Research progress of percutaneous mechanical circulation support device in treatment of acute myocardial infarction complicated with cardiac shock

Currently, emergency percutaneous coronary intervention is becoming more and more accepted and standardized, new antiplatelet drugs are widely used, aortic balloon pump (IABP) is becoming more and more popular; however, the mortality of patients with acute myocardial infarction with cardiogenic shock is still high. Percutaneous mechanical circulatory support devices, including Impella, TendemHeart and ECMO, are expected to improve the prognosis of patients with cardiogenic shock by providing stronger hemodynamic support than IABP. Although the little clinical evidence available cannot fully demonstrate the clinical benefits of using percutaneous mechanical circulation support devices and the vascular and systemic complications cannot be ignored, percutaneous mechanical circulation support equipment is expected to be the key to successful treatment of myocardial infarction patients with cardiogenic shock with the technology development and increasing clinical experience.
