Abstract

Abstract:

Background

Cardiopulmonary exercise testing (CPET) is essential for assessing the maximal exercise capacity of patients with chronic obstructive pulmonary disease (COPD) and for developing rehabilitation prescriptions. Body composition has been shown to be associated with CPET results, which is complex, time-consuming, contraindicated, and risky, and cannot be performed in some COPD patients, whereas body composition analysis is simple and fast.

Objective

This paper focuses on the correlation between body composition and CPET in patients with COPD, and provides a basis for predicting maximal exercise capacity, formulating rehabilitation prescriptions, and rational nutritional support for patients with COPD who are unable to complete cardiopulmonary exercise testing.

Methods

Stable COPD patients were enrolled in the outpatient respiratory clinic of China-Japan Friendship Hospital between July 2021 and March 2022, and were sequentially subjected to body composition measurements and CPET with continuous incremental loading, and the test results were analyzed to assess the relationship between body composition and CPET results, and to analyze the value of the body composition indexes in predicting the results of CPET.

Results

Seventy-seven eligible patients with stable COPD completed body composition measurement and exercise cardiopulmonary exercise testing. Correlation analysis showed that body fat percentage (BFP) was negatively correlated with peak metabolic equivalents (peakMETs) (P<0.01) ; skeletal muscle mass index (SMI) was positively correlated with peak oxygen uptake (peakVO₂), peak load, peak ventilation volume (peakVE), maximum heart rate (peakHR), peak oxygen pulse (peakO₂pulse), and oxygen uptake efficiency slope (OUES) at the highest exercise state were positively correlated (P<0.01) ; and the fat free mass index (FFMI) was positively correlated with peakVO₂, peakLoad, peakVE, peakO₂pulse, and OUES (P<0.01). The results of multivariable linear regression analysis showed that SMI and FFMI were independently and positively correlated with peakLoad, peakVE, peakO₂pulse, and OUES in patients with COPD (P<0.05). BFP was independently and negatively correlated with peakMETs in patients with COPD (P<0.05). SMI had better predictive ability than FFMI for the results of the CPET trial in COPD patients peakLoad, peakVE, peakO₂pulse, and OUES.

Conclusion

Muscle content is positively correlated with the exercise capacity of COPD patients, and the results of body composition measurement can be used as an important criterion for predicting the exercise capacity of COPD patients, guiding the rehabilitation exercise and rational nutritional support therapy.

摘要：

背景

心肺运动试验（CPET）对于评估慢性阻塞性肺疾病（COPD）患者最大运动能力以及制订康复处方有着至关重要的作用。有研究表明，身体成分与CPET结果相关。CPET操作复杂、耗时长、禁忌证较多且风险大，一些COPD患者无法完成，而身体成分分析操作简单快捷。

目的

探讨COPD患者的身体成分与CPET的相关性，为不能完成CPET的COPD患者预测最大运动能力、制订康复处方、合理营养支持提供依据。

方法

回顾性选取2021年7月—2022年3月于中日友好医院进行身体成分检测和CPET检测的稳定期COPD患者77例，依次进行身体成分测定和负荷连续递增的CPET，评估身体成分和CPET结果的关系。

结果

77例符合要求的稳定期COPD患者均完成了身体成分测定和CPET。相关性分析结果显示，体脂率（BFP）与最高运动状态时代谢当量（peakMETs）呈负相关（P<0.01）；骨骼肌质量指数（SMI）与最高运动状态时摄氧量（peakVO₂）、最高运动状态时运动负荷（peakLoad）、最大分钟通气量（peakVE）、最高运动状态时心率（peakHR）、最高运动状态时氧脉搏（peakO₂pulse）、摄氧效率斜率（OUES）呈正相关（P<0.01）；去脂体质量指数（FFMI）与peakVO₂、peakLoad、peakVE、peakO₂pulse、OUES呈正相关（P<0.01）。多元线性回归分析结果显示，SMI、FFMI与COPD患者peakLoad、peakVE、peakO₂pulse、OUES呈独立正相关（P<0.05）；BFP与COPD患者peakMETs呈独立负相关（P<0.05）。其中在因变量为peakLoad、peakVE、peakO₂pulse、OUES的多元线性回归分析中，SMI的β值高于FFMI。

结论

肌肉含量与COPD患者的运动能力呈正相关，身体成分测定结果可以作为COPD患者运动能力预测、指导康复运动、合理营养支持治疗的重要标准。
