老年人超敏C-反应蛋白和颈动脉斑块与冠脉病变的相关性

目的：探讨超敏C-反应蛋白水平和颈动脉斑块与冠脉病变严重程度的关系。方法：选择因心绞痛行冠状动脉造影的住院患者140例,根据冠脉造影结果分为单支病变组（11例）、双支病变组（18例）、多支病变组（71例）和对照组（40例）。用彩色多普勒超声仪测量颈总动脉内膜中层厚度（intima-media thickness,IMT）及颈动脉分叉处IMT,记录颈动脉斑块的位置、数量,并测定血清超敏C-反应蛋白水平。结果：与对照组比较,多支病变组颈总动脉IMT、分叉处IMT和斑块积分明显增高,差异有统计学意义（P〈0.01）。与对照组及单支病变组比较,多支病变组颈总动脉IMT增厚比例明显增高,差异有统计学意义（P〈0.05）。超敏C-反应蛋白浓度在单支病变组、双支病变组、多支病变组,其浓度依次增高（P〈0.01）。结论：超敏C-反应蛋白水平和颈动脉粥样斑块与冠脉病变严重程度关系密切,有助于临床上预测老年冠心病患者冠脉病变的严重程度。

Relationship between plasma high-sensitivity C reactive protein level, carotid artery atherosclerosis and coronary artery lesion in old-aged patients

Objective: To explore the relationship of high-sensitivity C reactive protein,carotid artery atherosclerosis and coronary artery lesion.Methods: Coronary angiography were performed in 140 patients with angina pectoris.According to the results of coronary angiography,all patients were divided into 4 groups,one-vessel lesion group(n=11),two-vessel lesion group(n=18),multi-vessel lesion group(n=71) and control group(n=40).The intima-media thickness(IMT) of carotid artery and the degree of carotid atheroscleros...
