Identifying biomarkers in migraine patients with a heart condition

Migraine With Aura and Causal or Incidental Patent Foramen Ovale (PFO): Identification of Biomarker(s) to Select Patients Who Would Most Benefit From PFO Closure. The MANET Study

Observational Centro Cardiologico Monzino · NCT06046508

This study is testing if certain blood markers can help doctors tell the difference between migraine patients with a specific heart condition and those who have it by chance.

What this trial studies

This multicenter observational study aims to determine if a specific prothrombotic platelet phenotype can differentiate migraine patients with a patent foramen ovale (PFO) from those with incidental PFO. The study will enroll patients with PFO who meet specific criteria and will conduct various evaluations, including thrombophilic screening and imaging studies. Blood samples will be collected to assess platelet reactivity and endothelial function, with analyses performed before and after PFO correction. The goal is to identify biomarkers that could guide treatment decisions for migraine patients with PFO.

Who should consider this trial

Good fit: Ideal candidates include patients with a patent foramen ovale who have experienced a stroke or transient ischemic attack and meet specific inclusion criteria.

Not a fit: Patients with conditions such as severe chronic kidney disease or those requiring long-term anticoagulant therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more targeted interventions for migraine patients with PFO, potentially improving their treatment outcomes.

How similar studies have performed: While this approach is novel in its specific focus on migraine and PFO, similar studies have shown promise in identifying biomarkers for other conditions.
