Background Decreased appetite can contribute to malnutrition in patients with heart failure (HF). Little is known about the trajectory of appetite over time in patients with HF and the factors associated with decreased appetite after discharge from the hospital.Objective The aims of this study were to investigate changes in appetite over time and explore how fatigue, depressive symptoms, and quality of life are associated with decreased appetite.Methods Data from the multicenter randomized Coordinating study evaluating Outcomes of Advising and Counseling in Heart Failure were used. Logistic regression and mixed-effects logistic regression were used to investigate changes in appetite over time and to explore the relationship between appetite and fatigue, depressive symptoms, and quality of life.Results A total of 734 patients with HF (mean age, 69 years) were included. Decreased appetite was present at all follow-up measurements; however, decreased appetite was significantly lower at the 1-month (odds ratio [OR], 0.43; confidence interval [CI], 0.29–0.63), 6-month (OR, 0.31; CI, 0.20–0.47), 12-month (OR, 0.22; CI, 0.14–0.34), and 18-month (OR, 0.24; CI, 0.15–0.37) follow-ups compared with baseline. Decreased appetite was associated with fatigue (OR, 3.09; CI, 1.98–4.84), depressive symptoms (OR, 1.76; CI, 1.35–2.29), and low quality of life (OR, 1.01; CI, 1.01–1.02) across all measurement points adjusted for covariates.Conclusions Appetite improved after discharge; however, at all time points, at least 22% of patients reported decreased appetite. Fatigue, depressive symptoms, and low quality of life are factors associated with decreased appetite. Decreased appetite is a long-standing problem in that it does not disappear spontaneously after an acute HF deterioration.
Background The Nutritional Risk Screening 2002 (NRS-2002) scale is a rapid and effective screening instrument that assesses nutritional risk among hospitalized patients.Objective The present study aimed to explore the prognostic value of the NRS-2002 scale in acute myocardial infarction (AMI) considering its uncertain role in this particular condition.Methods Patients with AMI included in the Retrospective Multicenter Study for Early Evaluation of Acute Chest Pain were investigated. Kaplan-Meier survival analysis and Cox proportional hazards models were used to analyze the association between NRS-2002 and mortality in patients with AMI. The primary and secondary endpoints were all-cause and cardiac mortality during the follow-up period.Results A total of 2307 patients were enrolled, among whom 246 (10.7%) died within a median follow-up duration of 10.67 (8.04–14.33) months. Kaplan-Meier analysis revealed that patients with an NRS-2002 score of 3 or higher had poorer cumulative survival than those with an NRS-2002 score lower than 3 (P < .001). In the multivariate Cox regression analysis, patients with an NRS-2002 score of 3 or higher had more than double the risk for all-cause mortality (hazard ratio, 2.25; 95% confidence interval, 1.50–3.40; P < .001) and twice the risk for cardiac-related mortality (hazard ratio, 2.01; 95% confidence interval, 1.29–3.13; P = .002) than did patients with lower scores.Conclusions Our results showed that the NRS-2002 screening instrument was an independent prognostic predictor for both all-cause and cardiac mortality in patients with AMI. Nutritional risk assessment based on the NRS-2002 scale may provide useful prognostic information of early nutritional risk stratification in patients with AMI.
Background Slow gait, frailty, insufficient postoperative caloric intake, and delirium, although seemingly distinct, can appear simultaneously in patients who underwent cardiac surgery.Objectives The aim of this study was to evaluate how these 4 factors overlap and how they individually and cumulatively affect cardiac surgery outcomes.Methods The effects of slowness (gait speed
Background Possible sarcopenia, aortic valve stenosis, and malnutrition are important issues that afflict older adults.Objective The aims of this study were to compare the differences in nutritional status and family support in older adults with possible sarcopenia and those without sarcopenia after undergoing transcatheter aortic valve implantation (TAVI) and to identify the predictors of malnutrition and demonstrate changes in heart function over time after undergoing TAVI.Methods A case-control design was conducted. Possible sarcopenia was identified by measuring calf circumference, grip strength, and gait speed. The Mini Nutritional Assessment-Short Form and numerical family support rating scale were used to collect data. Left ventricular ejection fraction and New York Heart Association (NYHA) functional class were assessed at 5 time points to evaluate heart function.Results Eighty-one participants were categorized into those without sarcopenia (34) and those with possible sarcopenia (47). Logistic linear regression showed albumin and possible sarcopenia to be predictors of malnutrition (odds ratio, 5.5; 95% confidence interval, 1.02–30.19). Family support was associated with nutrition status (P = .019). For patient heart function, the results of NYHA functional class and left ventricular ejection fraction improved over time after TAVI. The improvement in NYHA functional class at T2 was significantly different between the 2 groups compared with that at T0.Conclusions The nutrition level was higher among participants without sarcopenia than those with possible sarcopenia. Approximately 90% of the participants indicated that they had high family support. Demographic factors and albumin levels could be used to evaluate risk of malnutrition. Patients without possible sarcopenia showed greater improvement in NYHA class.
