Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Standard deviation of the error for heart rate | up to 24 hours | The standard deviation of the error between Reference and Aktiia.product for heart rate in bpm |
| Mean error for blood pressure | up to 24 hours | The mean error between the Reference and Aktiia.product for SYS and DIA in mmHg |
| Standard deviation of the error for blood pressure | up to 24 hours | The standard deviation of the error between Reference and Aktiia.product for SYS and DIA in mmHg |
| Mean absolute error for heart rate | up to 24 hours | The mean absolute error between the Reference (standard ambulatory blood pressure monitor) and Aktiia.product for heart rate in bpm |
| Mean error for heart rate | up to 24 hours | The mean error between the Reference and Aktiia.product for heart rate in bpm |
| Mean absolute error for blood pressure | up to 24 hours | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of patient's satisfaction for the two devices through a survey with multiple questions | up to 24 hours | 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. |
| Assessment of the calibration stability of Aktiia OBPM algorithms | 12 weeks | Use different calibration points going from 1 to 12 weeks |
| Assessment of systolic and diastolic blood pressure control during a 12 weeks cardiac rehabilitation program | 12 weeks | comparison of blood pressure determinations taken at the beginning and at the end of the program in ambulatory settings |
| Evaluation of the impact of ABPM induced stress on BP readings using inferential statistics. | 1 week | 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. |
