Arterial stiffness and interdialytic weight gain influence ambulatory blood pressure patterns in hemodialysis patients

摘要

Besides disturbances in arterial rhythms, patients with ESRD also have profound abnormalities in the structure of conduit blood vessels (1). Alteration in arterial structure can be clinically detected by increased arterial stiffness that is in part due to vascular calcification but also attributable to an increase in pulse wave reflection, which results in elevated systolic, lowered diastolic, and therefore amplified pulse pressure (1). The magnitude of arterial stiffness increment is related to mortality in patients with ESRD (8, 10).
