    Evolving concepts in dilated cardiomyopathy.
    Eur J Heart Fail 2017 Dec 22. Epub 2017 Dec 22.
    Cardiovascular Department 'Ospedali Riuniti' and University of Trieste, Trieste, Italy.
    Dilated cardiomyopathy (DCM) represents a particular aetiology of systolic heart failure that frequently has a genetic background and usually affects young patients with few co-morbidities. The prognosis of DCM has improved substantially during the last decades due to more accurate aetiological characterization, the red-flag integrated approach to the disease, early diagnosis through systematic familial screening, and the concept of DCM as a dynamic disease requiring constant optimization of medical and non-pharmacological evidence-based treatments. However, some important issues in clinical management remain unresolved, including the role of cardiac magnetic resonance for diagnosis and risk categorization and the interaction between genotype and clinical phenotype, and arrhythmic risk stratification.

    The extracellular matrix (ECM) remodeling represents the pathological substrate of dilated cardiomyopathy (DCM). In this study, we statistically analyzed the immunoexpression of collagen I and III, matrix metalloproteinase-1 (MMP-1) and its tissue inhibitor-1 (TIMP-1) in the myocardial tissue in 18 cases of DCM compared to a control group. We observed a significant increase in the immunoexpression of collagen I and III in patients with DCM and a significant reduction in the immunoexpression of MMP-1 compared with the control group.
