摘要

Cardiovascular disease is up to 10 times more likely among childhood cancer survivors compared to siblings. Low cardiorespiratory fitness is a modifiable risk-factor for cardiovascular diseases. Yet, cardiorespiratory fitness is not routinely screened in pediatric oncology, and healthy VO2max cut-points are unavailable. We aimed to predict cardiorespiratory fitness by developing a simple algorithm and establish cut-points identifying survivors' cardiovascular fitness health-risk zones. We recruited 262 childhood cancer survivors (8-18 years old, ≥1-year posttreatment). Participants completed gold-standard cardiorespiratory fitness assessment (Cardiopulmonary Exercise Test [CPET; VO2max ]) and 6-minute walk test (6MWT). Associations with VO2max were included in a linear regression algorithm to predict VO2max , which was then cross-validated. We used Bland-Altman's limits of agreement and Receiver Operating Characteristic curves using FITNESSGRAM's "Healthy Fitness Zones" to identify cut-points for adequate cardiorespiratory fitness. A total of 199 participants (aged 13.7 ± 2.7 years, 8.5 ± 3.5 years posttreatment) were included. We found a strong positive correlation between VO2max and 6MWT distance (r = 0.61, r2 = 0.37, p

儿童癌症幸存者患心血管疾病的可能性是兄弟姐妹的 10 倍。低心肺适应性是心血管疾病的一个可变风险因素。然而,心肺适应性没有在儿科肿瘤学中常规筛查,健康的最大摄氧量切点也不可用。我们的目的是通过开发一个简单的算法来预测心肺适应性,并建立识别幸存者心血管适应性健康危险区域的切割点。我们招募了 262 名儿童癌症幸存者 (8-18 岁,治疗后 ≥ 1 年)。参与者完成了黄金标准心肺健康评估 (心肺运动测试 [CPET; VO2max]) 和 6 分钟步行测试 (6MWT)。与 VO2max 的关联包含在预测 VO2max 的线性回归算法中,然后交叉验证。我们使用 Bland-Altman 的一致性极限和使用 FITNESSGRAM 的 “健康健身区” 的受试者操作特征曲线来确定适当心肺健身的切割点。共纳入 199 名参与者 (年龄 13.7 ± 8.5 岁,治疗后 ± 岁)。我们发现最大摄氧量和 6MWT 距离之间有很强的正相关 (r = 0.61,r2 = 0.37,p

6-minute walk test

心血管 康复 临床研究术语
概述  :  

六分钟步行试验(6MWT)是指测量病人在六分钟内,在没有障碍的硬地上以尽可能快的速度步行最远能达到的距离。国际上应用6分钟步行试验作为对中、重度疾病患者全身功能状态的综合评价之一。背景对于功能代偿能力的客观评价有几种不同的形式。最流行的临床运动试验按复杂程度由低到高依次为爬楼、6MWT、往返步行试验、运动性哮喘检测、心脏负荷试验(如Bruce方案)和心肺运动试验。在20世纪60年代早期,Balke提出了一个简单的评价功能代偿能力的方法,即测量在规定的时间内的步行距离。然后发展出了测定健康人体
