Advances in pulse wave velocity to evaluate vascular elasticity under ultrasound scanner / 中国医学装备

ABSTRACT

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.
