Abstract

Objective: This study describes the clinical, paraclinical characteristics, and treatment outcomes of patients with cardiogenic shock due to acute myocardial infarction. Subjects and Methods: This is a cross-sectional descriptive study conducted on 49 patients diagnosed with cardiogenic shock due to myocardial infarction at the Emergency and Intensive Care Department, Hanoi Medical University Hospital, from January 2022 to June 2024. Results: The average age of the patients was 76.1 ± 11.0 years, with a majority being male (59.2%). The average time from symptom onset to hospital admission was 15.1 ± 20.8 hours. Among the patients, 20.4% had symptoms of acute pulmonary edema upon admission, and 10.2% experienced pre-hospital cardiac arrest. Regarding paraclinical characteristics, 69.4% of patients had ST-segment elevation on electrocardiograms, and echocardiography showed a low left ventricular ejection fraction (EF = 36.2 ± 11.1%). During treatment, 33 out of 49 patients (67.3%) underwent emergency coronary intervention, 1 out of 49 patients (2.0%) received intra-aortic balloon pump support, and 4 out of 49 patients (8.2%) were treated with VA-ECMO. The in-hospital mortality rate was 63.5%. Conclusion: Cardiogenic shock patients showed a high rate of ST-segment elevation on electrocardiograms (69.4%) and had a low left ventricular ejection fraction (EF = 36.2 ± 11.1%) with multivessel coronary artery disease, particularly involving the left anterior descending artery. The in-hospital mortality rate was 65.3%.
