Key result
Load-dependent carotid stiffness is linked to ~38% higher incident CKD risk per m/s.
Why the study?
The relationship between arterial stiffness mechanisms—load-dependent stiffening versus structural stiffening—and end organ damage is unknown.
Are mechanisms of carotid artery stiffness (structural and load-dependent) associated with incident end-organ damage (CKD, dementia) and all-cause mortality?
Cohort (n=6,147)
Yes
Are mechanisms of carotid artery stiffness (structural and load-dependent) associated with incident end-organ damage (CKD, dementia) and all-cause mortality?
Hazard Ratio: 1.38 (95% CI 1.17–1.63)
p-value: p=<0.001
Differentiating arterial stiffness into structural and load-dependent components reveals distinct risk profiles, underscoring the importance of blood pressure control for preventing CKD and structural modification for reducing mortality.

May inform differential CKD versus mortality risk stratification; extends arterial stiffness research by separating load-dependent from structural components in observational data.
Pewowaruk et al. (2023) conducted a cohort in Healthy adults free of cardiovascular disease (n=6,147). Carotid artery stiffness mechanisms (load-dependent and structural) was evaluated on Incident chronic kidney disease (CKD) (HR 1.38 per 1 m/s, 95% CI 1.17-1.63, p=<0.001). Load-dependent carotid artery stiffness was significantly associated with incident chronic kidney disease (HR 1.38 per 1 m/s), whereas structural stiffness was associated with all-cause mortality.
