Arterial Stiffness Estimation by Shear Wave Elastography: Validation in Phantoms with Mechanical Testing
Elira Maksuti,Elira Maksuti,Erik Widman,Erik Widman,David Larsson,Matthew W. Urban,Matilda Larsson,Matilda Larsson,Anna Bjällmark,Anna Bjällmark +9 more
TL;DR: SWE by phase velocity analysis was validated to accurately measure stiffness in arterial phantoms, with a relative error between the two techniques of 8.8 ± 6.0% in the shear modulus range evaluated (40-100 kPa).

TL;DR: Allergic asthma is associated with distinct atherosclerotic artery changes compared to the respectively matched control collective, and the severity of asthma correlates with more pronounced pathological vessel alternations.

Quantification of carotid plaque elasticity and intraplaque neovascularization using contrast-enhanced ultrasound and image registration-based elastography
TL;DR: An ultrasound elastography technique based on registration of CEUS sequential images is developed and used for direct comparison between IPN and plaque elasticity and might be helpful for evaluation of carotid plaque vulnerability and for plaque risk stratification.

TL;DR: The term "vulnerable patient" may be more appropriate and is proposed now for the identification of subjects with high likelihood of developing cardiac events in the near future and a quantitative method for cumulative risk assessment of vulnerable patients needs to be developed.

Arterial Neovascularization and Inflammation in Vulnerable Patients Early and Late Signs of Symptomatic Atherosclerosis
Michael Fleiner,Marco Kummer,Martina Mirlacher,Guido Sauter,Gieri Cathomas,Reto Krapf,Barbara C. Biedermann +6 more
TL;DR: High intimal macrophage content and a hyperplastic network of vasa vasorum characterize vulnerable patients suffering from symptomatic atherosclerosis, and these changes are uniformly present in different arterial beds support the concept of symptomatic Atherosclerosis as a panarterial disease.
