About

In this study, a wristband that monitors hearth rhythm and blood pressure is assessed in free living conditions.

Two groups of patients are being recruited: patients receiving an EKG holter and patients receiving an automatic blood pressure monitor. Patients wear the wristband for 28 days. During this time, the number of atrial fibrillation episodes detected by the wristband is being counted, which is to be compared with the number of episodes detected by the holter. Also, blood pressure is measured continuously, which is to be compared with daily blood pressure measurements using a conventional blood pressure cuff.

Full description

Background of the study:

Wearables have the potential to monitor patients remotely. The Corsano CardioWatch 287-2 is such a medical device that can monitor atrial fibrillation and long-term blood pressure. The device has been validated using clinical trials in hospitals, but validation in the intended remote setting is lacking.

Objective of the study:

Primary objective: To compare the number of episodes of atrial fibrillation detected by the Corsano CardioWatch 287-2 during 28 days of use with the number of episodes of atrial fibrillation detected by conventional Holter monitoring during 48 hours of use (standard care).

Secondary objective: To assess the difference in blood pressure measurements obtained by the Corsano CardioWatch 287-2 and the conventional cuff blood pressure monitor over a period of 28 days; to assess the usability of the Corsano CardioWatch 287-2 from a patient perspective.

Study design:

Group A:

Conventional 24 hour EKG holter monitoring will be compared to 28 day continuous monitoring by the Corsano CardioWatch 287-2 to assess whether the percentage of patients in whom atrial fibrillation is detected will increase. Detection of atrial fibrillation with the Corsano CardioWatch 287-2 is done by optical photoplethysmography (PPG), after which atrial fibrillation is confirmed with a 30-second ECG measurement.

Additionally, conventional cuff blood pressure will be compared to blood pressure measured by the Corsano CardioWatch 287-2 to validate free-living blood pressure monitoring. Patients will measure their blood pressure daily with a cuff blood pressure measurement device. The measurements at day 7, 14, 21 will be used to reinforce the Corsano blood pressure algorithm. The remaining measurements will be used to compare the blood pressure with the values measured by the Corsano CardioWatch 287-2 to assess accuracy.

Group B:

Conventional automatic cuff blood pressure measurement will be compared with the Corsano CardioWatch 287-2 for 24-48 hours. The automatic cuff blood pressure monitor will take a blood pressure reading every 30 minutes. Each reading will be compared with the Corsano CardioWatch 287-2 reading.

Study population:

Patients receiving a 24 hour EKG holter or an ambulant blood pressure device after visiting the cardiologist's outpatient clinic.

Primary study parameters/outcome of the study:

Absolute percentage increase of patients in whom at least one event of atrial fibrillation is detected by the Corsano CardioWatch 287-2 during 28 days of monitoring, compared to a conventional EKG holter during 24-48 hours of monitoring.

Secundary study parameters/outcome of the study (if applicable):

1. Mean blood pressure difference and its SD between blood pressure measured by the Corsano CardioWatch 287-2 and blood pressure measured by a conventional oscillometric blood pressure cuff.
2. Usability of the Corsano CardioWatch 287-2 in a remote care setting as determined by a questionnaire.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness:

At the cardiologist's office, Group A and B patients receive 3 blood pressure measurements. These are performed by a nurse. Group A will take daily blood pressure readings of themselves at home. If atrial fibrillation is detected by the wristband, Group A patients will be asked to take an ECG. Finally, Group A patients will be asked once to complete a questionnaire. Group B only has to wear the wristband for 24 to 48 hours as an additional burden in addition to the aforementioned initial measurements.
