Lung cancer and cardiovascular comorbidities dominate COPD mortality until respiratory causes contribute to overall mortality in the advanced stages of the disease. 肺癌和心血管合并症是慢性阻塞性肺病死亡率的主要原因,而呼吸原因导致疾病晚期的总体死亡率 Patients with COPD who have predominant emphysema have ...
According to the Global Initiative for Chronic Obstructive Lung Disease program, the stages of COPD are based on the forced expiratory volume in 1 second (FEV1) of a standard predicted value as follows: Stage I is FEV1 of equal to or more than 80% of the predicted value; stage II is FEV...
Clinical stages of chronic obstructive pulmonary disease(COPD) have been described in the guideline by American Thoracic Society(ATS), European Respiratory Society(ERS), and Japanese Respiratory Society. Recently, the clinical stage in GOLD(Global Initiative Obstructive Lung Disease) was also published ...

The two purposes of this study were to examine the test-retest reliability of three widely used dyspnea instruments and to compare dyspnea scores at different stages of disease. At paired baseline visits, 101 stable patients with COPD were tested; at paired follow-up visits at 3 months, 89 ...
What Are the Four Stages of COPD? The Global Initiative for Chronic Obstructive Lung Disease (GOLD) Program has standardized COPD's nomenclature and treatment recommendations. Their staging system for all patients who have an FEV1/FVC ratio of <70% is as followed: ...
Results Smoking cessation reduced lung function decline at all stages of COPD, and the earlier the intervention, the greater the impact on lung function. Accumulating data from placebo-controlled trials suggested that long-acting bronchodilators can slow the decline in lung function, as well as ...
Chronic obstructive pulmonary disease (COPD) may sound like a single condition, but it includes three kinds of lung disease: Chronic bronchitis Emphysema Chronic obstructive asthma All of them can make you feel breathless. Doctors use stages to describe how severe your COPD is. This system is cal...
COPD is an ongoing lung disease that has no cure and worsens over time. It's estimated that 300 million people around the world live with COPD. There are four stages of the illness, ranging from mild to severe. Doctors grade the stages by how much your airflow is blocked. A simple tes...
