目的探讨老年原发性高血压患者血压昼夜节律与颈动脉内膜-中膜厚度(IMT)的关系。方法90例老年原发性高血压患者均进行24小时动态血压、颈动脉超声检查。根据24小时动态血压监测结果将全部病例分为两组,夜间血压下降率≥10%为杓型组,<10%为非杓型组。结果非杓型组夜间收缩压(SBP)、夜间舒张压(DBP)比杓型组明显增高,非杓型组IMT明显大于杓型组,IMT与夜间SBP呈正相关。结论老年人高血压昼夜节律异常可导致IMT增加。
Objective To investigate the relationship between circadian rhythm of blood pressure and carotid intima - media thickness (IMT) in elderly patients with essential hypertension. Methods 90 cases of elderly patients with essential hypertension were carried out 24 hours ambulatory blood pressure, carotid ultrasound. According to the 24-hour ambulatory blood pressure monitoring results, all patients were divided into two groups. The nighttime blood pressure reduction rate was ≥10% for the dipper group and less than 10% for the non-dipper group. Results SBP and DBP in non-dipper group were significantly higher than those in dipper group, IMT in non-dipper group was significantly higher than that in dipper group, and IMT was positively correlated with SBP at night. Conclusion Abnormal circadian rhythm of hypertension in the elderly can lead to an increase of IMT.
