GOLD 0 - DLCO 1: A Look Beyond the Obstruction. Is Spirometry Enough for COPD (Chronic Obstructive Pulmonary Disease) Screening?
GOLD 0 - DLCO 1: A Look Beyond the Obstruction. Is Spirometry Enough for COPD Screening?
This is a multicenter observational prospective study in smokers or ex-smokers with cumulative exposure ≥ 10 a / p (years / pack) with respiratory symptoms and presenting a normal spirometry.
The patients who sign the corresponding informed consent, will undergo a DLCO and will be divided into two groups according to the result:
- Group I. Patients with DLCO <80%.
- Group II Patients with DLCO≥80%.
Both groups will be followed for 5 years.
