Anxiety and depression in patients with occupational chronic obstructive pulmonary disease comorbid with biventricular heart failure

Abstract

Occupational chronic obstructive pulmonary disease (COPD) patients with (n=44) or without (n=52) biventricular heart failure (HF) were investigated. Comparison groups were COPD in tobacco smokers with (n=38) or without (n=65) HF. Comorbid pathology was characterized by the highest levels of anxiety and depression (HADS-A score was 7.4+0.86, HADS-D score was 7.9+0.75) associated with serum S100В.
