Is this trial a fit for you?

Likely a good fit

Ideal candidates include women over 18 years old who experience chest pain and have been diagnosed with microvascular coronary dysfunction.

Probably not a fit

Patients with a history of cardiovascular, pulmonary, or neurological diseases, or those with hypertension, diabetes, or contraindications to cardiac MRI will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to explore the relationship between coronary microvascular dysfunction and heart relaxation in women experiencing chest pain but without obstructive coronary artery disease. It will involve 30 participants, including healthy individuals and women diagnosed with microvascular disease, who will undergo various stress maneuvers alongside advanced cardiac magnetic resonance imaging. The goal is to better understand the pathophysiology of microvascular coronary dysfunction and its impact on heart function.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnosis and treatment options for women suffering from microvascular coronary dysfunction.

How similar studies have gone: While this approach is novel in its specific focus on women with microvascular dysfunction, similar studies have shown promise in understanding coronary microvascular disease.
