[Blood rheological properties and their interrelation with pulmonary hypertension in patients with chronic dust bronchitis].

Nineteen patients with chronic obstructive disease of the lungs and 15 patients with chronic non-obstructive bronchitis of the dust etiology were examined for the purpose of investigating the rheological blood properties and of their interrelation with pulmonary hypertension. The hemorheological properties were evaluated by spontaneous aggregation of erythrocytes and thrombocytes. The control group comprised 8 healthy subjects. The results denoted that the rheological blood properties are to a great extent impaired in patients with dust bronchitis. The rheological blood properties worsened as hypertension of the small blood-circulation circle was increasing; it preceded the development of pulmonary hypertension in patients with chronic obstructive disease of the lungs. The aggregation changes appear to be primarily related with the functional state of thrombocytes in patients with chronic non-obstructive bronchitis; a concurrently higher aggregation of thrombocytes and erythrocytes was observed in patients with chronic obstructive disease of the lungs. The obtained data can be useful for designing a medicamental correction scheme of rheological impairments as a trend within the treatment of affected hemodynamics in the small blood-circulation circle in patients with duct bronchitis.
