Why the study?
Does adjustment of dry weight based on bioimpedance analysis improve ambulatory blood pressure in hemodialysis patients?
Does adjustment of dry weight based on bioimpedance analysis improve ambulatory blood pressure in hemodialysis patients?
BIA-guided dry weight adjustment may improve ambulatory BP in hemodialysis; hypothesis-generating and requires randomized confirmation.
Background: Hypertension is a common problem for hemodialysis patients and is associated with an increased cardiovascular mortality. We analyzed ambulatory blood pressure (ABP) in hemodialysis patients and investigated if an adjustment of dry weight can be used to control blood pressure. Methods: ABP was measured for twenty-four hours after hemodialysis. A bioimpedance Analysis (BIA) was conducted. Patients were divided into two groups by the edema index. A normohydration (NH) group included patients with the edema index less than 0.40, and an overhydration (OH) group included patients with the edema index 0.40 or more. We accordingly adjusted the dry weight based on BIA results. Results:
