ROC curves of 5 different genes related to ferroptosis associated with myocardial infarction showed that SLC2A3, EPAS1, HMOX1, ATM and FANCD2 genes had good diagnostic value for myocardial infarction, and the elevation of SLC2A3, EPAS1 and HMOX1 was a risk factor for myocardial infarction. The gene discussed is ATM; the disease is myocardial infarction.
