超声测量脉搏波传导速度评估血管弹性研究进展

摘要

心血管疾病是我国居民的首位死亡原因，血管弹性是心血管病死率的重要独立预测因子，而脉搏波传导速度(PWV)是最常见的超声测量指标，在临床中得到了广泛的运用。传统测量PWV的方法存在动脉走行不明确、分支影响多等弊端，且只能获得全局、平均的PWV，目前局部脉搏波传导速度的超声测量在血管弹性研究中有着重要的作用，常用的局部脉搏波传导速度检测方法有血管回声跟踪技术、超高速成像技术及脉搏波成像技术。为此对脉搏波传导速度评估血管弹性研究进展进行综述。%Cardiovascular disease is the first cause of death in Chinese residents. Arterial elasticity is an important and independent predictor for mortality of cardiovascular disease, and pulse wave velocity (PWV) is the most frequently used measurement index. It has been widely used in clinical practice. Traditional methods detecting PWV have some disadvantages, such as arteries distribution not clear, branch affect and only obtain global and average, instead of regional PWV. Now, the measurement of local pulse wave velocity has played an important role in the study of arterial elasticity. The common methods of detecting regional pulse wave velocity include echo tracking technique, UltraFast imaging technique and pulse wave imaging technique. This article reviews the recent advances in pulse wave velocity evaluating vascular elasticity.
