The relationship between left ventricle (LV), extracellular matrix remodeling and fibrosis-linked amphiregulin (ARG) in cirrhotic cardiomyopathy (CCM) is unknown. The aim of the study was to investigate the associations between markers of extracellular matrix remodeling and ARG in cirrhosis and their association with indicators of ventricular remodeling and LV functional parameters. In hepatitis C virus (HCV) patients with cirrhosis, who underwent echocardiography, the presence of left ventricular diastolic dysfunction (LVDD) was determined by having gradable diastolic dysfunction in accordance with modified 2020 Cirrhotic Cardiomyopathy Consortium criteria. A total of 87 cirrhotic patients were consecutively analyzed. Based on detailed echocardiographic assessment - 35 HCV patients with cirrhosis had normal left ventricular diastolic function (non-CCM group), whereas 52 patients had LVDD (CCM group). ARG was measured by enzyme-linked immunosorbent assay. The ARG levels were significantly increased in the CCM group compared to the non-CCM group (P<0.001). ARG levels in all HCV patients were independently associated to the presence of CCM, and showed significant correlations with LVDD. The close relationship between ARG levels and the direct serum marker of fibrosis, and selected markers of extracellular matrix (i.e. transforming growth factor-beta1 (TGF-β1), and carboxyterminal propeptide of type I collagen (PICP), amino-terminal propeptide of type III procollagen (PIIINP), tissue inhibitor of matrix proteinase-1 (TIMP-1), respectively), ventricular remodeling (i.e. N-terminal pro B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin-T (hs-TnT)), and LV functional parameters suggest an active role in the myocardial injury. Using ROC analysis, the best marker for the diagnosis of CCM was NT-proBNP with AUROC = 0.796. The area under the curve of ARG (AUROC = 0.709) for predicting CCM was greater than this for PICP (AUROC = 0.662) and similar to this hs-TnT (AUROC = 0.753). The simultaneous monitoring of serum ARG and markers of extracellular matrix and ventricular remodeling can be helpful for the alterations in myocardial function control in HCV patients with cirrhosis.
