摘要: 目的: 探讨心衰患者(CHF)波浪呼吸的周期长度、振幅与运动能力的关系。方法: 237例心力衰竭患者进行症状限制性极限心肺运动试验(CPET)。将CPET每次呼吸的原始数据每秒切割,再进行单位时间的平均计算、分析。波浪式呼吸(OB)定义为CPET期间连续3次及其以上的呼吸波动,其中分钟通气量(VE)波动幅度超过同期均值的25%。存在OB的CHF患者(OB+)根据其峰值摄氧量(Peak VO2)分为3个亚组。第1亚组(轻度CHF)Peak VO2≥16 ml/(min·kg),第2亚组(中度CHF)Peak VO2为12~16 ml/(min·kg),第3亚组(重度CHF)Peak VO2≤12 ml/(min·kg)。结果: 237例CHF患者中,78例OB+患者(32.6%)出现波浪呼吸。在OB+的CHF患者中,OB周期时间长度与Peak VO2r=-0.82)、Peak VO2%pred(r=-0.65)、AT(r=-0.78)呈负相关,与Lowest VE/VCO2呈正相关(r=0.61)。结论: 心衰患者波浪呼吸的平均周期时间长度与整体运动能力呈负相关。

Abstract: Objective: To find out the relationship between the duration and amplitude of oscillatory breathing (OB) and their exercise capacity in patients with chronic heart failure (CHF) we did this study. Methods: Two hundred and thirty-seven CHF patients performed a maximum incremental upright cycle ergometry cardiopulmonary exercise testing (CPET). Respiratory gas exchange was measured on a breath-by-breath basis throughout the test. OB was defined as 3 or more continuous cycle fluctuations of ventilation during CPET, and the amplitude of VE oscillations exceed 25% of concurrent mean value. The CHF patients with OB (OB+) were divided into 3 sub-groups according to their Peak VO2. Group1 (mild OB+) Peak VO2 of ≥16 ml/min/kg, group 2 (moderate OB+) Peak VO2 is between 12~16 ml/min/kg, group 3 (severe OB+) Peak VO2 ≤ 12 ml/(min·kg). Results: There were 78(32.6%) patients detected as OB+ in 237 CHF patients. Among OB+ patients, OB duration in s related negatively to Peak VO2 in mL/min/kg (r=-0.82), Peak VO2 in %pred (r=-0.65), VO2 at AT (r=-0.78), and related positively to VE/VCO2 at AT (r=0.61). Conclusion: OB duration is related negatively to exercise capacity of CHF patients.
