Abstract 86: Rates and Association of Risk Factors with Device Infection in Veterans Undergoing Cardioverter-Defibrillator Implantation Enrolled in the OVID Registry

Introduction: Implanted cardiac device infections are a source of significant morbidity, mortality, and cost. The rates and predictors of device infection among patients undergoing implantable cardioverter defibrillator (ICD) implantation in the VA population have not been previously described. Methods: Among veterans enrolled in the Outcomes among Veterans with Implantable Defibrillators (OVID) registry between 2003 and 2009, 3,918 were identified as within 3 months of initial ICD implantation. Baseline clinical characteristics and clinical outcomes were abstracted from the electronic medical record and social security death index. The rates of device infection were calculated per 100 person years and a priori specified predictors of device infection were examined for association with device infection using Cox proportional hazards regression. Results: Over 11,290 person years of follow up, only 76 device infections were identified for a rate of 0.67 per 100 person years (95% CI 0.54 to 0.84). Among these, 21 (27.6%) occurred within 30 days of implantation, 19 (25.0%) occurred 30 to 90 days after implantation, 8 (10.5%) occurred 90 days to 1 year after implantation, and 28 occurred greater than 1 year after implantation. The most common type of infection was a pocket infection and it was most likely to occur within 30 days of implantation. Of the examined a priori specified predictors (age, generator change, diabetes mellitus, warfarin use, chronic kidney disease and congestive heart failure), only generator change was statistically significantly associated with device infection when adjusted for comorbidities (adjusted HR 2.95; 95% CI 1.42 - 6.12). The rate of device infection among those with a generator change was 1.26 per 100 person years compared to 0.60 per 100 person years for those without a generator change. Conclusions: The overall rate of device infection in this population is lower than previously published rates and only generator change was associated with an increased risk of device infection.

Introduction: It is unknown whether hyponatremia is associated with risk of heart failure hospitalization or mortality among patients undergoing implantable cardioverter-defibrillator (ICD) implantation. This study was undertaken to assess whether or not hyponatremia is an independent risk factor for heart failure hospitalization or mortality following ICD implantation. Methods: The Outcomes among Veterans with Implantable Defibrillators (OVID) registry is a prospectively identified national cohort of VA patients who underwent ICD implantation between 2003 and 2009. There were 3,918 patients who were identified and having serum sodium measured at the time of implantation. Hyponatremia was the primary exposure and was defined by a serum sodium of less than 135 milliequivalents per liter (mEq/L). We assessed the association of hyponatremia with heart failure hospitalization and mortality using Cox proportional hazards regression adjusted for demographics, comorbidities, and type of device. Results: The mean serum sodium was 138.5 mEq/L and 579 patients (15.0%) had hyponatremia. Over a mean follow up time of 2.52 years, the rate of heart failure hospitalization was 14.1 per 100 person-years, and mortality was 9.6 per 100 person-years for subjects with hyponatremia at the time of implantation, compared to 10.0 per 100 person-years and 6.5 per 100 person-years, respectively, for those without hyponatremia. After multivariable analysis, hyponatremia at the time of implantation was associated with increased risk of both heart failure hospitalization (adjusted HR, 1.29; 95% CI, 1.06 - 1.57; P = 0.012) and mortality (adjusted HR, 1.31; 95% CI, 1.05 - 1.64; P = 0.016). Conclusions: Preoperative hyponatremia is associated with a modestly increased risk of both subsequent heart failure hospitalization and mortality among veterans undergoing ICD implantation. Further studies should assess whether hyponatremia at the time of ICD implantation is a modifiable risk factor that can be optimized or whether it is a representation of overall health status.

Our aim was to assess the association between a priori defined dietary patterns and incident depressive symptoms. We used data from The Maastricht Study, a population-based cohort study (n = 2646, mean (SD) age 59.9 (8.0) years, 49.5% women; 15,188 person-years of follow-up). Level of adherence to the Dutch Healthy Diet (DHD), Mediterranean Diet, and Dietary Approaches To Stop Hypertension (DASH) were derived from a validated Food Frequency Questionnaire. Depressive symptoms were assessed at baseline and annually over seven-year-follow-up (using the 9-item Patient Health Questionnaire). We used Cox proportional hazards regression analyses to assess the association between dietary patterns and depressive symptoms. One standard deviation (SD) higher adherence in the DHD and DASH was associated with a lower hazard ratio (HR) of depressive symptoms with HRs (95%CI) of 0.78 (0.69–0.89) and 0.87 (0.77–0.98), respectively, after adjustment for sociodemographic and cardiovascular risk factors. After further adjustment for lifestyle factors, the HR per one SD higher DHD was 0.83 (0.73–0.96), whereas adherence to Mediterranean and DASH diets was not associated with incident depressive symptoms. Higher adherence to the DHD lowered risk of incident depressive symptoms. Adherence to healthy diet could be an effective non-pharmacological preventive measure to reduce the incidence of depression.

