目的了解原发性高血压血压变异性(BPV)对颈动脉粥样硬化的关系。方法对32例颈动脉粥样硬化的原发性高血压患者(硬化组)和30例无颈动脉粥样硬化的原发性高血压患者(无硬化组)进行动态血压监测,对比分析24 h平均收缩压(24hsBP)、平均收缩压标准差(24hSSD)、平均舒张压(24hDBP)和平均舒张压标准差(24hDSD)。结果硬化组的观察指标均高于无硬化组,差异有统计学意义(P<0.05)。结论动脉粥样硬化的原发性高血压患者其24 h白昼和夜间平均血压高,24 h白昼和夜间血压变异性大。
Objective To investigate the relationship between essential hypertension (BPV) and carotid atherosclerosis. Methods Thirty two patients with carotid atherosclerosis (sclerosis group) and 30 patients with primary carotid atherosclerosis (non-sclerosis group) underwent ambulatory blood pressure monitoring. Mean systolic blood pressure (24hsBP), mean systolic blood pressure standard deviation (24hSSD), mean diastolic blood pressure (24hDBP) and mean diastolic blood pressure standard deviation (24hDSD). Results of the observation group sclerosis were higher than non-sclerosis group, the difference was statistically significant (P <0.05). Conclusions In patients with atherosclerosis, the mean high blood pressure at 24 h of daytime and at night is high, and the variability of blood pressure at daytime and at night is high at 24 h.
