A large, multi-center survey assessing health, social support, literacy, and self-management resources in patients with heart failure.

BACKGROUND: Most patients with heart failure (HF) have multimorbidity which may cause difficulties with self-management. Understanding the resources patients draw upon to effectively manage their health is fundamental to designing new practice models to improve outcomes in HF. We describe the rationale, conceptual framework, and implementation of a multi-center survey of HF patients, characterize differences between responders and non-responders, and summarize patient characteristics and responses to the survey constructs among responders. METHODS: This was a multi-center cross-sectional survey study with linked electronic health record (EHR) data. Our survey was guided by the Chronic Care Model to understand the distribution of patient-centric factors, including health literacy, social support, self-management, and functional and mental status in patients with HF. Most questions were from existing validated questionnaires. The survey was administered to HF patients aged ≥ 30 years from 4 health systems in PCORnet® (the National Patient-Centered Clinical Research Network): Essentia Health, Intermountain Health, Mayo Clinic, and The Ohio State University. Each health system mapped their EHR data to a standardized PCORnet Common Data Model, which was used to extract demographic and clinical data on survey responders and non-responders. RESULTS: Across the 4 sites, 10,662 patients with HF were invited to participate, and 3330 completed the survey (response rate: 31%). Responders were older (74 vs. 71 years; standardized difference (95% CI): 0.18 (0.13, 0.22)), less racially diverse (3% vs. 12% non-White; standardized difference (95% CI): -0.32 (-0.36, -0.28)), and had higher prevalence of many chronic conditions than non-responders, and thus may not be representative of all HF patients. The internal reliability of the validated questionnaires in our survey was good (range of Cronbach's alpha: 0.50-0.96). Responders reported their health was generally good or fair, they frequently had cardiovascular comorbidities, > 50% had difficulty climbing stairs, and > 10% reported difficulties with bathing, preparing meals, and using transportation. Nearly 80% of patients had family or friends sit with them during a doctor visit, and 54% managed their health by themselves. Patients reported generally low perceived support for self-management related to exercise and diet. CONCLUSIONS: More than half of patients with HF managed their health by themselves. Increased understanding of self-management resources may guide the development of interventions to improve HF outcomes.

Long-term quality of life, psychological distress, and caregiver burden in octogenarians with LVAD: A single-centre experience.

With the general population aging, both life expectancy and the number of left ventricular assist device (LVAD) implantations in elderly patients are growing. Nevertheless, their perceived long-term quality of life, including psychological aspects, coupled with the respective caregiver's burden, remain under-reported. In light of the rising number of octogenarians with LVAD who necessitate broader healthcare provider involvement, we assessed the long-term quality of life, as defined by both the 36-item short-form health (SF-36) survey and the EuroQol 5 dimensions, 5-level questionnaire (EQ-5D-5L)-including the visual analog scale-in octogenarian LVAD patients who had received treatment at our institution. Additionally, we evaluated the psychological health of octogenarian LVAD patients using the psychological general well-being index (PGWBI), alongside their caregivers' well-being through the 22-item version of the Zarit Burden Interview (ZBI). Of 12 octogenarian LVAD patients, 5 were alive and willing to answer questionnaires. Mean age at implant was 74 ± 2 years. Median follow-up was 2464 (IQR = 2375-2745) days. Although variable, the degree of health and psychological well-being perceived by octogenarian patients with LVAD was "good." Interestingly, the burden of assistance reported by caregivers, though relevant, was greatly varied, suggesting the need to better define and address psychological long-term aspects related to LVAD implantation for both patients and caregivers with a broad-spectrum approach.

The relationship between caregiver contribution to self-care and patient quality of life in heart failure: A longitudinal mediation analysis.

