European Blood Pressure Intensive Control After Stroke

Background: Stroke is the third leading cause of global death, the leading cause of acquired disability and contributes substantially to dementia, cognitive decline, and healthcare costs. Global epidemiological studies such as INTERSTROKE and the Global Burden of Disease study estimated that hypertension is the leading modifiable risk factor for stroke, with a population attributable risk of approximately 50%. Recurrent vascular events (stroke, coronary events, vascular death) cause significant morbidity in ischaemic stroke survivors, affecting approximately 30% at 5 years. High rates of failure to achieve guideline BP targets (\<130mmHg) are reported in clinical practice for patients following ischaemic stroke or TIA. Home blood pressure measurement and telemonitoring is recognised as acceptable to patients from previous studies, and some trials have noted a significant reduction in BP at 12 months. The latest ESO guidelines note continued uncertainty over the use of out-of-office blood pressure measurements for adult patients with ischaemic stroke or TIA due to insufficient data. This trial will recruit patients with recent stroke/TIA events with systolic BP ≥140 mmHg and randomise them to standard of care or home BP monitoring with telemonitoring and medication titration. The study hypothesis is that home BP measurement and telemonitoring with medication titration may lead to improved BP control compared to standard of care clinical practice. Aim: The aim is to conduct an initial pilot randomised trial in Ireland and European centres involved in the European Stroke Organisation Trials Alliance. This feasibility study will assess key design aspects and establish trial governance, data management, and procedures in preparation for a larger definitive trial. Methods: Design: Prospective, open-label, blinded endpoint assessed (PROBE) randomised, parallel group pilot/feasibility clinical trial, comparing BP patient self-measurement and telemonitoring with office-based monitoring (standard of care) for improved BP control after ischaemic stroke/TIA.
