About this study

Participants ≥30 years old with hypertension and at least one of the following conditions: atrial fibrillation, diabetes, chronic kidney disease (stage 2 or higher), obesity (class 2 or higher), obstructive sleep apnea, coronary artery disease, hyperlipidemia, carotid stenosis (of 50% or greater), and/or congestive heart failure will be enrolled in a 6-month telehealth intervention focused on stroke risk reduction. The program includes use of home blood pressure monitors, smart pillboxes, wearable activity trackers, and a multidisciplinary team for personalized care. Primary endpoint is change in systolic blood pressure. Additional endpoints include diastolic BP, inflammatory markers (hs-CRP), and cardiovascular biomarkers (resting heart rate, HRV). The study is single-arm, non-randomized, and exploratory in design.

Treatment and study plan

Technology-enabled Telehealth Care Plan

Behavioral

Participants receive a 6 month personalized telehealth intervention via a multidisciplinary care team, delivering care via a secure digital platform, including education, risk assessment, lifestyle coaching, medical history review, and stroke risk reduction planning. The Healthie EHR is used for communication, documentation, and data integration. Syntrillo Navigators and neurology providers conduct onboarding, telemedicine visits, and coordination with patient's primary care providers and care team.

Blood Pressure Monitoring Device

Device

Participants will receive a cellular-enabled, FDA-cleared blood pressure monitor supplied by Tenovi. Blood pressure is measured twice daily during baseline and at least once daily throughout the 6-month intervention. Data is transmitted via a secure gateway to the Healthie EHR for real-time monitoring and analysis.

Tenovi Smart Pillbox

Device

Participants receive a connected 7-day smart pillbox that detects compartment openings and refills. Medication adherence data is uploaded in real time to a secure dashboard and integrated into the EHR.

Wearable Activity Trackers (Fitbit or Apple Watch)

Device

Participants will utilize a commercially available wearable activity tracker to monitor step counts, resting heart rate, and heart rate variability. This data is integrated into the EHR. Devices will be provided if participants do not already own one.

Healthie EHR

Other

HIPAA-compliant electronic medical record system used for participant management, secure communication, clinical documentation, and device data integration, consisting of custom workflows used for risk tracking and care planning.

Secure Messaging Platforms (TigerConnect, Weave, AirCall)

Other

Participants and providers may communicate using secure messaging platforms for appointment reminders, assessments, and care support, to enhance participation engagement and care coordination.

Antihypertensive Medication Management

Drug

Participants may be prescribed or have existing antihypertensive regimens adjusted (ACE inhibitors, beta blockers, calcium channel blockers, diuretics, etc) by neurologists or nurse practitioners based on individual risk assessments and clinical findings during the study. Changed will be recorded in EHR.

Statin Medication Management

Drug

Lipid-lowering medications, including statins, may be initiated or adjusted as part of participants' care plans. Medication use is guided by cardiovascular risk and AHA guidelines. Changed will be recorded in EHR.

Antiplatelet or Anticoagulant Therapy

Drug

Participants with atrial fibrillation or elevated cardiovascular risk may be started on or have changes to antiplatelet or anticoagulant therapy. Medication decisions are made by neurologist or nurse practitioners during telemedicine visits. Changed will be recorded in EHR.

Laboratory Blood Test Collection

Procedure

Blood samples may be collected at baseline and at 6 months to assess inflammation through high-sensitivity C-reactive protein.

Primary outcomes

  1. 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.

Secondary outcomes

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.