BACKGROUND: Patients with heart failure may experience poor quality of life due to a variety of physical and psychological symptoms. Quality of life can improve if patients adhere to consistent self-care behaviors. Patient outcomes (i.e., quality of life) are thought to improve as a result of caregiver contribution to self-care. However, uncertainty exists on whether these outcomes improve as a direct result of caregiver contribution to self-care or whether this improvement occurs indirectly through the improvement of patient heart failure self-care behaviors. AIMS: To investigate the influence of caregiver contribution to self-care on quality of life of heart failure people and explore whether patient self-care behaviors mediate such a relationship. METHODS: This is a secondary analysis of the MOTIVATE-HF randomized controlled trial (Clinicaltrials.gov registration number: NCT02894502). Data were collected at baseline and 3 months. An autoregressive longitudinal path analysis model was conducted to test our hypotheses. RESULTS: We enrolled a sample of 510 caregivers [mean age = 54 (±15.44), 24% males)] and 510 patients [mean age = 72.4 (±12.28), 58% males)]. Patient self-care had a significant and direct effect on quality of life at three months (ß = 0.20, p < .01). Caregiver contribution to self-care showed a significant direct effect on patient self-care (ß = 0.32, p < .01), and an indirect effect on patient quality of life through the mediation of patient self-care (ß = 0.07, p < .001). CONCLUSION: Patient quality of life is influenced by self-care both directly and indirectly, through the mediation of caregiver contribution to self-care. These findings improve our understanding on how caregiver contribution to self-care improves patient outcomes.

Palliative Care in Adult Congenital Heart Disease-Associated Advanced Heart Disease.

The practice of palliative care (PC) strives to mitigate patient suffering through aligning patient priorities and values with care planning and via improved understanding of complex physical, psychosocial, and spiritual stressors and dynamics that contribute to patient-centered outcomes. Through representative 'case examples' and supportive data, the role and value of a PC consultant, within the framework of a comprehensive adult congenital heart disease (ACHD) team caring for ACHD with advanced heart disease, are reviewed.

High level of psychosocial adjustment in patients on ongoing ventricular assist device support in the years one to three after VAD implantation-A national multi-center Study.

BACKGROUND: Advanced heart failure therapies such as durable ventricular assist device (VAD) support require psychosocial adjustment for those affected. Since VAD implantation has become an established treatment strategy, a focus on psychosocial factors is needed. OBJECTIVES: To investigate the construct of psychosocial adjustment and to further understand the role of social support. METHODS: In a nation-wide, multi-center, cross-sectional study, we recruited 393 participants with ongoing VAD support (3mts-3yrs on device; clinicaltrials.gov ID: NCT04234230). Patient demographics, psychosocial adjustment (perceived social support, anxiety, depression, and quality of life), and major adverse events (thromboembolic events, bleeding, driveline infections) were assessed. RESULTS: Overall, 85.8 % of the sample were male; mean age was 58.3 years (range 18-85). The majority of the sample (89.3 %) reported normal to high perceived social support. Participants expressed symptoms of anxiety within the normal range (M=6.0±3.9), mildly elevated depressive symptoms (HADS: M=7.6±2.9; PHQ-9: M=6.2±4.7), and good quality of life (KCCQ: M=65.3±17.9). Higher perceived social support was associated with lower levels of anxiety and depression, and higher levels of quality of life within our sample (all p<0.001). Driveline infection was the most prevalent adverse event (0.304 infections per person-years [32.6 % of patients]). Binary logistic regression models did not identify significant associations for the occurrence of adverse events and variables of psychosocial adjustment. CONCLUSION: Our sample perceived high levels of psychosocial adjustment. High perceived social support was associated with better outcomes in levels of anxiety, depression, and quality of life, demonstrating potential for the future development and evaluation of targeted multi-professional social support interventions including peer- and caregiver support.

The role of illness perceptions in delayed care-seeking in heart failure: A mixed-methods study.

