直立性低血压(orthostatic hypotension,OH)是老年人及神经系统疾病患者常见的血流动力学异常,与晕厥、跌倒及脑灌注不足密切相关。传统的间歇性袖带电子血压测量难以捕捉体位改变瞬间的快速血压波动,限制了对OH动态特征的准确评估。无创逐搏血压监测技术可实现高时间精度的连续血压监测,而经颅多普勒超声(transcranial Doppler,TCD)可实时反映脑血流速度变化。二者联合应用,可动态反映体位变化过程中血压下降与脑灌注改变的关联,从而为OH分型、相关发病机制探讨及脑血流调节功能评估提供重要依据。本综述围绕无创逐搏血压监测联合TCD在OH研究与临床评估中的应用进展,重点阐述该联合方法的技术优势、主要研究发现及其临床应用价值,以期为OH的精准评估及相关机制研究提供参考。
Orthostatic hypotension(OH) is a common hemodynamic abnormality in the elderly and in patients with neurological disorders,and it is closely associated with syncope,falls,and cerebral hypoperfusion. Conventional intermittent cuff-based blood pressure measurements are unable to capture the rapid blood pressure fluctuations that occur immediately after postural change,thereby limiting accurate assessment of the dynamic characteristics of OH. Noninvasive beat-to-beat blood pressure monitoring can realize continuous blood pressure measurement with high temporal resolution,while transcranial Doppler(TCD) can provide real-time assessment of cerebral blood flow velocity. The combination of these two techniques can dynamically reflect the relationship between blood pressure decline and cerebral perfusion changes during postural change and thus provide an important basis for the classification of OH,the exploration of its underlying mechanisms,and the assessment of cerebral blood flow regulation. This article reviews the advances in the application of noninvasive beat-to-beat blood pressure monitoring combined with TCD in the research and clinical evaluation of OH and elaborates on the technical advantages,major research findings,and clinical application value of this combined approach,in order to provide a reference for the precise assessment and mechanistic investigation of OH.
