Endometrial cancer (EC) has been associated with an increased risk of cardiovascular disease, including atrial fibrillation (AF). We performed a prospective, case-controlled analysis among 310 Bulgarian women with new-onset, histologically confirmed EC, free of AF at the baseline survey, and women with normal (senile) endometrium/endometrial hyperplasia as a control group (n = 205). The risk of AF as well as relationship of adiponectin (APN) and high sensitivity C-reactive protein (hs-CRP) levels with AF in women with EC were calculated by Cox proportional hazards models. During the mean follow-up of 2.5 ± 0.5 years, new-onset AF had occurred in 11.7% of women with EC vs. 5.8% in the control group (p < 0.01). The risk of AF was highest in the first 6 months after new-onset EC, with an incidence rate ratio (IRR) of 1.19 (95% CI 1.10–1.29; p = 0.01). Women with EC, who were obese (body mass index (BMI) > 30 kg/m2) and younger (age < 60) were found to be more likely to develop AF (HR 1.95; 95% CI 1.18–3.32; p = 0.05). APN levels were not significantly associated with new-onset AF (95% CI 0.87–1.21; p = 0.063). However, the secondary analysis showed evidence of APN–AF association when adjusted for BMI (2.05; 95% CI 1.04–4.04; p = 0.037). We conclude that EC was significantly associated with the incidence of AF.

Introduction: In the Multicenter Automatic Defibrillator Implantation Trial-II (MADIT-II), the presence of atrial fibrillation (AF) at baseline was associated with an increased risk of death, and these patients received a substantial benefit from ICD therapy. In the current study, we evaluated the risk of death and the efficacy of ICD therapy in patients who developed new-onset AF after enrollment in the MADIT-II study. Methods/Results: Hazard ratios (HR) were determined using multivariate Cox proportional hazards method. Age ≥ 65 (HR 3.02, p < 0.01), QRS duration > 120 ms (HR 2.30, p < 0.01), and NYHA functional class ≥ 2 (HR 1.78, p = 0.03) were independent predictors of new-onset AF. In both treatment arms, there was a significant increase in the risk of death after developing new-onset AF (Post-AF) (n = 25 in conventional arm, n = 51 in ICD arm) than among patients before or without AF (Pre-AF) (n = 416 in conventional arm, n = 624 in ICD arm) as shown in the Mantel-Byar graphs. After adjusting for relevant covariates (including age, BUN, EF, and beta-blocker use), ICD therapy was associated with a greater reduction in the risk of death in patients who developed new-onset AF (HR 0.31, p = 0.013) compared to patients with no interim AF (HR 0.73, p = 0.055) [p = 0.085 for interaction between interim AF and ICD therapy]. Conclusions: The development of new-onset AF is associated with a significant increase in mortality and this group may be a target for closer follow-up and more aggressive treatment. ICD therapy was highly effective in reducing mortality in MADIT-II patients who developed new-onset AF after enrollment in the trial.

The aim of this study was to explore sex-specific associations between systolic blood pressure (SBP), hypertension, and the risk of incident atrial fibrillation (AF) subtypes, including paroxysmal, persistent, and permanent AF, in a general population. A total of 13,137 women and 11,667 men who participated in the fourth survey of the Tromsø Study (1994–1995) were followed up for incident AF until the end of 2016. Cox proportional hazards regression analysis was conducted using fractional polynomials for SBP to provide sex- and AF-subtype-specific hazard ratios (HRs) for SBP. An SBP of 120 mmHg was used as the reference. Models were adjusted for other cardiovascular risk factors. Over a mean follow-up of 17.6 ± 6.6 years, incident AF occurred in 914 (7.0%) women (501 with paroxysmal/persistent AF and 413 with permanent AF) and 1104 (9.5%) men (606 with paroxysmal/persistent AF and 498 with permanent AF). In women, an SBP of 180 mmHg was associated with an HR of 2.10 (95% confidence interval [CI] 1.60–2.76) for paroxysmal/persistent AF and an HR of 1.80 (95% CI 1.33–2.44) for permanent AF. In men, an SBP of 180 mmHg was associated with an HR of 1.90 (95% CI 1.46–2.46) for paroxysmal/persistent AF, while there was no association with the risk of permanent AF. In conclusion, increasing SBP was associated with an increased risk of both paroxysmal/persistent AF and permanent AF in women, but only paroxysmal/persistent AF in men. Our findings highlight the importance of sex-specific risk stratification and optimizing blood pressure management for the prevention of AF subtypes in clinical practice.

