Association Between Poorer Cognitive Function and Reduced Objectively Monitored Medication Adherence in Patients With Heart Failure

Personality and cognitive errors in the Healthy Aging in Neighborhoods of Diversity across the Life Span study

This study examines the association between personality and cognitive errors in the Healthy Aging in Neighborhoods of Diversity across the Life Span study, a sample diverse across race (Black, White) and SES (above, below 125% of the federal poverty line). Participants (N=1,062) completed a comprehensive personality questionnaire and were administered a brief mental status screener of cognitive errors. Higher neuroticism was associated with more cognitive errors, whereas higher openness and conscientiousness were associated with fewer errors. These associations were independent of age, sex, race, poverty status, and education and were generally not moderated by these factors. These findings support the associations between personality and cognition across race and SES.

Cognitive impairment in heart failure patients: association with abnormal circadian blood pressure rhythm: a review from the HOPE Asia Network

Cognitive impairment (CI) is frequently a comorbid condition in heart failure (HF) patients, and is associated with increased cardiovascular events and death. Numerous factors contribute to CI in HF patients. Decreased cerebral blood flow, inflammation, and activation of neurohumoral factors are all thought to be factors that exacerbate CI. Hypoperfusion of the brain due to decreased systemic blood flow, cerebral venous congestion, and atherosclerosis are the main mechanism of CI in HF patients. Abnormal circadian BP rhythm is one of the other conditions associated with CI. The conditions in which BP does not decrease sufficiently or increases during the night are called non-dipper or riser BP patterns. Abnormal circadian BP rhythm worsens CI in HF patients through cerebral congestion during sleep and atherosclerosis due to pressure overload. Interventions for CI in HF patients include treatment for HF itself using cardiovascular drugs, and treatment for fluid retention, one of the causes of abnormal circadian rhythms. Proposed pathways of cognitive impairment in heart failure through abnormal circadian blood pressure rhythm.

Heart failure with comorbid dementia: Association with clinical characteristics and outcomes

BACKGROUND

Heart failure (HF) and dementia both have profound effects on function and mortality in older persons. However, we have limited knowledge about the impact of co-occurring HF and dementia. Our goal was to understand how often persons with HF have dementia and the impact of their co-occurrence.

METHODS

Retrospective analysis of participants (age > 65) in the 2015 wave of the nationally representative Health and Aging Trends Study (NHATS) with linkage to Medicare claims. 912 participants with HF (45% older than 80, 51% women) using Medicare claims. We used the validated NHATS dementia algorithm to identify those with probable dementia. Outcomes of interest included the need for help with activities of daily living (ADLs) and instrumental activities of daily living (IADLs) at baseline, functional decline, hospitalization over 1 year, and mortality over 2-years. Baseline functional status, functional decline, and hospitalization were compared using adjusted logistic regression, mortality was analyzed using adjusted Cox regression models adjusted for demographics, socio-economic status, baseline health, and baseline functional status.

RESULTS

200 (21%) of the participants with HF also had dementia. For each I/ADL, patients with both HF and dementia were more likely to need help than those with HF without dementia. 71.8% of participants with HF and dementia needed help with medications versus 16.6% with HF without dementia (p < 0.001). Having HF and dementia was associated with an increased risk of requiring help with additional ADLs after one year (aOR = 2.69, 95% CI 1.53, 4.73). Participants with HF and dementia had an increased risk of being hospitalized within one year (aOR = 2.02 95% CI 1.16, 3.54), or dying within two years (aHR = 1.52 95% CI 1.03, 2.26).

CONCLUSIONS

One-fifth of persons over age 65 with HF also have comorbid dementia. Co-occurring HF and dementia markedly increase functional impairment and subsequent ADL decline, hospitalization, and death. These results highlight the need for physician awareness for signs of dementia, and appropriate adjustments in the management of HF.

Prevalence and trajectories of subjective cognitive complaints and implications for patient outcomes: A prospective study of haemodialysis patients

OBJECTIVES

Cognitive impairment is common in haemodialysis patients and is associated with increased hospitalization and mortality. However, subjective cognitive complaints (SCCs), the self-experienced difficulties in everyday cognitive activities, remain poorly understood. This study examined the prevalence and course of SCCs in haemodialysis patients and its longitudinal associations with sociodemographic, clinical and patient-reported variables.

