Psychological Disorders in Heart Failure

Assessing Heart Failure Self-management Knowledge Through Vignettes

BACKGROUND

Heart failure (HF) self-care is key to managing symptoms, but current HF knowledge instruments are at risk for social desirability bias (ie, tendency to respond in a way that is viewed favorably). Vignettes may be a useful method to mitigate this bias by measuring knowledge via scenarios in which individuals with HF are invited to respond to fictional characters' self-management problems rather than disclosing their own practices.

OBJECTIVE

The aims of the study were to develop and test the content validity of vignettes measuring individuals' knowledge of HF symptom self-management.

METHODS

The study had 3 phases. In phase 1, two vignettes were developed. One focused on psychological symptom self-management (ie, anxiety, depression), and the other focused on physical symptom self-management (ie, edema, fatigue). In phase 2, the research team and lay experts made improvements to the vignettes' readability. In phase 3, five HF self-care nurse experts evaluated the vignettes' clarity and importance with a 3-point Likert-type scale using Delphi methods. We calculated the vignettes' content validity using the scale-level content validity index.

RESULTS

The final content validation encompassed 2 Delphi rounds (phase 3), yielding a scale-level content validity index of 0.92 and 0.94 for the psychological and physical symptom vignettes, respectively. These results indicate excellent initial content validity.

CONCLUSIONS

The content of vignettes measuring individuals' knowledge of HF symptom self-management is valid based on the opinions of nurse experts. The vignettes offer a promising method to assess knowledge about HF self-care management without the pressure of disclosing individual patient practices.

Frailty in chronic heart failure: a multidimensional assessment of older patients undergoing cardiac rehabilitation

BACKGROUND

Chronic heart failure (CHF) is often associated with cognitive, psychological, and functional disorders. In addition, since patients suffering from this condition are often older adults, the presence of frailty could worsen the clinical situation.

METHODS

The present multicentric observational study aimed to investigate, through a multidimensional evaluation, the associations between clinical, functional, cognitive, psychological, and frailty variables of older (age ≥65) CHF inpatients undergoing cardiac rehabilitation and to identify the eventual independent predictors of the frailty status.

RESULTS

The study included 85 patients (mean age 73.88±5.84). The disease severity of the sample was moderate (left ventricular ejection fraction = 41.79±15.40). Among the patients, 32.94% had cognitive impairment, 12.94% and 14.11% reported moderate to severe anxious or depressive symptoms, respectively, and 34.12% were classified as frail (Clinical Frailty Scale [CFS] score ≥5). The CFS score showed a negative correlation with cognitive status (Addenbrooke's Cognitive Examination III [ACE III] [r=-0.48, P≤0.0001] and Frontal Assessment Battery [FAB] [r=-0.33, P=0.0001]) and functional status (Short Physical Performance Battery [SPPB] [r=-0.55, P≤0.0001] and Barthel Index [r=-0.52, P≤0.0001]), while showing a positive correlation with comorbidities (Cumulative Illness Rating Scale [CIRS] [r=0.40, P≤0.0001]). The stepwise regression analysis revealed that ACE III, SPPB, and CIRS were independent predictors of frailty status (CFS).

CONCLUSIONS

Frailty is an important variable that should be considered since it is linked with most of the variables that play a role in the management and outcomes of older CHF patients and, thus, its evaluation should be integrated into the usual assessment in cardiac rehabilitation.

Behavioral problems in children with unoperated rheumatic heart disease at national referral hospital in Ethiopia: an observational study

BACKGROUND

The behavioral disorder is characterized by a profound abnormality in an individual's cognition, emotion or behavior that reflects in psychological, biological or developmental dysfunction. Rheumatic heart disease (RHD) is a long-term sequel of single or recurrent acute rheumatic fever. Children with RHD are thought to be at increased risk for behavioral problems due to autoimmunity seen in pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS). Behavior disorder is not well studied among children with RHD. Hence, this study aimed to assess the pattern and predictors of behavioral problems among children with RHD enrolled in chronic care at a national cardiac referral Hospital.

METHODS

This cross-sectional study used a validated parental-reported Amharic Strengths and Difficulties Questionnaire (SDQ) to assess behavior problems. Children with RHD aged 6-17 years on chronic outpatient cardiac care at Tikur Anbessa Specialized Hospital, Ethiopia between February and May 2023 were included. Factors associated with behavior problems were assessed using logistic regression models.

