研究目的: |
1.同时探索相较稳定期COPD患者,PRISm阶段人群经体外膈肌起搏治疗后肺功能、膈肌形态与功能、全身炎症的改善效果。 2.EDP是否可以改善PRISm人群受损的肺功能。 3.探索使用体外膈肌起搏治疗前后保留比值受损肺功能(PRISm)状态到慢性阻塞性肺疾病(COPD)发展的互相关联性。 |

Objectives of Study: |
1. To simultaneously explore the improvements in lung function, diaphragm morphology and function, and systemic inflammation in individuals with PRISm (preserved ratio impaired spirometry) after external diaphragm pacing (EDP) therapy, compared with patients with stable COPD. 2. Whether EDP can improve the impaired lung function in the PRISm population. 3.To explore the interrelationship between the preserved ratio impaired spirometry (PRISm) status and the development of chronic obstructive pulmonary disease (COPD) before and after treatment with external diaphragm pacing (EDP). |

纳入标准: |
1. 健康受试者: (1) 年龄>=18岁; (2) 无慢性肺部疾病史且近3个月无呼吸道感染症状; (3) 肺功能检查结果正常,无慢性呼吸道疾病史。 2. PRISm受试者: (1) 年龄>=18岁; (2) 排除哮喘、支气管扩张、肺纤维化等慢性肺部疾病史且近3个月无呼吸道感染症状; (3) 肺功能检查满足肺活量比值保留(支气管扩张后 FEV1/FVC>=0.7)但肺活量受损(支气管扩张后 FEV1<参考值的80%)的特征。同时结合临床症状、影像学检查等综合判断,排除其他严重肺部疾病。 3. 稳定期COPD受试者: (1) 年龄>=18岁; (2) 诊断基于病史、临床症状和肺功能测试,符合2024年GOLD慢阻肺全球倡议诊断标准; (3) 患者咳嗽、咳痰、气短等症状稳定或症状轻微; (4) 近3个月慢阻肺药物治疗方案不变。并进一步根据 FEV1 占预计值的百分比分为轻度(FEV1>=80% 预计值)、中度(50%<=FEV1<80% 预计值)、重度(30%<=FEV1<50% 预计值)、极重度(FEV1<30% 预计值)。 |
