[Cardiogenic shock].

Abstract

Cardiogenic shock (CS) is an end-organ hypoperfusion associated with heart failure. Any reason impairing acute left ventricular (LV) or right ventricular (RV) function may cause CS. The only way to avoid CS is to provide early reperfusion in myocardial infarction (MI) patients. CS is characterized by permanent or transient rearrangement of the entire circulatory system. According to the current IABP-SHOCK II trial, 74% of the patients with CSMI are treated with norepinephrine, 53% of them with dobutamine, 26% of them with epinephrine, 4% of them with levosimendan, and 4% of them with dopamine. Percutaneous circulatory support devices such as intra-aortic balloon pump (IABP), LV assist device (LVAD), or extracorporeal life support (ECLS) create treatment options for selected patients such as CS, cardiopulmonary resuscitation, or high-risk pPCI and CABG. Extracorporeal Life Support Organization (ELSO, 2017) evaluated that the use of ECLS/VA-ECMO should be considered when the mortality risk exceeds 50% despite optimal conventional treatment in case of acute severe heart or pulmonary failure, whereas it should be assessed as a primary indication when it exceeds 80%. Early and effective revascularization is the best treatment option for CS. Thus, the organizations on the national and global basis will play the most effective role for the short- and long-term survival of patients.