Gi Bleed

Background: Gastrointestinal (GI) bleeding is the most common type of major bleeding associated with oral anticoagulant (OAC) treatment. Patients with major bleeding are at an increased risk of a stroke if an OAC is not reinitiated. Methods: Non-valvular atrial fibrillation (NVAF) patients initiating OACs were identified from the Centers for Medicare and Medicaid Services ( CMS) Medicare data and four US commercial claims databases. Patients who had a major GI bleeding event (hospitalization with primary diagnosis of GI bleeding) while on an OAC were selected. A control cohort of patients without a major GI bleed during OAC treatment was matched to major GI bleeding patients using propensity scores. Stroke/systemic embolism (SE), major bleeding, and mortality (in the CMS population) were examined using Cox proportional hazards models with robust sandwich estimates. Results: A total of 15,888 patients with major GI bleeding and 833,052 patients without major GI bleeding were included in the study. Within 90 days of the major GI bleed, 58% of patients discontinued the initial OAC treatment. Patients with a major GI bleed had a higher risk of stroke/SE [hazard ratio (HR): 1.57, 95% confidence interval (CI): 1.42–1.74], major bleeding (HR: 2.79, 95% CI: 2.64–2.95), and all-cause mortality (HR: 1.29, 95% CI: 1.23–1.36) than patients without a major GI bleed. Conclusion: Patients with a major GI bleed on OAC had a high rate of OAC discontinuation and significantly higher risk of stroke/SE, major bleeding, and mortality after hospital discharge than those without. Effective management strategies are needed for patients with risk factors for major GI bleeding.

Research Questions

Objective: This study explored two research questions: (a) Does sleep medication neutralize or provide a protective effect against the hazard of Alzheimer’s disease (AD)? (b) Do apolipoprotein (APOE) e4 carriers reporting a sleep disturbance experience an increased risk of AD? Method: This study is a secondary analysis of the National Alzheimer’s Coordinating Center’s Uniform Data Set ( n = 6,782) using Cox proportional hazards regression. Results: Sleep disturbance was significantly associated with eventual AD development. Among the subset of participants taking general sleep medications, no relationship between sleep disturbance and eventual AD was observed. Among individuals not taking sleep medications, the increased hazard between the two variables remained. Among APOE e4 carriers, sleep disturbance and AD were significant, except among those taking zolpidem. Discussion: Our findings support the emerging link between sleep disturbance and AD. Our findings also suggest a continued need to elucidate the mechanisms that offer protective factors against AD development.

BACKGROUND: Aortic arch plaques (AAP) are a risk factor for cardiovascular embolic events. However, the risk of vascular events associated with AAP in the general population is unclear. AIM: To assess whether AAP detected by transesophageal echocardiography (TEE) are associated with an increased risk of vascular events in a stroke-free cohort. METHODS: The study cohort consisted of stroke-free subjects over age 50 from the Aortic Plaques and Risk of Ischemic Stroke (APRIS) study. AAP were assessed by multiplane TEE, and considered large if ≥ 4 mm in thickness. Vascular events including myocardial infarction, ischemic stroke and vascular death were recorded during the follow-up. The association between AAP and outcomes was assessed by univariate and multivariate Cox proportional hazards models. RESULTS: A group of 209 subjects was studied (mean age 67±9 years; 45% women; 14% whites, 30% blacks, 56% Hispanics). AAP of any size were present in 130 subjects (62%); large AAP in 50 (24%). Subjects with AAP were older (69±8 vs. 63±7 years), had higher systolic BP (146±21 vs.139±20 mmHg), were more often white (19% vs. 8%), smokers (20% vs. 9%) and more frequently had a history of coronary artery disease (26% vs. 14%) than those without AAP (all p<0.05). Lipid parameters, prevalence of atrial fibrillation and diabetes mellitus were not significantly different between the two groups. During the follow up (94±29 months) 30 events occurred (13 myocardial infarctions, 11 ischemic strokes, 6 vascular deaths). After adjustment for other risk factors, AAP of any size were not associated with an increased risk of combined vascular events (HR 1.07, 95% CI 0.44 to 2.56). The same result was observed for large AAP (HR 0.94, CI 0.34 to 2.64). Age (HR 1.05, CI 1.01 to 1.10), body mass index (HR 1.08, CI 1.01 to 1.15) and atrial fibrillation (HR 3.52, CI 1.07 to 11.61) showed independent association with vascular events. In a sub-analysis with ischemic stroke as outcome, neither AAP of any size nor large AAP were associated with an increased risk. CONCLUSIONS: In this cohort without prior stroke, the incidental detection of AAP was not associated with an increased risk of future vascular events. Associated co-factors may affect the AAP-related risk of vascular events reported in previous studies.

