高血压患者中活动与血压和心率的相关性探讨

The relationship of electronically monitored physical activity to blood pressure and heart rate in hypertensive patients

目的了解高血压个体中活动与收缩压、舒张压以及心率的相关性,同时了解高血压群体中活动对收缩压、舒张压以及心率的影响。方法使用动态血压监测仪对42例高血压患者和21例健康志愿者进行24h的动态血压监测,每30min测量一次血压,同时使用静息活动监测仪对患者日常活动进行监测,把血压测量前5min的平均活动值与血压值和心率值进行相关性分析,从而了解高血压个体和群体中活动与血压和心率的关系。结果对多数高血压个体而言,活动与血压和心率成正相关,但是相关的程度,个体间相差很大;在高血压群体中,白天活动以及24h的活动与血压和心率间均有显著相关性。结论静息活动监测仪监测的日常活动对高血压患者的收缩压、舒张压以及心率均有重要影响。

Aim To study the relationship between the electronically monitored physical activity and the blood pressure and heart rate in hypertensive subjects. Methods Forty-two hypertensive patients and twenty-one healthy volunteers wore an ambulatory blood pressure monitor and a wrist actigraph simultaneously. Each average activity for 5 min was determined before each valid blood pressure reading. Activity was correlated with blood pressure and heart rate using Pearson＇s correlation coefficient in each patient individually and overall group. Results For individual patients, positive correlation was found between activity levels and blood pressure and heart rate to most patients, but there was marked variation in the degree of correlation. Strong positive correlation was found between group day and 24 h average activity and blood pressure and heart rate. Conclusion These findings indicate that physical activity has great influence on blood pressure and heart rate.
