Aim. Assess the diagnostic significance of markers of heart failure, to identify the features of clinical symptoms and structural and functional remodeling of the left and right heart in patients with chronic heart failure (CHF) in combination with atrial fibrillation (AF) and chronic obstructive pulmonary disease (COPD). Materials and methods. groups of patients were formed: group 1 – patients with COPD without cardiovascular diseases (n=28), group 2 – patients with CHF and COPD without AF (n=30), group 3 – patients with CHF and AF without COPD (n=33), group 4 (main) – patients with CHF, AF and COPD (n=29). Patients were evaluated for clinical symptoms, 6-minute walk test, echocardiographic study, determined the concentration of natriuretic peptides (NUP): N-terminal fragment of the precursor of cerebral NUP (NT-proBNP) and mid-regional pro-atrial NUP (MR-proANP). Results. In patients with CHF on the background of AF and COPD, a higher score of the severity of clinical symptoms was established in comparison with the 3rd group (p<0,001). The features of heart remodeling in patients of the main group were revealed in comparison with patients with CHF and AF without COPD: lower volume indices of the left (p=0,001) and right (p=0,004) atria and values of the indexed index of the end-diastolic area of the right ventricle (RV) (p=0,007), lower contractility of the RV, the presence of RV hypertrophy. The effect of AF on the structural and functional parameters of the heart in patients with CHF, COPD and AF can be judged by comparison with patients with CHF and COPD without AF: higher values of the size of the RV (p=0,012), indexed index of the end-systolic area of the RV (p<0,001), lower systolic function of the RV on the background of higher pressure in the RV cavity (p=0,001). Defined the highest level of NT-proBNP in patients with CHF, AF and COPD in comparison with its level in patients of the 2nd group (p<0,001) and in patients 3rd groups (p=0,010). Higher levels of MR-proANP were found in patients with CHF and AF without COPD (p<0,001). Conclusion. In patients with CHF, AF and COPD, more pronounced clinical symptoms are caused by chronic bronchial obstruction. Pathogenetic features of left and right heart remodeling in patients with CHF on the background of AF and COPD were revealed. For the early detection of HF in patients with AF the greatest diagnostic importance is the determination of the level of MR-proANP, however, in patients with combined AF and COPD the most informative is the determination of the concentration of NT-proBNP.
