摘要:

目的 观察通气有效性对慢性阻塞性肺疾病(COPD)患者运动后心脏功能的影响。

方法 2019年1月至2020年12月,广东省人民医院门诊COPD患者190例行症状限制性递增功率踏车运动测试,记录患者一般情况、既往病史和用药史、肺通气功能与心肺运动测试参数,根据踏车运动后第1分钟心率下降是否> 12次,将患者分为正常组和延迟组。

结果 延迟组共89例(46.84%)。与正常组相比,延迟组年龄更高(Z = 2.282, P < 0.05),第一秒用力呼气容积占预测值百分比(Z = 3.626, P < 0.001)、最大功率(t = 5.547, P < 0.001)、剩余呼吸储备(t = 2.122, P < 0.05)下降,通气有效性曲线最低值(VE/VCO2nadir)明显升高(Z = 3.296, P = 0.001)。Logistic回归分析显示,气道阻塞严重程度分级、VE/VCO2nadir、剩余呼吸储备与心率恢复延迟相关;校正性别、年龄、体质量指数和气道阻塞严重程度分级后,VE/VCO2nadir是心率恢复延迟的独立危险因素(OR = 1.203, 95%CI 1.032~1.873, P < 0.01),最佳预测界值为33.15 (AUC = 0.6387, 95%CI 0.5595~0.7178, P = 0.001)。

结论 COPD患者通气有效性障碍增加运动后心率恢复延迟的风险。

Abstract:

Objective To observe the relationship of ventilatory efficiency to cardiac function, especially heart rate recovery after exercise for patients with chronic obstructive pulmonary disease (COPD).

Methods From January, 2019 to December, 2020, 190 patients with COPD were recruited for Cardiopulmonary Exercise Testing. The general condition, medical history and medication history, lung function test and parameters of Cardiopulmonary Exercise Testing were recorded. They were divided into normal group and delay group according to whether the heart rate decline more than twelve beats within a minute after Cardiopulmonary Exercise Testing.

Results There were 89 patients (46.84%) in the delay group. Compared with the normal group, the delay group were older (Z = 2.282, P < 0.05), with less ratio of force exiratory volume in the first second in prediction (FEV1.0%) (Z = 3.626, P < 0.001), maximum power (t = 5.547, P < 0.001), breath reserve (BR) (t = 2.122, P < 0.05) and higher minimum ventilation equivalent of carbon dioxide (VE/VCO2nadir) (Z = 3.296, P = 0.001). Logistic regression showed that the COPD severity, VE/VCO2nadir and BR correlated with heart rate recovery. After adjusting for gender, age, body mass index and COPD severity, VE/VCO2nadir was an independent risk factor for delayed heart rate recovery (OR = 1.203, 95%CI 1.032 to 1.873, P = 0.004), and the best cut-off point was 33.15 (AUC = 0.6387, 95%CI 0.5595 to 0.7178, P = 0.001).

Conclusion The ventilatory inefficiency may increase the risk of abnormal heart rate recovery after exercise in COPD patients.
