What researchers measure

Primary outcomes

  1. Mean absolute error for blood pressure

    The mean absolute error between the Reference (standard ambulatory blood pressure monitor) and Aktiia.product for systolic (SYS) and diastolic (DIA) blood pressure in mmHg

    Time frame: up to 24 hours

  2. Mean error for blood pressure

    The mean error between the Reference and Aktiia.product for SYS and DIA in mmHg

    Time frame: up to 24 hours

  3. Standard deviation of the error for blood pressure

    The standard deviation of the error between Reference and Aktiia.product for SYS and DIA in mmHg

    Time frame: up to 24 hours

  4. Mean absolute error for heart rate

    The mean absolute error between the Reference (standard ambulatory blood pressure monitor) and Aktiia.product for heart rate in bpm

    Time frame: up to 24 hours

  5. Mean error for heart rate

    The mean error between the Reference and Aktiia.product for heart rate in bpm

    Time frame: up to 24 hours

  6. Standard deviation of the error for heart rate

    The standard deviation of the error between Reference and Aktiia.product for heart rate in bpm

    Time frame: up to 24 hours

Secondary outcomes

  1. Evaluation of the impact of ABPM induced stress on BP readings using inferential statistics.

    Aktiia values acquired during the first day (with ABPM) will be compared to values acquired during other days of the week and a t-test will be performed. The analysis will be repeated for night values.

    Time frame: 1 week

  2. Evaluation of patient's satisfaction for the two devices through a survey with multiple questions

    10-points likert scale survey, an agree-disagree scale with minimum 0 and maximum 10. Minimum value means strong disagreement, maximum value means strong agreement.

    Time frame: up to 24 hours

  3. Assessment of the calibration stability of Aktiia OBPM algorithms

    Use different calibration points going from 1 to 12 weeks

    Time frame: 12 weeks

  4. Assessment of systolic and diastolic blood pressure control during a 12 weeks cardiac rehabilitation program

    comparison of blood pressure determinations taken at the beginning and at the end of the program in ambulatory settings

    Time frame: 12 weeks
