摘要: Atherosclerosis is the most serious and common form of cardiovascular disease in which plaque builds up inside arteries. Peak stress considered as main reason for rupture, results heart attack stroke. In current research, finite element method used to anticipate vulnerability, using human samples. A total 23 healthy atherosclerotic coronary arteries (14 9 atherosclerotic) were removed within 5 h postmortem. The samples mounted on a uniaxial tensile test machine obtained mechanical properties models. peak stresses Ogden hyperelastic model compared Mooney-Rivlin Neo-Hookean outcomes. indicated that hypocellular all three models has highest values cellular calcified ones and, result, quite prone rupture. type, contrast, lowest remains stable. can be vulnerability prediction have clinical implications interventions surgeries such balloon-angioplasty, cardiopulmonary bypass stenting.
