Subclinical cardiovascular disease and frailty risk: the atherosclerosis risk in communities study.

ABSTRACT:

Background

Cardiovascular disease (CVD) is associated with a greater frailty risk, but it remains unknown if pathways that contribute to CVD are associated with the frailty risk. Thus, we aimed to investigate whether elevations in high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) for those without known CVD at baseline are associated with a higher frailty risk.

Methods

This study used data from the Atherosclerosis Risk in Communities study. Cardiac biomarkers were measured from stored plasma samples collected at Visit 2 (1991-1993). Frailty was recorded at Visit 5 (2011-2013). Cox regression models were used to determine the association of cardiac biomarkers with frailty risk.

Results

Overall, 360/5199 (6.9%) participants aged 55.1 ± 5.1 years developed frailty during a median follow-up of 21.7 years. The incidence of frailty was significantly higher in participants with hs-cTnT ≥14 ng/L (vs. < 14 ng/L: 17.9% vs. 6.7%) or NT-proBNP ≥300 pg/ml (vs. < 300 pg/ml: 19.7% vs. 6.8%) (all P < 0.001). Comparing higher vs. lower cut-off levels of either hs-cTnT (14 ng/l) or NT-proBNP (300 pg/ml) demonstrated a greater than two-fold higher frailty risk, with hazard ratios (HRs) of 2.13 (95% confidence interval (CI): 1.130-4.01, P = 0.020) and 2.61 (95% CI: 1.28-5.33, P = 0.008), respectively. Individuals with both elevated hs-cTnT and NT-proBNP had a higher frailty risk than those without it (HR: 4.15; 95% CI: 1.50-11.48, P = 0.006).

Conclusions

High hs-cTnT and NT-proBNP levels are strongly associated with incident frailty in the community-dwelling population without known CVD. Subclinical cardiac damage (hs-cTnT) and/or wall strain (NT-proBNP) may be the key pathway of CVD patients developing frailty. Detection of hs-cTnT and NT-proBNP may help for early screening of high-risk frailty and providing individualised intervention.

Project description:Background/objectivesFalls are frequent and often devastating events among older adults. Cardiovascular disease (CVD) is associated with greater fall risk; however, it is unknown if pathways that contribute to CVD, such as subclinical myocardial damage or wall strain, are related to future falls. We hypothesized that elevations in high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), measured in older adults, would be associated with greater fall risk.DesignProspective cohort study.Setting and participantsAtherosclerosis Risk in Communities Study participants without known coronary heart disease, heart failure, or stroke.MeasurementsWe measured hs-cTnT or NT-proBNP in 2011 to 2013. Falls were identified from hospital discharge International Classification of Diseases, Ninth Revision (ICD-9), codes or Centers for Medicare and Medicaid Services claims. We used Poisson models adjusted for age, sex, and race/study center to quantify fall rates across approximate quartiles of hs-cTnT (less than 8, 8-10, 11-16, and 17 or greater ng/L) and NT-proBNP (less than 75, 75-124, 125-274, and 275 or greater pg/mL). We used Cox models to determine the association of cardiac markers with fall risk, adjusted for age, sex, race/center, and multiple fall risk factors.ResultsAmong 3973 participants (mean age = 76 ± 5 years, 62% women, 22% black), 457 had a subsequent fall during a median follow-up of 4.5 years. Incidence rates across quartiles of hs-cTnT and NT-proBNP were 17.1, 20.0, 26.2, and 36.4 per 1000 person-years and 12.8, 22.2, 28.7, and 48.4 per 1000 person-years, respectively. Comparing highest vs lowest quartiles of either hs-cTnT or NT-proBNP demonstrated a greater than two-fold higher fall risk, with hazard ratios of 2.17 (95% confidence interval {CI} = 1.60-2.95) and 2.34 (95% CI = 1.73-3.16), respectively. In a joint model, the relationships of hs-cTnT and NT-proBNP with falls were significant and independent.ConclusionSubclinical elevations of cardiac damage and wall strain were each associated with a higher fall risk in older adults. Further research is needed to determine whether interventions that lower hs-cTnT or NT-proBNP also lower fall risk. J Am Geriatr Soc 67:1795-1802, 2019.

Project description:ImportanceVitamin D deficiency has been associated with hypertension, diabetes mellitus, and incident stroke. Little is known about the association between vitamin D and subclinical cerebrovascular disease.ObjectiveTo examine the relationship of 25-hydroxyvitamin D (25[OH]D) levels with cerebrovascular abnormalities as assessed on brain magnetic resonance imaging (MRI) among participants of the Atherosclerosis Risk in Communities (ARIC) Brain MRI study.Design, setting, and participantsParticipants were white and black adults aged 55 to 72 years with no history of clinical stroke who underwent a cerebral MRI at ARIC visit 3 (n = 1622) and a second cerebral MRI approximately 10 years later (n = 888).ExposuresThe 25(OH)D level was measured by mass spectrometry at visit 3, with levels adjusted for calendar month and categorized using race-specific quartiles.Main outcomes and measuresThe cross-sectional and prospective associations of 25(OH)D levels with white matter hyperintensities (WMHs) and MRI-defined infarcts were investigated using multivariable regression models.ResultsThe mean age of the participants was 62 years, 59.6% were women, and 48.6% were black. Lower 25(OH)D levels were not significantly associated with WMH score of severity, prevalent high-grade WMH score (≥3), or prevalent infarcts in cross-sectional, multivariable-adjusted models (all P > .05). Similarly, no significant prospective associations were found for lower 25(OH)D levels with change in WMH volume, incident high WMH score (≥3), or incident infarcts on the follow-up MRI, which occurred approximately 10 years later.Conclusions and relevanceA single measure of 25(OH)D was not cross-sectionally associated with WMH grade or prevalent subclinical infarcts and was not prospectively associated with WMH progression or subclinical brain infarcts seen on serial cerebral MRIs obtained approximately 10 years apart. These findings do not support optimizing vitamin D levels for brain health.
