Does heart failure-specific health status identify patients with bothersome symptoms, depression, anxiety, and/or poorer spiritual well-being?

Correlation between symptom status, health perception, and spiritual well-being in heart failure patients: A structural equation modeling approach

AIM

To explore predictors of spiritual well-being behaviors among heart failure patients based on Wilson and Cleary's conceptual model of health-related quality of life and to clarify the interrelationships among these variables.

DESIGN

A descriptive and correlational study design was used.

METHODS

This study included 202 heart failure patients treated between October 2020 and July 2021. Data were collected using the Symptom Status Questionnaire-Heart Failure, Perception of Health Scale, and Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale. Descriptive analysis, correlation, and structural equation modeling were performed.

RESULTS

Characteristic factors positively affected spiritual well-being both directly (β = 0.19, p = 0.007) and indirectly (β = 0.19; CI (0.106; 0.311)). The direct relationship between health perception and spiritual well-being was significant (β = 0.83, p < 0.05). Symptom status acted as an essential mediator between model variables and spiritual well-being (β = -0.28; CI (-0.449; -0.133)). Comorbidity and symptom status also influence spiritual well-being through health perceptions. These variables explain 77% of the variance in spiritual well-being.

CONCLUSION

The modified structural equation modeling based on Wilson and Cleary's conceptual model fits well in predicting spiritual well-being in patients with heart failure. Spiritual well-being was reported to be poor, and changes in spiritual well-being were predicted by age, educational level, marital status, comorbidity, symptom status, and health perception. The results can be applied to patients with heart failure and may serve as a guide for assessment and interventions for improving spiritual well-being.

CLINICAL RELEVANCE

This study mainly concludes that symptom status and perceived health status affect spiritual well-being in heart failure patients. Symptom relief and improvement in perceived health status interventions may help enhance spiritual well-being in this population. Future studies are needed to investigate the different predictor's effects on spiritual well-being and examine whether symptom management and health status-enhancing interventions result in improved spiritual well-being in the heart failure population.

REPORTING METHOD

This study was reported following the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for cross-sectional studies.

SGLT2 Inhibitors, Functional Capacity, and Quality of Life in Patients With Heart Failure: A Systematic Review and Meta-Analysis

Importance

The associations of sodium glucose cotransporter-2 inhibitors (SGLT2is) with reduction in mortality and hospitalization rates in patients with heart failure (HF) are well established. However, their association with improving functional capacity and quality of life (QOL) has been variably studied and less reported.

Objective

To provide evidence on the extent to which SGLT2is are associated with improvement on objective measures of functional capacity and QOL in patients living with HF.

Data Sources

The MEDLINE, EMBASE, and Cochrane databases were systematically searched for relevant articles on July 31, 2023.

Study Selection

Randomized, placebo-controlled clinical trials reporting the effect of SGLT2i on functional outcomes of exercise capacity (peak oxygen consumption [peak VO2] or 6-minute walk distance [6MWD]) and/or QOL using validated questionnaires for patients with HF were included.

Data Extraction and Synthesis

Data were extracted by 2 authors following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, and a meta-analysis using the restricted maximum likelihood random-effects model was conducted.

Main Outcomes and Measures

Outcomes of interest included changes in peak VO2, 6MWD, and Kansas City Cardiomyopathy Questionnaire-12 total symptom score (KCCQ-TSS), clinical summary score (KCCQ-CSS), and overall summary score (KCCQ-OSS).

Results

In this meta-analysis of 17 studies, 23 523 patients (mean [range] age, 69 [60-75] years) were followed over a period ranging from 12 to 52 weeks. Four studies included peak VO2 as an outcome, 7 studies included 6MWD, and 10 studies reported KCCQ scores. Mean (SD) left ventricular ejection fraction was 43.5% (12.4%). Compared with controls, patients receiving SGLT2i treatment experienced significant increases in peak VO2 (mean difference [MD], 1.61 mL/kg/min; 95% CI, 0.59-2.63 mL/kg/min; P = .002) and 6MWD (MD, 13.09 m; 95% CI, 1.20-24.97 m; P = .03). SGLT2i use was associated with increased KCCQ-TSS (MD, 2.28 points; 95% CI, 1.74-2.81 points; P < .001), KCCQ-CSS (MD, 2.14 points; 95% CI, 1.53-2.74 points; P < .001), and KCCQ-OSS (MD, 1.90 points; 95% CI, 1.41-2.39 points; P < .001) scores. Subgroup analysis and meta-regression demonstrated almost all improvements were consistent across ejection fraction, sex, and the presence of diabetes.

