This multicentre observational trial used data from the COPDGene Study to investigate whether pulmonary vascular disease is associated with acute exacerbations of chronic obstructive pulmonary disease (COPD).
Although severe pulmonary hypertension is a well recognised late complication of the disease, the study questioned whether earlier radiological changes could be used as a predictor for exacerbations. CT was used to provide a measure of pulmonary artery (PA) enlargement, using the ratio of PA diameter as compared with the diameter of the aorta (A).
The study population included 3464 patients with a diagnosis of Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage II–IV COPD. These patients were longitudinally followed up for a median duration of 2.1years, as was an...
Collecting samples of exhaled breath from people at a high risk of lung cancer could be a cheap and non-invasive method of diagnosing the disease, according to new research. The findings were presented on 9 September 2013 at the European Respiratory Society (ERS) Annual Congress in Barcelona.
Current tests for lung cancer include blood and urine tests, followed by CT scans and chest radiographs. This new method could see people at a high risk of lung cancer receiving an initial breath test to quickly assess their symptoms... ()
