Abstract

Unlabelled: An inflammatory response plays a crucial role in myocardial damage after an acute myocardial infarction.

Objectives: To measure serum concentrations of several mediators in patients with an acute myocardial infarction (STEMI) and to assess their potential relationship with a risk of coronary instability.

Patients And Methods: The 33 patients with STEMI and 19 healthy volunteers were analyzed. The clinical data were obtained; as well serum concentrations of tryptase, endothelin (ET-1), angiogenin, soluble c-kit, and PDGF were measured.

Results: Patients with STEMI had higher serum tryptase and ET-1 than healthy volunteers (2,5 ± 0,4 ng/mL versus 1,1 ± 0,4 ng/mL and 0,7 ± 0,1 ng/mL versus 0,3 ± 0,1 ng/mL, resp.). Subjects with significant lesion in left anterior descending artery (LAD) had lower serum ET-1 compared to those with normal LAD (0,6 ± 0,2 pg/mL versus 0,9 ± 0,4 pg/mL). Patients with three-vessel coronary artery disease (CAD) had higher level of soluble c-kit compared to those with one- or two-vessel CAD: 19,9 ± 24,1 ng/mL versus 5,6 ± 1,9 ng/mL.

Conclusions: Elevated serum tryptase and ET-1 may be markers of increased coronary instability; some cytokines may be related to the extension of CAD.
