Abstract:
Objective To study the relationship between plasma level of tissue factor(TF)and severity of coronary heart disease(CHD).Methods Coronary angiography was performed in 237 patients with suspected CHD,with 149 diagnosed as CHD and 88 excluded.Seventy of stenosis of coronary arteries (CA)was evaluated by modified Gensini score on the basis of angiographic imaging.Blood glucose,serum levels of total cholesterol(TC),triglycerides(TG),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),lipoprotein(a)[Lp(a)],uric acid,high sensitivity C-reactive protein(Hs-CRP),fibrinogen(FIB)and plasma level of TF were determined for all the subjects.Relationship between plasma level of TF and severity of pathological changes in CA was evaluated by linear correlation and multiple regression analyses for controlling other relevant factors.Results Plasma level of TF in patients with CHD[(138±39)ng/L]was significantly higher than that in controls[(61±19)ng/L](P＜0.01).Plasma level of TF obviously correlated with severity of pathological changes in CA(r=0.710,P＜0.01).Partial correlation analysis showed a positive correlation between plasma TF and severity of pathological changes in CA,independent of other potential influential factors,with a partial coefficient of correlation of 0.509(P＜0.01).Multiple stepwise regression analysis indicated that plasma level of TF associated with severity of pathological changes in CA,as well as with diabetes,LDL-C,Lp(a),Hs-CRP and FIB,with coefficients of correlation of 0.172,0.180,0.147,0.308 and 0.175,respectively(P＜0.05).Conclusion Elevated plasma level of TF may be one of important risk factors for CHD,which reflects severity of pathological changes in CA.
