Overview
Brief Summary
This study will test the feasibility of a home blood pressure telemonitoring (HBPTM) system in patients with minor stroke or TIA in the past year. The telemonitoring system will consist of a blood pressure machine and an online survey to submit blood pressure measurements. The investigators want to test whether patients can persistently use the telemonitoring system with ease and whether telephone instructions for blood pressure medications from the research nurse can be correctly understood. A secondary purpose of this study is to look at the effects of telemonitoring in blood pressure and stroke recurrence.
Detailed Description
The investigators propose a two-year pilot study (TEC4Home Stroke) to assess the feasibility of using home telemonitoring technology in managing hypertension among patients with minor stroke/TIA (NIH Stroke Scale Score \<5) at the VGH Stroke Prevention Clinic (SPC). The Vancouver Stroke Program SPC receives 1200 referrals per year for assessment of patients with strokes or TIAs. Of the total number of patients referred to the SPC, 45% were deemed as hypertensive patients through any one of: (1) medical history of hypertension, (2) on antihypertensive medications or (3) having blood pressure measurements above 140/90 mm Hg during their assessment at the clinic. This project, which includes baseline assessments of home supports and cognition, will assess the specific needs of the post-stroke population in determining feasibility of HBPTM and nurse-led hypertension treatment. Previous studies of aggressive hypertensive control regimens have shown that it takes approximately six months to consistently achieve target pressures (SPRINT, SPS3). Thus in this feasibility study, participants will be monitored for 6 months using home telemonitoring technology.

Eligibility Criteria
Inclusion Criteria
- •Patients who had a minor stroke or TIA in the past year and seen at SPC.
- •Systolic hypertension at least 10 mm Hg above target, defined as any of:
- •A definite history of systolic hypertension before stroke as per CHEP (Canadian Hypertension Education Program) guidelines, or
- •Currently receiving antihypertensive medications, or
- •Any two documented SBP above 150 mm Hg (or above 140 mm Hg if diabetic) - either by history, on referral forms, or on an average of blood pressure measurements done during the patient's appointment at SPC
- •18 years or older
- •Informed consent from patient or substitute decision-maker
- •Able to comprehend medication instructions over the phone in English, or has a caregiver able to do so.
- •If patient is unable to directly participate in the Telehealth intervention (e.g. severe aphasia, has English as a second language, modified Rankin Scale score (mRS) \>4, a caregiver or family must be available to participate with the BP monitoring procedures and medication titration).
Exclusion Criteria
- •Patients admitted at long term care facilities or rehabilitation facilities (If admitted at rehabilitation facility, patient must be discharged prior to enrollment in the study)
- •Unable to comply with home blood pressure monitoring procedures for any other reason
- •Participation in other interventional (i.e., drug or device) clinical trials
- •Severe illness or another major illness that would affect ability to attend the study visits
- •Dialysis or diagnosis of end stage renal disease
- •Secondary hypertension (e.g. hypertension secondary to a known medical condition such as renal artery stenosis, pheochromocytoma, etc.)
- •Life expectancy \< 12 months