RESULTS

The study included 166 children with a median age of 15 years [Interquartile range (IQR):13-17 years]. One-fourth of children, 24.7% (95% CI: 18.34-31.98), had behavioral problems. Of these, 46.4% (77) emotional, 35.5% (59) peer, 18.1% (30) conduct and 6.6% (11) hyperactivity problems were documented. Children who had good medication adherence, adjusted odds ratio AOR 0.29(95% CI: 0.09-0.94, P 0.040) and on New York Health Association (NYHA) class I, AOR 0.28(95% CI: 0.11-0.79, P 0.016) had lower odds for behavioral problems.

CONCLUSION

One-fourth of children with RHD had behavioral abnormalities. Medication adherence and NYHA predicted behavioral abnormality. Better physical symptom control was associated with fewer behavioral problems. Behavioral abnormalities should be considered and assessed among children with RHD. Further multi-center mixed studies are recommended to uncover the unseen behavioral problem and guide health policy action on modalities of integration of behavioral problems assessment tools in clinical care.

Status quo and factors influencing dyadic disease appraisal in chronic heart failure based on latent profile analysis in Northern Sichuan Province, China

PURPOSE

This study explored potential categories of dyadic disease appraisal differences among patients hospitalized with chronic heart failure (CHF) in China and analyzed the main factors influencing these categories.

METHODS

A survey was conducted using various tools and scales, including the Chinese version of the Memorial Heart Failure Symptom Appraisal Scale, Heart failure self-care index scale, Social Support Rating Scale, Zarit burden interview, and Self-rating anxiety scale. The data was collected from patients who were hospitalized with CHF in the cardiology department of one of two tertiary hospitals in Nanchong City, China. The dyadic disease appraisal categories were identified using latent profile analysis (LPA). Multiple logistic regression analysis was also employed to analyze the factors influencing the formation of potential categories of differences in dyadic disease appraisal in CHF patients.

RESULTS

A total of 262 pairs of hospitalized CHF patients and their caregivers participated in this study. The dyadic disease appraisal of CHF patients was potentially categorized as the "negative difference group" (28 individuals, 10.7%) and the "positive or convergence group" (234 persons, 89.3%). The results showed that the factors influencing the categorization of dyadic disease appraisal differences included the patient's social support, disease progression, and Caregivers anxiety level, burden, gender, educational attainment, and age (p < 0.05).

CONCLUSION

The study findings demonstrated heterogeneity between the two groups of CHF patients in the dyadic disease appraisal. Therefore, it is necessary to focus on patients who have a brief duration of illness and limited social support. Specifically, it is important to prioritize support for female caregivers who are 65 years or older, have lower levels of educational attainment, and experience a significant burden and anxiety. Regular implementation of support person-bilateral co-management strategies can effectively reduce differences in how the disease is perceived and enhance the overall well-being of both caregivers and patients.

The effects of psychiatric disorders on the risk of chronic heart failure: a univariable and multivariable Mendelian randomization study

Background

Substantial evidence suggests an association between psychiatric disorders and chronic heart failure. However, further investigation is needed to confirm the causal relationship between these psychiatric disorders and chronic heart failure. To address this, we evaluated the potential effects of five psychiatric disorders on chronic heart failure using two-sample Mendelian Randomization (MR).

Methods

We selected single nucleotide polymorphisms (SNPs) associated with chronic heart failure and five psychiatric disorders (Attention-Deficit Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), Major Depression, Bipolar Disorder and Schizophrenia (SCZ)). Univariable (UVMR) and multivariable two-sample Mendelian Randomization (MVMR) were employed to assess causality between these conditions. Ever smoked and alcohol consumption were controlled for mediating effects in the multivariable MR. The inverse variance weighting (IVW) and Wald ratio estimator methods served as the primary analytical methods for estimating potential causal effects. MR-Egger and weighted median analyses were also conducted to validate the results. Sensitivity analyses included the funnel plot, leave-one-out, and MR-Egger intercept tests. Additionally, potential mediators were investigated through risk factor analyses.

