About

The purpose of this pilot study is to assess the feasibility of implementing a home blood pressure self-management program in a population of recent stroke survivors in the Washington, D.C. area. The investigators hypothesize that hypertensive stroke survivors in the Washington, DC area who participate in the Home Blood Pressure Monitoring program will have a greater reduction in mean systolic blood pressure (SBP) from baseline to 3 months, as measured by automated office blood pressure (AOBP), as compared to usual care.

Full description

The purpose of this trial is to determine if a home blood pressure self-management (HBPS) program, including home monitoring and medication adjustments, is practical to use in recent stroke survivors and whether or not it is associated with lowering blood pressure after 3 months. Data from this trial may be used to do more research and may be used by doctors when seeing patients.This research is being done because high blood pressure, also called hypertension, is the leading risk factor for stroke. Lowering blood pressure (BP) has been shown to lower the risk of future strokes. The majority of stroke survivors continue to have uncontrolled BP. Currently, blood pressure (BP) is most often measured in the doctor's office. However, those single BP measurements are not the best picture of blood pressure over time and can be influenced by the stress of being in a doctor's office, known as the "white coat effect". This is why measuring BP at home may paint a more accurate picture of a patient's true long-term BP. Home blood pressure monitoring (HBPM) is recommended in the recently updated national hypertension guidelines. Home BP monitoring plus guided BP medication self-adjustments is associated with lower BP in patients with high blood pressure. The investigators believe that a HBPS program, including medication self-adjustment and home monitoring, may help to reduce blood pressure in patients with hypertension within 3 months.

32 participants in 2 patient groups

Home Blood Pressure Self Management

Experimental group

Description:

The HBPS group will check their blood pressure at home daily using a smart BP cuff with telemonitoring capability (Home Qardio) and guided to use a self-titration plan between office visits for persistently elevate blood pressures.

Treatment:

Device: Home Blood Pressure Monitoring Device (Qardio Arm)

Usual Care

Active Comparator group

Description:

The Usual Care group will have their blood pressure monitored and medications adjusted by their primary care provider.

Treatment:

Other: Primary Care Provider Blood Pressure Management
