[Changes of Nonspecific Proteinases and Proinflammatory Cytokines in the Clinical Course of Acute Myocardial Infarction of Various Severity].
Kardiologiia 2018 March
PURPOSE: to study changes of serum levels of nonspecific proteinases, their inhibitors, and proinflammatory cytokines during short term observation of patients with acute myocardial infarction (MI).
MATERIALS AND METHODS: We included in this prospective short-term study 82 patients (27 with uncomplicated non-Q wave MI, 30 with Q-MI complicated by Killip class I-II acute left ventricular failure [ALVF], 17 with Q-MI complicated by Killip class III-IV ALVF, and 8 non-survivors due to development of cardiogenic shock) and 12 healthy controls. Serum levels of interleukin (IL) - 1β, IL-6 and tumor necrosis factor (TNF)-α were measured by ELISA. Elastaselike (ELA) and trypsin-like (TLA) activities as well as characteristics of proteinase inhibitors (antitrypsin activity and acid-stable inhibitors) were also determined. Blood samples were taken at hospital admission within 24 hours after onset of symptoms. The GUSTO Score at admission was used for risk stratification.
RESULTS: All cytokines levels were significantly elevated in MI patients in comparison to controls. Mean concentrations of IL-6 and TNF-α at baseline were higher among patients with MI complicated by ALVF than in the group with uncomplicated MI (27.45 vs 16.04 pikogram / mL, р.