DESIGN

Observational prospective study with baseline and 12-month follow-up assessment.

METHODS

Based on a validated cut-off point on the Kidney Disease Quality of Life Cognitive Function subscale, haemodialysis patients (N = 159; 40.3% female, mean age 53.62) were classified into cognitive complaint trajectories: (1) resilient (60.4%; no/low SCCs throughout); (2) persistent (8.8%; stable high SCCs); (3) deterioration (17.6%; from no/low to high SCCs); and (4) recovery (13.2%; from high to no/low SCCs). Sociodemographic/clinical characteristics, self-efficacy, self-management skills, adherence, mood and biochemical assays were measured at both assessments and compared among trajectories using mixed ANOVAs.

RESULTS

Interaction effects indicated significant improvements in the recovery group in clinical outcomes (i.e., decreased phosphorus and calcium-phosphorus product), self-efficacy and mood over time. Group effects indicated significantly poorer self-efficacy, self-management skills and adherence in the persistent group than other trajectories across both assessments. None of the sociodemographic/clinical characteristics was associated with SCC trajectories.

CONCLUSIONS

The extent of SCCs vary over time across haemodialysis patients. Routine screening of SCCs in dialysis settings may help identifying patients at risk of poor self-management and worse prognosis. Strategies that compensate for cognitive lapses may mitigate the perceived cognitive burden of this population.

Sleep Quality, Metabolic Function, Physical Activity, and Neurocognition Among Individuals with Resistant Hypertension

BACKGROUND

Resistant hypertension (RH) is a major risk factor for stroke, cognitive decline, and dementia. Sleep quality is increasingly suggested to play an important role linking RH to cognitive outcomes, although the mechanisms linking sleep quality to poor cognitive function have yet to be fully delineated.

OBJECTIVE

To delineate biobehavioral mechanisms linking sleep quality, metabolic function, and cognitive function among 140 overweight/obese adults with RH in the TRIUMPH clinical trial.

METHODS

Sleep quality was indexed using actigraphy measures of sleep quality and sleep fragmentation, as well as self-reported sleep quality from the Pittsburgh Sleep Quality Index (PSQI). Cognitive function was assessed using a 45-minute battery assessing executive function, processing speed, and memory. Participants were randomized to a cardiac rehabilitation-based lifestyle program (C-LIFE) or a standardized education and physician advice condition (SEPA) for 4 months.

RESULTS

Better sleep quality at baseline was associated with better executive function (B = 0.18 p = 0.027), as well as greater fitness (B = 0.27, p = 0.007) and lower HBA1c (B = -0.25, p = 0.010). Cross-sectional analyses revealed that the sleep quality executive function association was mediated by HBA1c (B = 0.71 [0.05, 2.05]). C-LIFE improved sleep quality (-1.1 [-1.5, -0.6] versus+-0.1 [-0.8, 0.7]) and actigraphy steps (+922 [529, 1316] versus+56 [-548, 661]), with actigraphy mediating improvements in executive function (B = 0.40 [0.02, 1.07]).

CONCLUSION

Better metabolic function and improved physical activity patterns levels play important roles linking sleep quality and executive function in RH.

Management and outcomes of patients with chest pain and psychiatric disorders in the era of high-sensitivity cardiac troponins

BACKGROUND

The management of patients with psychiatric disease and chest pain in the emergency department (ED) in the era of high-sensitivity cardiac troponin assays is unexplored.

OBJECTIVES

To investigate differences in management and outcomes comparing patients with versus without psychiatric disorders who present with chest pain in the ED.

METHODS

All visits to seven different EDs in Sweden from 9 December 2010 to 31 December 2016 by patients with chest pain were included. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate differences in clinical management. Hazard ratios with 95% CIs were used for comparisons of all-cause mortality and risk of cardiovascular events.

