About this trial
The goal of this observational study is to assess the feasibility of classifying people whose blood pressures are within hypertensive range using a machine-learning approach based on features derived from smartphone video data recorded at the patient's fingertips. The main question\[s\] it aims to answer are:
Is a smartphone a reliable device for high blood pressure screening ? Is a smartphone a reliable device for blood pressure monitoring ? Participants will record their blood pressure with a smartphone at their fingertips and with an approved cuff device, 3 times in the morning and 3 times in the evening for 7 days. There will be two groups, a volunteer presumed healthy, and a volunteer addressed for a Home Blood pressure monitoring with the diagnosis of hypertension suspected.
Researchers will compare the two groups to see if the smartphone can be reliable in terms of diagnosis and monitoring of the blood pressure comparing to a standard cuff device.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Informed consent as documented by signature
Men or women older than 18 years old
Good understanding of written and oral speaking used at the center where the study will be carried out
Disqualifiers
Patients that cannot sign informed consent
Patients in emergency situation, are not legally competent, cannot understand the situation or are vulnerable
Unable to participate due to pain or stress [12]
Known or suspected non-compliance (e.g. drug or alcohol abuse, language problems, psychological disorders, dementia)
Trial population
For this study, the aim is to reach balanced classes, with at least 40% of non-hypertensive patients and 40% of hypertensive patients. In order to approach such distributions, both healthy volunteers and patients suspected of hypertension visiting the CHUV Hypertensive Unit for diagnosis confirmation will be recruited.