Abstract Background Anemia is common in older adults and associated with greater morbidity and mortality. The causes of anemia in older adults have not been completely characterized. Although elevated circulating growth and differentiation factor 15 (GDF-15) has been associated with anemia in older adults, it is not known whether elevated GDF-15 predicts the development of anemia. Methods We examined the relationship between plasma GDF-15 concentrations at baseline in 708 non-anemic adults, aged 60 years and older, with incident anemia during 15 years of follow-up among participants in the Invecchiare in Chianti (InCHIANTI) Study. Results During follow-up, 179 (25.3%) participants developed anemia. The proportion of participants who developed anemia from the lowest to highest quartile of plasma GDF-15 was 12.9%, 20.1%, 21.2%, and 45.8%, respectively. Adults in the highest quartile of plasma GDF-15 had an increased risk of developing anemia (Hazards Ratio 1.15, 95% Confidence Interval 1.09, 1.21, P<.0001) compared to those in the lower three quartiles in a multivariable Cox proportional hazards model adjusting for age, sex, serum iron, soluble transferrin receptor, ferritin, vitamin B12, congestive heart failure, diabetes mellitus, and cancer. Conclusions Circulating GDF-15 is an independent predictor for the development of anemia in older adults.

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.

Abstract STUDY QUESTION What is the association of oral contraceptives (OCs) and tubal ligation (TL) with early natural menopause? SUMMARY ANSWER We did not observe an association of OC use with risk of early natural menopause; however, TL was associated with a modestly higher risk. WHAT IS KNOWN ALREADY OCs manipulate hormone levels, prevent ovulation, and may modify the rate of follicular atresia, while TL may disrupt the blood supply to the ovaries. These mechanisms may be associated with risk of early menopause, a condition associated with increased risk of cardiovascular disease and other adverse health outcomes. STUDY DESIGN, SIZE, DURATION We examined the association of OC use and TL with natural menopause before the age of 45 years in a population-based study within the prospective Nurses’ Health Study II (NHSII) cohort. Participants were followed from 1989 to 2017 and response rates were 85-90% for each cycle. PARTICIPANTS/MATERIALS, SETTING, METHODS Participants included 106 633 NHSII members who were premenopausal and aged 25-42 years at baseline. Use, duration and type of OC, and TL were measured at baseline and every 2 years. Menopause status and age were assessed every 2 years. Follow-up continued until early menopause, age 45 years, hysterectomy, oophorectomy, death, cancer diagnosis, or loss to follow-up. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% CIs adjusted for lifestyle, dietary, and reproductive factors. MAIN RESULTS AND THE ROLE OF CHANCE Over 1.6 million person-years, 2579 members of the analytic cohort experienced early natural menopause. In multivariable models, the duration, timing, and type of OC use were not associated with risk of early menopause. For example, compared with women who never used OCs, those reporting 120+ months of OC use had an HR for early menopause of 1.01 (95% CI, 0.87-1.17; P for trend=0.71). TL was associated with increased risk of early menopause (HR = 1.17, 95% CI, 1.06-1.28). LIMITATIONS, REASONS FOR CAUTION Our study population is homogenous with respect to race and ethnicity. Additional evaluation of these relations in more diverse populations is important. WIDER IMPLICATIONS OF THE FINDINGS To our knowledge, this is the largest study examining the association of OC use and TL with early natural menopause to date. While TL was associated with a modest higher risk of early menopause, our findings do not support any material hazard or benefit for the use of OCs. STUDY FUNDING/COMPETING INTEREST(S) The study was sponsored by UO1CA176726 and R01HD078517 from the National Institutes of Health and Department of Health and Human Services. The work was supported by the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development. The authors have no competing interests to report.

