老年单纯收缩期高血压患者的血压对颈动脉粥样硬化的影响

Influence of blood pressure of the elderly patients with isolated systolic hypertension on carotid atherosclerosis

目的探讨老年单纯收缩期高血压对颈动脉粥样硬化的影响。方法上海市第二人民医院住院的老年高血压患者90例,其中单纯收缩期高血压患者45例,非单纯收缩期高血压患者45例,均做颈动脉超声检测,比较2组颈动脉粥样硬化发生的情况。结果老年单纯收缩期高血压患者颈动脉内膜中层增厚及粥样斑块的发生率与老年非单纯收缩期高血压患者相比更高,差异有统计学意义(P<0.05),提示前者病变更加严重。结论老年病患者的收缩压是比舒张压更强的致动脉粥样硬化的预测因子。

Objective To explore the influence of blood pressure of the elderly patients with isolated systolic hypertension on carotid atherosclerosis.Methods A total of 90 elderly patients with high blood pressure in our hospital were included in the study.There were 45 isolated systolic hypertension patients and 45 non-isolated systolic hypertension patients.All received carotid ultrasound detection,and incidence rates of carotid atherosclerosis in the two groups were compared.Results The incidence rate of elderly patients with isolated systolic hypertension in carotid endarterectomy membrane thickening and atheromatous plaque was still higher than that of the non-isolated systolic hypertension patients.The differences were statistically significant（P〈0.05）,which indicated that the pathological changes of the former were more serious.Conclusion Systolic blood pressure of elderly patients is a stronger predictor than diastolic blood pressure to cause atherosclerosis.
