Checking for airflow limitation in smokers attending cardiology clinics

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study screens cardiology outpatients aged 40 and above with a smoking history of at least 10 pack‑years using spirometry and the COPD Assessment Test (CAAT). Patients are recruited at participating cardiology clinics in Ankara and Istanbul, provide written consent, complete the questionnaire, and undergo spirometry unless excluded for asthma or recent bronchodilator use. The primary goal is to estimate the prevalence of undiagnosed airflow limitation among smokers seen in cardiovascular outpatient settings. Results will be compared with regional COPD prevalence data to determine whether cardiology clinics are high‑yield sites for case-finding.
