Abstract
In chronic congestive heart failure, an illness affecting more than 4 million Americans, there is impairment of myocardial extracellular matrix (ECM) remodeling. Failing human ventricular myocardium contains activated matrix metalloproteinases (MMPs), which are involved in adverse ECM remodeling. Our studies support the concept that impaired ECM remodeling and MMP activation are, in part, responsible for the cardiac structural deformation and heart failure. There is no known program that has declared its aim the investigation of the role of ECM gene therapy in heart failure. The development of transgenic technology, and emerging techniques for in vivo gene transfer, suggest a strategy for improving cardiac function by overexpressing or downregulation of the ECM components such as MMPs, tissue inhibitor of metalloproteinases (TIMPs), transforming growth factor-β1 (TGF-β), decorin, and collagen in cardiomyopathy and heart failure.
