[Possibilities for the strophanthin pharmacological correction of cardio- and hemodynamic disorders in dogs in the early stage of experimental lung-heart failure].

Experiments on intact dogs and animals with an early stage of experimental cardiopulmonary insufficiency due to chronic pneumonia were made to study the action of strophanthine on the hemodynamics of the left and right ventricles and pressure in the pulmonary artery. Administration of the glycoside to animals with cardiopulmonary insufficiency increased the contractility of the right ventricle and the intensity of diastolic relaxation of both ventricles. Strophanthine was revealed to exert the prevailing effect on the cardiodynamics of the right ventricle both in intact dogs and in animals with experimentally induced pathology. Strophanthine increased pressure in the pulmonary artery, promoting the overload of the right ventricle to a less degree than convallotoxin.
