Hemodynamic changes after hemodialysis were analyzed in 18 patients who were treated for chronic renal failure. In each case, (males: 12; females: 6; Age: 25-58 (av. 38.9) ) cardiac catheterization was performed before and after hemodialysis. The following results were obtained: 1) Higher levels of left atrial (LA), pulmonary arterial (PA), right ventricular (RV) and right atrial (RA) pressure were noted in many patients who had hypertension before hemodialysis (especially in cases of Grades III and IV) . It was suggested that the hypertensive state before hemodialysis might easily give rise to right-side heart failure in such cases. Although ventricular stroke work index and total pulmonary resistance increased, total systemic peripheral resistance was within a normal range in many of these cases. 2) RA, RV and PA pressures decreased after hemodialysis. In patients with mild hypertension (Grades I and H), pressures were normalized after inital hemodialysis. Most of these changes can be explained by the reduction of the circulatory blood volume and the improvement of cardiac function. 3) The cases in Grades III and IV showed higher intracardiac pressures on predialysis study, and no significant improvement was obtained after initial hemodialysis. Therefore, frequent hemodialysis were required in these cases. 4) As a result, it is important to control blood in uremic patients suffering from hypertension in order to prevent congestive heart failure. Restriction on sodium and water intakes, frequent hemodialysis and/or appropriate administration of anti-hypertensive agents may be necessary for these patients.
