老年冠心病患者颈动脉硬度与冠状动脉造影的相关性研究

Relationship between carotid stiffness and coronary angiography in elderly patients with coronary heart disease

目的检测老年冠心病患者的颈动脉硬度，探讨其与冠心病的相关性及在老年冠心病诊断中的价值。方法选择35例老年冠心病患者进行冠状动脉（冠脉）造影，并根据其结果进行冠脉病变评分，同时检测颈动脉硬度；并与高血压组、高血脂组和健康老年组比较。结果老年冠心病组的颈动脉紧张度（8．15±1．54）、动脉扩张性（0.34±0．07）及动脉僵硬度（640．51±150．98）与其他组比较，差异有统计学意义（P〈0.05或P〈0.01），且与冠脉病变积分呈明显相关（P〈0.05或P〈0．01）。结论老年冠心病患者的颈动脉硬度指标变化程度与冠脉狭窄程度相平行，可以作为预测冠心病的发生、发展及严重程度的一个指标。

Objective To investigate the relationship between carotid stiffness and coronary angiography in elderly patients with coronary heart disease（CHD）. Methods Thirty-five elderly patients with CHD who underwent coronary angiography were enrolled in the study. The carotid stiffness was measured by ultrasound, the results were compared with those in hypertension group, hyperlipemia group and healthy elderly group. Results There were significant differences in carotid tensity （8.15±1.54）, arterieetasis （0.34 ± 0. 07） and carotid stiffness（640.51 ± 150. 98）of elderly patients with CHD compared to other groups（all P〈0.05 or P〈0.01）. There was significant correlation between coronary angiography score and carotid stiffness in elderly patients of CHD（P〈 0. 05 or P〈0. 01）. Conclusions There is close relationship between carotid atheroselerosis and coronary atherosclerosis in elderly patients with CHD.
