[Pulmonary hemodynamics in patients with hypertension during acute drug tests using obsidan and corinfar]

Two-dimensional and Doppler echocardiographies were used to examine 102 hypertensive patients who were found to have pulmonary hypertension, whose manifestation was determined by the degree of arterial hypertension, cardiac contractile insufficiency and diminished left heart pump function. The degree of pulmonary hypertension was related to the hemodynamic type and maximal with hypokinetic circulation when the pump function of the heart was minimal. Obsidan caused a decrease in pulmonary and systemic arterial hypertension, producing higher effects with hypokinetic hemodynamics. Corinfar was demonstrated to attenuate pulmonary hypertension to a greater extent. Its action on systemic arterial hypertension was highest in patients with hyperkinetic circulation. Heterodirectional hemodynamic effects of these drugs make it expedient to study their combined action on the hemodynamic of hypertensive patients.
