TNFSF10 and ST Elevation Myocardial Infarction: The aim of the present study was to assess levels of both TRAIL and sFas in a homogenous group of patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI) in series of serum samples obtained during hospitalization and at one-month followup, to clarify the kinetics of serum levels of the two abovementioned apoptotic markers after STEMI.
