Calcaneal quantitative ultrasound is associated with all-cause and cardiovascular disease mortality independent of hip bone mineral density.

ABSTRACT: Osteoporosis has been linked with increased risk of cardiovascular disease previously. However, few studies have detailed bone and vascular information. In a prospective study of older women, we demonstrated heel quantitative ultrasound measures were associated with increased cardiovascular and all-cause mortality, independent of established cardiovascular risk factors.

Introduction

Osteoporosis and low bone mineral density (BMD) have been previously linked to cardiovascular disease (CVD) and mortality. Calcaneal quantitative ultrasound (QUS) is used to evaluate bone material properties, especially in older women. However, it is uncertain whether it is related to risk of mortality. This study was aimed to investigate the association between calcaneal QUS measurements and 15-year all-cause and CVD mortality in 1404 older women (mean age 75.2 ± 2.7 years).

Methods

One thousand four hundred four older women, participants of Calcium Intake Fracture Outcome study (CAIFOS), had calcaneal bone measured at baseline (1998) and followed for 15 years. The primary outcomes, any deaths, and deaths attributable to cardiovascular causes ascertained by using linked data were obtained from Western Australia data linkage system.

Results

Over the 15 years of follow-up (17,955 person years), 584 of the women died, and 223 from CVD. For every standard deviation (SD), reduction in broadband ultrasound attenuation (BUA) in minimally and multivariable-adjusted model including cardiovascular risk factors increased relative hazards for all-cause (multivariable-adjusted HR 1.15; 95%CI: 1.06-1.26, p = 0.001) and CVD mortality (multivariable-adjusted HR 1.20; 95%CI: 1.04-1.38, p = 0.010). Such relationships also persisted when hip BMD was included in the model (all-cause mortality HR 1.19; 95%CI: 1.07-1.33, p = 0.002; CVD mortality HR 1.28; 95%CI: 1.07-1.53, p = 0.008).

Conclusion

BUA is associated with all-cause and CVD mortality in older women independent of BMD and established CVD risk factors. Understanding why and how these are related may provide further insights about the bone-vascular nexus as well as therapeutic targets benefiting both systems.

Project description:BackgroundThe effect of pregnancy and breastfeeding on a female's bone mineral density (BMD) is controversial. This prospective study aims to investigate the effect of parity on BMD among pre-menopausal multiparous females using quantitative ultrasound as a screening method and females with no pregnancies (nulliparous) as a control group.MethodsA portable ultrasound-based bone densitometer (DMS PEGASUS SMART, Mauguio, France) was used to indirectly assess the BMD in 51 multiparous (29-45 years) and 51 nulliparous Arabic females (18-35 years) by quantifying the broadband ultrasound attenuation (BUA) from their right calcaneus bone. BUA > 70 db/mhz = normal, BUA 65-69.9 db/mhz = below average, BUA 55-64.9 db/mhz = osteopenia and BUA < 55 db/mhz = osteoporosis.ResultsThere was a significant difference in mean BUA between multiparous and nulliparous females (74.1 db/mhz vs. 69.3 db/mhz, p = 0.006). The prevalence of normal BMD was significantly higher in the nulliparous group than in the multiparous group (70.6% vs. 47.1%, p = 0.02). Osteoporosis was found in the multiparous group only (3/51). Among the multiparous females who breastfed (43/51), a total of 51.2% (22/43) had normal BMD, 25.6% (11/43) had BMD below average, 18.6% (8/43) had osteopenia and 4.7% (2/43) had osteoporosis. No significant differences in mean BUA (p = 0.2) were found between the group of females who breastfed for one year (13/43; BUA: 70.5 ± 9.4), the group of females who breastfed for 6-11 months (8/43; BUA: 70.6 ± 10.0) and those who breastfed for less than six months (22/43; BUA: 71.6 ± 9.4). A binary logistic regression model built for predicting BMD normality showed significance for the variable parity (p = 0.03), while the effect of the possible confounding variables BMI and age on BMD normality was found to be non- significant (p = 0.1 and p = 0.6, respectively).ConclusionParity affects the BMD, as assessed by a portable ultrasound-based bone densitometer, of young and middle-aged females as compared to the BMD of nulliparous females.

