RESPIRATORY AND HEMODYNAMIC DISTURBANCES IN SUBJECTS EXPOSED TO LOW-DOSE RADIATION AFTER THE CHERNOBYL ACCIDENT

After examination of cardiorespiratory function in 10 males exposed to Chernobyl accident unfavorable factors at the age of 31-45 years suff ering from chronic obstructive bronchitis (7 cases) and mixed bronchia l asthma (3 cases) it was established that the patients had ventilatio n disorder; of mixed genesis (moderate obstructive and respiratory aff ections), frequently occurring decreased specific diffusion (DLCO/Va) in normal total diffusion capacity of the lungs, inefficient gas excha nge, mildly declined left ventricular pump capacity and contractility. In the above patients a relationship was found between parameters of central hemodynamics assessed at echo-CG and severity of ventilation i mpairment and respiratory insufficiency.