Conclusions and Relevance

These findings suggest that in addition to known clinical associations with mortality and hospitalization outcomes, SGLT2i use is associated with improvement in outcomes of interest to patients' everyday lives as measured by objective assessments of maximal exercise capacity and validated QOL questionnaires, regardless of sex or ejection fraction.

Association of Depression and Anxiety with Cardiac Structural and Functional Characteristics in Heart Failure with Reduced and Mildly Reduced Ejection Fraction

Heart failure and mental health conditions frequently coexist and have a negative impact on health-related quality of life and prognosis. We aimed to evaluate depression and anxiety symptoms and to determine the association between psychological distress and cardiac parameters in heart failure with reduced and mildly reduced ejection fraction. A total of 43 patients (33 male, mean age 64 ± 10 years) with heart failure and left ventricular systolic dysfunction (29 with HFrEF, 14 with HFmrEF) underwent comprehensive echocardiographic evaluation. All study participants completed questionnaires for the assessment of depression (PHQ-9), anxiety (GAD-7), and health-related quality of life (MLHFQ). Ten (34%) patients with HFrEF and two (14%) participants with HFmrEF had moderate-to-severe depression symptoms. Significant anxiety symptoms were more frequent in HFrEF (10 vs. 2 patients; 34% vs. 14%). Poor quality of life was also more common among patients with HFrEF (17 vs. 5 patients; 59% vs. 36%), showing higher MLHFQ scores (p = 0.009). Moreover, PHQ-9, GAD-7, and MLHFQ scores showed significant correlations between NYHA class severity and the presence of peripheral edema. The symptoms of dyspnea correlated with both PHQ-9 and MLHFQ scores. Significant correlations were observed between MLHFQ scores and a large number of clinical features, such as exercise capacity, 6MWT distance, the need for furosemide, echocardiographic parameters (LVEDVI, LVESVI, LVEF, LVGLS, SVI), and laboratory variables (albumin, GFR, NT-proBNP). In the multiple linear regression analysis, dyspnea proved to be a significant predictor of higher PHQ-9 and MLHFQ scores, even after adjusting for potential confounders. High symptom burden due to psychological distress is common among patients with HFrEF and HFmrEF. More efficient control of congestion may improve depression, anxiety symptoms, and health-related quality of life.

Association between dietary theobromine with depression: a population-based study

OBJECTIVE

The purpose of this study is to investigate the possible link between dietary theobromine intake and symptoms of depression.

MATERIALS AND METHODS

These results are based on the responses of 3637 people who took part in the National Health and Nutrition Examination Survey in 2017-2018. Participants' daily theobromine intake was determined using a 24-h food questionnaire from the 2017-2018 cycle. Presence of depression was defined as a score of 5 or above on the Patient Health Questionnaire. Association between theobromine intake and depression was examined using a multivariate logistic regression adjusting for several relevant sociodemographic, lifestyle and health-related factors.

RESULTS

A total of 6903 participants were included in the study. The results of multivariate logistic regression showed a correlation between depressive symptoms and theobromine intake (OR:1.17, 95%CI:1.02-1.34).

CONCLUSIONS

Our cross-sectional population based study suggests that increased theobromine intake is associated with increased risk for depression. Nevertheless, more investigations are needed to confirm our findings.

Spirituality in Patients With Heart Failure

With advances in heart failure (HF) treatment, patients are living longer, putting further emphasis on quality of life (QOL) and the role of palliative care principles in their care. Spirituality is a core domain of palliative care, best defined as a dynamic, multidimensional aspect of oneself for which 1 dimension is that of finding meaning and purpose. There are substantial data describing the role of spirituality in patients with cancer but a relative paucity of studies in HF. In this review article, we explore the current knowledge of spirituality in patients with HF; describe associations among spirituality, QOL, and HF outcomes; and propose clinical applications and future directions regarding spiritual care in this population. Studies suggest that spirituality serves as a potential target for palliative care interventions to improve QOL, caregiver support, and patient outcomes including rehospitalization and mortality. We suggest the development of a spirituality-screening tool, similar to the Patient Health Questionnaire-2 used to screen for depression, to identify patients with HF at risk for spiritual distress. Novel tools are soon to be validated by members of our group. Given spirituality in HF remains less well studied compared with other patient populations, further controlled trials and uniform measures of spirituality are needed to understand its impact better.

