Background

Cardiopulmonary exercise testing (CPET) is a method used to evaluate functional impairment of patients with various diseases.

Objective

The objective was to use CPET to estimate the usability of anthropometric index (AI) in patients with pectus excavatum (PE) as a marker of functional impairment caused by chest deformity.

Methods

The study included 32 paediatric patients (28 males) with PE. Patients underwent CPET using a breath-by-breath exhaled gas analysis method and continuous monitoring of cardiac parameters.

Results

In both groups, two (overall four) patients met criteria for cardiogenic limitation (low VO2 and low O2Pulse). Mean VO2/WR was below two standard deviations (2SD) in patients with less severe PE; other observed parameters were within normal limits (Z-score ± 2 SD). The AI had no observed correlation with peak ventilation, VO2peak and peak workload.

Conclusion

The obtained CPET data do not correlate well with the severity of chest deformity expressed with AI. There were similar physical activity limitations in both examined groups of patients and they did not depend on the severity of the deformity.

漏斗胸患儿体格指数与心肺运动试验的相关性

背景

心肺运动试验(CPET)是一种用于评估患有各种疾病的患者功能障碍的方法。

客观的

目的是使用 CPET 评估漏斗胸 (PE) 患者的人体测量指数 (AI) 作为胸部畸形引起的功能障碍标志物的可用性。

方法

该研究包括 32 名 PE 儿科患者(28 名男性)。患者使用逐次呼吸呼出气体分析方法和连续监测心脏参数进行 CPET。

结果

在两组中,两名(总共四名)患者符合心源性限制标准(低 VO 2和低 O 2脉搏)。在不太严重的 PE 患者中,平均 VO 2 /WR 低于两个标准差 (2SD);其他观察到的参数在正常范围内(Z 分数 ± 2 SD)。没有观察到 AI 与峰值通气、VO 2峰值和峰值工作量的相关性。

结论

获得的 CPET 数据与用 AI 表达的胸部畸形严重程度相关性较差。两组患者的身体活动限制相似,并且不依赖于畸形的严重程度。