RESULTS

Altogether, 216,653 visits were identified, of which 40,054 (18%) occurred in patients with psychiatric disorders. The risk of a myocardial infarction (MI) was reduced almost by half in patients with an affective (OR 0.63; 95% CI: 0.59-0.68) or psychotic disorder (OR 0.57; 95% CI: 0.47-0.70). These patients were less likely to be treated with any cardiovascular medication or to undergo percutaneous coronary intervention. Contrastingly, patients with psychiatric disease had a 1.8- to 2.6-fold increased risk of being diagnosed with an MI registered after the index visit but within 30 days.

CONCLUSIONS

Patients with psychiatric disease and chest pain undergo less intense investigation and are less likely to receive cardiovascular medications compared with patients without psychiatric disease, even in the presence of myocardial injury. In addition, they experience a higher risk of being diagnosed with an MI within 30 days after a visit with no MI.

Medication Discussions With Patients With Cardiovascular Disease in the Emergency Department: An Opportunity for Emergency Nurses to Engage Patients to Support Medication Reconciliation

INTRODUCTION

This study aimed to investigate the level of patient involvement in medication reconciliation processes and factors associated with that involvement in patients with cardiovascular disease presenting to the emergency department.

METHODS

An observational and cross-sectional design was used. Patients with cardiovascular disease presenting to the adult emergency department of an academic medical center completed a structured survey inclusive of patient demographics and measures related to the study concepts. Data abstracted from the electronic health record included the patient's medical history and emergency department visit data. Our multivariable model adjusted for age, gender, education, difficulty paying bills, health status, numeracy, health literacy, and medication knowledge and evaluated patient involvement in medication discussions as an outcome.

RESULTS

Participants' (N = 93) median age was 59 years (interquartile range 51-67), 80.6% were white, 96.8% were not Hispanic, and 49.5% were married or living with a partner. Approximately 41% reported being employed and 36.9% reported an annual household income of <$25,000. Almost half (n = 44, 47.3%) reported difficulty paying monthly bills. Patients reported moderate medication knowledge (median 3.8, interquartile range 3.4-4.2) and perceived involvement in their care (41.8 [SD = 9.1]). After controlling for patient characteristics, only difficulty paying monthly bills (b = 0.36, P = .005) and medication knowledge (b = 0.30, P = .009) were associated with involvement in medication discussions.

DISCUSSION

Some patients presenting to the emergency department demonstrated moderate medication knowledge and involvement in medication discussions, but more work is needed to engage patients.

Subjective Cognition is Related to Patient-Reported Symptom Distress and Work Productivity Among Liver Transplant Recipients

Cognitive decline may prevent liver transplant (LT) recipients from staying healthy and independent. This study examined associations of objective and subjective, rated by LT recipients and caregivers, cognitive decline with patient-reported physical and psychological symptom distress, ability to perform household tasks, and workplace productivity among LT recipients. Sixty pairs of LT recipients and caregivers participated in this cross-sectional study. Subjective cognition was measured by the Everyday Cognition. Objective cognition was assessed with four cognitive tests, including the Repeatable Battery for the Assessment of Neuropsychological Status. Patient-reported outcomes were assessed with the Rotterdam Symptom Checklist-Modified, Profile of Mood States-Short Form, Creative Therapy Consultants Homemaking Assessment, and Work Limitations Questionnaire. Linear regression analyses related objective and subjective cognition to the patient-reported outcomes. While objective cognitive decline was not associated with any patient-reported outcomes, subjective cognitive decline was significantly associated with the outcomes. Higher LT recipient self-rated cognitive decline was associated with higher physical symptom distress ( β = 0.30, p = 0.006) and workplace productivity loss ( β = 14.85, p < 0.0001). Higher caregiver-rated cognitive decline was associated with lower household tasks performance ( β = -18.55, p = 0.015). Findings suggest to consider subjective cognition when developing an individualized post-transplant care plan.

