Abstract:
Objective To evaluate the clinical value of 64 slice spiral CT in coronary plaque stability.Methods 50 patients with coronary heart disease (CHD) who received coronar artery CT angiography were selected.The situation of coronary artery plaque by 64 slice spiral CT coronary angiography were obseirved.The distribution of different types of plaque in patients with different grades of angina pectoris was analyzed.The CT value of coronary artery and the value of CT value of coronary artery plaque in delayed phase were measured and compared.Results 64 slice spiral CT coronary angiography showed a total of 85 plaques.The left anterior descending branch 29,left circumflex branch of the 26,the left main trunk of the 15,the right crown of the 15.There were 30 types Ⅰ plaques,25 type Ⅱ plaques,and type Ⅲ plaques of 30 sites.Comparison of different types of plaques in patients with different grade,the difference was statistically significant (x2-=14.465,P ＜ 0.05).Comparison between the groups,the proportion of different types of plaque in patients with angina pectoris and different grade,the difference was statistically significant (x2 =8.878,8.892,all P ＜ 0.05).The differences of CT value [(52.1 ± 12.6) Hu vs.(29.1 ± 7.7) Hu vs.(41.6 ± 10.9) Hu] and CT value of coronary artery plaque[(13.4 ± 3.9) Hu vs.(7.7 ± 1.6) Hu vs.(10.4 ± 2.9) Hu] in patients with grade Ⅰ,Ⅱ and Ⅲ were statistically significant (F =23.462,18.289,all P ＜ 0.05).The CT value and CT value of coronary artery plaque in the patients with angina pectoris were the lowest.Conclusion In the evaluation of coronary plaque stability,64 row spiral CT has high application value.
