The cardiovascular system operates through complex hemodynamic processes involving pulsatile blood flow, varying viscosity, and the branching architecture of vessels. Interactions between blood flow and the vascular wall, which are characterized by s

Abstract Background Morphologically, the risk of aortic aneurysm rupture is mainly evaluated based on its type (e.g., fusiform or saccular) and diameter. Based on the finite element analysis, peak wall stress has been identified as a more sensitive a

Background: Acute ST-segment elevation myocardial infarction [STEMI] results in left ventricular adverse remodeling [LVR]. Increased left ventricular wall stress [LVWS] after Myocardial infarction [MI] initiates this process. Predicting the risk of f

Objective: Biomechanical modeling of infrarenal aortic aneurysms seeks to predict ruptures in advance, thereby reducing aneurysm-related deaths. As individual methods focusing on strain and stress analysis lack adequate discretization power, this stu
