Levels of cathepsins in acute myocardial infarction.

Aims/objective Over expression of matrix degrading enzymes have been implicated in plaque destabilisation and rupture. Cathepsins associated with extracellular matrix breakdown make them intriguing suspects. The aim of the study was to analyse peripheral levels of cathepsin B and cathepsin K and their inhibitor cystatin C during acute myocardial infarction (AMI).
