Abstract:

Objective To investigate the correlation between serum biochemical parameters and the degree of coronary artery stenosis in patients with coronary heart disease. Methods A total of 574 patients with coronary heart disease undergoing coronary angiography were enrolled from 3 Grade A Class 3 hospitals in Shanghai,Wuhan and Fuzhou. The coronary artery stenosis data obtained during percutaneous coronary intervention(PCI)were recorded and quantified to calculate Gensini score. Clinical data and the results of serum biochemical parameters,including total bilirubin(TB),direct bilirubin(DBil),total protein(TP),albumin(Alb),alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyltransferase(GGT),lactate dehydrogenase(LDH),fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),lipoprotein(a)[Lp(a)],apolipoprotein A1(apo A1),apolipoprotein B(apo B) and high-sensitivity C-reactive protein(hs-CRP),were collected. Logistic regression analysis was used to assess the correlation between each parameter and the degree of coronary artery stenosis. Results Compared to low Gensini score group,the proportion of males and TP,Alb,ALT,AST,FPG,HDL-C,Lp(a),apo A1,apo B,hs-CRP levels in high Gensini score group had statistical significance(P<0.05),while the other parameters had no statistical significance(P>0.05). Logistic regression analysis showed that Alb decreasing,AST increasing,FPG increasing,HDL-C decreasing,Lp(a) increasing and male were risk factors for coronary artery stenosis [odds ratios(OR) were 0.932,1.011,1.121,0.299,1.005 and 1.753;95% confidence intervals(CI) were 0.886-0.980,1.002-1.020,1.024-1.227,0.143-0.624,1.002-1.008 and 1.110-2.767,respectively]. Conclusions FPG and Lp(a) are risk factors for predicting the degree of coronary artery stenosis in patients with coronary heart disease,and they can be used for preliminary judgment. Whether AST,Alb and HDL-C can be used as the predictors of coronary artery stenosis remains to be further studied.
