| Abstract [eng] |
The aim of this article is to review the recent literature on cardiogenic shock and circulatory support. This work reviews the clinical presentation and management of cardiogenic shock, focusing on the use of circulatory support in clinical practice and the benefits on survival. A literature review was performed using PubMed and Google Scholar systems, focusing on the literature of the last five years. Cardiogenic shock is a condition in which impaired cardiac output leads to life-threatening tissue hypoperfusion, which can lead to multiple organ dysfunction and death. It is mostly caused by acute coronary syndrome, but the number of cases of cardiogenic shock of other etiologies is also increasing. This paper presents various classifications to assess cardiogenic shock, reviews the epidemiology and explains the pathophysiology. The treatment of this disorder is directed towards the underlying disease. As the mortality rate of patients with cardiogenic shock remains high, the clinical application and survival benefit of circulatory support is assessed. The poor performance of the circulatory support devices is thought to be related to the inappropriate selection of patients for these treatments. The intra-aortic balloon pump remains the most used device, despite unfavourable outcomes in trials. Newer devices, while providing better haemodynamic performance and more time to decide on treatment tactics, do not show a significant improvement in survival compared to intra-aortic balloon pumps. |