Results

Genetically predicted heart failure was significantly associated with ADHD (odds ratio (OR), 1.12; 95% CI, 1.04-1.20; p = 0.001), ASD (OR, 1.29; 95% CI, 1.07-1.56; p = 0.008), bipolar disorder (OR, 0.89; 95% CI, 0.83-0.96; p = 0.001), major depression (OR, 1.15; 95% CI, 1.03-1.29; p = 0.015), SCZ (OR, 1.04; 95% CI, 1.00-1.07; p = 0.024). Several risk factors for heart failure are implicated in the above cause-and-effect relationship, including ever smoked and alcohol consumption.

Conclusion

Our study demonstrated ADHD, ASD, SCZ and major depression may have a causal relationship with an increased risk of heart failure. In contrast, bipolar disorder was associated with a reduced risk of heart failure, which could potentially be mediated by ever smoked and alcohol consumption. Therefore, prevention strategies for heart failure should also incorporate mental health considerations, and vice versa.

Association between Psychiatric Disorders and the Incidence of Heart Failure in Women

BACKGROUND

Depression and anxiety occur more frequently in women and are associated with an increased risk of cardiovascular disease.

OBJECTIVES

Data on the association between these psychiatric conditions and the incidence of acute heart failure (HF) and how they influence heart failure outcomes in women are lacking. We investigated this potential relationship using data from the National Inpatient Sample.

METHODS

We used ICD-10 codes to extract encounters for acute heart failure and/or the acute exacerbation of chronic heart failure, anxiety, and depression from the discharge data of the NIS from 2019 to 2020. We compared baseline characteristics and length of stay (LOS), cost of care (COC) and acute HF by depression/anxiety status for males and females and employed regression models to assess the influence of these psychiatric conditions on the outcomes.

RESULTS

There were 6,394,136 encounters involving females, which represented 56.6% of the sample. The prevalence of depression and anxiety were 15.7% and 16.8%, respectively. Among females, the occurrence of acute CHF did not differ by depression or anxiety status. However, Takostubo cardiomyopathy was more prevalent in those with depression (0.3% vs. 0.2%, p = 0.003) and anxiety (0.3% vs. 0.2%, p = 0.03) compared to those without these conditions. Among those with depression, LOS was significantly longer (3 days IQR: 2-6, vs. 3 days IQR:2-5 days, p < 0.001). The COC was USD 1481 more in patients with depression. On the contrary, LOS and COC were significantly lower in those without anxiety.

CONCLUSIONS

Depression was associated with an increased LOS among both men and women and an increased cost of care among women. Anxiety was associated with a decreased LOS and cost of care among women, which may be related to an increased rate of against medical advice (AMA) discharges among this population. Further research is necessary to identify optimal management strategies for depression and anxiety among patients hospitalized with HF.

In silico discovery of potential sodium-glucose cotransporter-2 inhibitors from natural products for treatment of heart failure via molecular docking and molecular dynamics simulation approach

Heart failure (HF) is the end stage of cardiovascular disease. Because of its complex condition and poor prognosis, HF has become an important public health problem in the world. Sodium-glucose cotransporter-2 (SGLT2) is a member of the glucose transporter family. Recently, SGLT2 inhibitors have been applied to treat HF. In this study, the main aim was to discover natural SGLT2 inhibitor from Chinese herbs through docking-based virtual screening. Totally 113 natural compounds of potential SGLT2 inhibitor were identified, which displayed docking affinity higher than six approved inhibitors (dapagliflozin (IC50 = 4.9 nM), canagliflozin (IC50 = 4.4 nM 6.7), ipragliflozin (IC50 = 7.4 nM), empagliflozin (IC50 = 3.1 nM), tofogliflozin (IC50 = 4 nM) and luseogliflozin (IC50 = 2.3 nM)) through docking-based virtual screening. Then, the top three hits (ZINC70455591, ZINC85594065 and ZINC14588133) and six known inhibitors were selected for molecular dynamics simulation and the binding free energy calculation using molecular mechanics Poisson-Boltzmann surface area to demonstrate the stability and affinity of docked complexes. These results pointed out that the three docked complexes were stabilized and the chosen compounds were tightly adhering to the binding site of SGLT2. Besides, pharmacokinetic properties of the selected compounds showed those natural compounds may be potential drug candidates. This study may be contributed to further in vitro and in vivo validation and the development of novel SGLT2 inhibitor for treating HF.Communicated by Ramaswamy H. Sarma.
