Abstract:
Objective To investigate the comparison of volume of epicardium adipose tissue and calcification score on evaluating the degree of coronary artery stenosis(CHD).Methods Two hundred and ten cases with suspected coronary artery disease scanned by the 64 multi slice CT (MSCT) were selected as our subjects.One hundred and forty-five cases were diagnosed non coronary heart disease by with ＜ 50％ coronary artery stenosis by coronary angiography and served as non-CHD group.Other 55 cases were diagnosed as CHD with coronary artery stenosis ≥ 50％ and served as CHD group.The volume of epicardium adipose tissue and calcification score of all cases were calculated with Siemens definition workstation.Results The volume of epicardium adpose tissue and calcification score in patients of CHD group were (117.3 ± 57.6) cm3 and (413.3 ± 670.5) ％,significant different from that of non-CHD group ((100.0 ± 46.5) cm3,(36.2 ± 118.5).The differences were statistically significant (t =2.316,6.564; P ＜ 0.05,P ＜ 0.01).ROC curves showed that the sensitivity and specificity of calcification score were higher than the methods of volume of epicardium adipose tissue in terms of the diagnosis of stenosis and coronary artery disease.Conclusion Calcification score is proved to be a better method of predicting the coronary artery stenosis.