Short term effect of sacubitril/valsartan on comprehensive geriatric assessment in chronic heart failure: a real life analysis

Sacubitril/Valsartan (Sac-Val) has improved clinical prognosis in patients affected by heart failure (HF) with reduced ejection fraction (HFrEF). Comorbidities have a crucial impact on clinical presentation and prognosis in HF patients. Cognitive impairment (CoI) and Depression are a very common comorbidity in patients with HF and is widely recognized as a specific determinant of chronic disability, and HF patients with poor physical functional performance in Short physical performance battery (SPPB) showed a worse prognosis. The aim of the present study was to evaluate the potential effects of Sac-Val on functional, humoral, and cognitive aspects, evaluated by performing comprehensive geriatric assessment (CGA), in a cohort of elderly HFrEF. We studied 61 patients (51 men and 10 women, mean age 76.4 ± 5.1 years) suffering from HFrEF. After 6 months follow-up, we observed a significant improvement in humoral and functional parameters of CGA, renal function, NTpro-BNP levels and echocardiographic parameters. In the whole population, multivariate analysis shows that changes of Cardiac Index, NT-proBNP and Respiratory rate contributed for 26.0%, 9.7% and 4.8% to GDS variability, respectively, and the whole model accounted for a 41.1% of GDS variation; moreover changes of Global longitudinal strain, estimated glomerular filtration rate, Cardiac Index and BMI contributed for 23.9%, 11.7%, 5.4% and 4.0% to SPPB variability, respectively, and the whole model accounted for a 45% of SPPB variation. This represents the first real-world study carried out in an elderly population suffering from chronic HFrEF with numerous comorbidities, in which treatment with Sac-Val for 6 months induced important improvements in clinical, humoral, hemodynamic, and functional outcomes, without adverse effects on cognitive performance.

Structural Relationships Between Cognitive Function, Depressive Symptoms, Self-Care Confidence, and Maintenance in Patients With Heart Failure

Introduction

In order to promote self-care maintenance behavior in patients with heart failure (HF), it is necessary to identify the direct and indirect effects of major latent variables.

Objective

This study aimed to identify structural relationships between different domains of cognitive function, depression and self-care confidence, and self-care maintenance.

Methods

This descriptive study involved a secondary analysis using data of 201 patients with HF from two observational studies in three hospitals in Korea. The structural equation model using AMOS version 24.0 was constructed to assess the relationships among the variables. The Seoul Neuropsychological Screening Battery was used to assess global cognition, immediate/delayed memory, and executive function, and the Self-Care of HF Index v.6.2. was used for self-care confidence and maintenance.

Results

Self-care maintenance was affected by memory function with a significant direct effect (β=.43, p = .006), as well as self-care confidence (β=.70, p < .001). Memory function and global function indirectly affected self-care maintenance through self-care confidence (β = -.37, p = .002; β = .14, p = .030). Depressive symptoms also had an indirect effect through self-care confidence on self-care maintenance (β = -.21, p = .005).

Conclusion

This study confirmed that it is important to increase self-care confidence through supportive care and to maintain memory function for maintaining self-care in the chronic course of HF patients. In particular, this study suggests that it is necessary to perform periodic memory check-ups for chronic HF patients on an outpatient basis, and counseling and education are needed to improve memory and increase confidence in self-care.

The role of subjective cognitive complaints in self-management among haemodialysis patients: a cross-sectional study

Background

Subjective cognitive complaints refer to self-experienced difficulties with everyday cognitive tasks. Although there has been a fair amount of research on cognitive impairments and cognitive complaints in end-stage renal disease, the practical implications of these complaints remain unclear. The current study aims to examine the associations of cognitive complaints with sociodemographic and clinical variables, mood, as well as key patient-reported outcomes, i.e., self-efficacy, self-management skills, and treatment adherence.

Methods

A total of 305 haemodialysis patients (mean age = 53.97 years, 42.6% female) completed the Kidney Disease Quality of Life Cognitive Function subscale, a brief measure of cognitive complaints. The recommended cut-off point of 60 was used to identify probable cognitive impairment. Measures of self-efficacy, self-management skills (i.e., symptom coping, health monitoring, health service navigation), treatment adherence, and mood symptoms were also administered. Between-group comparisons and correlational analyses were performed to examine associations of cognitive complaints with sociodemographic, clinical, and health behaviour variables. Mediation analyses were also conducted to investigate the mediating role of self-efficacy on the relationship between cognitive complaints and treatment adherence.

