Abstract
Aim. To study β-adrenoreactivity of the cell membrane in patients with different variants of heart failure in association with chronic obstructive pulmonary disease.Methods. 120 heart failure patients including 68 of them who suffer from concominant chronic obstructive pulmonary disease were evaluated. Assessment of clinical features of heart failure, patients’ quality of life and study of β-adrenoreactivity were performed.Results. Adrenoreactivity of an organism in heart failure and concominant chronic obstructive pulmonary disease was 2 times higher and was 55.4±18.8 U and in heart failure only it was 29.4±8.5 U. Intensification of β-adrenoreactivity was found to be proportional to worsening of clinical features of chronic heart failure in all patients that was more prominent in patients with pulmonary disease. Responders with heart failure in association with chronic obstructive pulmonary disease had higher values of β-adrenoreactivity of cell membranes more frequently.Conclusion. The results of our investigation confirm increased activity of sympathetic system in heart failure and concominant chronic obstructive pulmonary disease that worsens clinical manifestations of heart failure.
