高血压患者动态血压与动脉顺应性的关系

The relationship between ambulatory blood pressure and large arterial compliance in essential hypertension

对５６例正常血压和８９例高血压患者２４小时动态血压参数与大动脉顺应性之间的相关性进行观察，发现夜间血压下降率＜１０％即血压昼夜节律消失的高血压患者大动脉顺应性显著低于夜间血压下降率＞１０％者（Ｐ＜０．０１）。血压负荷值、白昼及夜间收缩压均与动脉顺应性呈负相关，但夜间更为明显，提示持续血压升高，夜间血压水平与血压昼夜节律状况是影响大动脉顺应性的重要因素。

The relationship between ambulatory blood pressure and large arterial compliance were investigated in 56 healthy normotensives and 89 patients with essential hypertension.The results showed that large arterial compliances in hypertensive patients whose lowering rate of nighttime blood pressure were more than 10% (day-night blood pressure rhythm disappeared)being significantly lower than hypertensive patients whose lowering rate of nighttime blood pressure were less than 10%(P<0.01).The blood pressure load value, daytime and nighttime systolic blood pressure were inversely correlated with arterial compliance, but more significant in the night time. the results suggest that persistent high blood pressure, nighttime blood pressure leveland the day-night blood pressure rhythm were important contributors to large arterial compliance.