Background: Growing evidence documents the association between low health literacy and poorer health outcomes. However, less is known about the relationship between health literacy and outcomes among patients with heart failure (HF). We examined the association of health literacy with risk of hospitalization and mortality in patients with HF. Methods: Residents in an 11-county region in southeastern Minnesota with incident HF from 1/01/2013 to 3/31/2015 were identified using the International Classification of Diseases, Ninth Revision code 428 (n=3715) and prospectively surveyed to measure health literacy using established screening questions. A total of 1992 patients returned a survey (response rate 54%); 1779 patients with complete clinical data and adequate follow up were retained for analysis. Health literacy, measured as a composite on three 5-point scales, was categorized as adequate (≤ 10) or low (> 10). Cox proportional hazards regression and Andersen-Gill models were used to determine the association of health literacy with mortality and hospitalization. Results: Among 1779 patients (mean age 74, 53% male), 10% had low health literacy. After a mean follow-up of 8±4 months, 72 deaths and 600 hospitalizations occurred. Low health literacy was associated with increased mortality and hospitalizations (Figure). After adjusting for age, sex, comorbidity, education and marital status, the hazard ratio for death and hospitalization in patients with low health literacy was 2.84 (95% CI: 1.63, 4.96) and 1.43 (95% CI: 1.04, 1.96) respectively, compared to patients with adequate health literacy. Conclusions: Low health literacy is associated with increased risk of hospitalization and death among patients with HF. Health literacy is critical to the self-management demands of living with heart failure. Evaluation of health literacy in the clinical setting may guide inventions to target patients with low literacy.

Abstract Background Delirium is a distressing neurocognitive disorder recently linked to sleep disturbances. However, the longitudinal relationship between sleep and delirium remains unclear. This study assessed the associations of poor sleep burden, and its trajectory, with delirium risk during hospitalization. Methods 321,818 participants from the UK Biobank (mean age 58±8y[SD]; range 37-74y) reported (2006-2010) sleep traits (sleep duration, excessive daytime sleepiness, insomnia-type complaints, napping, and chronotype–a closely-related circadian measure for sleep timing), aggregated into a sleep burden score (0-9). New-onset delirium (n=4,775) was obtained from hospitalization records during 12y median follow-up. 42,291 (mean age 64±8; range 44-83y) had repeat sleep assessment on average 8y after their first. Results In the baseline cohort, Cox proportional hazards models showed that moderate (aggregate scores=4-5) and severe (scores=6-9) poor sleep burden groups were 18% (hazard ratio 1.18 [95% confidence interval 1.08-1.28], p<0.001) and 57% (1.57 [1.38-1.80], p<0.001), more likely to develop delirium respectively. The latter risk magnitude is equivalent to two additional cardiovascular risks. These findings appeared robust when restricted to postoperative delirium and after exclusion of underlying dementia. Higher sleep burden was also associated with delirium in the follow-up cohort. Worsening sleep burden (score increase ≥2 vs. no change) further increased the risk for delirium (1.79 [1.23-2.62], p=0.002) independent of their baseline sleep score and time-lag. The risk was highest in those under 65y at baseline (p for interaction <0.001). Conclusion Poor sleep burden and worsening trajectory were associated with increased risk for delirium; promotion of sleep health may be important for those at higher risk.

Evidence on the role of supper timing in the development of cardiovascular disease (CVD) is limited. In this study, we examined the associations between supper timing and risks of mortality from stroke, coronary heart disease (CHD), and total CVD. A total of 28,625 males and 43,213 females, aged 40 to 79 years, free from CVD and cancers at baseline were involved in this study. Participants were divided into three groups: the early supper group (before 8:00 p.m.), the irregular supper group (time irregular), and the late supper group (after 8:00 p.m.). Cox proportional hazards regression models were used to calculate hazard ratios (HRs) for stroke, CHD, and total CVD according to the supper time groups. During the 19-year follow-up, we identified 4706 deaths from total CVD. Compared with the early supper group, the multivariable HR of hemorrhagic stroke mortality for the irregular supper group was 1.44 (95% confidence interval [CI]: 1.05–1.97). There was no significant association between supper timing and the risk of mortality from other types of stroke, CHD, and CVD. We found that adopting an irregular supper timing compared with having dinner before 8:00 p.m. was associated with an increased risk of hemorrhagic stroke mortality.

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: 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.
