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
Change in Systolic Blood Pressure
Time Frame: Baseline to 6 months
This measure evaluates the average change in systolic blood pressure (SBP), which is the pressure in the arteries when the heart beats. Blood pressure is measured by participants at home using a Tenovi FDA-cleared digital blood pressure monitor. Baseline SBP is calculated using the first 10 valid readings taken during the initial week of monitoring. The 6-month value is calculated from the last 10 valid readings taken in the final week of the intervention. The study aims to observe a reduction of at least 10 mmHg in average SBP over the intervention period.
Baseline to 6 months

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
Change in Diastolic Blood Pressure
Time Frame: Baseline to 6 months
This measure evaluates the average change in systolic blood pressure (SBP), which is the pressure in the arteries when the heart beats. Blood pressure is measured by participants at home using a Tenovi FDA-cleared digital blood pressure monitor. Baseline SBP is calculated using the first 10 valid readings taken during the initial week of monitoring. The 6-month value is calculated from the last 10 valid readings taken in the final week of the intervention. The study aims to observe a reduction of at least 10 mmHg in average SBP over the intervention period.
Baseline to 6 months
Change in Systolic Blood Pressure Variability
Time Frame: Baseline to 6 months
This measure assesses the variability of systolic blood pressure (SBP) as measured by the standard deviation (SD) of SBP readings. Variability is calculated from 20 readings collected at baseline (first 2 weeks) and another 20 readings at the end of the intervention (final 2 weeks). Measurements are taken using the Tenovi home blood pressure monitor. The target is a 10% reduction in the standard deviation of SBP values, indicating more stable blood pressure control.
Baseline to 6 months
Change in Pulse Pressure
Time Frame: Baseline to 6 months
This measure evaluates the change in pulse pressure (PP), defined as the difference between systolic and diastolic blood pressure. PP is a marker of arterial stiffness and cardiovascular risk. It is calculated from 20 home blood pressure readings collected at the start and again at the end of the 6-month intervention. Measurements are obtained using the Tenovi device. The study target is a reduction of at least 5 mmHg in average pulse pressure.
Baseline to 6 months
Change in High-Sensitivity C-Reactive Protein (hs-CRP)
Time Frame: Baseline to 6 months
This measure examines changes in high-sensitivity C-reactive protein (hs-CRP), a blood marker of systemic inflammation and cardiovascular risk. hs-CRP levels are measured from blood samples collected at baseline and again at the 6-month time point. The study aims to observe a mean reduction of at least 20% in hs-CRP concentration over the course of the intervention.
Baseline to 6 months
Change in Resting Heart Rate
Time Frame: Baseline to 6 months
This measure evaluates the change in resting heart rate (RHR), defined as the number of heartbeats per minute when the body is at rest. RHR is measured using participant-worn Fitbit or Apple Watch devices. The average RHR is calculated from 20 data points collected during the initial monitoring period and compared with 20 data points collected in the final weeks of the intervention. The study aims to observe a mean decrease of at least 5 beats per minute in resting heart rate.
Baseline to 6 months
Change in Heart Rate Variability
Time Frame: Baseline to 6 months
This measure tracks changes in heart rate variability (HRV), a measure of autonomic nervous system function. HRV is assessed using the standard deviation of NN intervals (SDNN), collected from data provided by Fitbit or Apple Watch wearable devices. Baseline SDNN is calculated from 40 measurements during the first 2 weeks, and compared to 40 measurements taken during the final 2 weeks of the study. The target is a 10% or greater increase in average SDNN over the study period.
