Key result
Simulated elevated blood pressure accelerates carotid plaque progression to ~32% stenosis over 5 years.
Why the study?
Understanding the initiation and progression of atherosclerosis related to elevated blood pressure is essential for proper diagnosis and management of cardiovascular disease.

Does elevated blood pressure increase wall shear stress and plaque progression in a 2-D idealized human carotid artery model?
Computational simulation demonstrates that elevated blood pressure increases wall shear stress and accelerates plaque progression in a carotid artery model.
Alagbe et al. (2022) studied Atherosclerosis. Elevated blood pressure (simulated) vs. Lower blood pressure (simulated) was evaluated on Plaque progression (stenosis severity). In a 2-D computational model of a human carotid artery, simulated elevated blood pressure (1500 Pa) accelerated plaque progression, resulting in 32.2% stenosis over 5 years compared to 2.95% at 0 Pa.
