Development and verification of a nomogram risk prediction model for the incidence of IMR in STEMI patients hospitalized following PCI. A Nomogram predicting the risk of IMR during hospitalization in STEMI patients following PCI; (B) Model calibration curves predicting the risk of IMR during hospitalization; (C) Clinical impact curves of the model; (D) Model decision curve analysis; (E) ROC curves to evaluate the diagnostic performance of the model; (F) Comparison of the SII/100, LVEF, Gensini score, albumin and ROC curves of the nomogram risk prediction model. LVEF: Left ventricular ejection fraction; SII: Systemic immune-inflammation index