BACKGROUND: Unclear illness perceptions are common in heart failure. The self-regulation model of illness behaviour highlights factors that may impact how people with chronic illness choose to cope with or manage their condition and has been used to study pre-hospital delay for stroke and acute myocardial infarction. The principles of self-regulation can be applied in heart failure to help illuminate the link between unclear illness perceptions and sub-optimal symptom self-management. OBJECTIVE: Informed by the self-regulation model of illness behaviour, this study examines the role of illness perceptions in coping responses that lead to delayed care-seeking for heart failure symptoms. DESIGN: Mixed-methods phenomenological study. SETTING(S): Quaternary referral hospital - centre of excellence for cardiovascular care and heart transplantation. PARTICIPANTS: Seventy-two symptomatic patients with heart failure participated in a survey assessing illness perceptions. A subset of fifteen individuals was invited to participate in semi-structured interviews. METHODS: Illness perceptions were assessed using the Brief Illness Perception Questionnaire. In-depth semi-structured interviews were conducted to elicit previous care-seeking experiences and decision-making that led to a passive, or active coping response to worsening symptoms. Descriptive statistics were used to report questionnaire findings, and open-ended responses were grouped into descriptive categories. Interpretative phenomenological analysis was undertaken on interview transcripts. RESULTS: Participants perceived little personal control over their condition and mostly attributed heart failure to lifestyle factors such as diet and lack of activity. Cognitive dissonance between perceived self-identity and heart failure-identity led to a highly emotional response which drove coping towards avoidance strategies and denial. CONCLUSIONS: This study demonstrates the use of the principles of self-regulation in heart failure and offers a framework to understand how patient representations and emotional responses can inform behaviour in illness. Findings highlight the value of empowering patients to take control of their health and the need to help align values (e.g. independence) with behaviours (e.g. actively addressing problems) to facilitate optimal symptom self-management.

Computerized Cognitive Training and 24-Month Mortality in Heart Failure.

BACKGROUND: Cognitive dysfunction predicts mortality in heart failure (HF). Computerized cognitive training (CCT) has shown preliminary efficacy in improving cognitive function. However, the relationship between CCT and mortality is unclear. Aims were to evaluate (1) long-term efficacy of CCT in reducing 24-month mortality and (2) age, HF severity, global cognition, memory, working memory, depressive symptoms, and health-related quality of life as predictors of 24-month mortality among patients with HF. METHODS: In this prospective longitudinal study, 142 patients enrolled in a 3-arm randomized controlled trial were followed for 24 months. Logistic regression was used to achieve the aims. RESULTS: Across 24 months, 16 patients died (CCT, 8.3%; control groups, 12.8%). Computerized cognitive training did not predict 24-month mortality (odds ratio [OR], 0.65). Older age (OR, 1.08), worse global cognition (OR, 0.73), memory (OR, 0.81), and depressive symptoms (OR, 1.10) at baseline predicted 24-month mortality. CONCLUSIONS: Efficacious interventions are needed to improve global cognition, memory, and depressive symptoms and reduce mortality in HF.

What frail, older patients talk about when they talk about self-care-a qualitative study in heart failure care.

BACKGROUND: Self-care plays a crucial role in the management of heart failure (HF) and is especially important for older patients who are frail. However, there is limited knowledge about how frail, older patients with HF perceive and experience self-care. Therefore, the aim of this study was to describe the experiences of self-care among frail, older patients with HF. METHODS: A qualitative descriptive design with semi-structured interviews with frail, older patients diagnosed with HF (n = 19; median age 82 years). Thematic analysis, guided by Braun and Clarke, was used to analyse the data. RESULTS: Two main themes emerged from the analysis: 1) "To maintain my health," encompassing various aspects such as hygiene practices, engaging in physical activity, medication adherence, following a healthy diet, and ensuring adequate rest; and 2) "To maintain my well-being and happiness," highlighting the importance of hobbies, maintaining independence, participating in social activities, and creating a supportive environment. CONCLUSION: This study provides valuable insights into the perspectives of frail, older patients with HF regarding self-care. It was observed that older patients often associate self-care with general well-being, hygiene, and happiness. Clear communication between healthcare providers and patients is essential to align different perspectives on self-care and ensure that self-care plans are tailored to individual needs. Moreover, addressing the emotional well-being and happiness of patients should be prioritized, as these factors play a significant role in promoting self-care adherence.

