血脂比值和单项血脂与冠脉狭窄程度的相关分析

Correlation Studying on lipid and CHO/HDL and the Degree of Coronary Artery Stenosis of CAD

目的探讨冠心病患者单项血脂及血脂比值与冠脉狭窄程度关系。方法对已行冠状动脉造影的阳性病人(最少有一支血管狭窄≥50%)的单项血脂和比值并与其冠脉造影所得结果进行相关分析。结果在单项血脂中,TG、CHO、LDL均与冠脉狭窄程度呈正相关,而HDL与冠脉狭窄程度呈负相关。在血脂比值中,CHO/HDL和TG/HDL值均随冠脉狭窄程度加重而增加,且差异有显著性意义。CHO/HDL和TG/HDL比值比单项血脂反映CAD的敏感度更高。结论对于CAD患者,血脂比值较单项血脂反映冠脉狭窄程度更敏感。

Objective To study the relationship of individual lipid and cholesterol/high density lipoprotein （CHO/HDL） and the degree of coronary artery stenosis of coronary atherosclerotic heart disease （ CAD）. Methods 227 patients with positive results in coronary angiogram （ at least one artery is more narrow than 50 % ） were recuited, and investigated correlation of the individual and blood lipid ratio and results by coronary angiography. Results The studying showed a positive correlation between the degree of coronary ＇artery stenosis and TG, CHO, LDL, and a negative correlation between the degree of coronary artery stenosis and HDL . In the study of blood lipid ratio , there were positive correlation betweenCHO/HDL and TG/HDL and the degree of coronary artery stenosis. The ratio of CHO/HDL and TG/HDL can understand the of coronary artery stenosis more easy than individual blood lipids. Conclusion For CAD patiends , blood lipid ratio reflect Degree of Coronary Artery Stenosis of CAD morn sensitive and early than individual blood lipid