Results

Nearly a quarter (23.0%) of haemodialysis patients reported cognitive complaints indicative of clinical impairments. Risk of probable impairments was higher for patients with hypertension, diabetes, those diagnosed with end-stage renal disease at an older age, and those with shorter time on dialysis. Subjective cognitive complaints (both rates of probable impairments as per cut-off and continuous scores) were significantly associated with lower disease and treatment self-efficacy, poorer self-management skills, lower treatment adherence, as well as higher symptoms of distress. Mediation analysis indicated that treatment self-efficacy mediated the relationship between cognitive complaints and treatment adherence.

Conclusions

The current study demonstrated the clinical characteristics of haemodialysis patients who report cognitive complaints indicative of probable cognitive impairments and showed the associations of these complaints with self-management outcomes. Future studies should adopt more comprehensive measures of cognitive complaints and longitudinal designs to confirm the current findings.

Mind Your Heart: Exploring Feasibility, Acceptability, and Preliminary Effects of Phone-Delivered Mindfulness Training on Medication Adherence in Outpatients With Chronic Heart Failure

BACKGROUND

Mindfulness training (MT) may promote medication adherence in outpatients with heart failure.

OBJECTIVE

The aims of this study were to determine the feasibility and acceptability of MT (primary outcomes) and explore effects on medication adherence, functional capacity, cognitive function, depression, and mindfulness skills (secondary outcomes).

METHODS

In this pre/post-design study, participants received a 30-minute phone-delivered MT session weekly for 8 weeks.

RESULTS

We enrolled 33 outpatients (32% women; 69.7 White; mean age, 60.3 years). Retention was 100%, and session attendance was 91%. Overall, participants (97%) rated MT as enjoyable. Objectively assessed ( P < .05) adherence decreased post intervention, whereas improvements were noted in functional capacity ( P = .05), mindfulness ( P < .05), and cognitive function (reaching significance for Flanker scores).

CONCLUSIONS

Phone-delivered MT was feasible and acceptable. Whereas no improvements were noted in medication adherence and depression, cognitive function, functional capacity, and mindfulness levels increased post intervention, suggesting MT may have beneficial effects in outpatients with heart failure.

Tablet-Based Assessment of Cognitive Function Among Heart Failure Patients

BACKGROUND

Cognitive impairment accompanying heart failure (HF) is an additional HF comorbidity, which may potentially affect the patient's self-care and compliance. We aimed to assess cognitive function (CF) using an application with games created as a cognitive training tool for children and adults, applied using a tablet, and to compare the results obtained by HF patients with the results obtained by healthy age-matched controls.

METHODS

A total of 69 individuals (49 HF patients and 10 healthy controls) were assessed using 4 games dedicated to measuring cognitive skills as well as questionnaires regarding their socioeconomic status. Additionally, HF patients were asked about their quality of life and anxiety and depression.

RESULTS

HF patients demonstrated worse results in each game assessing their cognitive functions as compared to the healthy age-matched controls, which is consistent with the previous studies on CF in HF. We have also noticed interesting patterns of relations between CF and sleep and education.

CONCLUSIONS

We have demonstrated that information and communication technology devices can be successfully applied as feasible tools for cognitive assessment in the HF population. This is important as tablet-based CF assessment can be done on a large population without the involvement of trained personnel.

Cognitive Dysfunction in Heart Failure: Pathophysiology and Implications for Patient Management

PURPOSE OF REVIEW

There is increasing recognition of the prevalence and impact of cognitive dysfunction (CD) in heart failure (HF) patients. This contemporary review appraises the evidence for epidemiological association, direct pathophysiological links and emerging pharmacological and non-pharmacological interventions. Furthermore, we present evidence for care models that aim to mitigate the morbidity and poor quality of life associated with these dual processes and propose future work to improve outcomes.

