Difficulty in activities of daily living (ADL) is common in patients with cardiovascular disease (CVD) and is associated with mortality.
The relationship between gait speed/6-minute walking distance (6MWD) and difficulties in ADL in patients with CVD was explored.
The study population consisted of 447 patients with CVD for whom data on gait speed, 6MWD, and difficulty in ADL during outpatient rehabilitation were available. Relationships of gait speed/6MWD and difficulty in ADL were examined using propensity-adjusted logistic regression analysis.
Both gait speed and 6MWD were significantly related to difficulty in ADL, and the areas under the curves were large. The cutoff values ranged from 0.93 to 1.30 m/s for gait speed and 370 to 500 m for 6MWD, from basic ADL to vigorous activities.
Both gait speed and 6MWD were used for the estimation of difficulty in ADL in patients with CVD. Gait speed can be measured easily and therefore could be incorporated in busy clinical practice to identify patients at risk for functional decline.
日常生活活动（ADL）困难在心血管疾病（CVD）患者中很常见，且与死亡率相关。
探讨CVD患者的步态速度/6分钟步行距离（6MWD）与ADL困难之间的关系。
研究人群包括447例CVD患者，他们在门诊康复期间有步态速度、6MWD和ADL困难的数据。使用倾向调整逻辑回归分析检查步态速度/6MWD与ADL困难之间的关系。
步态速度和6MWD均与ADL困难显著相关，曲线下面积较大。从基本ADL到剧烈活动，步态速度的截断值范围为0.93至1.30米/秒，6MWD的截断值范围为370至500米。
步态速度和6MWD均可用于评估CVD患者的ADL困难。步态速度测量简便，因此可纳入繁忙的临床实践中，以识别有功能下降风险的患者。
