24h动态血压各项指标及其意义

动态血压监测帮助临床医师可以获知以下内容:血压变异性,与患者自主神经调节功能及压力反射的敏感性有关,可预测靶器官受损程度;晨峰血压,晨起交感神经兴奋性及体液调节异常造成血压急剧升高,达一定数值将对心、脑血管造成危害;实时血压数值,单纯收缩期高血压/脉压增大多见于老年高血压患者,在高血压治疗过程可能出现"J曲线效应",准确得到血压数值及正确用药将决定患者预后。

Parameters of the 24 Hours Ambulatory Blood Pressure Monitoring and the Significance

The ambulatory blood pressure monitoring(ABPM)is conducted to obtain the following parameters:blood pressure variability(BPV),which is related to autonomic nervous system(ANS)and baroreflex sensitivity(BRS),can be used to predict the severity of target organ damage;morning blood pressure surge(MBPS):increased sympathetic tone and abnormally high body fluids cause blood pressure significantly elevating,which will damage the blood vessels of the brain and heart;real-time blood pressure:isolated systolic hypertension(ISH)/pulse pressure increases is particularly common in the elderly,J-curve phenomenon might appear in the treatment of hypertension.So an accurate blood pressure and a correct medication play an important role in the prognosis of hypertension patients.
