Imaging assessment of chronic total coronary occlusion

The Clinical Value of FAPI Imaging in Assessing Chronic Total Occlusion Lesions in Patients with Coronary Heart Disease (FACT Trial)

Beijing Chao Yang Hospital · NCT06655922

This study looks at how a special imaging technique can help understand heart tissue changes in patients with blocked arteries to see if it can improve their treatment outcomes.

What this trial studies

This observational registry includes patients with at least one chronic total coronary occlusion (CTO) identified through coronary angiography or cardiac computed tomography angiography. The study aims to evaluate the role of fibroblast activation in the progression of myocardial fibrosis and its impact on patient prognosis. By utilizing FAPI imaging, the study seeks to provide insights into the activation of cardiac fibroblasts in CTO patients, which has been challenging to assess reliably in vivo. The findings may help improve procedural success rates and patient outcomes in those undergoing percutaneous coronary intervention (PCI) for CTO.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years with at least one untreated chronic total coronary occlusion requiring PCI.

Not a fit: Patients with severe hepatic dysfunction, severe chronic kidney disease, or life expectancy of less than one year may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of myocardial fibrosis in CTO patients and improve treatment strategies, leading to better patient outcomes.

How similar studies have performed: Other studies have shown promise in using imaging techniques to assess fibroblast activity, suggesting potential success for this approach.
