Definite stent thrombosis is considered to have occurred by either angiographic or pathologic confirmation. Angiographic confirmation involves presence of a thrombus that originates in the stent or in the segment 5 mm proximal or distal to the stent and presence of at least 1 of the following criteria within 48-hours: Acute onset of ischemic symptoms at rest; New ischemic ECG changes that suggest acute ischemia; Typical rise and fall in cardiac biomarkers; Non-occlusive; Occlusive thrombus Evidence of recent thrombus within the stent determined at autopsy or via examination of tissue retrieved following thrombectomy is a pathological confirmation. Probable stent thrombosis is considered to have occur after intracoronary stenting in case of any unexplained death within the first 30 days or any MI that is related to documented acute ischemia in the territory of the implanted stent without angiographic confirmation of stent thrombosis and in the absence of any other obvious cause
