The article deals with changes in arterial rigidity in patients with bronchial asthma, depending on the presence of concomitant hypertension. The aim was to study the arterial rigidity parameters in patients with bronchial asthma depending on the presence of arterial hypertension on the standard antiinflammatory therapy for early diagnosis of complications of the cardiovascular system. A significant increase of arterial rigidity was shown, manifested by an increase in the pulse wave velocity in the aorta (AoPWV) and augmentation index (Alx) in patients with bronchial asthma of moderate and severe course in comparison with the control. In the study of the main indicators of arterial rigidity, depending on the presence or absence of hypertension, it was shown that in the group of patients with hypertension, changes in AoPWV and IA were more significant than in the group of patients with normal blood pressure. Increasing of BMI contributes to the development of arterial rigidity in patients with bronchial asthma. The formation of arterial rigidity is associated with clinical and functional parameters and hypoxemia
