Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have suffered a recent cardiovascular event such as ACS or stroke/TIA.

Probably not a fit

Patients with recent embolic events, severe heart dysfunction, or those unable to provide informed consent may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to evaluate the feasibility of using the nuclear tracer 18F-Florbetaben with PET imaging to identify inflammatory plaque in patients who have recently experienced acute coronary syndrome (ACS) or a stroke/transient ischemic attack (TIA). The study will enroll 24 patients with recent cardiovascular events and 6 control patients with known vascular disease but without recent events. Primary endpoints include measuring the uptake of Florbetaben in culprit versus non-culprit arteries, while exploratory objectives will assess correlations with other biomarkers and plaque burden. The study is conducted at a single center, the University of Ottawa Heart Institute.

Why it matters

Potential benefit: If successful, this study could improve the detection and management of inflammatory plaque in patients at risk for cardiovascular events.

How similar studies have gone: While this approach is novel in the context of using 18F-Florbetaben for this specific purpose, similar imaging techniques have shown promise in detecting vascular inflammation.
