Key result
Diastolic wall shear stress is linked to BMI, smoking, and MI, differing from systolic stress.
Why the study?
It is unknown whether diastolic wall shear stress carries similar cardiovascular risk factors compared to systolic wall shear stress.

Observational diastolic wall shear stress associations should not change practice; hypothesis-generating for distinct cerebrovascular risk profiles.
Cross-Sectional (n=379)
Diastolic and systolic wall shear stress in the internal carotid artery are associated with distinct cardiovascular risk profiles, suggesting different pathophysiological roles.
Palm‐Meinders et al. (2009) conducted a cross-sectional in Atherosclerotic risk (n=379). Cardiovascular risk factors was evaluated on Diastolic and systolic wall shear stress in the internal carotid arteries. Diastolic wall shear stress was associated with BMI (p=0.04), smoking (p=0.05), and myocardial infarction (p<0.01), demonstrating a different risk factor profile than systolic wall shear stress.
