.2%) in the middle-aged 22(73.3%) in the old group.There were significant statistical differences in the incidence and the nature of coronary atherosclerotic plaque among the 3 groups(P
