| description | Studies of endothelial dysfunction in patients with respiratory diseases have become relevant in recent years. Perhaps endothelial dysfunction and high arterial stiffness bind bronchopulmonary and cardiovascular diseases.Aim. To reveal features of disturbances of arterial wall vasoregulatory function in patients with chronic obstructive pulmonary disease (COPD) in the presence and absence of arterial hypertension (HT).Material and methods. The study included 50 patients with COPD with normal blood pressure (BP) and 85 patients with COPD and HT. Control group was presented by 20 practically healthy men comparable in age with COPD patients. Tests with reactive hyperemia (endothelium-dependent dilation) and nitroglycerin (endothelium-independent dilation) were performed in order to evaluate endothelium function. The number of desquamated endotheliocytes in the blood was determined.Results. In patients with COPD and HT in comparison with COPD patients without HT and healthy individuals more pronounced damages of the vascular wall, endothelium vasoregulatory function disturbances and a tendency to the reduction in endothelium-dependent vasodilation were determined both during COPD exacerbation and remission. These differences were most pronounced during the COPD exacerbation. In patients with COPD and HT in comparison with COPD patients without HT the damage of the vascular wall was more pronounced during the remission and endothelium-dependent dilatation disorder – during the exacerbation. The revealed disorders in patients with COPD and HT were associated with smoking status (r=0.61, p<0.01), severity of bronchial obstruction (r=-0.49, p<0.05), and hypoxemia (r=-0.76, p<0.01). We noted relationships between the parameters of 24-hour BP monitoring and remodeling of the brachial artery (r=0.34, p<0.05), endothelium lesion (r=0.25, p<0.05), and impairment of its vasoregulating function (r=-0.58, p<0.05). At that, the following parameters were important: the average systolic and diastolic BP levels, the BP load and variability indices, the time and rate of morning surge in systolic BP, and the circadian rhythm of BP.Conclusion. The obtained data show the aggravation of the severity of the vascular wall damages and the reduction in the endothelium vasoregulating activity in patients with COPD after development systemic HT. This effect is more evident during the exacerbation of bronchopulmonary disease. |
