Usefulness of albumin-to-D-dimer ratio in predicting the long-term outcome after hospital discharge in patients with ST-elevation myocardial infarction: a retrospective cohort study

Objective The Albumin-to-D-dimer ratio (ADR), a novel systemic inflammatory marker, has been linked to adverse outcomes in patients with cardiovascular disease. However, limited research has explored its prognostic value in ST-elevation myocardial infarction (STEMI) survivors following hospital discharge. This study aimed to evaluate the prognostic significance of ADR in hospital-discharged STEMI patients. Methods In this retrospective study, we analyzed data from 2,675 STEMI patients admitted to our hospital between January 2014 and December 2021. Patients were stratified into two groups based on their natural logarithmic ADR (Ln ADR): a high Ln ADR group (≥3.998) and a low Ln ADR group (
