Arms Assigned Interventions
Active Comparator: All Study Participants
All enrolled participants were randomized to receive Carvedilol or Placebo in a 2-way crossover design. Each intervention was administered over 8 weeks before switching to the alternative intervention. The study was terminated early, and data were not unblinded so participants cannot be reported separately.
Other: Carvedilol and Placebo
All enrolled participants were randomized to receive Carvedilol or Placebo in a 2-way crossover design. Each intervention was administered over 8 weeks before switching to the alternative intervention. The study was terminated early, and data were not unblinded so participants cannot be reported separately.

Detailed Description:

The effect of Carvedilol CR on Micro T-Wave Alternans will be assessed in 30 hypertensives with stage 4 or 5 chronic kidney disease utilizing a cross-over design and contrasting no treatment against active treatment periods of 8 weeks.
