Abstract:
Objective To analyze the imaging findings of coronary angiography using 64-slice row CT and investigate the difference of coronary artery's morphological characteristics between Uygur and Han populations.Methods A retrospective study was made to coronary CT angiographic images of 88 Uygur cases matched with 88 Han cases.The data were analyzed with X~2 test and paired Wilcoxon test.Results The coronary CT angiographic findings were different between Uygur population and Han population in the following aspects: there were 62, 18, and 8 cases with the left coronary artery originating from intra-sinus, para-sinus and extra-sinus location respectively in Uygur population, while there were 73, 14, and 8 cases in Han population respectively (t=8319, P<0.05).And there were 78,7, and 3 cases with the right coronary artery originating from intra-sinus, para-sinus and extra-sinus location respectively in Uygur population, while there were 82, 1 and 1 case respectively in Han population (t=6936, P<0.05).The incidence of the sharp marginal branch were 52 (52.09%) and 67 (76.13%) in the two populations respectively (X~2=5.8381, P<0.05).The cases with various malformations of coronary arteries were 16 and 6 cases in the two populations respectively(X~2 =5.1948,P<0.05).The cases with LCA variations were 28 and 49 cases in the two populations respectively(t =2692,P<0.05) and the number with RCA variations were 33 and 27 cases in the two populations respectively(2 =968,P<0.05).Conclusions There are lots of differences of the coronary artery morphology between the Uygur and Han populations.Firstly, these differences may be related to different patterns in coronary angiography.Secondly, these differences may be related to differences between Uygur and Han populations in the incidence and severity of coronary heart disease.
