There are limited data regarding proper time of application and long-term clinical outcomes of extracorporeal membrane oxygenation (ECMO) in patient with cardiogenic shock (CS). This study appraised the clinical outcomes according to ECMO application or not and ECMO application time in the patients with acute myocardial infarction (AMI) combined CS.
From 2011 to 2015, a total of 13,081 patients with AMI were enrolled in a nation-wide AMI registry. Eligible patients with CS who underwent percutaneous coronary intervention (PCI) and had 3-year clinical follow-up, were analyzed. The study patients were divided into two groups: no ECMO application group (n = 887, 627 men, 67.8 ± 12.4 years) and ECMO application group (n = 112, 88 men, 62.8 ± 11.6 years). The ECMO application group was divided into two groups again: ECMO without cardiopulmonary resuscitation (CPR) group (n = 10, 7 men, 61.3 ± 13.4 years) and ECMO after CPR group (n = 102, 81 men, 62.9 ± 11.5 years).
So far, ECMO has been used as the last remedy for rescue and it has not been used frequently before patient’s condition got worse. In this study, ECMO before CPR showed good long-term clinical outcome. So early application of ECMO can be considered as a good procedure strategy in patients with CS with AMI.
