ClinConnect Summary

This clinical trial is testing a new ring-shaped device that measures blood pressure to see if it works as well as a standard 24-hour blood pressure monitor. The main goal is to find out if the readings from the ring device are accurate enough for patients with high blood pressure or those who might have it. To take part in the study, participants will need to wear both the ring device and the standard monitor for a full day.

To be eligible, participants should be adults who are either undergoing blood pressure monitoring for diagnosis or treatment of high blood pressure. However, some individuals may not qualify, such as those with certain heart conditions, a high body weight (BMI of 30 or above), or those who are pregnant. By participating, individuals will help researchers understand if this new device can offer a simpler way to track blood pressure at home.

• • Either criterion 1 or 2 are planned to be selected as study participants.
• Exclusion Criteria:
• • Participants who do not consent to the study
• • Individuals with a Body Mass Index of 30 or above (there's a concern of measurement errors as the standard 24-hour ambulatory blood pressure cuffs may not fit well)
• • Pregnancy
• • Baseline heart disease patients: individuals with a history of hospitalization due to heart failure, valvular disease, or myocardial infarction
• • Patients diagnosed with atrial fibrillation on a 12 lead EKG within the past 6 months
