Diabetics and non diabetics patients admitted for STEMI. In this population authors selected STEMI patients with multivessel (Mv) non obstructive coronary diseases (NOCS). These STEMI-Mv-NOCS had coronary lesions and stenosis <50%, with fractional flow reserve >0.8. In diabetics authors selected incretin users (6 months of incretin treatment before study enrollment) vs never-incretin-users diabetics.
