A Prospective Multicenter Registry on Coronary Function Tests, Organized by the Belgian Working Group on Coronary Microcirculation/Belgian Microcirculation Registry.

Observational University Hospital, Antwerp · NCT06089031

This study looks at how often doctors in Belgium use tests to check heart blood flow and related issues in patients, while also gathering information about their symptoms and quality of life.

What this trial studies

This prospective, multicenter registry aims to document the real-world application of coronary function tests in Belgium, focusing on bolus thermodilution measurements and invasive vasoreactivity tests. It will assess the frequency of these tests, their indications, and the prevalence of coronary microvascular dysfunction and vasospasm among patients. Data will be collected from medical files, including cardiovascular risk factors and follow-up information, with optional questionnaires on symptoms and quality of life. The study does not require specific visits, making it a practical observational approach.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for coronary function tests who can provide informed consent.

Not a fit: Patients who are pregnant or unable to provide consent, as well as those participating in other investigational trials, may not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could enhance understanding of coronary function testing and improve patient management for those with coronary microvascular dysfunction and vasospasm.

How similar studies have performed: While similar observational studies have been conducted, this registry focuses specifically on the real-world application of coronary function tests in Belgium, making it a novel approach.
