计算脉搏波传导速度(pulse wave velocity,PWV)需要估算脉搏波移动距离,但目前估算距离的方法并未标准化。该文旨在探讨在血液透析(hemodi-alysis,HD)患者中,采用不同的距离测量方法对PWV和心血管疾病死亡率的相关性是否有影响。方法 :对98例慢性HD患者使用3种不同距离测量方法测定其PWV水平,这3种方法分别为
The calculation of pulse wave velocity (PWV) requires estimation of pulse wave travel distance, but current methods of estimating distance are not standardized. The aim of this study was to investigate whether different measures of distance in hemodi-alysis (HD) patients affect the association between PWV and cardiovascular mortality. METHODS: PWV levels were measured in 98 chronic HD patients using three different distance measures, which were
