Influences of gender, age, and body mass index on the arterial stiffness in hypertensive patients / 中国医师杂志

ABSTRACT

Objective To investigate the influences of gender,age,and body mass index (BMI)on the arterial stiffness in hypertensive patients.Methods A total of 1026 hypertensive patients were enrolled in this study from 6 community health centers in Baoshan District and Shanghai Third People's Hospital.The Related medical histories and carotid-femoral(C-F) pulse wave velocity (PWV) were recorded and PWV were re-tested in 672 patients after 1 year's follow-up.The C-F PWV was analyzed from different group of Gender,age and BMI at baseline and after follow up.Results (1)C-F PWV of the male hypertensive patients were higher than that of female's and the corresponding figures were (13.63 ±3.07)m/s and (12.59±2.85)m/s(P ＜0.01).After one year's follow up,C-F PWV was increased in both male and female with corresponding figures of (14.11 ± 3.58) m/s and (13.51 ± 3.56) m/s (P ＜ 0.05).(2) The C-F PWV was increased with age.The corresponding figures were [(11.11 ± 2.00) m/s for age group 30 ～ 50 years old,(12.73 ± 2.77) m/s for age group ＞ 50 ～ 70 years old,and (14.74 ± 3.29) m/s for age group ＞ 70 years old,all P ＜0.01].After one year's follow-up,C-F PWV of three age groups was increased and the corresponding figures were [(11.36±1.78)m/s(P ＞0.05),(13.39±3.33)m/s(P ＜0.01),and (15.68 ±3.94)m/s(P ＜0.05)].The increased range of C-F PWV (from high to low) was age group ＞ 70,age group ＞ 50 ～70 and age group 30 ～50.(3) C-F PWV of patients with BMI ≥ 24 kg/m2 was significantly lower than that of patients with BMI ＜24 kg/m2 and the corresponding figures were [(12.93 ±2.89)m/s and (13.39 ±3.18)m/s,P ＜0.05].After one year's follow up,C-F PWV was increased and the figures were [(13.54 ± 3.54) rn/s and (14.27±3.61) m/s,respectively(P ＜0.01)].Conclusions Except BMI,gender and age were the important influence factors on arterial stiffness.
