Abstract:
Objective To examine the association of serum 25-hydroxyvitamin D levels with arterial stiffness and left ventricular hypertrophy (LVH) in elderly hypertension patients.Methods We recruited 166 elderly patients [mean age,(80.8 ± 6.2) years] with primary hypertension.Arterial stiffness was assessed by carotid femoral pulse wave velocity (cfPWV).Left ventricular mass index (LVMI) was determined according to the Devereux formula.Based on serum 25-hydroxyvitamin D levels,the patients were divided into two groups,the low 25-hydroxyvitamin D group (＜20 μg/L)and the high 25-hydroxyvitamin D group (≥20 μg/L).Results Faster cfPWV and larger LVMI values were observed in the low 25-hydroxyvitamin D group as compared with the high 25-hydroxyvitamin Dgroup [(15.00±3.04) m/s vs.(11.26±3.09) m/s;(120.14±25.82) g/m2 vs.(96.74±23.10) g/m2 ; t=-6.79,-5.16,respectively; both P=0.000].Multiple liner regression analysis showed that the 25-hydroxyvitamin D level was independently associated with LVMI (β=0.215,P=0.001) and cfPWV (β=-0.469,P＜0.001).Conclusions Serum 25-hyroxyvitamin D is independently associated with arterial stiffness,LVH Vitamin D may play an important role in the pathogenesis of arterial stiffness and LVH in elderly hypertension patients.