The impact of palliative care on the physical and mental status and quality of life of patients with chronic heart failure: A randomized controlled trial.

BACKGROUND: Chronic heart failure (CHF) is the terminal stage of several diseases. The present study aimed to investigate the impact of palliative care on the physical and mental status and quality of life of patients with CHF. METHODS: This single-center randomized controlled clinical trial was conducted at Xiangtan Central Hospital. A total of 103 cases were included and divided into a study group (n = 54) and a control group (n = 49). The control group received usual care, whereas the study group received usual care plus palliative care. Statistical analyses were conducted on Simplified Coping Style Questionnaire, negative emotions, Minnesota Living with Heart Failure Questionnaire scores, and nursing satisfaction before and after intervention in the 2 groups. RESULTS: After the intervention, the positive coping style score in the research group was higher than that in the control group, while the negative coping style score was lower than that of the control group (P < .05). After the intervention, the Beck Anxiety Inventory and Beck Depression Inventory-II scores of the 2 groups decreased compared to before the intervention, and the study group had lower scores than the control group (P < .05). After the intervention, the Minnesota Living with Heart Failure Questionnaire scores of the 2 groups decreased compared to those before the intervention, and the study group had lower scores than the control group (P < .05). Nursing satisfaction of the research group (94.44%) was higher than that of the control group (81.63%) (P < .05). CONCLUSIONS: Adopting palliative care to intervene in CHF patients can effectively regulate their physical and mental state, alleviate negative emotions, transform coping styles towards the disease, and improve their quality of life, with high patient satisfaction.

Burden among informal caregivers of individuals with heart failure: A mixed methods study.

AIMS: To develop a comprehensive understanding of caregiver burden and its predictors from a dyadic perspective. METHOD: A convergent mixed methods design was used. This study was conducted in three European countries, Italy, Spain, and the Netherlands. A sample of 229 HF patients and caregivers was enrolled between February 2017 and December 2018 from the internal medicine ward, outpatient clinic, and private cardiologist medical office. In total, 184 dyads completed validated scales to measure burden, and 50 caregivers participated in semi-structured interviews to better understand the caregiver experience. The Care Dependency Scale, Montreal Cognitive Assessment, and SF-8 Health Survey were used for data collection. Multiple regression analysis was conducted to identify the predictors and qualitative content analysis was performed on qualitative data. The results were merged using joint displays. RESULTS: Caregiver burden was predicted by the patient's worse cognitive impairment, lower physical quality of life, and a higher care dependency perceived by the caregivers. The qualitative and mixed analysis demonstrated that caregiver burden has a physical, emotional, and social nature. CONCLUSIONS: Caregiver burden can affect the capability of informal caregivers to support and care for their relatives with heart failure. Developing and evaluating individual and community-based strategies to address caregiver burden and enhance their quality of life are warranted.

The Role of Palliative Care in Heart Failure, Part 3: Facilitators and Barriers to Cardiac Palliative Care Clinic Development.

Background: Patients with heart failure frequently have significant disease burden and complex psychosocial needs. The integration of palliative care into the management of these patients can decrease symptom burden throughout their course of illness. Therefore, in 2009, we established a cardiac palliative care clinic colocated with heart failure providers in a large academic heart hospital. Objective: To better understand the facilitators and barriers to integrating palliative care into our heart failure management service. Design: Qualitative study using a semistructured interview guide. Setting, Subjects: Between October 2020 and January 2021, we invited all 25 primary cardiac providers at our academic medical center in the midwestern United States to participate in semistructured qualitative interviews to discuss their experiences with the cardiac palliative care clinic. Measurements: Interview transcripts were analyzed using a deductive-dominant thematic analysis approach to reveal emerging themes. Results: Providers noted that the integration of palliative care into the treatment of patients with heart failure was helped and hindered primarily by issues related to operations and communications. Operational themes about clinic proximity and the use of telehealth as well as communication themes around provider-provider communication and the understanding of palliative care were particularly salient. Conclusions: The facilitators and barriers identified have broad applicability that are independent of the etiological nature (e.g., cancer, pulmonary, neurological) of any specialty or palliative care clinic. Moreover, the strategies we used to implement improvements in our clinic may be of benefit to other practice models such as independent and embedded clinics.

