OCT-Features in Culprit and Not Culprit Coronary Plaque in ACS Patients

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.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. In particular subanalysis will be performed in the following subgroups: culprit plaque, not culprit plaque in culprit vessel, not culprit plaque in different vessel. Secondary 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.
