[Effect of short-term antiorthostatic hypokinesia on the central and intracardiac hemodynamics and metabolism in a healthy human being].
The right parts of the heart and the radial artery were catheterized in healthy male volunteers before and 5 days after strict bed rest in antiorthostatic position of the body (-4.5 degrees) After immobilization most values of central circulation showed no essential changes; the only exception were indices characterizing the inotropic myocardial condition. A shift in the direction of acidosis of a mixed character was noted in mixed venous blood, the beta-lipoprotein content increased. A decrease in the arteriovenous difference in oxygen was encountered in blood draining from the heart (from the coronary sinus).
