中心动脉压超压积分的研究进展

Research Progress on Excess Pressure Integral of Central Arterial Pressure

中心动脉压(CAP)是指升主动脉根部承受的侧压力,可分为收缩压、舒张压、脉压,是反映脏器血液灌注的重要指标。超压积分是近年来随着相关技术成熟与数学模型建立而提出的一种新型血管损伤评价指标,可反映心脏每次搏动中的额外做功,对心血管事件和多种脏器功能损伤具有预测价值。本文主要综述了CAP超压积分的定义及其临床价值,旨在为超压积分的临床应用提供参考。

Central arterial pressure means lateral pressure of ascending aortic root,can be divided into systolic pressure,diastolic pressure and pulse pressure,is one of important indicators for reflecting viscera blood perfusion status. Excess pressure integral（ XSPI） is one of the novel markers for vascular damage. It is based on the relevant technical maturity and mathematics model establishment in recent years. XSPI can reflect surplus work in each cardiac cycle,has certain predictive value on occurrence of cardiovascular events and multiple organs dysfunction. This paper reviewed the definition and clinical value of XSPI of Central arterial pressure,in order to provide a reference for clinic.
