Abstract/OtherAbstract:
Extracellular matrix (ECM) in the heart and vascular wall includes fibrous proteins and proteoglycans. Fibrous proteins are classified within two categories: structural (collagen and elastin) and adhesive molecules (laminin and fibronectin). These ECM components are important in maintenance of both structure and function of the heart and vascular tissues. Myocardial infarction, hypertrophy, hypertension and heart failure are well known to be associated with progressive cardiac fibrosis. Vascular hypertrophy and thickening has been associated with the pathological series of events that attends both hypertension and restenosis. The accumulation of ECM in the cardiovascular system plays an important role in the development of heart failure after myocardial infarction and hypertension, as well as in vascular hypertrophy and restenosis. Angiotensin II (angiotensin) and transforming growth factor beta 1 are known to play a role in signalling the abnormal accumulation of ECM in these cardiovascular diseases. Administration of angiotensin-converting enzyme inhibitor or angiotensin receptor type 1 antagonist is associated with regression of cardiac hypertrophy and fibrosis as well as vascular hypertrophy.
