 The development of a number of regenerative strategies in recent years for "curing" heart disease represents a paradigm shift away from conventional approaches that aim to "manage" heart disease.Stem cell therapy can be used to help regenerate myocardium tissue and return the contractile function of the heart by creating/supporting a microenvironment before the MI.Developments in targeted drug delivery to tumors have provided the groundwork for the burgeoning field of targeted drug delivery to cardiac tissue.
