Patients with ST‐elevation myocardial infarction are at risk of developing cardiac arrest. A validated tool for predicting cardiac arrest would help physicians recognize these high‐risk patients earlier. This study assessed the usefulness of various score systems in predicting cardiac arrest in patients hospitalized for ST‐elevation myocardial infarction. Methods: Patients’ data were retrieved from the hospital's ST‐elevation myocardial infarction registry records. Patients aged 18 years or older seen at the emergency department with a diagnosis of ST‐elevation myocardial infarction between 1 July 2013 and 30 June 2014 were enrolled. The Thrombolysis in Myocardial Infarction score, the 6‐month Global Registry of Acute Coronary Event risk score, CHADS2 score, and HEART score were calculated and compared. Results: A total of 249 patients were recruited. The Thrombolysis in Myocardial Infarction score, 6‐month Global Registry of Acute Coronary Event risk score, CHADS2 score, and HEART scores were calculated. In total, 41 (16.5%) patients had cardiac arrest at emergency department or during hospitalization and 12 (29.3%) of them survived. The 6‐month Global Registry of Acute Coronary Event risk score had the biggest area under the receiver‐operating characteristic curve (0.72). Conclusion: The 6‐month Global Registry of Acute Coronary Event risk score is more useful in predicting cardiac arrest in patients hospitalized for ST‐elevation myocardial infarction than the other three scores. It is recommended that the 6‐month Global Registry of Acute Coronary Event risk score be calculated for identifying emergency department patients hospitalized for ST‐elevation myocardial infarction who are at risk of cardiac arrest during their hospital stay.
