Abstract: To summarize emergency care experience of 10 patients with acute ST-segment elevation myocardial infarction complicated by sudden cardiac arrest who underwent extracorporeal cardiopulmonary resuscitation combined with the emergency percutaneous coronary intervention. In view of the characteristics such as the rapid progression of the disease,the difficulty of establishing extracorporeal membrane oxygenation in the case of sudden cardiac arrest,the high risk of percutaneous coronary intervention,the poor postoperative recovery of nervous system function,and the instability of circulation,the caring measures were adopted,including the establishment of a multidisciplinary collaborative emergency care team,precise implementation of cardiopulmonary resuscitation,cooperation with doctors for rapid implementation of extracorporeal membrane oxygenation and percutaneous coronary intervention,temperature management and neurological function monitoring,stabilization of patient hemodynamics after extracorporeal cardiopulmonary resuscitation. Among the 10 patients,five patients' conditions were improved and were discharged,three patients were discharged after giving up treatment due to neurological dysfunction and/or combined multiple organ failure,one patient was transferred to a higher-level hospital for heart transplantation,and one patient died.