Background: Depression has been suggested as a potential risk factor for atrial fibrillation (AF) through effects on the autonomic nervous system and hypothalamus-pituitary-adrenal axis. Current literature examining the prospective relationship between depression and AF is inconsistent and limited to studies performed in predominantly white populations. We determined the relationship of both depressive symptoms and anti-depressant use with incident AF in a multi-ethnic cohort. Methods: The Multi-Ethnic Study of Atherosclerosis is a prospective study of 6,814 individuals without clinical cardiovascular disease. Depressive symptoms were assessed at baseline by the 20-item Center for Epidemiologic Studies Depression Scale (CES-D) and use of anti-depressant medications. Five CES-D groups were created based on the score distribution in approximate quartiles, and the top quartile split in 2 such that the top group represented persons with a score ≥16, a value commonly used to identify clinically relevant symptoms. Incident AF was identified from study ECGs verified for AF, ICD-9 hospital discharge diagnoses consistent with AF, and, for participants enrolled in fee-for-service Medicare, inpatient and outpatient AF claims data. Results: 6,644 participants (mean age=62; 53% women; 38% white; 28% black; 22% Hispanic; 12% Chinese-American) were included and followed for a median of 13 years. In separate adjusted Cox proportional hazards analyses, a CES-D≥16 (referent=CES-D<2) and anti-depressant use were each associated with higher incidence of AF (Table). Associations did not differ by race or gender (interaction p-values of 0.18 and 0.17 respectively). Similar results were obtained using time-updated measures of depression. Conclusions: Depressive symptoms are associated with an increased risk of incident AF. Further study into whether improving depressive symptoms reduces AF incidence is important.

Background: Increased blood pressure variability (BPV) has been associated with stroke risk, but never specifically in patients with diabetes. Methods: This is a secondary analysis of the Action to Control Cardiovascular Risk in Diabetes Follow-On Study (ACCORDION), the long term follow-up extension of ACCORD. Visit-to-visit BPV was analyzed using all BP readings during the first 36 months. The primary outcome was incident ischemic or hemorrhagic stroke after 36 months. Differences in mean BPV was tested with Student’s t-test. We fit Cox proportional hazards models to estimate the adjusted risk of stroke across lowest vs. highest quintile of BPV and report hazard ratios along with 95% confidence intervals (CI). Results: Our analysis included 9,241 patients, with a mean (SD) age of 62.7 (6.6) years and 61.7% were male. Mean (SD) follow-up was 5.7 (2.4) years and number of BP readings per patient was 12.0 (4.3). Systolic, but not diastolic, BPV was higher in patients who developed stroke (Table 1). The highest quintile of SBP SD was associated with increased risk of incident stroke, independent of mean blood pressure or other potential confounders. (Table 2, Figure 1). There was no interaction between SBP SD and treatment arm assignment, although the interaction for glucose approached significance (Table 2). Conclusion: Higher systolic BPV was associated with incident stroke in a large cohort of diabetic patients. Future trials of stroke prevention may benefit from interventions targeting BPV reduction.

