[Effect of nitroglycerin on various indicators of hemodynamics in patients with chronic obstructive bronchitis complicated by pulmonary hypertension].

Kinetocardiography and integral rheography of the body were used to examine the effect of nitroglycerin on the hemodynamics in 17 patients with chronic obstructive bronchitis complicated by pulmonary hypertension. The drug exerted a pronounced hypotensive action on the pressure in the pulmonary artery, increased the cardiac output at the expense of the stroke volume, reduced the resistance to the pulmonary blood flow and the peripheral vascular resistance.
