Key result
Elderly carotid arteries exhibited significantly lower maximum longitudinal tensile stress (227.2 vs 254.8 kPa) and maximum strain compared to young carotid arteries (P < 0.05).

Cadaveric tensile tests may inform age-related carotid biomechanics; leaves open in vivo validation and clinical translation.
Objective: This study aimed to perform the carotid artery stretching experiments with young and elderly corpse for the study of carotid atherosclerosis pathogenesis and biomechanical basis. Methods: 15 carotid arteries were randomly selected from young and elderly groups, respectively, for the longitudinal tensile test, and 1 specimens of each group was randomly

Qin et al. (2015) conducted an observational in Carotid Atherosclerosis (n=40). Advanced age (Elderly) vs. Young age was evaluated on Maximum longitudinal tensile stress (kPa) (p=<0.05). Elderly carotid arteries exhibited significantly lower maximum longitudinal tensile stress (227.2 vs 254.8 kPa) and maximum strain compared to young carotid arteries (P < 0.05).
