高龄老年人原发性高血压与动脉粥样硬化的关系

Study between essential hypertension and carotid atherosclerosis in aged people

目的探讨高龄老年人血压与动脉粥样硬化程度的关系。方法住院高龄老年人136例,年龄80～95岁。其中原发性高血压组92例,血压正常组44例,行颈动脉超声检测,比较两组动脉粥样硬化程度。结果高血压组与血压正常组在内膜中层厚度方面比较差异有统计学意义[(1.10±0.35)mm vs(0.96±0.29)mm,P<0.05],两组斑块数比较差异有统计学意义。结论高血压可使颈动脉内中膜增厚及斑块数增多,加重动脉粥样硬化。

Objective To study the relationship between essential hypertension and carotid atherosclerosis in the aged patients.Methods 136 patients aged 80-95 were selected.They were divided into two groups of 92 cases with essential hypertension and 44 cases with normal hypertension.The degree of carotid atherosclerosis was compared between two groups through ultrasonic testing.Results There were significant differences in degree of carotid intima-media thickening and the numbers of plaque between essential hypertension group and normal hypertension group[（1.10±0.35）mm vs（0.96±0.29）mm,P0.05].Conclusions The blood pressure increase the degree of carotid intima-media thickness and the numbers of plaque,and accelerate carotid atherosclerosis.
