Computational model of left ventricle infarct remodelling during passive filling phase

Myocardial infarction causes part of the left ventricle muscle to not receive adequate oxygen supply and may cause muscle remodelling. Myocardium remodelling affects the blood pumping efficiency of the heart. In this paper, a model to describe myocardial remodelling during myocardial infarction is c...
