NCT06584331

Brief Summary

The goal of this clinical trial is to verify the hemodynamic and biomarker responses of beetroot juice intake in postmenopausal women with hypertension. The main questions it aims to answer are: Is beetroot juice dose related to better hemodynamic responses in hypertensive postmenopausal women? Is beetroot juice dose related to better oxidative stress profile responses in hypertensive postmenopausal women? The investigators will conduct a parallel clinical study with 10 days of intervention, in which 48 women will be randomized into 3 groups: 1) Two shots of beetroot juice intake per day (800mg of NO3-); 2) One shot of beetroot juice intake per day (400mg of NO3-); 3) placebo intake (beetroot juice without NO3-).

Outcome Measures

Primary Outcomes (1)

  • Blood Pressure

    Volunteers will undergo blood pressure tests at the beginning, in the middle and after the 10 days of intervention. To assess blood pressure (BP), researchers will use the Dyna Mapa + Cardius® device, programmed with measurements to be taken every 20 min. Together with this device, the volunteers filled out a daily record of activities such as sleep, work, food, or any event that could interfere with BP or measurements. In a standardized manner, the device was set at 7 a.m., and measurements were considered valid when 24h of monitoring were obtained. Resting BP was measured with the same device after 15 min of rest in a sitting position, and for the analysis of the pressure curve, time 0 was adopted when the monitor was placed. Sytolic BP, diastolic BP, and mean BP in periods of awake, sleep and 24 h were analyzed.
