Examining sex differences in coronary microvascular dysfunction in patients with non-obstructive coronary artery disease
Official title: Sex Difference of Coronary Microvascular Dysfunction Evaluated by Coronary Flow Reserve in Patients With Non-obstructive Coronary Artery Disease
Run by Korea University Anam Hospital · NCT06076551 · Data updated 2026-11-12
This study is trying to see if men and women with chest pain but no major blockages in their heart arteries have different issues with small blood vessels in the heart.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals experiencing typical or atypical chest pain with no significant coronary artery stenosis.
✕Probably not a fit
Patients with moderate valvular heart disease, congenital heart disease, or those with chronic renal failure may 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 observational study aims to evaluate the differences in coronary microvascular dysfunction between sexes in patients who experience chest pain but have no significant coronary artery stenosis. Patients will undergo adenosine stress echocardiography to assess coronary microvascular function by measuring coronary blood flow velocities at specified intervals after adenosine infusion. The study focuses on understanding how these differences may impact the management and treatment of microvascular angina.
Why it matters
Potential benefit: If successful, this study could lead to improved diagnosis and treatment strategies for patients suffering from microvascular angina, particularly by considering sex-specific differences.
How similar studies have gone: While there is ongoing research in coronary microvascular dysfunction, this specific focus on sex differences in patients with non-obstructive coronary artery disease is relatively novel.
