Despite significant advances in treating heart disease, heart failure remains a major cause of morbidity and mortality. Regardless of the initiating cause(s), heart failure is associated with disruptions in the myocardial extracellular matrix (ECM). ECM is a dynamic structure and its physiological turnover is mediated by matrix metalloproteinases (MMPs) and their inhibitors (TIMPs). Research in the past two decades has revealed that the function of ECM extends beyond its role in providing structural support. Similarly, ECM regulatory proteins, MMPs and TIMPs, have been demonstrated to play diverse and ECM‐independent roles in tissue remodeling and homeostasis. ECM is a network structure that in addition to providing structural support, serves as an extracellular reservoir for a number of growth factors and cytokines, and plays a central role in interstitial transport of different molecules (hormones, growth factors, drugs, etc.). This is mainly through the action of nonstructural ECM components, proteoglycans and matricellular proteins, which are also critical in cell‐ECM interactions and overall ECM remodeling. As such, sustaining the ECM integrity is not only critical in preserving cardiac geometry and function, it is essential in ensuring optimal delivery of different molecules to their site of action. Further, ECM composition and integrity in disease should be considered in designing drugs with a specific site of action. In this review article, we provide an overview of the ECM structure, components, its function in interstitial transport, heart disease‐dependent ECM remodeling, and the potential therapeutic approaches in preserving the diseased myocardial ECM and cardiac function. © 2015 American Physiological Society.
