摘要: 目的: 通过心肺运动试验(CPET)进行二尖瓣关闭不全的运动病理生理学特征的相关研究。方法: 自2016年以来签署知情同意后,严格质控下完成规范化CPET极限运动的中重度二尖瓣关闭不全患者26例,取同期正常人11例为对照组。将CPET核心指标按照标准方法分析计算,并与正常人比较,进行组间统计学独立样本t检验。同时将患者是否存在心衰和波浪式呼吸(OB)分别分为两个亚组;其中无心衰11例,心衰15例;非OB 8例,OB18例,并分别对各亚组间比较其异同。结果: 正常人峰值摄氧量(85.60± 9.06)%pred及无氧阈(87.59 ±15.38)%pred等CPET核心指标均为正常范围。二尖瓣关闭不全患者CPET的峰值摄氧量为(48.15 ±12.11)%pred、峰值氧脉搏(66.57±12.20)%pred 、无氧阈(56.75 ±11.50)%pred、摄氧通气效率峰值平台(OUEP)(88.24 ±16.42)%pred、二氧化碳排出通气效率最低值(125.89 ±27.05)%pred和二氧化碳排出通气斜率(128.31 ±31.68)%pred,其中仅摄氧通气效率峰值平台属于正常偏低,其余指标均为显著异常;且与对照组均存在显著差异(P<0.01)。无心力衰竭组与心力衰竭组组间比较均无差异(P>0.05),但所有指标均与对照组有显著差异(P<0.05);非OB组与OB组组间比较均无差异(P>0.05),但均与对照组有显著差异(P<0.05)。结论: 二尖瓣关闭不全病人除摄氧通气有效性正常偏低外,所有心肺运动核心指标均显著异常。且有无心衰和OB均未影响其心肺运动功能状态。

Abstract: Objective: Cardiopulmonary exercise testing (CPET) was used to investigate the exercise pathophysiology of mitral regurgitation. Methods: 26 patients with moderate and severe mitral regurgitation who completed standardized extreme exercise CPET under strict quality control after signing informed consent since 2016, and 11 normal subjects in the same period as the control group. The core indexes of CPET were analyzed and calculated according to the standard method and compared with normal subjects for intergroup statistical independent sample t-test. At the same time, the patients with heart failure and exercise oscillation breathing (OB) were divided into two subgroups: 11 cases without heart failure, 15 cases with heart failure, 8 cases with non-OB and 18 cases with OB, and their similarities and differences were compared between each subgroup. Results: The core indexes of CPET, such as peak oxygen uptake (85.60 ±9.06)%pred and anaerobic threshold (AT, (87.59 ±15.38)%pred) were normal. The peak oxygen uptake of CPET in patients with mitral regurgitation was (48.15 ±12.11)%pred, peak oxygen pulse was (66.57 ±12.20)%pred, AT was (56.75 ±11.50)%pred, oxygen uptake efficiency plateau was (88.24 ±16.42)%pred , lowest value of carbon dioxide ventilatory efficiency was (125.89 ±27.05)%pred and slope of carbon dioxide ventilatory efficiency was (128.31 ±31.68)%pred. Among them, only oxygen uptake efficiency plateau (OUEP) was normal and low, and the other indexes were significantly abnormal. There were significant differences between the patients and the control group (P<0.01). There was no significant difference between the non-OB group and the OB group, but there was significant difference between the non-OB group and the control group (P<0.05). There was no significant difference between the non-heart failure group and the heart failure group, but there was significant difference between the non-heart failure group and the control group. Conclusion: All the core indexes of cardiopulmonary exercise are significantly abnormal in patients with mitral regurgitation who are significantly lower than those in normal subjects except for the low effectiveness of oxygen ventilation. And with or without heart failure and OB did not affect the cardiopulmonary function.
