Does catheter-based renal denervation reduce ambulatory heart rate in hypertensive patients not receiving anti-hypertensive medications?
Catheter-based renal denervation significantly reduces morning heart rate at 3 months compared to sham in unmedicated hypertensive patients, and higher baseline heart rate may predict greater blood pressure reduction.
Average and minimum morning HR were significantly reduced at 3 months for RDN compared with sham patients. A baseline 24-h HR above the median predicted greater BP reductions and may allow physicians to select patients likely to respond to the procedure.
Böhm et al. (Tue,) studied this question.