Project description:BackgroundCalcaneal quantitative ultrasound (QUS), which is used in the evaluation of osteoporosis, is believed to be intimately associated with the characteristics of the proximal femur. However, the specific associations of calcaneal QUS with characteristics of the hip sub-regions remain unclear.DesignA cross-sectional assessment of 53 osteoporotic patients was performed for the skeletal status of the heel and hip.MethodsWe prospectively enrolled 53 female osteoporotic patients with femoral fractures. Calcaneal QUS, dual energy X-ray absorptiometry (DXA), and hip structural analysis (HSA) were performed for each patient. Femoral heads were obtained during the surgery, and principal compressive trabeculae (PCT) were extracted by a three-dimensional printing technique-assisted method. Pearson's correlation between QUS measurement with DXA, HSA-derived parameters and Young's modulus were calculated in order to evaluate the specific association of QUS with the parameters for the hip sub-regions, including the femoral neck, trochanteric and Ward's areas, and the femoral shaft, respectively.ResultsSignificant correlations were found between estimated BMD (Est.BMD) and BMD of different sub-regions of proximal femur. However, the correlation coefficient of trochanteric area (r = 0.356, p = 0.009) was higher than that of the neck area (r = 0.297, p = 0.031) and total proximal femur (r = 0.291, p = 0.034). Furthermore, the quantitative ultrasound index (QUI) was significantly correlated with the HSA-derived parameters of the trochanteric area (r value: 0.315-0.356, all p<0.05) as well as with the Young's modulus of PCT from the femoral head (r = 0.589, p<0.001).ConclusionThe calcaneal bone had an intimate association with the trochanteric cancellous bone. To a certain extent, the parameters of the calcaneal QUS can reflect the characteristics of the trochanteric area of the proximal hip, although not specifically reflective of those of the femoral neck or shaft.

Project description:BackgroundHip fractures significantly reduce the quality of life and mobility of older adults. This study aimed to analyze the correlation between volumetric bone mineral density (vBMD) in different regions of the proximal femur as measured by quantitative computed tomography (QCT) and various subtypes of hip fractures.MethodsThis case-control study included patients over the age of 65 years admitted to Huadong Hospital Affiliated to Fudan University for hip fractures from November 2022 to December 2023; additionally, patients from the health examination center or outpatient center treated during the same period were included as a control group. Age and gender were matched to eliminate potential confounding factors. The vBMD at the femoral neck (FN), intertrochanteric (IT), and subtrochanteric (ST) regions in the hip fracture groups [FN fracture (FNF) and IT fracture (ITF)] and control group were measured using QCT.ResultsA total of 107 patients with FNF, 77 with ITF, and 72 controls were included. After matching for age and gender was completed, 48 individuals were included in each of the three groups. The vBMD at the IT, FN, and ST regions were significantly lower in patients with hip fractures compared to those in the control group for both genders (P<0.001). The vBMD of the FN and IT regions of females in the ITF group was lower than that of those in the FNF group (P<0.05). Additionally, the vBMD of the ST region in both genders was lower in the ITF group than in the FNF group (male: P<0.05; female: P<0.001). In all three groups, females had a significantly lower vBMD in all three regions compared to males (P<0.001). The decline in vBMD was more pronounced in the ITF group than in the FNF group for both genders, with the largest reduction compared to controls observed in the ST region of females in the ITF group.ConclusionsOlder adult individuals with a lower hip vBMD are more susceptible to experiencing osteoporotic hip fracture than are those with a normal vBMD. Reduced ST vBMD may serve as an indicator for ITF, especially among females.
