Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	up to 24 hours
Primary	Mean error for blood pressure	The mean error between the Reference and Aktiia.product for SYS and DIA in mmHg	up to 24 hours
Primary	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	up to 24 hours
Primary	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	up to 24 hours
Primary	Mean error for heart rate	The mean error between the Reference and Aktiia.product for heart rate in bpm	up to 24 hours
Primary	Standard deviation of the error for heart rate	The standard deviation of the error between Reference and Aktiia.product for heart rate in bpm	up to 24 hours
Secondary	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.	1 week
Secondary	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.	up to 24 hours
Secondary	Assessment of the calibration stability of Aktiia OBPM algorithms	Use different calibration points going from 1 to 12 weeks	12 weeks
Secondary	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	12 weeks