A Mixed-Methods Study of Social Determinants and Self-care in Adults With Heart Failure.

BACKGROUND: The burden of heart failure (HF) is unequally distributed among population groups. Few study authors have described social determinants of health (SDoH) enabling/impeding self-care. AIM: The aim of this study was to explore the relationship between SDoH and self-care in patients with HF. METHODS: Using a convergent mixed-methods design, we assessed SDoH and self-care in 104 patients with HF using the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) and the Self-Care of HF Index v7.2 with self-care maintenance, symptom perception, and self-care management scales. Multiple regression was used to assess the relationship between SDoH and self-care. One-on-one in-depth interviews were conducted in patients with poor (standardized score ≤ 60, n = 17) or excellent (standardized score ≥ 80, n = 20) self-care maintenance. Quantitative and qualitative results were integrated. RESULTS: Participants were predominantly male (57.7%), with a mean age of 62.4 ± 11.6 years, with health insurance (91.4%) and some college education (62%). Half were White (50%), many were married (43%), and most reported adequate income (53%). The money and resources core domain of PRAPARE significantly predicted self-care maintenance ( P = .019), and symptom perception ( P = .049) trended significantly after adjusting for other PRAPARE core domains (personal characteristics, family and home, and social and emotional health) and comorbidity. Participants discussed social connectedness, health insurance coverage, individual upbringing, and personal experiences as facilitators of self-care behavior. CONCLUSION: Several SDoH influence HF self-care. Patient-specific interventions that address the broader effects of these factors may promote self-care in patients with HF.

Outcomes of a tailored self-care intervention for patients with heart failure and major depression: A secondary analysis of a randomized controlled trial.

BACKGROUND: Depression is a recognized barrier to heart failure self-care, but there has been little research on interventions to improve heart failure self-care in depressed patients. OBJECTIVES: To investigate the outcomes of an individually tailored self-care intervention for patients with heart failure and major depression, and to determine whether the adequacy of self-care at baseline, the severity of depression or anxiety, or other factors affect the outcomes of this intervention. DESIGN: Secondary analysis of data from a pre-registered randomized controlled trial (NCT02997865). METHODS: Outpatients with heart failure and comorbid major depression (n = 139) were randomly assigned to cognitive behavior therapy or usual care for depression. In addition, an experienced cardiac nurse provided the tailored self-care intervention to all patients in both arms of the trial starting eight weeks after randomization. Weekly self-care intervention sessions were held between Weeks 8 and 16; the frequency was tapered to biweekly or monthly between Weeks 17 and 32. The Self-Care of Heart Failure Index (v6.2) was used to assess self-care outcomes, with scores ≥70 on each of its three scales (Maintenance, Management, and Confidence) being consistent with adequate self-care. The Week 16 Maintenance scale score was the primary outcome for this analysis. RESULTS: At baseline, 107 (77%) of the patients scored in the inadequate self-care range on the Maintenance scale. Between Weeks 8 and 16, Maintenance scores improved more in patients with initially inadequate than initially adequate self-care (11.9 vs. 3.2 points, p = .003). Sixty-six (48%) of the patients with initially inadequate Maintenance scores achieved scores in the adequate range by Week 32 (p < .0001). Covariate-adjusted predictors of better Maintenance outcomes included adequate Maintenance at baseline (p < .0001), higher anxiety at baseline (p < .05), and higher dosages of the self-care intervention (p < .0001). Neither treatment with cognitive behavior therapy nor less severe major depression predicted better self-care outcomes. CONCLUSIONS: Depressed patients with inadequate heart failure self-care are able to achieve clinically significant improvements in self-care with the help of an individually tailored self-care intervention. Further refinement and testing are needed to increase the intervention's potential for clinical implementation.

