Predictive value of serum iron on heart failure in patients with acute ST-segment elevation myocardial infarction

Abstract

Background: In clinical practice, heart failure often occurs after acute myocardial infarction, and a new biomarker for its early prediction is urgently needed. The aim of this study was to investigate the relationship between serum iron and heart failure after acute ST-segment elevation myocardial infarction (STEMI). Methods: A total of 41 patients with heart failure after STEMI and 31 controls were included in the study. The demographic variables and baseline clinical characteristics of both groups were analyzed. Results: There were no significant differences between patients with heart failure and controls in terms of demographic characteristics. There were significant differences in terms of serum iron, N terminal pro-B-type natriuretic peptide levels, left atrial diameter, and left ventricular ejection fraction. Binary logistic regression analyses demonstrated that serum iron (odds ratio [OR]: 0.804, 95% confidence interval [CI]: 0.699–0.924) and Tn-I (OR: 1.072, 95% CI: 1.011–1.137) were independent predictors for heart failure (p
