Abstract

Frailty has been described as a clinical state of vulnerability to stress, consequence from decline of resilience and physiological reserves and progressive decline on ability of homeostasis maintenance. The aim of this study was to evaluate the complexity of R-R intervals (RR) in resting supine (REST) and standing (STAND) position in 3 groups: frail, pre-frail and non-frail. Eighty older people (60-94 years old) were divided into frail group (n = 6), pre-frail (n=36) and non-frail group (n=38). The RR series were recorded at REST and during STAND for 10 minutes in each position. Short sequences of RR were analyzed by conditional entropy (CE) and approximate entropy (ApEn). Position, group and interaction effects were evaluated by two-way repeated-measures ANOVA. CE indicated only position effect while ApEn showed only group effect. ApEn seems to be more suitable for assessing changes in the complexity in frailty syndrome.

虚弱综合征中心血管震荡的短期复杂性

虚弱被描述为一种易受压力影响的临床状态，是恢复力和生理储备下降以及维持体内平衡能力逐渐下降的结果。本研究的目的是评估3组:体弱、体弱前期和非体弱患者仰卧休息(REST)和站立(STAND)姿势的R-R间隔(RR)的复杂性。80例老年人(60 ~ 94岁)分为体弱组(n= 6)、体弱前期组(n=36)和非体弱组(n=38)。分别在休息和站立时记录RR序列，每个体位记录10分钟。利用条件熵(CE)和近似熵(ApEn)对短序列进行分析。采用双向重复测量方差分析评估位置、组和相互作用效应。CE仅显示位置效应，ApEn仅显示组效应。ApEn似乎更适合于评估脆弱综合征复杂性的变化。
