Detailed Description
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. Blood-pressure reduction is a proven, inexpensive strategy to prevent stroke with benefits widely-generalizable in developed and developing countries. No randomised trials have demonstrated the efficacy and safety of SBP reduction to prevent secondary vascular events after ischaemic stroke to levels of about 120mmHg compared with 130-139mmHg. Consequently, most guidelines recommend reduction of systolic blood pressure (SBP) less than 140mmHg.
Aim:
The aim is to conduct an initial pilot randomised trial in Ireland and 7 leading 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 trial, comparing safety, efficacy, and other feasibility measures of two target SBP goals (intervention 115-125 mmHg, control 130-139 mmHg).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Target systolic blood pressure 115-125 mmHg
Recommended target SBP 115-125 millimetres of mercury (mmHg).
|
The recommended target SBP will be 115-125 mmHg in the intervention arm. A medication algorithm based on the SPRINT trial protocol will be provided. The final choice and dose of antihypertensive treatment(s) will be at the discretion of the treating clinicians. If no contra-indications, indapamide or other thiazide diuretic and/or angiotensin-converting enzyme (ACE) inhibitor (perindopril or other) will be encouraged as initial therapy, with long-acting calcium-channel antagonists (eg.amlodipine) encouraged as third-line therapy. At scheduled face-to-face or remote follow-up, patients will have their home blood pressure monitoring diary reviewed by the study team. If SBP is out of the allocated target range, a prescription to titrate (up or down) antihypertensive medication will be given to the patient. |
