摘　　要：目的探讨多层螺旋CT评价老年血脂异常与冠状动脉狭窄程度的相关性。方法选择300例60岁以上由于胸痛首次入院疑诊冠心病患者,其中未合并血脂异常患者77例作为对照组,合并血脂异常患者223例作为观察组,并依据血脂异常危险分层分为低危组、中危组、高危组。应用64层螺旋CT冠状动脉成像技术,采用Gensini积分评价冠状动脉病变程度,并计数冠状动脉病变的支数。采用单因素方差分析及Pearson相关性分析观察老年血脂异常与冠状动脉狭窄程度间的关系。结果中危、高危组狭窄程度评分及狭窄数量均高于对照组(P<0.05);低危组与对照组比较差异无统计学意义(P>0.05)。组间比较,除对照组与低危组外,其他各组间差异均具有统计学意义(P<0.05)。结论老年血脂TC、TG、LDL-C、HDL-C与冠状动脉狭窄支数、程度相关;老年血脂异常危险分层与冠状动脉狭窄支数、程度相关。【Objective】 To investigate the correlation between multi-slice spiral CT to evaluate dyslipidemia of elderly population and the degree of coronary artery stenosis. 【Methods】 Select 300 cases over 60years patients first in admitted to hospital since pain in the chest with suspected coronary artery disease, no dyslipidemia patients（n =77 cases） as a control group, dyslipidemia patients（n =223 cases） as the observation group, and based on risk stratification of dyslipidemia, divided them into low-risk group, middle-risk group,high-risk group. Application of 64-slice spiral CT coronary imaging technology, evaluated coronary artery lesions by the Gensini score and count the counts of coronary artery disease. Univariate analysis of variance and Pearson correlation analysis to observed the relationships of dyslipidemia in elderly patients and the degree of coronary artery stenosis. 【Results】 The degree of stenosis and the counts of coronary artery in middle-risk group and high-risk group are higher than control group（P〈0.05）, there is no different between lowrisk group and control group（P〉0.05）. The comparison among groups are differences（P〈0.05）, except control group and low-risk group. 【Conclusion】 Lipid levels such as TC, TG, LDL-C and HDL-C have relevant with count and extent of coronary artery stenosis in elderly patients. Risk stratification of dyslipidemia in elderly patients have relevant with counts and the degree of coronary stenosis.
