A clear cause-and-effect relationship between excessive myocardial MMP-1 activity, increased mysial collagen degradation, and progression to systolic HF has been shown experimentally through the use of transgenic models and the use of pharmacological MMP activators.53,54 In addition, experimental evidence has been provided showing that following chronic neurohormonal activation, increased synthesis and release of MMPs into the local extracellular matrix of the cardiomyocyte occurs,55 which in turn could contribute to endomysial and perimysial collagen degradation and disruption.
