Effects of Extracorporeal Membrane Oxygenation Combined with Emergency PCI in Resuscitating Acute Myocardial Infarction-Related Cardiac Arrest

Abstract

Objective:To analyze resuscitation strategies for cardiac arrest following acute myocardial infarction, focusing on the treatment effects of extracorporeal membrane oxygenation (ECMO) combined with emergency percutaneous coronary intervention (PCI). Methods: From January 2023 to June 2024, 100 cases of cardiac arrest following acute myocardial infarction were included and randomly divided into two groups: the control group (50 cases) received conventional cardiopulmonary resuscitation (CPR) combined with emergency PCI, while the observation group (50 cases) received ECMO combined with emergency PCI. The resuscitation effects, return of spontaneous circulation (ROSC) rate, Glasgow Coma Scale (GCS) score, vital signs, and complication rates were compared between the two groups. Results: The observation group had a survival rate of 90.00% and ROSC rate of 94.00%, which were higher than the control group's 70.00% and 76.00% (P < 0.05). The GCS scores on postoperative days 1, 2, and 3 were higher in the observation group (P < 0.05). The heart rate on postoperative days 1, 2, and 3 was lower in the observation group (P < 0.05), while the mean arterial pressure was higher (P < 0.05). The complication rate was lower in the observation group (P < 0.05). Conclusion: The combination of ECMO and emergency PCI for cardiac arrest following acute myocardial infarction significantly improves survival rates and ROSC rates, enhances consciousness levels and vital signs, and reduces complications.