Artificial Intelligence-Enhanced Smartwatch ECG for Heart Failure-Reduced Ejection Fraction Detection by Generating 12-Lead ECG

BACKGROUND

We developed and validated an artificial intelligence (AI)-enabled smartwatch ECG to detect heart failure-reduced ejection fraction (HFrEF).

METHODS

This was a cohort study involving two hospitals (A and B). We developed the AI in two steps. First, we developed an AI model (ECGT2T) to synthesize ten-lead ECG from the asynchronized 2-lead ECG (Lead I and II). ECGT2T is a deep learning model based on a generative adversarial network, which translates source ECGs to reference ECGs by learning styles of the reference ECGs. For this, we included adult patients aged ≥18 years from hospital A with at least one digitally stored 12-lead ECG. Second, we developed an AI model to detect HFrEF using a 10 s 12-lead ECG. The AI model was based on convolutional neural network. For this, we included adult patients who underwent ECG and echocardiography within 14 days. To validate the AI, we included adult patients from hospital B who underwent two-lead smartwatch ECG and echocardiography on the same day. The AI model generates a 10 s 12-lead ECG from a two-lead smartwatch ECG using ECGT2T and detects HFrEF using the generated 12-lead ECG.

RESULTS

We included 137,673 patients with 458,745 ECGs and 38,643 patients with 88,900 ECGs from hospital A for developing the ECGT2T and HFrEF detection models, respectively. The area under the receiver operating characteristic curve of AI for detecting HFrEF using smartwatch ECG was 0.934 (95% confidence interval 0.913-0.955) with 755 patients from hospital B. The sensitivity, specificity, positive predictive value, and negative predictive value of AI were 0.897, 0.860, 0.258, and 0.994, respectively.

CONCLUSIONS

An AI-enabled smartwatch 2-lead ECG could detect HFrEF with reasonable performance.

Hotspot and Frontier Analysis of Exercise Training Therapy for Heart Failure Complicated With Depression Based on Web of Science Database and Big Data Analysis

Background: Exercise training has been extensively studied in heart failure (HF) and psychological disorders, which has been shown to worsen each other. However, our understanding of how exercise simultaneously protect heart and brain of HF patients is still in its infancy. The purpose of this study was to take advantage of big data techniques to explore hotspots and frontiers of mechanisms that protect the heart and brain simultaneously through exercise training.

Methods: We studied the scientific publications on related research between January 1, 2003 to December 31, 2020 from the WoS Core Collection. Research hotspots were assessed through open-source software, CiteSpace, Pajek, and VOSviewer. Big data analysis and visualization were carried out using R, Cytoscape and Origin.

Results: From 2003 to 2020, the study on HF, depression, and exercise simultaneously was the lowest of all research sequences (two-way ANOVAs, p < 0.0001). Its linear regression coefficient r was 0.7641. The result of hotspot analysis of related keyword-driven research showed that inflammation and stress (including oxidative stress) were the common mechanisms. Through the further analyses, we noted that inflammation, stress, oxidative stress, apoptosis, reactive oxygen species, cell death, and the mechanisms related to mitochondrial biogenesis/homeostasis, could be regarded as the primary mechanism targets to study the simultaneous intervention of exercise on the heart and brain of HF patients with depression.

Conclusions: Our findings demonstrate the potential mechanism targets by which exercise interferes with both the heart and brain for HF patients with depression. We hope that they can boost the attention of other researchers and clinicians, and open up new avenues for designing more novel potential drugs to block heart-brain axis vicious circle.

Spiritual Wellbeing of Cancer Patients: What Health-Related Factors Matter?

