Brief Summary

The COOL-BP study is part of the Remote Hypertension Program and will investigate the data provided by Aktiia Bracelet (a cuffless Blood Pressure monitor at the wrist) when integrated into the Remote Hypertension Program. The COOL BP study aims to compare weekly and monthly Blood Pressure averages measured manually by traditional Home Blood Pressure Monitoring to those measured automatically by the Aktiia bracelet.

Outcome Measures

Primary Outcomes (2)

  • Diastolic and Systolic Pressures differences between weekly Diastolic and Systolic pressures averages provided by Home Blood Pressure Monitoring and by Aktiia 24h data.

    Diastolic and Systolic Pressures are measured weekly manually by traditional Home Blood Pressure Monitoring and continuously with the Aktiia bracelet.

    6 months

  • Diastolic and Systolic Pressures differences between monthly Diastolic and Systolic pressures averages provided by Home Blood Pressure Monitoring and by Aktiia 24h data.

    Diastolic and Systolic Pressures are measured monthly manually by traditional Home Blood Pressure Monitoring and continuously with the Aktiia bracelet.

    6 months

Secondary Outcomes (2)

  • Diastolic and Systolic Pressures Circadian profiles

    6 months

  • Quality of life surveys

Study Arms (1)

Patients with Aktiia bracelet

EXPERIMENTAL

This is a prospective open-label single arm study. Study participants will wear the Aktiia bracelet for 6 months and will continue in parallel the procedures of the Remote Hypertension Program.

Device: Aktiia Bracelet

Interventions

Aktiia Bracelet is a CE-marked medical device that will be used in accordance with its instructions for use. The optical signals at the wrist are recorded non-invasively by means by the Aktiia bracelet. The Blood Pressure measurements are further determined from these optical signals and are compared to weekly and monthly Blood Pressure averages measured manually by traditional Home Blood Pressure Monitoring.
