Understanding the connection between heart and brain in acute ischemic stroke

The Bern Heart and Brain Interaction Study - Interaction Between Brain and Heart in Acute Ischemic Stroke

Observational Insel Gruppe AG, University Hospital Bern · NCT03720522

This study looks at how heart problems can cause strokes and aims to improve the way doctors diagnose heart attacks in stroke patients to help them get better treatment.

What this trial studies

This observational study investigates the relationship between heart conditions and acute ischemic stroke, focusing on how heart attacks can lead to strokes and vice versa. It aims to improve the accuracy of diagnosing heart attacks in patients who have suffered a stroke by utilizing cardiovascular MRI and other assessments. The study will involve collecting blood and urine samples to analyze the underlying mechanisms of these conditions. By identifying the causes of stroke more precisely, the research seeks to enhance treatment strategies and reduce the risk of recurrence.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 85 who have experienced an acute ischemic stroke within the last 12 hours.

Not a fit: Patients who are pregnant, have severe renal failure, or cannot undergo MRI due to standard contraindications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better diagnostic methods for heart attacks in stroke patients, improving treatment outcomes.

How similar studies have performed: While the interaction between heart and brain in stroke patients is a recognized area of interest, this specific approach using cardiovascular MRI is relatively novel and has not been extensively tested in prior studies.
