Personalized Prediction of Left Ventricular Ejection Fraction in the Follow-Up of Patients with ST-Segment Elevation Myocardial Infarction: Development of a Practical Nomogram Model.

Baseline LVEF and peak CK-MB level were the strongest independent predictors of six-month LVEF following STEMI. Age, hypertension, and final TIMI flow grade were identified as additional predictors. The proposed nomogram provides a practical tool for individualized follow-up planning and risk assessment in STEMI survivors.
