Brief summary
Reliability of 3D angio QFR functional evaluation of all non culprit lesions \>50% in STEMI patients during first acute procedure
Detailed description
3DAngio QFR is an angiographic based tool for coronary stenosis functional assessment: it is validated versus Adenosine FFR(ADOFFR) by several studies (FAVOR, VIRTU-1) ; in particular post contrast QFR (cQFR) showed a very good correlation with ADOFFR. Furthermore ADOFFR in non culprit vessel in acute stage of STEMI correlates well with ADOFFR of the same non culprit lesion in staged procedure. Aim of the study is to find a valid correlation between cQFR in acute study and ADOFFR in the staged procedure. A positive result may lead to a fast, easy and cost effective acute functional non culprit lesions evaluation during acute procedure for STEMI patients, selecting those,if any, to be treated immediately or in a staged procedure.
Interventions
The patient undergoes coronary angiography; if at least one stenosis from 40 to 90% in non culprit is present and FFR is indicated by guidelines the patient is enrolled to 3d Angio QFR evaluation; no adjunctive invasive procedures are needed for QFR measurements
