The mechanisms of intracardiac adaptation in dialysis patients: data of radioisotopic ventriculography
Abstract
Radioisotope ventriculography was performed in 36 stable dialysis patients in the beginning and at the end of haemodialysis sessions for studying remodeling of cardiovascular system and the mechanisms of intradialysis hypotension. It has been shown that adequate ventricle refilling plays a critical role in the maintenance of cardiac outputduring haemodialysis with ultrafiltration. In the left ventricle the active refilling phase was more significant than in the right one. Interestingly, the decrease of the right ventricle output was accompanied by augmentation of the left ventricle output ( r =−0,91). It can be a mechanisms providing blood return to the right heart. Based on data obtained a theoretical model of adaptation of cardiovascular system in haemodialysis patients was suggested.
