Abstract
In 9 patients with chronic renal failure, cardiac function was analyzed immediately before and after hemodialysis using the cardiac catheterisation. Long-standing hypertension was seen in all patients but one case.
LA, PA, RV and RA pressure in the predialysis examination was high and each pressure decreased by hemodialysis. In the patients with the pressure of slightly above the normal range, the intracardiac pressure was normalized but no significant improvement was seen in the case who had high intracardiac pressure before hemodialysis.
The ventricular stroke work index was high in both left and right ventricle, however the latter was significantly. The index was normalized by hemodialysis slightly.
After hemdialysis cardiac index decreased in 4 cases, increased in 3 cases and no change was observed in one case. High PSR was decreased however TSR was unchanged by hemodialysis.
Most of these changes were explained by the reduction of circulatory blood volume and the improvement of cardiac reserve although several factors were involved in the pathogenesis of circulatory disturbance.
As the results, it is important to control the hypertension in uremic patients for the prevention of circulatory congestion.
