Changes in the extracellular matrix during myocardial remodelling
Author(s): Markéta Hegarová*, Ivan Málek and Josef Kautzner
The present article focuses on the pathophysiology of myocardial extracellular matrix (ECM) remodelling in chronic heart failure (CHF). The trigger mechanisms for ECM remodelling include acute loss of contractile elements as a consequence of myocardial ischaemia, mechanical tension, oxidative stress and neurohumoral activation. The ECM phenotype changes as a result of the expression of fetal remodelling genes with the aim of accomplishing reparatory changes. This leads to a change in the composition of the ECM, rearrangement of the existing structures and an alteration of the proportion of individual components. While the ECM represents the target structure, at the same time, individual ECM components participate to various degrees directly in myocardial remodelling as modulators of a number of signalling pathways. Matricellular proteins are expressed in reaction to pathological stimu.. Read More»
