for grading the severity of chronic obstructive pulmonary disease (COPD) based on the FEV1/FVC ratio, termed STaging of Airflow obstruction by Ratio (STAR), which demonstrated comparable predictive performance for mortality compared to the conventional FEV1 present predicted (pp...
Patients were classified according to COPD severity (1) in GOLD 2016 "ABCD" categories based on symptoms (Medical Research Council dyspnea grade, COPD Assessment Test, breathlessness), percent predicted FEV1, and exacerbation history and (2) as mild, moderate, severe, or very severe based on ...
Pulmonary function assessments, specifically the measurement of the ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC), serve as a primary diagnostic and risk assessment tool for COPD [4]. However, early COPD patients are easy to be ignored because of asymptom...
The diagnosis and severity of COPD was based on clinical history and spirometry criteria according to the GOLD guidelines. COPD was regarded as the ratio of post-bronchodilator FEV1 to FVC < 0.7. In this study, the severity of COPD was divided into two stages, namely, mild-moderate airflow ...
When comparing sputum MPO and HNL/NGAL levels in terms of their relationship with pulmonary function parameters, sputum MPO levels showed significant negative correlations with FEV1 (r = -0.235, p = 0.033), FEF25-75 (r= -0.228, p = 0.038). As shown in Table 2, sputum HNL/NGAL...
Results: We enrolled 1084 patients of whom 1072 had acceptable spirometry. 689 (64%) had airflow obstruction (FEV1/FVC≤0.70) while 383 (36%) failed to meet spirometric criteria for COPD despite receiving maintenance therapy and having comparable symptoms and co- morbid illness. Among those ...
We measured the degree of dyspnea using the mMRC score, which was significantly higher in bronchiectasis with obstructive ventilatory disorder. mMRC is a subjective measure of dyspnea in COPD, which is known to be associated with the decrease in FEV116. Similarly, in our study, the degree of ...
Sputum NET complexes were associated with the severity of COPD evaluated by using the composite Global Initiative for Obstructive Lung Disease scale (P < .0001). This relationship was due to modest correlations between NET complexes and FEV1, symptoms evaluated by using the COPD assessment test, ...
The present study investigated the relationship between certain periodontal variables and severity of disease in COPD patients. Methods. The present cross-sectional study included 50 patients suffering from COPD. Lung function examination, forced expiratory volume in one second (FEV1), forced vital ...
#Abnormal AST: The number of subjects whose AST was greater than 40 IU/L. Abbreviations: COPD, chronic obstructive pulmonary disease; GOLD, Global Initiative for Obstructive Lung Disease; BMI, body mass index; FEV1, forced expiratory volume in a second; RV, residual capacity; TLC, total lung...
