Clinical Trial Summary

This study evaluates the impact of mindfulness-based stress reduction (MBSR) on sympathetic nerve activity and arterial stiffness. The investigator's central hypothesis is that MBSR will reduce sympathetic activity and arterial stiffness.

Description:

This study will recruit male and female subjects with elevated blood pressure who will participate in a randomized, active control study to examine the impact of mindfulness-based stress reduction (MBSR) on blood pressure, muscle sympathetic nerve activity and arterial stiffness. The study will utilize established techniques for assessing blood pressure patterns (24-hour ambulatory monitoring), peripheral sympathetic activity (microneurography) and vascular stiffness (applanation tonometry) in humans. This study includes a stress management education class for the active control.
