Abstract

The cardio-ankle vascular index (CAVI) is superior to traditional methods of measuring arterial stiffness. However, its application in clinical practice has lagged behind the science. This study aimed to (1) examine its test-retest reliability and agreement between repeated measurements, (2) identify the correlation with fatigue and sleep quality, and (3) compare the CAVI values of the bilateral sides of people with stroke, and those of stroke survivors with and without fatigue. Participants (n = 67) were assessed using the CAVI, Fatigue Assessment Scale, and Pittsburgh Sleep Quality Index. The test-retest reliability ranged from 0.77 to 0.86. The Bland-Altman plots showed good agreement between test and retest. The standard error of measurement ranged from 0.59 to 0.66. The minimal detectable change ranged from 1.15 to 1.29. The CAVI values of the bilateral sides correlated with fatigue and those at the paretic side correlated with sleep quality. The CAVI values of the paretic side were higher than those of the non-paretic side in people with stroke. Stroke participants with fatigue had higher CAVI values than those without fatigue. CAVI has good test-retest reliability and agreement between repeated measurements for clinical use.

心-踝血管指数:中风患者测试-重测的可靠性和一致性。
心踝关节血管指数(CAVI)优于传统的动脉僵化测量方法。然而,它在临床实践中的应用却落后于科学研究。本研究旨在:(1)检查其重复测量的可靠性和一致性;(2)确定其与疲劳和睡眠质量的相关性;(3)比较中风患者双侧的 CAVI 值,以及有疲劳和无疲劳的中风幸存者的 CAVI 值。使用 CAVI、疲劳评估量表和匹兹堡睡眠质量指数对参与者(67 人)进行了评估。测试再测可靠性为 0.77 至 0.86。布兰德-阿尔特曼图显示测试与重测之间的一致性良好。测量的标准误差在 0.59 至 0.66 之间。最小可检测变化范围为 1.15 至 1.29。双侧的 CAVI 值与疲劳相关,而瘫痪侧的 CAVI 值与睡眠质量相关。中风患者瘫痪侧的 CAVI 值高于非瘫痪侧。有疲劳感的中风患者的 CAVI 值高于无疲劳感的患者。CAVI 具有良好的重复测试可靠性和重复测量之间的一致性,可用于临床。
