Abstract
Cardiogenic shock (CS) is the leading cause of death in patients with acute myocardial infarction (MI) and we badly need new approaches in its treatment. It has been demonstrated that a number of inflammatory cytokines (IL-1β, IL-6, IL-8, TNF-α, CRP, soluble adhesion molecules, complement system etc) are elevated in acute MI complicated by CS. Baseline levels of pro- inflammatory cytokines have predictive value for the development of CS and subsequent mortality. The deleterious effects of pro- inflammatory cytokines may be due to excessive nitric oxide production by enzyme named NOS. However in multicenter randomized TRIUMPH study non-selective NOS inhibition was ineffective in the treatment of cardiogenic shock. A challenging subject of future studies will be treatment of CS with specific inhibitors of inducible isoform of NOS. Considering the results of treatment of patients with septic shock it would be reasonable to study the effects of small doses of corticosteroids and hemofiltration in patients with CS and signs of SIRS.
