[Concentration of soluble Fas receptor (sFas) in serum of patients with ST-segment elevation myocardial infarction].

Introduction: Impairments ofapoptosis process, called programmed cell death, are the basis of pathogenesis of cardiovascular disease, including myocardial infarction. The aim of our study was to evaluated concentration of soluble receptor Fas (sFas)--marker ofapoptosis--in serum of patients with ST-segment elevation myocardial infarction.

Material And Methods: The study group consisted of 70 patients aged 42 to 75 (mean 58.
