Clinical and OCT data will be included in the register according to the dataset.The primary endpoint will be the correlation of OCT characteristics with incidence of major adverse cardiovascular events (MACEs defined as the composite of death from cardiac causes, non- fatal MI, clinically driven target vessel revascularization (TVR), or re-hospitalization due to unstable or progressive angina according to Braunwald Unstable Angina Classification) and clinical baseline characteristics.\n\nIn particular subanalysis will be performed in the following subgroups: culprit plaque, not culprit plaque in culprit vessel, not culprit plaque in different vessel.\n\nSecondary end-point will be to evaluate how OCT analysis changed interventional cardiology approach in culprit plaque definition and coronary stenting respect the coronary angiography alone.', 'detailedDescription': 'INTRODUCTION. Pathophysiology of Acute Coronary Syndrome (ACS) deeply differs from those of stable patients, mainly due to peculiar features of plaque. Interestingly, most of the lesions triggering an acute ischemic event, usually defined "culprit lesions" are not angiographically severe, but present with mild stenosis. However, when evaluated at autopsy or with intracoronary imaging, they show often a pro-thrombotic pattern, with thin cap fibroatheroma, soft plaques and thrombus, prone to rupture.\n\nPatients without culprit plaque rupture (CPR) exhibit different mechanisms of instability including thrombus at the site of plaque erosion, or intense vasoconstriction of epicardial arteries or coronary microcirculation disfunction.\n\nIn this setting, in the last years Optical Coherence Tomography (OCT) has emerged as the most accurate instrument for intracoronary evaluation. Due to a resolution of approximately 10-20 µm it has been largely exploited in the evaluation and characterization of plaque features, both in stable and acute coronary artery disease.\n\nOn the other hand, despite recent evidences, characteristics of culprit plaque in different subset of patients are not well defined. Moreover clinical significance of plaque characteristics is unknown.\n\nMETHODS The OCT-FORMIDABLE register will include with a retrospective fashion all consecutive patients that perform OCT on culprit and not culprit plaque in any subset in patients with ACS. Clinical and OCT data will be included in the register according to the dataset.\n\nSAMPLE SIZE: the recent paper of Niccoli et al showed a percentages of plaque rupture of 60% in ACS. According to the paper by Pedruzzi et al, at least 100 patients are needed to evaluate independent predictive power of clinical presentation (STEMI vs NSTEMI vs UA), diabetes mellitus, previous use of aspirin, of statin and age.\n\nOCT ANALYSIS Different OCT system analysis and technique (different pullback velocity 75 mm vs 54 mm, contrast mediated or ringer lactate injection) will be reported. Each center will evaluate the OCT image by internal committee composed by at least two people. In case of discordance an external opinion will be required.\n\nPlaque rupture will be defined as the presence of fibrous cap discontinuity leading to a communication between the inner (necrotic) core of the plaque and the lumen. Plaque rupture included also fibrous cap disruption detected over a calcified plaque characterized by protruding calcification, superficial calcium, and the presence of substantive calcium proximal or distal to the lesion.\n\nThin cap fibro atheroma will be defined as cap thickness \\< 65 nm. Thin cap fibro atheroma at rupture site will be reported.\n\nFibrocalcific, fibrotic plaque, lipid component or macrophage infiltration will be defined according to the recent proposed criteria and reported.\n\nData will be divided according the clinical significance of the studied plaque, in particular culprit plaque, not culprit plaque in culprit vessel and not culprit plaque in other vessels.\n\nMoreover will be recoded if OCT analysis changed the interventional cardiologist approach in deciding the culprit lesion to treat.\n\nCLINICAL FOLLOW-UP AND ENDPOINT DEFINITION A clinical follow-up at least of 12 months after discharge will be evaluated.\n\nThe primary endpoint will be the correlation of OCT characteristics with incidence of major adverse cardiovascular events (MACEs defined as the composite of death from cardiac causes, non- fatal MI, clinically driven target vessel revascularization (TVR), or re-hospitalization due to unstable or progressive angina according to Braunwald Unstable Angina Classification) and clinical baseline characteristics.\n\nIn particular subanalysis will be performed in the following subgroups: culprit plaque, not culprit plaque in culprit vessel, not culprit plaque in different vessel.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'The OCT-FORMIDABLE register will include with a retrospective fashion all consecutive patients that perform OCT on culprit and not culprit plaque in any subset in patients with ACS.
