ACUTE MYOCARDIAL INFARCTION, CARDIOGENIC SHOCK, DISEASES
Twenty-two patients with refractory cardiogenic shock who received VA-ECMO support in our centre were included in the study, including 13 males and 9 females aged 14 to 77 years. There were 11 cases of acute myocardial infarction, 8 cases of fulminant myocarditis and 3 cases of cardiac postoperative assistance.

There were no significant differences with regard to age, sex, basic diseases, APACHE II, ECMO running time, or mechanical ventilation support time between the two groups (all
