OBJECTIVE
The aim of this study was to elucidate the relationship between atrial fibrillation (AF) and chronic obstructive pulmonary disease (COPD) classification based on clinical severity determined in current guidelines. AF is the most common chronic arrhythmia that requires treatment. COPD is one of the risk factors for AF, but this relationship was only explored through respiratory function test results.

METHODS
Patients who received inpatient treatment for COPD between November 2019 and January 2017 were screened. Patients with coronary artery disease, heart failure, valvular heart disease, diabetes, chronic kidney disease, hypertension, thyroid dysfunction, and sleep apnea syndrome were excluded. According to the 2019 Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, patients with COPD were divided into groups A, B, C, and D, and the relationship between AF and these groups was investigated.

RESULTS
There was no difference between the two groups (depending on the presence of AF) in terms of sex and body mass index. There was a significant difference between the two groups in terms of age, left ventricular ejection fraction (LVEF), left atrium, right atrium, right ventricle, and systolic pulmonary artery pressure. When patients with COPD were classified according to clinical and symptomatic severity, the frequency of AF increased as the clinical severity increased.

CONCLUSION
Regardless of the forced expiratory volume – first second (FEV1) value in the respiratory test, the incidence of AF is higher in patients with COPD with a clinically more severe picture.
