Correlation analyzes between each of apelinergic system components and biochemical diagnostic and prognostic markers of myocardial infarction (CRP, Hs-Troponin T, CK-MB, NT-proBNP) as well as echocardiographic (LVEF) were performed in order to clarify whether the ELA/AP/APJ receptor axis is implicated in vascular and myocardial dysfunction. This evidence concerns the gene CRP and myocardial infarction.