This study aimed to determine the predictors of spiritual wellbeing of non-terminal stage cancer patients hospitalized in oncology units in Lithuania. An exploratory cross-sectional study design was employed. During structured face-to-face interviews, 226 cancer patients hospitalized in oncology units responded about their spiritual wellbeing, perception of happiness, satisfaction with life, pain intensity, levels of education and physical functioning, and length of inpatient stay. A set of standardized tools were used: spiritual wellbeing scale SHALOM, brief multidimensional life satisfaction scale, Oxford Happiness Questionnaire, Barthel Index questionnaire, and verbal pain intensity scale. Additionally, social- and health-related factors were included in data analyses. Structural equation modeling was adapted for a comprehensive assessment of the mediating effect of spiritual wellbeing on the relationship between different health- and value-related factors. The overall fit of the structural model was generally good: [Formula: see text] = 66.94 (χ²/df = 2.31), CFI = 0.94, RMSEA = 0.08, and SRMR = 0.06. Data were analyzed using the Statistical Package for Social Sciences (IBM SPSS Statistics) version 24.0 and Mplus version 8.2. Level of happiness, life satisfaction, and spiritual wellbeing scored in the moderate upper range. The communal domain of spiritual wellbeing rated with the highest mean score and transcendental domain with the lowest score. Education (b = 0.208, p = 0.004), physical functioning (b = 0.171, p = 0.025), and hospital duration (b = - 0.240, p = 0.001) were significant predictors of spiritual wellbeing. Happiness and life satisfaction were negatively influenced by pain intensity, which ranged from mild to moderate. Levels of education, physical functioning, and length of hospital stay predict spiritual wellbeing of non-terminally ill cancer patients. Happiness, as well as life satisfaction, was negatively predicted by pain intensity but had no direct influence on spiritual wellbeing of cancer patients. Spiritual wellbeing positively influences emotional wellbeing (happiness and life satisfaction), and its influence is stronger than the negative influence of physical pain has on emotional wellbeing.

Palliative Care in Acute Heart Failure

Purpose of Review

Palliative care is increasingly acknowledged as beneficial in supporting patients and families affected by heart failure, but policy documents have generally focused on the chronic form of this disease. We examined palliative care provision for those with acute heart failure, based on the recently updated National Consensus Project Clinical Practice Guidelines for Quality Palliative Care.

Recent Findings

The commonest reason for hospitalization in those > 65 years, acute heart failure admissions delineate crisis points on the unpredictable disease trajectory. Palliative care is underutilized, often perceived as limited to end-of-life care rather than determined by regular systematic needs assessment. No dominant paradigm of palliative care provision has emerged from the nascent evidence base related to this clinical cohort, underscoring the need for further research.

Summary

Embedding palliative support as mainstream to heart failure care from the point of diagnosis may better ensure treatment strategies for those admitted with acute heart failure remain consistent with patients’ preferences and values.

Integration of a palliative approach into heart failure care: a European Society of Cardiology Heart Failure Association position paper

The Heart Failure Association of the European Society of Cardiology has published a previous position paper and various guidelines over the past decade recognizing the value of palliative care for those affected by this burdensome condition. Integrating palliative care into evidence-based heart failure management remains challenging for many professionals, as it includes the identification of palliative care needs, symptom control, adjustment of drug and device therapy, advance care planning, family and informal caregiver support, and trying to ensure a 'good death'. This new position paper aims to provide day-to-day practical clinical guidance on these topics, supporting the coordinated provision of palliation strategies as goals of care fluctuate along the heart failure disease trajectory. The specific components of palliative care for symptom alleviation, spiritual and psychosocial support, and the appropriate modification of guideline-directed treatment protocols, including drug deprescription and device deactivation, are described for the chronic, crisis and terminal phases of heart failure.

Utility of the integrated palliative care outcome scale (IPOS): a cross-sectional study in hospitalised patients with heart failure

AIM

The aim of this study was to evaluate the suitability and comprehensibility of the integrated palliative care outcome scale for the evaluation of palliative care needs in patients with heart failure.

METHODS AND RESULTS

This cross-sectional study investigated 100 heart failure patients (40 women, 60 men; median age 79 years) within the first few days of their hospitalisation by applying the integrated palliative care outcome scale (3-day recall period) and two additional self-developed questions about the suitability and comprehensibility of the integrated palliative care outcome scale. Clinically relevant somatic and psycho-emotional symptoms were reported very frequently (approximately 75% each), followed by communicational needs or practical issues. Ninety-five per cent of patients thought the integrated palliative care outcome scale very easy to understand, and 91% judged the integrated palliative care outcome scale suitable to assess palliative care needs.

CONCLUSION

The integrated palliative care outcome scale was well accepted by hospitalised patients with heart failure and identified a high burden of both physical and psycho-emotional symptoms. Screening for palliative care has to consider patients and their relatives alike, and should be part of a comprehensive care concept jointly integrated into clinical routine by primary and specialised palliative care teams.
