[Cardiogenic shock: from early diagnosis to multiparameter monitoring].

Cardiogenic shock (CS) is a life-threatening condition that occurs in response to reduced cardiac output, in the presence of adequate intravascular volume, and results in tissue hypoxia. CS can occur as a result of several etiologies but the most common is acute myocardial infarction. Despite the introduction of emergency revascularization for CS complicating acute myocardial infarction, mortality still remains exceptionally high, particularly in patients with refractory CS. The diagnosis of CS is sometimes challenging and it is based on clinical, hemodynamic, and biochemical signs. A multidisciplinary technical platform as well as specialized and experienced medical teams are crucial to treat this group of patients.We briefly summarize the main aspects of diagnosis, etiology and pathophysiology with a particular focus on macro- and microhemodynamic parameters that are essential for the diagnosis and treatment of this patient population.
