Evaluating Imaging Techniques for Heart Disease in Patients with Chronic Coronary Syndrome

Multimodality Imaging and Functional Lesion Assessment in Intermediate Grade Coronary Stenosis in Chronic Coronary Syndrome: MultiInter-CCS Study

Observational Medical University of Warsaw · NCT06261866

This study is testing how well two imaging techniques, FFR and OCT, can help people with chronic coronary syndrome and narrowed arteries understand their heart health better.

What this trial studies

This observational study aims to assess the diagnostic accuracy of various imaging techniques, specifically fractional flow reserve (FFR) and optical coherence tomography (OCT), in patients with chronic coronary syndrome who have intermediate coronary stenosis. It will analyze the correlation between functional indices and morphometric parameters, such as plaque type and minimal lumen area. The study will also explore how factors like age, sex, diabetes, and renal function affect these correlations. Participants will undergo both FFR and OCT examinations to provide comprehensive data on their coronary health.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with chronic coronary syndrome and intermediate grade coronary stenosis.

Not a fit: Patients with acute coronary syndrome or significant comorbidities such as severe heart failure or acute renal insufficiency may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the diagnostic approach for patients with chronic coronary syndrome, leading to better treatment decisions.

How similar studies have performed: Previous studies have shown promising results using similar imaging techniques for assessing coronary stenosis, indicating potential for success in this approach.
