Chronic obstructive pulmonary disease (COPD) presents a major global health burden. While FEV1/FVC is the diagnostic gold standard, its application is limited by patient compliance and procedural complexity. FEV3/FEV6 has been proposed as a simpler alternative for early COPD screening, but its diagnostic and prognostic value remains unclear. This study aims to evaluate the effectiveness of FEV3/FEV6 in diagnosing mild to moderate COPD and predicting patient outcomes.
A total of 200 patients suspected of having mild to moderate COPD underwent FEV3/FEV6 and FEV1/FVC testing from June 2019 to June 2021 and were followed for 3 years. Correlation analysis and ROC curve analysis were conducted.
FEV6 correlated strongly with FVC ( = 0.981) and FEV3/FEV6 with FEV1/FVC ( = 0.928). FEV3/FEV6 showed high diagnostic accuracy (AUC = 0.953; sensitivity 87.92%; specificity 84.77%) and prognostic relevance (AUC = 0.783; sensitivity 80.3%; specificity 66.2%).
FEV3/FEV6 is a reliable tool for early diagnosis and prognosis assessment in mild to moderate COPD.
慢性阻塞性肺疾病(COPD)是一项重大的全球健康负担。虽然FEV1/FVC是诊断的金标准,但其应用受到患者依从性和操作复杂性的限制。FEV3/FEV6已被提议作为早期COPD筛查的一种更简单的替代方法,但其诊断和预后价值仍不明确。本研究旨在评估FEV3/FEV6在诊断轻度至中度COPD及预测患者预后方面的有效性。
2019年6月至2021年6月,共有200例疑似患有轻度至中度COPD的患者接受了FEV3/FEV6和FEV1/FVC检测,并进行了3年的随访。进行了相关性分析和ROC曲线分析。
FEV6与FVC高度相关(r = 0.981),FEV3/FEV6与FEV1/FVC高度相关(r = 0.928)。FEV3/FEV6显示出较高的诊断准确性(AUC = 0.953;灵敏度87.92%;特异度84.77%)和预后相关性(AUC = 0.783;灵敏度80.3%;特异度66.2%)。
FEV3/FEV6是轻度至中度COPD早期诊断和预后评估的可靠工具。
