Mechanisms and Treatment of Intradialytic Hypertension
Blood Pressure, Endothelial Cell Dysfunction, and Outcomes in Dialysis Patients
  1. To determine in a cross sectional case-controlled cohort study of 50 hemodialysis patients if blood pressure elevations with hemodialysis are associated with decreased endothelial cell function (measured by brachial artery flow mediated dilation and endothelial progenitor cell number), both of which are novel mechanistic markers in the causal pathway for detrimental cardiovascular outcomes; and
  2. To determine if lowering blood pressure with carvedilol in 25 ESRD subjects with blood pressure elevations with hemodialysis can improve endothelial cell dysfunction as a surrogate mechanistic marker for improving cardiovascular outcomes.

Interventional
Phase 4
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Intradialytic Hypertension
Drug: Carvedilol
Carvedilol 6.25 mg BID titrated weekly to maximum of 50 mg bid
  • No Intervention: Control
    Patients without intradialytic hypertension defined as average pre to post hemodialysis SBP falling >10 mmhg for more than 4/6 of the last dialysis treatment sessions
  • Active Comparator: Intervention
    Patients with intradialytic hypertension defined as average pre to post hemodialysis SBP elevation of >10 mmhg for more than 4/6 of the last dialysis treatment sessions
    Intervention: Drug: Carvedilol
