Finite element is used to analyze the effects of infarct on left ventricular end-diastolic function. The results for the symmetric infarct cases 1-6 demonstrated in this paper correspond to infarct percent by volume of 4, 8, 9, 16, 25 and 51% respectively. Using the developed three-dimensional model, these infarct percent by volume showed a reduction in end-diastolic volume (EDV) of 3, 5, 5, 8, 11, 17 mL respectively. Three natural infarct cases denoted A, B and C was evaluated consisting of 7%, 15% and 50% infarct region by volume respectively. The decrease in EDV for cases A, B and C were 6, 9 and 17 mL. The simulated decrease in EDV for the infarct cases was consistent with patients experiencing decreased tissue compliance. The higher left ventricle (LV) pressure resulted in an increase in wall stress opposite to the infarct for the symmetric and natural infarct cases.
