A number of factors are involved in congestive heart failure pathogenesis. Among these, inflammatory mediators could have a crucial role. Patients with congestive heart failure show increased plasma levels of "proinflammatory cytokines", in particular tumor necrosis factor-α and interleukin-6. Clinical and experimental models have demonstrated that these cytokines induce left ventricular dysfunction, pulmonary edema, ventricular remodeling, skeletal muscle abnormalities, myocyte apoptosis and endothelial dysfunction, suggesting the possibility that increased plasma concentration of cytokines could not be just an epiphenomenon, but an effective pathogenetic mechanism of disease progression. Additional inflammatory proteins involved in the acute phase response could play a part in the pathogenesis of heart failure. Pentraxin 3 is a prototypical long pentraxin, structurally related, although with different functions, to C-reactive protein, is produced by immune system cells, fibroblasts and particularly by cardiac endothelial cells and myocytes, as demonstrated in murine and human models. Its synthesis is rapidly induced after exposition to bacterial lipopolysaccharide and proinflammatory cytokines, as interleukin-1β and tumor necrosis factor-α. In heart diseases, pentraxin 3 could be involved in the acute local inflammatory response to myocardial injury (e.g. necrosis) and in heart failure pathogenetic mechanisms, but its exact role is not yet settled. Defining the specific part played by these molecules in the pathogenesis of heart failure could lead to new therapeutic approaches in the treatment of cardiac insufficiency.
