Atrial Fibrillation, Empowerment, Hypertension, Ischemic Stroke, Transient Ischemic Attack
Conditions
Brief summary
The CARDIOSTROKE is a randomized trial comparing mobile-device assisted control of hypertension together with screening of occult atrial fibrillation to standard care in patients with recent ischemic stroke or transient ischemic attack.
Detailed description
Atrial fibrillation (AF) and hypertension are among the main treatable risk factors for ischemic stroke and transient ischemic attack (TIA). Detecting paroxysmal atrial fibrillation in stroke patients is challenging, but highly relevant since anticoagulation can effectively reduce the risk of recurrent strokes. Furthermore, hypertension remains poorly controlled even after stroke despite multiple available treatment options. In the CARDIOSTROKE trial, the investigators aim to randomize 405 patients with recent ischemic stroke or TIA into (1) standard diagnostic work-up, follow-up and treatment (control group) and (2) 3-week ECG monitoring to detect occult AF and self-monitoring of blood pressure with mobile-device-assisted self-titration of antihypertensive medication (intervention group). Randomization will occur 2:1 into control and intervention groups. The co-primary outcomes include (1) incidence of new-onset AF and (2) difference in the mean blood pressure at 12-months.
Interventions
A 3-week continuous ECG monitoring to detect occult AF.
One-week monthly self-monitoring of BP and self-titration of antihypertensive medication according to a pre-specified protocol, assisted with a mobile device application.