Introduction: Growth differentiation factor 15 (GDF-15) is a marker of oxidative stress and inflammation and has been associated with several cardiovascular disease (CVD) phenotypes. However, conflicting results have been reported regarding the association of GDF-15 with incident atrial fibrillation (AF) in the general population. Hypotheses: Higher GDF-15 level is associated with increased risk of incident AF independent of potential confounders. Methods: In 10,101 White and Black ARIC participants (mean age 60 years and 20.9% Blacks) free of AF at baseline (1993-95), we quantified the association of GDF-15 and incident AF using three Cox proportional hazards models. GDF-15 was measured by SOMA scan assay. AF was defined by hospitalizations with AF diagnosis or death certificates (ICD-9 codes: 427.31-427.32; ICD-10 codes: I48.x) or AF diagnosis by ECG at subsequent ARIC visits. Results: There were 2165 cases of incident AF over a median follow-up of 20.7 years (incidence rate 12.1 cases/1,000 person-years). After adjusting for demographic characteristics and cardiovascular risk factors, log GDF-15 was significantly associated with incident AF (hazard ratio 1.42 (1.25-1.63) for top vs. bottom quartile) (Model 1 in Table ). The result was robust even further adjusting for history of other CVD phenotypes and cardiac markers (Models 2 and 3 in Table ). In Model 3, quartiles of high-sensitive cardiac troponin T (hs-cTnT) did not demonstrate significant associations with incident AF. Conclusions: In community-based population, elevated GDF-15 level was independently and robustly associated with incident AF (even more strongly than troponin). These results suggest the involvement of GDF-15 in the development of AF and the potential of GDF-15 as a risk marker to identify individuals at high risk of AF.

Background and Purpose: Diabetic retinopathy (DR) is a common microvascular complication of diabetes, which causes damage to the retina and may lead to rapid vision loss. Previous research has shown that the macrovascular complications of diabetes, including stroke, are often comorbid with DR. We sought to explore the association between DR and subsequent stroke events. Methods: This is a secondary analysis of patients enrolled in the ACCORD Eye study (Action to Control Cardiovascular Risk in Diabetes). The primary outcome was stroke during follow-up. The exposure was presence of DR at study baseline. We fit adjusted Cox proportional hazards models to provide hazard ratios for stroke and included interaction terms with the ACCORD randomization arms. Results: We included 2828 patients, in whom the primary outcome of stroke was met by 117 (4.1%) patients during a mean (SD) of 5.4 (1.8) years of follow-up. DR was present in 874 of 2828 (30.9%) patients at baseline and was more common in patients with than without incident stroke (41.0% versus 30.5%; P =0.016). In an adjusted Cox regression model, DR was independently associated with incident stroke (hazard ratio, 1.52 [95% CI, 1.05–2.20]; P =0.026). This association was not affected by randomization arm in the ACCORD glucose ( P =0.300), lipid ( P =0.660), or blood pressure interventions ( P =0.469). Conclusions: DR is associated with an increased risk of stroke, which suggests that the microvascular pathology inherent to DR has larger cerebrovascular implications. This association appears not to be mediated by serum glucose, lipid, and blood pressure interventions.

Objective Thyroid cancer (TC) survivors may be at risk of subsequent cardiovascular and cerebrovascular (CaV&CeV) morbidity. The 2009 American Thyroid Association (ATA) guidelines recommended less aggressive treatment for low-risk TC patients. The aim of this study was to assess the atherosclerotic CaV&CeV outcome of Israeli TC survivors compared to individuals with no thyroid disease, and the atherosclerotic CaV&CeV outcome before (2000–2008) and after (2009–2011) implementation of the 2009 ATA guidelines. Methods All members of the largest Israeli healthcare organization who were diagnosed with TC from 1/2000 to 12/2014 (study group) and age- and sex-matched members with no thyroid disease (controls) were included. Adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated using Cox proportional hazards models. Results The mean follow-up was 7.6 ± 4.2 and 7.8 ± 4.1 years for the study (n = 5,677, 79% women) and control (n = 23,962) groups, respectively. The former had an increased risk of new atherosclerotic CaV&CeV events (adjusted HR 1.26, 95% CI 1.15–1.39). The 5-year incidence of CaV&CeV was lower (adjusted HR 0.49, 95% CI 0.38–0.62) from 2009 to 2011 compared to 2000 to 2008, but remained higher in the study group than in the control group (adjusted HR 1.5, 95% CI 1.14–1.69). Conclusions This large Israeli population-based cohort study showed greater atherosclerotic CaV&CeV morbidity in TC survivors compared to individuals with no thyroid diseases. There was a trend toward a decreased 5-year incidence of atherosclerotic CaV&CeV events among TC survivors following the implementation of the 2009 ATA guidelines, but it remained higher compared to the general population.