RECENT FINDINGS

CD disproportionately affects heart failure patients, even accounting for known comorbid risk factors, and this may extend to subclinical left ventricular dysfunction. Neuroimaging studies now provide evidence of anatomical and functional differences which support previously postulated mechanisms of reduced cerebral blood flow, micro-embolism and systemic inflammation. Interventions such as multidisciplinary ambulatory HF care, education and memory training improve HF outcomes perhaps to a greater degree in those with comorbid CD. Additionally, optimisation of standard heart failure care (cardiac rehabilitation, pharmacological and device therapy) may lead to additional cognitive benefits. Epidemiological, neuroimaging and intervention studies provide evidence for the causal association between HF and CD, although evidence for Alzheimer's dementia is less certain. Specific reporting of cognitive outcomes in HF trials and evaluation of targeted interventions is required to further guide care provision.

Cognitive Impairment in Heart Failure—A Review

Simple Summary

Compared to the general population, patients with heart failure have reduced cognition and increased dementia risk. Brain changes have been observed in these individuals, including reduced brain volumes and abnormal areas suggestive of ischaemia (lack of blood and hence oxygen supply to tissues). Patients with heart failure who have cognitive impairment have poorer self-care and are at increased risk of rehospitalisation and death. Causes of cognitive impairment in heart failure have been suggested, including reduced blood supply to the brain, inflammatory processes, protein abnormalities and thromboembolic disease (formation of blood clots which may travel to the brain and impede blood flow). In this article, we discuss these potential causes linking heart failure and cognitive impairment, and discuss the recognition and management of cognitive impairment in patients with heart failure.

Abstract

Cognitive impairment (CI) is common in heart failure (HF). Patients with HF demonstrate reduced global cognition as well as deficits in multiple cognitive domains compared to controls. Degree of CI may be related to HF severity. HF has also been associated with an increased risk of dementia. Anatomical brain changes have been observed in patients with HF, including grey matter atrophy and increased white matter lesions. Patients with HF and CI have poorer functional independence and self-care, more frequent rehospitalisations as well as increased mortality. Pathophysiological pathways linking HF and CI have been proposed, including cerebral hypoperfusion and impaired cerebrovascular autoregulation, systemic inflammation, proteotoxicity and thromboembolic disease. However, these mechanisms are poorly understood. We conducted a search on MEDLINE, Embase and Scopus for original research exploring the connection between HF and CI. We then reviewed the relevant literature and discuss the associations between HF and CI, the patterns of brain injury in HF and their potential mechanisms, as well as the recognition and management of CI in patients with HF.

Psychosocial management in cardiac rehabilitation: Current practices, recommendations, and opportunities

Psychosocial management is a core component of outpatient Phase-II cardiac rehabilitation (CR) and includes psychosocial assessment, providing interventions, measuring outcomes, and care coordination. Psychosocial management contributes to the effectiveness of comprehensive CR, but the implementation is not always consistent or clearly described in the literature, in part due to the availability of behavioral health specialists. Patients in CR have many psychosocial needs including anxiety, depression, substance use disorders, sleep problems, psychosocial stress, and cognitive impairment. Behavioral considerations are inherent in many other aspects of CR,such as participation in CR, health behaviors, adherence, and tobacco cessation. Evaluation, or psychosocial assessment, should identify significant issues, record related medications, and incorporate findings in the individual treatment plan. Some patients require further evaluation and treatment by a qualified behavioral health specialist. Psychosocial interventions provided to all patients include patient education, counseling, stress-management, a supportive environment, and exercise. Measuring outcomes entails repeating the psychosocial assessment when patients finish CR and documenting changes. Coordinating care requires understanding available local mental health infrastructure and procedures for making referrals, and may entail identifying additional resources. Interventions provided concurrently with CR to a subset of patients with more extensive needs are typically pharmacotherapy, psychotherapy, or addictions counseling, which are beyond the scope of practice for most CR professionals. The way psychosocial management is implemented suggests clinical and research opportunities. For example, the combined effects of antidepressants and CR on depression and anxiety are not known. A prominent clinical opportunity is to fully implement psychosocial assessment, as required by statute and the core components. This could involve referring patients for whom clinically significant psychosocial concerns are identified during the evaluation for a more thorough assessment by a behavioral health specialist using an appropriate billing model. A research priority is a contemporary description of behavioral health services available to CR programs, including how psychosocial management is implemented. As delivery of CR comes to include more alternative models (e.g., home-based), research is needed on how that affects the delivery of psychosocial management. Increased use of telehealth may broaden clinical opportunities for psychosocial management.

