门诊血压监测 (ABPM) 显示,当患者站立或移动时,与坐着相比,白天血压读数更高. 这种姿势的差异可能会影响高血压的诊断.
科学领域:
- 心脏病学 心脏病学
- 高血压研究 高血压研究
- 生物医学工程 生物医学工程
背景情况:
- 目前的门诊血压监测 (ABPM) 准则缺乏有关患者姿势的建议.
- 最近的身体活动,特别是站立或移动与坐着对ABPM读数的影响还不清楚.
研究的目的:
- 调查最近站立或移动与坐着如何影响通过ABPM获得的平均白天血压测量.
- 用ABPM确定姿势和活动对高血压变异性和诊断的影响.
主要方法:
- 利用从一项涉及办公室血压升高的办公室办公室工作人员的临床试验的基线数据.
- 雇佣ABPM与SunTech医疗奥斯卡2监控器,每30分钟进行一次读数.
- 测量并发的姿势 (坐着与非坐着) 和活动 (步骤) 使用大腿佩戴的加速度计.
- 应用线性回归来评估血压的变化,通过站立和步骤解释读数之前的读数.
主要成果:
- 站着的时间和读数前的步数解释了白天静缩血压 (SBP) 的17%和白天静缩血压 (DBP) 的14%的变化.
- 坐着的血压读数 (130.8/79.7 mmHg) 显著低于非坐着的读数 (137.8/84.3 mmHg).
- 平均白天高血压 (≥135/85 mmHg) 的患病率在非坐着的读数 (70.3%) 与坐着的读数 (38.7%) 相比,显著更高.
结论:
- 与坐着相比,在站立和运动期间,白天的血压系统地升高.
- 每日活动模式和姿势的变化可以显著影响基于白天ABPM读数的高血压诊断准确度.
- 可能需要进一步的研究来将活动和姿势数据纳入ABPM解释.

Factors affecting Blood pressure
Physiological Factors:
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