Effects of an autonomy-supportive intervention programme (ASIP) on self-care, quality of life, and mental health in heart failure patients: a randomized controlled trial.

PURPOSE: Patients with heart failure (HF) possess low self-care activation and motivation, leading to a deprived quality of life and adverse mental health conditions. To this end, self-determination theory emphasizes that autonomy-supportive interventions (ASI) can stimulate intrinsic motivation and improve behaviors and quality of life. Nevertheless, studies that focused on ASI for HF are inadequate. This study aims to evaluate the effects of an HF-ASIP on self-care, quality of life and mental health in HF patients. METHODS: In a two-arm randomized controlled trial, the participants are randomly allocated to the intervention (n = 41) or control (n = 41) groups. The intervention group received routine care and participated in an 8-week HF-ASIP, including individual education and consultation sessions. In contrast, the control group received only routine care. The primary outcome includes self-care management, while the secondary outcomes include self-care maintenance, quality of life, mental health, and motivation. After measuring the outcomes at baseline (T0), 4-week (T1), 8-week (T2), and 12-week (T3) follow-up, the intervention effects are assessed using the generalized equation models. RESULTS: The outcomes indicated that self-care management (T2: P = 0.001; T3: P = 0.016), self-care maintenance (T2: P = 0.003; T3: P = 0.001), depression (T2: P = 0.007; T3: P = 0.012), anxiety (T2: P = 0.001; T3: P = 0.012), MLHFQ total score (T1: P = 0.004; T2: P < 0.001; T3: P = 0.001), autonomous motivation (T2: P = .0.006; T3: P = 0.002) showed statistically difference between the groups. CONCLUSION: In summary, the 8-week HF-ASIP significantly improved the attributes of self-care, quality of life, mental health, and motivation in HF patients, suggesting the potential for practical intervention effect.

Historical Redlining, Socioeconomic Distress, and Risk of Heart Failure Among Medicare Beneficiaries.

BACKGROUND: The association of historical redlining policies, a marker of structural racism, with contemporary heart failure (HF) risk among White and Black individuals is not well established. METHODS: We aimed to evaluate the association of redlining with the risk of HF among White and Black Medicare beneficiaries. Zip code-level redlining was determined by the proportion of historically redlined areas using the Mapping Inequality Project within each zip code. The association between higher zip code redlining proportion (quartile 4 versus quartiles 1-3) and HF risk were assessed separately among White and Black Medicare beneficiaries using generalized linear mixed models adjusted for potential confounders, including measures of the zip code-level Social Deprivation Index. RESULTS: A total of 2 388 955 Medicare beneficiaries (Black n=801 452; White n=1 587 503; mean age, 71 years; men, 44.6%) were included. Among Black beneficiaries, living in zip codes with higher redlining proportion (quartile 4 versus quartiles 1-3) was associated with increased risk of HF after adjusting for age, sex, and comorbidities (risk ratio, 1.08 [95% CI, 1.04-1.12]; P<0.001). This association remained significant after further adjustment for area-level Social Deprivation Index (risk ratio, 1.04 [95% CI, 1.002-1.08]; P=0.04). A significant interaction was observed between redlining proportion and Social Deprivation Index (Pinteraction<0.01) such that higher redlining proportion was significantly associated with HF risk only among socioeconomically distressed regions (above the median Social Deprivation Index). Among White beneficiaries, redlining was associated with a lower risk of HF after adjustment for age, sex, and comorbidities (risk ratio, 0.94 [95% CI, 0.89-0.99]; P=0.02). CONCLUSIONS: Historical redlining is associated with an increased risk of HF among Black patients. Contemporary zip code-level social determinants of health modify the relationship between redlining and HF risk, with the strongest relationship between redlining and HF observed in the most socioeconomically disadvantaged communities.

