IntroductionThe main impact of myocardial infarction (MI) is shifting from acute mortality to adverse remodeling, chronic left ventricular (LV) dysfunction, and heart failure.ObjectivesThe aim of this study was to assess relationships between levels of circulating biomarkers and the function of LV after MI.Patients And MethodsThis was a prospective study of 80 patients with MI treated with percutaneous coronary intervention. Novel biomarkers including mid‑regional pro‑adrenomedullin (MR‑proADM), Notch‑1, syndecan‑4, myeloperoxidase, S‑100 protein, soluble ST‑2, as well as markers of inflammatory response and tissue injury: galectin‑3, C‑reactive protein (CRP), lactate dehydrogenase (LDH), and interleukin‑6 (IL‑6) were assessed in the acute phase of MI. Echocardiography was performed at baseline and 6 month Results: Adverse remodeling, defined as more than 20% increase in LV end‑diastolic volume, occurred in 26% of patients. Reverse remodeling (>10% reduction in LV end‑systolic volume) was observed in 52% of patients. In the univariable analysis, higher levels of MR‑proADM and LDH were predictors of adverse remodeling and higher levels of MR ‑proADM, LDH, CRP, and IL ‑6 were negative predictors of reverse remodeling. In the multivariable model, LDH remained an independent predictor of adverse remodeling (odds ratio [OR], 3.13; 95% CI, 1.42-8.18; P = 0.003) and a negative predictor of reverse remodeling (OR, 0.37; 95% CI, 0.17-0.8; P = 0.005).ConclusionsLDH and MR ‑proADM seem to be promising biomarkers of adverse remodeling. On the other hand, higher levels of these biomarkers were associated with reduced chance of occurrence of favorable reverse remodeling in MI patients. However, further studies on larger groups of patients are necessary to confirm these data.
