Abstract:
Objective To observe the correlation between non-high density lipoprotein cholesterol levels and coronary artery disease(CAD),extent of angiographic coronary artery lesions and risk factors of CAD.Methods Serum total cholesterol ( TC ),triglyceride ( TG),high density lipoprotein cholesterol ( HDL-C ),low density lipoprotein (LDL-C),Lp(a),apoA-1 and apo B levels were measured in 282 patients with angiographic CAD meanwhile in 129 normal controls without angiographic coronary artery lesions.Non-HDL-C and LDL-C/HDL ratio was calculated.Logistic regression and partial correlation were used to find the correlation of serum non-HDL-C with CAD.Results Non-HDL-C[ (3.40 ± 1.01 ) mmol/L vs (3.08 ±0.65)mmol/L,P ＜0.05],LDL-C[ (2.63 ±0.84) mmo/L vs (2.40 ±0.54) mmol/L,P ＜0.05 ],TC[ (4.48 ± 1.07)mmol/L vs (4.23 ±0.69) mmol/L,P ＜0.05 ],and LDL-C/HDL ratio [ ( 2.52 ± 0.96) vs (2.21 ± 0.74 ),P ＜ 0.05 ] were significantly higher in the CAD group than in the control group.The four indexes also showed an increasing trend in the sequence of single,double and triple vessel lesions.Multivariate Logistic regression analysis found that among lipid factors,only non-HDL-C was independently associated with CAD.The results of partial correlation analysis demonstrated that non-HDL-C was positively correlated to the number of lesions( r =0.250,P ＜0.01 )and gensini score of CAD( r =0.116,P ＜0.05 ).Conclusion Non-HDL-C level is an independent risk factor for CAD and significantly correlated with the severity of CAD.
