    Abstract: Introduction: Increasing evidence suggest that inflammation plays an important role in chronic disease progression in the elderly, a process known as inflammaging. We assessed the associations of interleukin-6 (IL-6) and interleukin-18 (IL-18) with global cardiovascular disease (CVD), atrial fibrillation (AF) and death among older adults. Methods: Participants from Atherosclerosis Risk in Communities study visit 5 (2011-2013; mean age 75.4±5.1 years) with measurements of IL-6 and IL-18 were included (N=5672). Enzyme-linked immunosorbent assay was used to quantify IL-6 and IL-18. The associations of IL-6 and IL-18 (modeled continuously and categorically as tertiles) with coronary heart disease (CHD), ischemic stroke, heart failure (HF), global CVD (composite of CHD, stroke, and HF), AF, and all-cause death were assessed using Cox regression analyses. Results: Over a median follow-up of 7.2 years, 1235 global CVD events, 530 AF events and 1173 deaths occurred. Higher IL-6 and IL-18 levels were both associated with global CVD after adjustment for cardiovascular risk factors. The association between IL-6 and CVD remained significant after further adjustment for IL-18, while the association between IL-18 and CVD was no longer significant after adjustment for IL-6. IL-6 but not IL-18 was also associated with increased risk for CHD, HF, and AF after adjustments for cardiovascular risk factors and each other. Both IL-6 and IL-18 were associated with increased risk for all-cause death (Table). In categorical analysis, the top tertile of IL-6 was associated with increased risk for global CVD, AF and death using the lowest tertile as the reference group. Conclusion: Among older adults, both IL-6 and IL-18 were associated with global CVD and death. However, the association of IL-18 with CVD appears to be mediated by IL-6.

    Abstract: Lower dehydroepiandrosterone-sulfate (DHEA-S) levels have been inconsistently associated with coronary heart disease (CHD) and mortality. Data are limited for heart failure (HF) and association between DHEA-S change and events. Objective Assess associations between low DHEA-S/DHEA-S change and incident HF hospitalization, CHD, and mortality in older adults. Design DHEA-S was measured in stored plasma from visits 4 (1996-1998) and 5 (2011-2013) of the Atherosclerosis Risk in Communities study. Follow-up for incident events: 18 years for DHEA-S level; 5.5 years for DHEA-S change. Setting General community. Participants Individuals without prevalent cardiovascular disease (n = 8143, mean age 63 years). Main Outcome Measure Associations between DHEA-S and incident HF hospitalization, CHD, or mortality; associations between 15-year change in DHEA-S (n = 3706) and cardiovascular events. Results DHEA-S below the 15th sex-specific percentile of the study population (men: 55.4 µg/dL; women: 27.4 µg/dL) was associated with increased HF hospitalization (men: hazard ratio [HR] 1.30, 95% confidence interval [CI] , 1.07-1.58; women: HR 1.42, 95% CI, 1.13-1.79); DHEA-S below the 25th sex-specific percentile (men: 70.0 µg/dL; women: 37.1 µg/dL) was associated with increased death (men: HR 1.12, 95% CI, 1.01-1.25; women: HR 1.19, 95% CI, 1.03-1.37). In men, but not women, greater percentage decrease in DHEA-S was associated with increased HF hospitalization (HR 1.94, 95% CI, 1.11-3.39). Low DHEA-S and change in DHEA-S were not associated with incident CHD. Conclusions Low DHEA-S is associated with increased risk for HF and mortality but not CHD. Further investigation is warranted to evaluate mechanisms underlying these associations.

    Abstract: Interleukin-6 (IL-6) and interleukin-18 (IL-18), important cytokines implicated in atherosclerosis and inflammaging, were assessed for associations with global cardiovascular disease (CVD), atrial fibrillation (AF), and death in older adults. Methods and results Participants from Atherosclerosis Risk in Communities study Visit 5 (mean age 75.4 ± 5.1 years) with IL-6 and IL-18 measurements were included (n = 5672). Cox regression models were used to assess associations of IL-6 and IL-18 with coronary heart disease (CHD), ischaemic stroke, heart failure (HF) hospitalization, global CVD (composite of CHD, stroke, and HF), AF, and all-cause death. Over a median follow-up of 7.2 years, there were 1235 global CVD events, 530 AF events, and 1173 deaths. Higher IL-6 [hazard ratio (HR) 1.57, 95% confidence interval (CI) 1.44–1.72 per log unit increase] and IL-18 (HR 1.13, 95% CI 1.01–1.26) were significantly associated with global CVD after adjustment for cardiovascular risk factors. Association between IL-6 and global CVD remained significant after further adjustment for high-sensitivity C-reactive protein (hs-CRP), N-terminal pro–B-type natriuretic peptide (NT-proBNP), and high-sensitivity troponin T (hs-TnT) but was no longer significant for IL-18 after further adjustments. Interleukin-6 was also associated with increased risk for CHD, HF, and AF after adjustment for covariates. Both IL-6 and IL-18 were associated with increased risk for all-cause death independent of cardiovascular risk factors and other biomarkers. Conclusion Among older adults, both IL-6 and IL-18 were associated with global CVD and death. The association between IL-6 with CVD appears to be more robust and was independent of hs-CRP, NT-proBNP, and hs-TnT.

    Abstract: Introduction: Membrane-bound angiotensin-converting enzyme 2 (ACE2) has been identified to a have prominent role in SARS-COV-2 infection and is an important counter-regulator of renin-angiotensin system. But the association of cleaved soluble ACE2 (sACE2) with cardiovascular disease (CVD) remains unclear. We sought to identify the association of sACE2 with cardiac biomarkers, structure, function and events in the Atherosclerosis Risk in Communities (ARIC) Study. Methods: sACE2 was measured in a subset of 497 patients from a case-control study of incident heart failure (HF) at visit 5 (2011-2013), mean age 78 (SD 5.4), 53% men and 27% black. We used linear regression to evaluate the associations of sACE2 with cardiac biomarkers (hs-cTnI, hs-cTnT, NT-proBNP) and echocardiographic parameters. We used Cox regression to evaluate associations of sACE2 with risk of HF hospitalization, global CVD events (CHD, ischemic stroke or HF hospitalization) and all-cause death. Results: Over a median follow up of 6.1 (4.6, 6.8) years, 282 global CVD events and 190 all-cause deaths occurred. sACE2 levels were higher in men, blacks, those with prevalent CVD, diabetes and hypertension. Higher sACE2 levels were associated with significantly higher hs-cTnI, hs-cTnT, NT-proBNP levels, greater left ventricular (LV) mass index, impaired diastolic function ( Table ) and increased risk for HF hospitalization (adjusted HR 1.32 per log unit increase, 95% CI 1.10-1.58), global CVD events (HR 1.34, 95% CI 1.13-1.60) and all-cause death (HR 1.26, 95% CI 1.01-1.57). Conclusions: In an elderly biracial cohort, sACE2 was positively associated with biomarkers reflecting myocardial injury and neurohormonal activation, LV mass index, impaired diastolic function, CVD events and all-cause death. Future research is needed to elucidate the significance of sACE2 in development of CVD, not only in patients with SAR—COV2 infection, but the general population
