[Evaluation of pulmonary hypertension by dopplerography in patients with nonspecific pulmonary diseases].

Doppler echocardiography was used to quantify pulmonary hypertension and phase pattern of right heart systole in 140 patients with nonspecific pulmonary diseases to study hemodynamic characteristics of pulmonary circulation and right heart as well as external respiration. There appeared a relationship between the severity of pulmonary hypertension, bronchial obstruction and arterial hypoxemia. It seems that in nonspecific pulmonary diseases hemodynamic changes arise prior to functional disorders of external respiration.

[The correction of the hemodynamic disorders in patients with IHD complicated by intraventricular blocks by using beta-adrenergic agents].

Basing on ECG findings, the authors compare hemodynamic effects of a single dose of isadrin, obsidan and spesicor in patients with coronary heart disease complicated by bundle-branch block. Isadrin improves left ventricular contractility, reduces pulmonary hypertension and right heart overload. Obsidan and spesicor aggravate the existing hemodynamic disorders in the above patients.
