Post Infarction Cardiogenic Shock: Is It Clinically Important to Differentiate Hemodynamic Patterns?

mtsAc , cArlos m. BArrero mtsAc Despite recent advances in the treatment of cardiogenic shock, it still remains the main cause of death in patients hospitalized for acute myocardial infarction. Although cardiogenic shock is classically described as a hemodynamic condition characterized by low cardiac output, increased filling pressure and elevated systemic vascular re- sistance, some patients present different patterns, as low systemic resistance, fever and leucocytosis, indicative of an important systemic inflammatory response. The clinical importance of having one hemodynamic pattern or the other is currently un- known, though the existence of two different hemodynamic patterns should lead to reconsider the support medical treatment in this severely ill group of patients. The aim of this work was to analyze the incidence of each type of cardiogenic shock (clas- sic and distributive), its clinical characteristics and its in-hospital outcome.
