Cardiogenic shock is characterized by inadequate tissue perfusion due to cardiac dysfunction, and it is often caused by acute myocardial infarction. The mortality rate in patients with cardiogenic shock is still very high (i.e., 50-60%). The pathophysiology of cardiogenic shock involves a vicious spiral circle: ischemia causes myocardial dysfunction, which in turn aggravates myocardial ischemia. ⋯ However, evidence for improved survival from randomized studies on the use of IABP in combination with PCI is lacking. (3) In order to achieve adequate perfusion, dobutamine and sometimes in combination with norepinephrine might be necessary. Recent studies have shown that the calcium sensitizer levosimendan in cardiogenic shock can be a useful addition to medical therapy. In this overview, epidemiology, pathophysiology, and guideline-oriented treatment strategies for cardiogenic shock are presented.