Background Poor sleep and history of weight cycling (HWC) are associated with worse cardiovascular health, yet limited research has evaluated the association between HWC and poor sleep patterns.Methods The American Heart Association Go Red for Women Strategically Focused Research Network cohort at Columbia University (n = 506; mean age, 37 ± 15.7 years; 61% racial/ethnic minority) was used to evaluate the cross-sectional associations of HWC and sleep at baseline and the prospective associations of HWC from baseline with sleep at the 1-year visit. History of weight cycling, defined as losing and gaining 10 lb or more at least once (excluding pregnancy), was self-reported. Sleep duration, sleep quality, insomnia severity, and obstructive sleep apnea risk were assessed using the validated Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Berlin questionnaires. Linear and logistic regression models, adjusted for age, race/ethnicity, education, health insurance status, pregnancy history, and menopausal status, were used to evaluate the relation of HWC with sleep.Results Most women reported 1 or more episodes of weight cycling (72%). In linear models of cross-sectional and prospective data, each additional weight cycling episode was related to shorter sleep duration, poorer sleep quality, longer sleep onset latency, greater insomnia severity, more sleep disturbances, lower sleep efficiency, and higher sleep medication use frequency. In the logistic models, HWC (≥1 vs 0 episodes) was associated with greater odds for short sleep, poor sleep quality, long sleep onset latency (≥26 minutes), high obstructive sleep apnea risk, and sleep efficiency lower than 85%.Conclusion History of weight cycling predicted poor sleep among women, suggesting that weight maintenance may represent an important strategy to promote sleep health. The potential bidirectional relationship between HWC and sleep requires further investigation.
Background Sodium restriction is difficult for most individuals with hypertension. Intention to limit sodium intake predicts behavior. Information on the determinants of intention to restrict sodium intake is limited.Objectives The aims of this study were to identify (1) determinants of intention to restrict high-sodium food intake and (2) sources of sodium consumed by patients with hypertension in Indonesia.Methods A cross-sectional study was conducted among adult patients with hypertension (n = 206) attending cardiac clinics. A researcher-developed and tested, self-administered questionnaire that included questions about sodium restriction and a high-sodium food inventory was distributed. The quantile regression method was used to identify determinants of intention to restrict dietary sodium.Results The mean age of the patients with hypertension was 59 ± 10 years, and more than three-fourths were obese (n = 162, 78%). The determinants of intention to limit sodium intake included gender (β = 0.737, P = .036), attitude (β = −0.141, P = .050), and subjective norm (β = −0.283, P = .005). Men reported higher sodium consumption, while attitudes and subjective norm were negatively correlated with sodium intake. These determinants predicted 13.2% of the variance in intention to restrict dietary sodium. Subjects reported frequently consuming snacks (n = 82, 39.7%) and seasoning condiments (n = 65, 31.6%).Conclusions High-sodium snacks and condiments added while cooking were frequently consumed among patients with hypertension in Indonesia. Understanding the factors associated with intention to follow a low-sodium diet will assist nurses to design effective interventions that promote adherence to the low-sodium diet among those with hypertension.
Background The patient experience of heart failure involves a multi-impact symptom response with functional limitations, psychological changes, and significant treatment burden.Objective The aim of this study was to examine the change in patient-reported outcomes in newly diagnosed patients with heart failure and reduced ejection fraction (HFrEF) prescribed a wearable cardioverter defibrillator.Methods Adults hospitalized for new-onset heart failure, due to ischemic or nonischemic cardiomyopathy, and prescribed a wearable cardioverter defibrillator within 10 days post discharge were approached for inclusion. Participants completed the Kansas City Cardiomyopathy Questionnaire at 3 time points: baseline, day 90, and day 180.Results A total of 210 patients (26% female) were included. All Kansas City Cardiomyopathy Questionnaire subscales (physical limitation, symptom frequency, quality of life, and social limitation) showed improvement from baseline to day 90 (all Ps < .001). Only quality of life continued to improve from day 90 to day 180 (P < .001). By day 90, nearly 70% of patients showed an improvement in quality of life (67.9%, n = 91), and by day 180, more than 80% (82.8%, n = 111) reported a net improvement. Five patients (3.7%) reported a net decrease, and 18 patients (13.4%) had no net change in quality of life during the 180-day period.Conclusion Patient-reported quality of life improved significantly among patients newly diagnosed with HFrEF and prescribed a wearable cardioverter defibrillator. These results suggest that pursuing guideline-directed medical therapy for HFrEF, while being protected by the wearable cardioverter defibrillator, is likely to provide symptom relief and improve quality of life.
