Key result
Crural medial arterial calcification linked to ~0.76 m/s higher cfPWV in T2D.
Why the study?
Animal studies suggest medial arterial calcification increases arterial stiffness leading to cardiovascular disease, but human studies are lacking.
Does peripheral medial and intimal arterial calcification pattern and quantity associate with central arterial stiffness in individuals with type 2 diabetes mellitus?
Population
774 individuals with type 2 diabetes mellitus
Comparison
Femoral and crural arterial calcification patterns (MAC, IAC, absent/indistinguishable) and calcification quantities
Design
Cross-sectional study

Does not support routine MAC screening in T2D; leaves open whether crural calcification predicts outcomes or warrants intervention.

Does peripheral medial and intimal arterial calcification pattern and quantity associate with central arterial stiffness in individuals with type 2 diabetes mellitus?
Effect estimate: Beta 0.76 m/s (95% CI 0.37-1.14)
Peripheral medial arterial calcification, particularly in the crural arteries, is independently associated with increased central arterial stiffness in patients with type 2 diabetes, suggesting a distinct mechanism for cardiovascular disease risk compared to intimal calcification.
Meer et al. (2025) conducted a cross-sectional in Type 2 diabetes mellitus (n=774). Peripheral medial and intimal arterial calcification vs. Zero calcification was evaluated on Carotid-femoral pulse wave velocity (cfPWV) (Beta 0.76 m/s, 95% CI 0.37-1.14). Crural medial arterial calcification was independently associated with increased arterial stiffness in type 2 diabetes, showing a higher pulse wave velocity (Beta 0.76 m/s; 95% CI 0.37-1.14).
