Intervention / Treatment
Detailed Description
ACS are the leading cause of mortality and morbidity in the western world. Despite recommended therapies, after experiencing an ACS episode patients still have an increased cardiovascular risk during follow up. In the CLIMA study OCT criteria of plaque vulnerability at non-culprit sites such as minimum luminal area <3.5mm2, fibrous cap thickness <75 µm, lipid arc extension >180° and macrophage infiltration was associated with an increased risk of cardiac death and myocardial infarction (HR 7.54, 95%CI 3.1-18.6).
Of the 36 OCT defined vulnerable plaques only 7 were associated with events showing a very low positive predictive value (19%). Yet, among the 577 plaques with macrophages accumulation only the 5.2% was associated with the endpoint. The lack of reliable information on plaque inflammation could represent the miss point to better link high risk plaques to plaque progression and/or rupture. Recent studies showed that inflammation in coronary plaques may be measured by means 68Ga-DOTATATE/PET targeting the somatostatin receptor subtype-2 selectively expressed by M1 macrophages.
Thus the investigators aim to evaluate the in vivo natural history of coronary plaques characterized from both the morphological (OCT) and inflammatory (68Ga-DOTATATE PET/CTCA) point of view in patients with ACS and at least 1 intermediated coronary lesion as assessed by FFR/iFR
