Osteoporosis is inversely associated with arterial stiffness in the elderly: An investigation using the Osteoporosis Self-assessment Tool for Asians index in an elderly Chinese cohort.

ABSTRACT: Although the association of arterial stiffness and osteoporosis has been reported, the relation of arterial stiffness with risk of osteoporosis and bone fracture is not established. The authors investigated the correlation between arterial stiffness (brachial-ankle pulse wave velocity [baPWV]), including a cutoff value, and risk of osteoporosis as assessed by the Osteoporosis Self-assessment Tool for Asia (OSTA) index in 129 elderly Chinese community-dwelling individuals (age 83.2 ± 12.8 years, 63 females). OSTA was negatively correlated with baPWV (r = -0.326, P = 0.023) after adjusting for confounding factors such as gender, body mass index, low-density lipoprotein, triglycerides, estimated glomerular filtration rate, absence or presence of diabetes, absence or presence of hypertension, and uric acid. baPWV was an independent factor for changes in OSTA (β = -0.001, P = 0.002). ROC curve analysis confirmed association between baPWV and OSTA index (AUC = 0.742 [CI: 0.660, 0.824]; P < 0.001) with a baPWV cutoff value of 1676 cm/s (sensitivity, 80.7%; specificity, 60%) for prediction of high OSTA index. The study showed a significant correlation between OSTA index and baPWV, suggesting a potential predictive value of baPWV in elderly patient at high risk of osteoporosis.

Project description:ImportanceRecent studies show that cerebral β-amyloid (Aβ) deposition is associated with blood pressure and measures of arterial stiffness in nondemented individuals.ObjectiveTo examine the association between measures of arterial stiffness and change in Aβ deposition over time.Design, setting, and participantsDeposition of Aβ was determined in a longitudinal observational study of aging by positron emission tomography using the Pittsburgh compound B twice 2 years apart in 81 nondemented individuals 83 years and older. Arterial stiffness was measured with a noninvasive and automated waveform analyzer at the time closest to the second positron emission tomography scan. All measures were performed under standardized conditions. Pulse wave velocity (PWV) was measured in the central (carotid-femoral and heart-femoral PWV), peripheral (femoral-ankle PWV), and mixed (brachial-ankle PWV) vascular beds.Main outcomes and measuresThe change in Aβ deposition over 2 years was calculated from the 81 individuals with repeat Aβ-positron emission tomography.ResultsThe proportion of Aβ-positive individuals increased from 48% at baseline to 75% at follow-up. Brachial-ankle PWV was significantly higher among Aβ-positive participants at baseline and follow-up. Femoral-ankle PWV was only higher among Aβ-positive participants at follow-up. Measures of central stiffness and blood pressure were not associated with Aβ status at baseline or follow-up, but central stiffness was associated with a change in Aβ deposition over time. Each standard deviation increase in central stiffness (carotid-femoral PWV, P = .001; heart-femoral PWV, P = .004) was linked with increases in Aβ deposition over 2 years.Conclusions and relevanceThis study showed that Aβ deposition increases with age in nondemented individuals and that arterial stiffness is strongly associated with the progressive deposition of Aβ in the brain, especially in this age group. The association between Aβ deposition changes over time and generalized arterial stiffness indicated a relationship between the severity of subclinical vascular disease and progressive cerebral Aβ deposition.

Project description:ObjectivesTo explore whether bone mineral density (BMD) is associated with arterial stiffness in middle-aged and elderly people with an advanced arterial stiffness index as indicated by the cardio-ankle vascular index (CAVI).DesignA cross-sectional study.SettingThis study was conducted from September 2015 to May 2017 at the geriatrics department of a provincial medical centre in China.ParticipantsA total of 580 patients aged 50 and over were enrolled in the study. The mean age of the group was 64.82±11.4 years, and 63.1% were male.Primary outcome measuresAssociations of age with CAVI values and BMD. Associations between BMD and CAVI values.ResultsWith increasing age, CAVI values gradually increased (p<0.001) and the femoral neck (FN) and total hip (TH) BMD gradually decreased (p<0.001, all). In the bivariate correlation analyses between the covariates and CAVI values, age and CAVI values showed the greatest positive correlation (r=0.631, p<0.001), and CAVI values were negatively correlated with FN BMD (r=-0.229, p<0.001) and TH BMD (r=-0.218, p<0.001). In the linear regression analyses, TH BMD (B=-1.812 (95% CI -2.475 to -1.149), p<0.001) and FN BMD (B=-1.968 (95% CI -2.651 to -1.284), p<0.001) were negatively correlated with CAVI values. After adjusting for age, gender, body mass index, smoking, history of cardiovascular or cerebrovascular disease, history of diabetes mellitus, systolic blood pressure, high-density lipoprotein cholesterol, blood uric acid, fibrinogen and estimated glomerular filtration rate, only TH BMD was still negatively correlated with CAVI values (B=-0.843 (95%CI -1.454 to -0.232), p=0.007). However, there was no consistent and significant correlation between lumbar spine BMD and CAVI values.ConclusionIn this cross-sectional study, a significant correlation between TH BMD and CAVI values was observed in middle-aged and elderly Chinese inpatients. However, our cohort was a small sample of inpatients, and prospective studies from more centres are expected.
