In COPD, patients with abnormally high exertional breathlessness on CPET are unlikely to be identified via standard symptom ...

Second, we performed pulmonary function tests, necessitating participants to have an FEV1/FVC ratio below 70% after inhaling a bronchodilator. Participants fulfilling this condition were classified as ...

FVC also may be expressed as a percentage of the predicted FVC. Your FVC value may be used to calculate your FEV1/FVC ratio. The ratio of FEV1 to FVC compares the amount of air that can be forcefully ...

T-Slope is a measure of airway luminal remodeling and is associated with respiratory morbidity and mortality. COPD diagnosis was based on post bronchodilator forced expiratory volume in 1 ...

To further examine the effects of lung function and inflammation on the relationships with HF, we used the following models. Model 3: Model 2+%FVC, Model 4: Model 2+FEV1/FVC ratio, Model 5: Model ...

The restricted cubic spline analysis revealed a non-linear negative relationship between METS-VF index and FEV1, FVC, and FEV1/FVC ratio, while a linear negative association was found with FEF25-75%.
