Overview
The goal of this clinical trial is to evaluate the feasibility and effectiveness of a ring-type blood pressure measurement device compared to a 24-hour ambulatory blood pressure monitoring device in patients with hypertension or suspected hypertension. The main question it aims to answer is whether the 24-hour blood pressure measurement accuracy of the ring-type blood pressure monitor is similar to that of the 24-hour ambulatory blood pressure monitor. To participate, subjects must wear a ring blood pressure monitor and an ambulatory blood pressure monitor simultaneously for 24 hours.
Eligibility
Inclusion Criteria:
- Patients scheduled for 24-hour ambulatory blood pressure monitoring for diagnostic purposes among those suspected of having hypertension
- Confirmed hypertensive patients scheduled for 24-hour ambulatory blood pressure
monitoring for treatment purposes
- 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
- End-stage renal disease (patients undergoing dialysis)
