<jats:title>Abstract</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>Progressive cardiac fibrosis is the central aspect of the myocardial involvement in systemic sclerosis (SSc). We hypothesized that circulating biomarkers of the cardiac fibrosis may be useful in the early diagnosis of the cardiac manifestation in this disease. Thus, we investigated the potential correlations between the levels of galectin-3, soluble suppression of tumorigenicity-2 (sST2) and the echocardiographic markers of the myocardial mechanics in SSc patients.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Forty patients (57.3 ± 13.7 years, 36 female) were investigated. In addition to the conventional echocardiography, tissue Doppler and speckle tracking-derived strain techniques were used to assess the function of both ventricles and atria. To estimate the correlations between galectin-3 and sST2 levels and the echocardiographic variables, partial correlation method was used with age as correcting factor.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>In age adjusted analysis galectin-3 level showed significant correlation with left ventricular global longitudinal strain (r = 0.460,<jats:italic>p</jats:italic> = 0.005); grade of left ventricular diastolic dysfunction (r = 0.394,<jats:italic>p</jats:italic> = 0.013); septal e’ (r = − 0.369,<jats:italic>p</jats:italic> = 0.021); septal E/e’ (r = 0.380,<jats:italic>p</jats:italic> = 0.017) and with the grade of mitral regurgitation (r = 0.323,<jats:italic>p</jats:italic> = 0.048). No significant correlation was found between sST2 levels and the echocardiographic variables.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Galectin-3 levels, but not sST2 levels show significant correlation with the parameters of the left ventricular systolic and diastolic function. Galectin-3 may be a useful biomarker for the screening and early diagnosis of SSc patients with cardiac involvement.</jats:p></jats:sec>
