Fenotypové hodnocení nemocných s těžkou formou chronické obstrukční plicní nemoci pomocí HRCT hrudníku (Prospektivní sledování nemocných v rámci Národní výzkumné databáze CHOPN)

Phenotypic assessment of patients with severe chronic obstructive pulmonary disease with using HRCT of the lung Aim Chronic obstructive pulmonary disease (COPD) is very important societal and economic problem worldwide. The main risk factor form COPD is tabacco smoke. CODP patients are very heterogenic group with different clinical symptoms.

Materials and methos Patients from Czech multicentre research database of severe COPD which is registered on www.clinicaltrials.gov with number NCT01923051were analysed. The analysis of CT scans with clinical symptoms and lung functional tests was performed. Results From May 2013 were 784 patients included to the database.
