The relationship between anemia and blood pressure in chronic hemodialysis patients

—Studies of hemodynamics

Abstract

We noticed the downward tendency of blood pressure in chronic hemodialysis patients whose anemia was improving. To evaluate the relationship between anemia and blood pressure in chronic hemo-dialysis patients, we examined hemodynamics on 26 patients, and found negative correla-tion between hematocrit value (Ht) and blood volume (BY), while positive one between BV and mean blood pressure. These results indicate that the decreasing of BV coincides with the improvement of anemia, and lowers blood pressure. Although the cause of the reduction of BY was not conclusive, we speculated that the increasing of fatty tissue weight due to increment of diet, frequently observed in patients whose anemia was improving, might decrease BY consequently when their weights kept constant.
