摘　　要：为探讨动态血压负荷在老年高血压病分期中的价值，采用无创性动态血压监测系统，记录老年正常血压16例和高血压Ⅰ期25例、Ⅱ期34例、Ⅲ期27例患者24小时动态血压负荷值。结果发现，高血压各组血压负荷依次递增。Ⅰ期组与正常组比较，24小时及昼夜血压负荷均存在非常显著性差异（P＜0．001）；Ⅱ期组与Ⅰ期组比较，夜间血压负荷明显增加（P＜0．001）；Ⅲ期组与Ⅱ期组比较，24小时收缩压负荷存在显著性差异（P＜0.01），且血压负荷值主要分布在异常血压次高段。血压负荷反映异常血压出现的时间、频率和血压段，在老年高血压病分期中起重要作用。Aim: To investigate the value of ambulatory blood pressure load in elder hypertension stage.Methods: Ambulatory blood pressure load during 24 h was measured by ambulatory blood pressure monitoring in 16 cases of normal blood pressure, 25 patients with hypertension at stage one, 34 patients with hypertension at stage two, and 27 patients with hypertension at stage three in elder.Results: The blood pressure load increased along with the different hypertension stage. The difference of blood pressure load between group stage one and normal group was remarkable(P<0. 001) during 24 h,day and night. Blood pressure load of group stage two was significantly increased than group stage one at night (P<0.001). Systolic blood pressure load was significantly different between group stage three and group stage two(P<0.01) during 24 h. In addition, the blood pressure load of group stage three was mainly presented at the second high period of abnormal blood pressure.Conclusion: Blood pressure load might reflect the time, the frequence, and the extent of abnormal blood pressure. Ambulatory blood pressure load takes important effect in elder hypertension stage.
