ABSTRACT
BACKGROUND AND OBJECTIVE:
COPD is one of the leading causes of morbidity and mortality worldwide, and its prevalence continues to increase. Although spirometry is indispensable for the diagnosis of COPD, other simple and reliable tools are necessary for screening of COPD because spirometry is not widely available. This study investigated the usefulness of a combination of an electronic FEV1/FEV6 meter (PiKo-6) with a COPD questionnaire as a screening method in patients with cardiovascular diseases.METHODS:
The PiKo-6 and the COPD questionnaire of the International Primary Care Airways Group were used to screen patients attending a cardiovascular outpatient clinic. Patients with FEV1/FEV6 < 70% were defined as having airflow limitation. Patients diagnosed with airflow limitation underwent spirometry. Using data from the PiKo-6 and the COPD questionnaire, patients were assigned to a COPD group or a non-COPD group. The relationship between PiKo-6 measurements and spirometry was also evaluated.RESULTS:
Among 753 patients, 82 (10.9%) showed airflow limitation when assessed with the PiKo-6. Of these patients, 79 (10.5%) were assigned to the COPD group. FEV1, FEV6 and FEV1/FEV6, as measured with the PiKo-6, correlated significantly with FEV1, FVC and FEV1/FVC, respectively, as measured by spirometry (r = 0.865, 0.751 and 0.57). Among the cardiovascular comorbidities, heart failure and ischaemic heart disease showed slightly stronger associations with airflow limitation (13.8% and 12.5%, respectively).CONCLUSIONS:
Combination of the PiKo-6 with a COPD questionnaire may be a useful and feasible method of identifying undiagnosed COPD patients attending a cardiovascular outpatient clinic.
