About this study
Official title: The Value of FAPI Imaging for the Prediction of Adverse Cardiovascular Events in Chronic Total Occlusion of Coronary Artery Disease (FACT-2 Trial)
Prospective, observational, single-center cohort study
Hypothesis Higher myocardial FAPI uptake in CTO patients predicts a greater incidence of major adverse cardiovascular events (MACE) within 12 months after PCI. FAPI PET/CT imaging is associated with plaque vulnerability features and may serve as a non-invasive marker for fibrotic activity and adverse cardiac remodeling.

Read the detailed description
Chronic total occlusion (CTO) of coronary arteries represents one of the most complex and challenging subsets of coronary artery disease and is associated with increased cardiovascular risk. While percutaneous coronary intervention (PCI) for CTO lesions has evolved substantially due to advances in imaging, devices, and operator experience, long-term prognostic evaluation remains suboptimal. In particular, no imaging biomarker currently allows non-invasive prediction of major adverse cardiovascular events (MACE) following CTO PCI.
Fibroblast activation plays a central role in myocardial fibrosis and atherosclerotic plaque instability, both of which contribute to adverse cardiovascular outcomes.
The fibroblast activation protein inhibitor (FAPI), labeled with radionuclides for PET/CT imaging, has recently emerged as a promising tool for quantifying fibrotic activity both in the myocardium and within coronary plaques. Preliminary data from the original FACT study showed that FAPI imaging may predict ventricular remodeling 6 months post-PCI. However, its long-term prognostic value and its role in detecting plaque vulnerability have not been fully evaluated in prospective studies.
The FACT-2 study is a prospective observational cohort study designed to evaluate whether FAPI PET/CT imaging can predict 1-year MACE in patients with CTO undergoing PCI. All enrolled patients will undergo baseline 18F-FAPI PET/CT scans prior to PCI and will be followed for 12 months post-intervention. The study aims to establish a FAPI-based risk stratification model, integrating FAPI uptake parameters with plaque morphology (via OCT and histopathology), serological fibrosis markers, and patient-reported quality of life scores.
The primary endpoint of the study is the incidence of MACE, defined as a composite of cardiac death, myocardial infarction, stroke, and urgent revascularization within one year of PCI. Secondary endpoints include all-cause mortality, repeat PCI events (including in-stent restenosis, target lesion/vessel revascularization, and de novo lesion intervention), and quality of life changes assessed by the Seattle Angina Questionnaire (SAQ).
In this study, FAPI uptake will be quantified by multiple parameters including total uptake volume (FAPI%), standardized uptake values (SUVmax, SUVmean), and target-to-background ratio (TBR). These parameters will be analyzed for correlation with clinical outcomes and histopathological features of plaque vulnerability (e.g., positive remodeling, microcalcification, lipid-rich necrotic core). The goal is to determine whether FAPI PET/CT can serve as a novel imaging biomarker for both myocardial and systemic fibrotic activity and stratify future cardiovascular risk.
By addressing the current evidence gaps in CTO prognosis and risk stratification, the FACT-2 study aims to provide scientific and clinical justification for incorporating molecular imaging into routine management of complex coronary artery disease. This study will also contribute to a more personalized treatment paradigm, bridging the gap between anatomical repair and biologically targeted intervention in cardiovascular medicine.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
FAPl lmagingDiagnostic test
Studies have shown that imaging with radionuclide-labeled fibroblast activation protein inhibitor (FAPl) is a reliable technique for detecting myocardial fibrosis and activated CFs in arteries. Preliminary evidence suggests that FAPl imaging can assess plaque characteristics and the status of myocardial fibrosis in various cardiovascular diseases.
| Study group | Role | What they receive |
|---|---|---|
| Patients with at least one untreated CTOat basal angiography | Total occlusion in any major coronary vessel or relevant side branches [reference vessel diameter >2.5 mm or as judged by two independent interventional cardiologists], with TIMI 0 in the distal segment and at least 3 months old Receives: Diagnostic Test: FAPl lmaging |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Major Adverse Cardiovascular Events (MACE)
MACE is defined as a composite of cardiac death, myocardial infarction, stroke, and urgent revascularization (including in-stent restenosis, target lesion revascularization, or target vessel revascularization). Events will be assessed through clinical follow-up and hospital record review.
Measured: 12 months after percutaneous coronary intervention (PCI)
Secondary outcomes (3)
All-Cause Mortality
Death from any cause, including cardiovascular and non-cardiovascular causes, occurring within 12 months after the index PCI procedure.
Measured: 12 months post-PCI, verified through national death registry and hospital records.
Change in Quality of Life
Assessed using the Seattle Angina Questionnaire (SAQ). Outcome domains include angina frequency, physical limitation, and treatment satisfaction. Comparison is made between baseline and 12-month follow-up.
Measured: At baseline and 12 months post-PCI.
Repeat Percutaneous Coronary Intervention (Repeat PCI)
Incidence of repeat PCI due to recurrent or new coronary lesions within 12 months, categorized as:
In-Stent Restenosis (ISR): ≥50% luminal narrowing in the original stented segment, with or without symptoms.
Target Lesion Revascularization (TLR): Reintervention at the original stent site due to restenosis or thrombosis.
Target Vessel Revascularization (TVR): Intervention in the same coronary artery, but outside the original stent site.
De Novo Lesion: New lesion in a vessel not treated during the index PCI. Confirmation based on follow-up angiography.
Measured: Within 12 months following the index PCI procedure.Angiographic confirmation
