α-1 Antitrypsin as a potential biomarker in chronic heart failure

Background Heart failure is characterized by a tissue damage that progressively leads to mechanical cardiac dysfunction and remodeling. A recent investigation showed that α-1 antitripsin, an antiprotease, able to inhibit metalloproteinases, provides prognostic information about heart failure and mortality postacute myocardial infarction. Therefore, we conducted a study to establish if α-1 antitrypsin (AAT) could be considered a marker of...