Treatment of depression and inadequate self-care in patients with heart failure: One-year outcomes of a randomized controlled trial.

OBJECTIVE: Both depression and inadequate self-care are common in patients with heart failure. This secondary analysis examines the one-year outcomes of a randomized controlled trial of a sequential approach to treating these problems. METHODS: Patients with heart failure and major depression were randomly assigned to usual care (n = 70) or to cognitive behavior therapy (n = 69). All patients received a heart failure self-care intervention starting 8 weeks after randomization. Patient-reported outcomes were assessed at Weeks 8, 16, 32, and 52. Data on hospital admissions and deaths were also obtained. RESULTS: One year after randomization, Beck Depression Inventory (BDI-II) scores were - 4.9 (95% C.I., -8.9 to -0.9; p < .05) points lower in the cognitive therapy than the usual care arm, and Kansas City Cardiomyopathy scores were 8.3 (95% C.I., 1.9 to 14.7; p < .05) points higher. There were no differences on the Self-Care of Heart Failure Index or in hospitalizations or deaths. CONCLUSIONS: The superiority of cognitive behavior therapy relative to usual care for major depression in patients with heart failure persisted for at least one year. Cognitive behavior therapy did not increase patients' ability to benefit from a heart failure self-care intervention, but it did improve HF-related quality of life during the follow-up period. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT02997865.

Changes in cognitive function and daytime sleepiness in patients with chronic heart failure and Cheyne-Stokes respiration with adaptive servo ventilation treatment.

STUDY OBJECTIVES: Cheyne - Stokes respiration (CSR) is prevalent in patients with chronic heart failure (CHF). Adaptive Servo Ventilation (ASV) alleviates CSR and improves objective sleep quality. We investigated the effects of ASV on neurocognitive function in the symptomatic phenotype of patients with CSR and CHF. METHODS: This case series included patients diagnosed with stable CHF (NYHA ≥ II) and CSR (N = 8). Sleep and neurocognitive function were assessed at baseline and after 1- and 6-months following initiation of ASV treatment. RESULTS: In CHF patients (n = 8, median age 78.0[64.5-80.8] years and BMI 30.0[27.0-31.5] kg/m2, median ejection fraction 30[24-45]%, Epworth Sleepiness Scale (ESS) score 11.5[9.0-15.0]), ASV markedly improved respiration during sleep (Apnea-Hypopnea Index (AHI) 44.1[39.0-51.5]n/h at baseline, 6.3[2.4-9.7]n/h at 6 months treatment, respectively, p < 0.01). The 6-min-walk test distance increased by treatment from (295.0[178.8-385.0] m to 356.0[203.8-495.0] m (p = 0.05)). Sleep structure was modified, and Stage 3 increased markedly from 6.4[1.7-20.1] % to 20.8[14.2-25.3] %, p < 0.02). Sleep latency in the Maintenance of Wakefulness Test increased from 12.0[6.0-30.0] min to 26.3[12.0-30.0] min, (p = 0.04). In the Attention Network Test, evaluating neurocognition, the number of lapses decreased from 6.0[1.0-44.0] to 2.0[0.3-8.0], (p = 0.05) and the overall number of responses to a preset stimulus increased after treatment (p = 0.04). CONCLUSIONS: ASV treatment in CHF patients with CSR may improve sleep quality, neurocognition and daytime performance.

Coping styles as predictors for quality of life and prognosis in patients at risk for or with a diagnosis of heart failure: Results from the observational DIAST-CHF study.

