Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean absolute error for blood pressure
Time Frame: 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
up to 24 hours
Mean error for blood pressure
Time Frame: up to 24 hours
The mean error between the Reference and Aktiia.product for SYS and DIA in mmHg
up to 24 hours
Standard deviation of the error for blood pressure
Time Frame: up to 24 hours
The standard deviation of the error between Reference and Aktiia.product for SYS and DIA in mmHg
up to 24 hours
Mean absolute error for heart rate
Time Frame: up to 24 hours
The mean absolute error between the Reference (standard ambulatory blood pressure monitor) and Aktiia.product for heart rate in bpm
up to 24 hours
Mean error for heart rate
Time Frame: up to 24 hours
The mean error between the Reference and Aktiia.product for heart rate in bpm
up to 24 hours
Standard deviation of the error for heart rate
Time Frame: up to 24 hours
The standard deviation of the error between Reference and Aktiia.product for heart rate in bpm
up to 24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evaluation of the impact of ABPM induced stress on BP readings using inferential statistics.
Time Frame: 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.
1 week
Evaluation of patient's satisfaction for the two devices through a survey with multiple questions
Time Frame: 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.
up to 24 hours
Assessment of the calibration stability of Aktiia OBPM algorithms
Time Frame: 12 weeks
Use different calibration points going from 1 to 12 weeks
12 weeks
Assessment of systolic and diastolic blood pressure control during a 12 weeks cardiac rehabilitation program
Time Frame: 12 weeks
comparison of blood pressure determinations taken at the beginning and at the end of the program in ambulatory settings
