Intradialytic hypertension and its association with endothelial cell dysfunction.

ABSTRACT:

Background and objectives

Intradialytic hypertension is associated with adverse outcomes, yet the mechanism is uncertain. Patients with intradialytic hypertension exhibit imbalances in endothelial-derived vasoregulators nitric oxide and endothelin-1, indirectly suggesting endothelial cell dysfunction. We hypothesized that intradialytic hypertension is associated in vivo with endothelial cell dysfunction, a novel predictor of adverse cardiovascular outcomes.

Design, settings, participants, & measurements

We performed a case-control cohort study including 25 hemodialysis (HD) subjects without (controls) and 25 with intradialytic hypertension (an increase in systolic BP pre- to postdialysis ≥10 mmHg ≥4/6 consecutive HD sessions). The primary outcome was peripheral blood endothe
