Increased levels of plasma troponins and natriuretic peptides in the general population are associated with increased future risk of cardiovascular disease, but only limited information exists on these biomarkers and stroke occurrence. In a prospective epidemiological study, the Atherosclerosis Risk in Communities (ARIC) Study, we tested the hypothesis that high-sensitivity troponin T (TnT) and N-terminal pro B-type natriuretic peptide (NT-proBNP) are associated positively with incidence of stroke. We measured plasma high-sensitivity TnT and NT-proBNP in 10,902 men or women initially free of stroke and followed them for a mean of 11.3 years for stroke occurrence (n=507). Analyses were performed using proportional hazards modeling. Both biomarkers were associated positively with total stroke, nonlacunar ischemic, and especially, cardioembolic stroke, but not with lacunar or hemorrhagic stroke. After adjustment for other stroke risk factors, the hazard ratio (95% CI) per one SD greater increment of natural log-transformed TnT was 1.23 (1.13, 1.35) for total stroke, 1.27 (1.15, 1.40) for total ischemic stroke, and 1.36 (1.14, 1.62) for cardioembolic stroke. Likewise, the hazard ratio per one SD greater natural log-transformed NT-proBNP, was 1.37 (1.26, 1.49) for total stroke, 1.39 (1.27, 1.53) for total ischemic stroke, and 1.95 (1.67, 2.28) for cardioembolic stroke. The hazard ratios for jointly high values of TnT (≥0.013 ug/L) and NT-proBNP (≥155.2 pg/mL), versus neither biomarker high, were 2.70 (1.92, 3.79) for total stroke and 6.26 (3.40, 11.5) for cardioembolic stroke, and somewhat stronger for NT-proBNP than TnT. Strikingly, approximately 58% of cardioembolic strokes occurred in the highest quintile of pre-stroke NT-proBNP (versus 3% occurring in the lowest quintile), and 32% of cardioembolic strokes occurred in participants who had both NT-proBNP in the highest quintile and were known by ARIC to have atrial fibrillation sometime before their cardioembolic stroke occurrence. In conclusion, in the general population, elevated plasma TnT and NT-proBNP concentrations are associated with increased risk of cardioembolic and other nonlacunar ischemic strokes.

Introduction: Gum, or periodontal disease (PD) is a risk factor for cardiovascular disease. We assessed the graded association of PD levels with incident ischemic stroke as well as the etiological stroke subtypes in the Atherosclerosis Risk in Communities (ARIC) study. Methods: PD was assessed by full-mouth periodontal measurements from 6 sites per tooth, in subjects without prior stroke and categorized into periodontal profile class (PPC). A Latent Class Analysis was used to identify 7 distinct PPCs using the entire cohort that included tooth level periodontal measurements and tooth loss. Stroke diagnoses were based on computer derived diagnosis medical record review and imaging confirmation. Classification required evidence of sudden onset of neurological deficit(s) lasting ≥24 hours. Strokes were classified according to etiology as thrombotic, lacunar, and cardioembolic subtypes. Results: At the fourth ARIC visit (1996-1998), a cohort of 6711 subjects (mean age±SD=62.3±5.6, 55% female, 81% white and 19% African-American) were assessed for PD. A total of 299 incident ischemic strokes (47% thrombotic, 26% cardioembolic and 20% lacunar) occurred over a 15-year period. The seven levels of PPC showed a graded association with incident ischemic stroke as noted in the figure. Participants with mild PD (adjusted HR 1.9 95% CI 1.2-3.0), moderate PD group (adjusted HR 2.1 95% CI 1.2-3.5) and severe PD (adjusted HR 2.2 95% CI 1.3-3.8) had an increased risk of incident ischemic stroke, compared with participants without PD after adjustment for confounders (age, race, gender, BMI, hypertension, diabetes, LDL cholesterol, smoking and education). There were class specific associations noted between PD with cardioembolic and thrombotic stroke subtypes. Conclusions: A graded association was noted between incident ischemic stroke and increasing levels of PPC. Further, we report class specific associations between PD with cardioembolic and thrombotic stroke subtypes.

Background and Purpose Liver enzymes (aspartate aminotransferase [AST], alanine aminotransferase [ALT], and gamma-glutamyl transpeptidase [GGT]) are glutamate-regulatory enzymes, and higher glutamate levels correlated with worse prognosis of patients with neurotrauma. However, less is known about the association between liver enzymes and incidence of stroke. We evaluated the association between serum levels of AST, ALT, and GGT and incidence of stroke in the Atherosclerosis Risk in Communities (ARIC) study cohort from 1990 to 1992 through December 31, 2016.Methods We included 12,588 ARIC participants without prevalent stroke and with data on liver enzymes ALT, AST, and GGT at baseline. We used multivariable Cox regression models to examine the associations between liver enzymes levels at baseline and stroke risk (overall, ischemic stroke, and intracerebral hemorrhage [ICH]) through December 31, 2016, adjusting for potential confounders.Results During a median follow-up time of 24.2 years, we observed 1,012 incident strokes (922ischemic strokes and 90 ICH). In age, sex, and race-center adjusted models, the hazard ratios (HRs; 95% confidence intervals [CIs]) for the highest compared to lowest GGT quartile were 1.94 (95% CI, 1.64 to 2.30) for all incident stroke and 2.01 (95% CI, 1.68 to 2.41) for ischemic stroke, with the results supporting a dose-response association (P for linear trend <0.001). Levels of AST were associated with increased risk of ICH, but the association was significant only when comparing the third quartile with the lowest quartile (adjusted HR, 1.82; 95% CI, 1.06 to 3.13).Conclusions Elevated levels of GGT (within normal levels), independent of liver disease, are associated with higher risk of incident stroke overall and ischemic stroke, but not ICH.

ObjectiveVital exhaustion (VE), a construct defined as lack of energy, increased fatigue and irritability, and feelings of demoralisation, has been associated with cardiovascular events. We sought to examine the relation between VE and sudden cardiac death (SCD) in the Atherosclerosis Risk in Communities (ARIC) Study.MethodsThe ARIC Study is a predominately biracial cohort of men and women, aged 45–64 at baseline, initiated in 1987 through random sampling in four US communities. VE was measured using the Maastricht questionnaire between 1990 and 1992 among 13 923 individuals. Cox proportional hazards models were used to examine the hazard of out-of-hospital SCD across tertiles of VE scores.ResultsThrough 2012, 457 SCD cases, defined as a sudden pulseless condition presumed due to a ventricular tachyarrhythmia in a previously stable individual, were identified in ARIC by physician record review. Adjusting for age, sex and race/centre, participants in the highest VE tertile had an increased risk of SCD (HR 1.48, 95% CI 1.17 to 1.87), but these findings did not remain significant after adjustment for established cardiovascular disease risk factors (HR 0.94, 95% CI 0.73 to 1.20).ConclusionsAmong participants of the ARIC study, VE was not associated with an increased risk for SCD after adjustment for cardiovascular risk factors.