OBJECTIVE: Patients with heart failure often experience impaired health-related quality of life (HRQOL) and have an increased risk of cardiovascular and cerebrovascular events. The aim of this study was to investigate the predictive role of different coping styles on outcome. METHODS: This longitudinal study included 1536 participants who either had cardiovascular risk factors or were diagnosed with heart failure. Follow-ups took place one, two, five and ten years after recruitment. Coping and HRQOL were investigated using self-assessment questionnaires (Freiburg Questionnaire for Coping with Illness, Short Form-36 Health Survey). Somatic outcome was quantified by incidence of major adverse cardiac and cerebrovascular events (MACCE) and 6-min-walking-distance. RESULTS: Pearson correlation and multiple linear regression analysis showed significant associations between the coping styles used at the first three time points and HRQOL after five years. After adjusting for baseline HRQOL, minimization and wishful thinking predicted worse mental HRQOL (ß = -0.106; p = 0.006), while depressive coping predicted worse mental (ß = -0.197; p < 0.001) and physical HRQOL (ß = -0.085; p = 0.03; n = 613). Active problem-oriented coping could not significantly predict HRQOL. Only minimization and wishful thinking was significantly associated with an increased 10-year-risk for MACCE (hazard ratio = 1.06; 95% confidence interval: 1.01-1.11; p = 0.02; n = 1444) and reduction in 6-min-walking-distance at 5 years (ß = -0.119; p = 0.004; n = 817) in adjusted analyses. CONCLUSIONS: Depressive coping and minimization and wishful thinking were associated with worse quality of life in patients at risk for or with diagnosed heart failure. Minimization and wishful thinking also predicted worse somatic outcome. Therefore, patients using those coping styles might benefit from early psychosocial interventions.

The Influence of Informal Caregivers' Preparedness on Psychological Symptoms and Quality of Life Among Patients With Heart Failure And Insufficient Self-care.

BACKGROUND: Most patients with heart failure find self-care difficult to perform and rely on family caregivers for support. Informal caregivers, however, often face insufficient psychological preparation and challenges in providing long-term care. Insufficient caregiver preparedness not only results in psychological burden for the informal caregivers but may also lead to a decline in caregiver contributions to patient self-care that affects patient outcomes. OBJECTIVE: Our objective was to test (1) the association of baseline informal caregivers' preparedness with psychological symptoms (anxiety and depression) and quality of life 3 months after baseline among patients with insufficient self-care and (2) the mediating effects of caregivers' contributions to self-care of heart failure (CC-SCHF) on the relationship of caregivers' preparedness with patients' outcomes at 3 months. METHODS: A longitudinal design was used to collect data between September 2020 and January 2022 in China. Data analyses were conducted using descriptive statistics, correlations, and linear mixed models. We used model 4 of the PROCESS program in SPSS with bootstrap testing to evaluate the mediating effect of CC-SCHF of informal caregivers' preparedness at baseline with psychological symptoms or quality of life among patients with HF 3 months later. RESULTS: Caregiver preparedness was positively associated with CC-SCHF maintenance ( r = 0.685, P < .01), CC-SCHF management ( r = 0.403, P < .01), and CC-SCHF confidence ( r = 0.600, P < .01). Good caregiver preparedness directly predicted lower psychological symptoms (anxiety and depression) and higher quality of life for patients with insufficient self-care. The associations of caregiver preparedness with short-term quality of life and depression of patients with HF with insufficient self-care were mediated by CC-SCHF management. CONCLUSIONS: Enhancing the preparedness of informal caregivers may improve psychological symptoms and quality of life of heart failure patients with insufficient self-care.

A Qualitative Study on the Self-Care Experiences of People with Heart Failure.

We aimed to explore in-depth experiences and emotions of people with heart failure within the context of self-care. A qualitative descriptive study was conducted using semi-structured interviews. Ten patients were recruited from an outpatient clinic at a university-affiliated hospital in South Korea between September and November 2019. Data were analyzed using a thematic content analysis approach. Participants were 68-86 years old, and 80% were men. Five themes of the self-care experiences of persons with heart failure were identified: "Suddenly diagnosed with heart failure," "Unpredictable symptoms and unprepared for self-care," "Dependent on caring family on a heartbreaking uphill," "Self-care efforts with apprehension," and "Continued self-care efforts with expert help." Programs to support self-care for people with heart failure are needed and should be developed by incorporating patients' needs and reflecting their uncertainty and vulnerability.
