Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older with acute or stable coronary syndromes scheduled for non-emergent invasive angiography and OCT evaluation.
✕Probably not a fit
Patients without detectable PCCT-defined high-risk plaque features or those unlikely to experience events based on other risk factors may see limited benefit.

What this trial studies
This prospective, single-center observational study enrolls adults with acute or stable coronary syndromes who are planned for invasive angiography and OCT. Participants undergo a contrast-enhanced photon-counting detector CT to identify high-risk plaque features, and within about 30 days have invasive angiography with OCT for cross-sectional comparison. The study assesses whether PCCT-detected high-risk plaque predicts major adverse cardiovascular events or revascularization during follow-up, and compares PCCT findings with OCT results using blinded core laboratories. Data from the imaging modalities will be analyzed to evaluate diagnostic performance relative to clinical outcomes. The overall goal is to determine if non-invasive PCCT can help identify patients at higher risk for future events.
Why it matters
Potential benefit: If successful, PCCT could help identify patients at higher risk for future heart events using a non-invasive test.
How similar studies have gone: Previous imaging studies show promise linking plaque features to risk, but direct use of PCCT-defined high-risk plaque to predict events is still being established.