Background The COVID-19 pandemic has altered catheterization laboratory (cath lab) practices in diverse ways.Objective The aim of this study was to understand the impact of COVID-19 on Veterans Affairs (VA) procedural volume and cath lab team experience.Methods Procedural volume and COVID-19 patient data were obtained from the Clinical, Assessment, Reporting and Tracking Program. A mixed methods survey was emailed to VA cath lab staff asking about the COVID-19 response. Descriptive and manifest content analyses were conducted.Results Procedural volume decreased from April to September 2020. One hundred four patients with known COVID-19 were treated. Survey response rate was 19% of staff (n = 170/902) from 83% of VA cath labs (n = 67/81). Reassignment to other units, confusion regarding COVID-19 testing, personal protective equipment use, and low patient volume were reported. Anxiety, burnout, and leadership's role on team morale were described.Conclusions Some teams adapted. Others expressed frustration over the lack of control over their practice. Leaders should routinely assess staff needs during the current and future crises.
Background ActiGraph accelerometry is widely used in nursing research to estimate daily physical activity. Heart rate variability (HRV), a measure of autonomic modulation, can be assessed in conjunction with the ActiGraph using a Polar H7 Bluetooth heart rate monitor. There is a paucity of nursing literature to guide nurse researchers' protocol development when using the ActiGraph to assess both physical activity and short-term HRV via its Bluetooth capabilities.Objectives The aim of this study was to describe a standardized research ActiGraph and HRV (ActiGraph HRV) protocol for an ongoing randomized controlled trial to measure physical activity and short-term HRV in patients with ischemic heart disease who report hopelessness.Methods We outline the study protocol for the standardization of reliable and rigorous physical activity and HRV data collection using the ActiGraph wGT3X-BT and Polar H7 Bluetooth heart rate monitor, and data analysis using ActiLife and Kubios software programs.Results Sixty-four participants enrolled in the randomized controlled trial to date, and 45 (70.3%) have completed or are actively participating in the study. Heart rate variability data have been collected on 43 of the 45 participants (96%) to date. During the first data collection time point, 42 of 44 participants (95.5%) wore the ActiGraph for a minimum of 5 valid days, followed by 28 of 31 participants (90.3%) and 25 of 26 participants (96.2%) at subsequent data collection time points. The intraclass correlation for physical activity in this study is 0.95 and 0.98 for HRV.Discussion Revisions to the protocol were successfully implemented at the onset of the COVID-19 pandemic for data collection using social distancing. The protocol was additionally amended in response to an unanticipated problem with ActiGraph battery life using Bluetooth technology. Use of the ActiGraph HRV protocol has led to a reliable and rigorous measurement of physical activity and HRV for patients with ischemic heart disease who report hopelessness in this randomized controlled trial.Conclusion We provide an ActiGraph HRV protocol that can be adapted as a model in the development of ActiGraph HRV protocols for future nursing research in community and home-based settings while maximizing social distancing in the current and future pandemics.
Background Difficulties in coping with and self-managing heart failure (HF) are well known. The COVID-19 pandemic may further complicate self-care practices associated with HF.Objective The aim of this study was to understand COVID-19's impact on HF self-care, as well as related coping adaptations that may blunt the impact of COVID-19 on HF health outcomes.Methods A qualitative study using phone interviews, guided by the framework of vulnerability analysis for sustainability, was used to explore HF self-care among older adults in central Texas during the late spring of 2020. Qualitative data were analyzed using directed content analysis.Results Seventeen older adults with HF participated (mean [SD] age, 68 [9.1] years; 62% female, 68% White, 40% below poverty line, 35% from rural areas). Overall, the COVID-19 pandemic had an adverse impact on the HF self-care behavior of physical activity. Themes of social isolation, financial concerns, and disruptions in access to medications and food indicated exposure, and rural residence and source of income increased sensitivity, whereas adaptations by healthcare system, health-promoting activities, socializing via technology, and spiritual connections increased resilience to the COVID-19 pandemic.Conclusions The study's findings have implications for identifying vulnerabilities in sustaining HF self-care by older adults and empowering older adults with coping strategies to improve overall satisfaction with care and quality of life.
Background The application of latent class growth analysis (LCGA) has been limited in behavioral studies on high–cardiovascular-risk populations.Aim The current study aimed to identify distinct health behavior trajectories in high–cardiovascular-risk populations using LCGA. We also examined the baseline individual characteristics associated with different health behavior trajectories and determined which trajectory is associated with improved cardiovascular risk outcomes at 52 weeks.Methods This secondary analysis of a clinical trial included 200 patients admitted to primary care clinics. Latent class growth analysis was conducted to identify the trajectories of physical activity and dietary intake; these were measured at 4 different time points during a 52-week study period. Analysis of variance/χ2 test was used to assess the associations between baseline individual characteristics and trajectories, and logistic regression analysis was used to identify associations between trajectories and cardiovascular risk outcomes at 52 weeks.Results Three trajectories were identified for physical activity (low-, moderate-, and high-stable). Risk perception, patient activation, and depressive symptoms predicted the trajectories. High-stable trajectory for physical activity was associated with better cardiovascular risk outcomes at the 52-week follow-up. Two trajectories (low-stable and high-decreasing) were identified for percent energy from fat, but the factors that can predict trajectories were limited.Conclusions Interventions are needed to target patients who begin with a lower physical activity level, with the goal of enhanced cardiovascular health. The predictors identified in the study may facilitate earlier and more tailored interventions.
