E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study will be to test the association between the intensity of 68Ga-DOTATATE uptake in coronary plaques quantified with PET at M0 and the absolute progression rate of coronary artery calcium scoring (CACS) measured between the CT acquired at M0 and after 2 years. |
L'objectif primaire de cette étude sera de tester la corrélation entre l'intensité de fixation de 68Ga-DOTATATE dans les plaques coronaires mesurées sur la TEP initiale (M0), et la vitesse de progression du score calcique coronaire mesurée en comparant les valeurs mesurées sur le scanner initial (M0) et celui réalisé 2 ans après l'inclusion (M24) |
|
E.2.2 | Secondary objectives of the trial |
1. to identify a threshold for the intensity of 68Ga-DOTATATE-PET (mean TBR) in coronary plaques quantified with PET at M0 associated with a higher probability of clinical coronary events after a 2-year follow-up, defined by the composite of cardiovascular death, acute coronary syndromes and ischemia-driven coronary revascularization at two years. |
1. identifier une valeur seuil d’intensité de 68Ga-DOTATATE (TBR moyen) en TEP dans les plaques coronaires associée à une augmentation de la probabilité d’événements cardiovasculaires (critère combiné): mortalité, syndrome coronarien aigu, revascularisation pour nouvelle ischémie documentée après un suivi de 2 ans. |

E.5 End points |
E.5.1 | Primary end point(s) |
Maximum TBR will be measured in 2D ROIs drawn around all major epicardial coronary arteries (diameter >2 mm) identified on the coronary CTA and averaged into a mean TBR value per patient. The increase in CACS will be measured as the difference between the CACS measured at M0 and 2 years later.
|
Critère d'évaluation principal: une valeur globale de TBR sera calculée pour chaque patient comme la moyenne des TBR maximaux mesurés sur la TEP dans des régions d'intérêts 2D placées le long des axes coronaires identifiés par coroscanner. L'augmentation du score calcique coronaire (SCC) sera calculée comme la différence entre le score mesuré initialement et deux ans plus tard.