The Role of Depression on Treatment Adherence in Patients with Heart Failure-a Systematic Review of the Literature

INTRODUCTION

Although poor medication adherence is considered an impacting risk factor for worsening heart failure (HF) outcomes, adherence rates in HF patients continue to be considerably low. To improve this condition, several studies investigated the impact of many determinants on medication adherence; however, few authors explored the role of depression on it.

PURPOSE OF REVIEW

The purpose of this systematic review was to explore the association between depressive symptoms and medication adherence in HF patients. In particular, the research question was is depression a barrier to medication adherence in HF patients?

METHODS

A systematic review of quantitative analysis studies was undertaken. Six electronic databases were searched between the end of October and March 2022. Thirty-one trials were included, all of them assessed depression, adherence to medication, and their possible relationship.

RESULTS

As was intended, findings showed that the impact of a mild to moderate level of depression was significant on adherence to treatment in HF patients. However, many other risk factors emerged, like family support and health practices (es. low sodium diet).

CONCLUSION

The detection of depression in the setting of HF should be crucial to HF patients' physical health and quality of life. Future research should take depression into account, exploring this area through self-report and qualitative interview as well.

Association between cognitive function and self-reported antihypertensive medication adherence among middle-aged and older hypertensive women

DESIGN

This study applied a cross-sectional, descriptive correlational design.

AIMS AND OBJECTIVES

The purpose of the study was to examine the relationship between cognitive function and self-reported antihypertensive medication adherence in middle-aged and older hypertensive women.

BACKGROUND

Although medication adherence is an essential key for preventing complications from hypertension, poor medication adherence is common among middle-aged and older hypertensive women. Taking medications involves a cognitive process. Little is known about the contribution of cognitive function to adherence to antihypertensive medication in middle-aged and older women.

METHODS

This study used a convenience sample of 137 women aged ≥50 years recruited from a medical centre in southern Taiwan. Participants completed a survey of demographic and clinical information and self-reported medication adherence, and received cognitive function tests. Hierarchical regression analyses were used to evaluate the association between cognitive function and medication adherence. This study followed the STROBE guidelines.

RESULTS

More than one-fourth of the women (27%) reported poor adherence. Women with poor adherence appeared to have a significantly lower memory than women with good adherence. Memory was positively associated with antihypertensive medication adherence after controlling for age, blood pressure and duration of hypertension. Working memory, executive function and psychomotor speed were not significantly related to antihypertensive medication adherence.

CONCLUSIONS

Reduced memory function was associated with poorer antihypertensive medication adherence among middle-aged and older women. Middle-aged and older women with hypertension and poor memory performance are at risk of poor medication adherence. Future prospective studies examining the causal relationship between cognitive function and antihypertensive medication adherence are warranted.

RELEVANCE TO CLINICAL PRACTICE

Nurses could evaluate the memory of middle-aged and older hypertensive women when assessing antihypertensive medication adherence in clinical practice and provide relevant interventions.

Cardiovascular care of older adults

Age is an independent risk factor for cardiovascular disease. With the accelerated growth of the population of older adults, geriatric and cardiac care are becoming increasingly entwined. Although cardiovascular disease in younger adults often occurs as an isolated problem, it is more likely to occur in combination with clinical challenges related to age in older patients. Management of cardiovascular disease is transmuted by the context of multimorbidity, frailty, polypharmacy, cognitive dysfunction, functional decline, and other complexities of age. This means that additional insight and skills are needed to manage a broader range of relevant problems in older patients with cardiovascular disease. This review covers geriatric conditions that are relevant when treating older adults with cardiovascular disease, particularly management considerations. Traditional practice guidelines are generally well suited for robust older adults, but many others benefit from a relatively more personalized therapeutic approach that allows for a range of medical circumstances and idiosyncratic goals of care. This requires weighing of risks and benefits amidst the patient's aggregate clinical status and the ability to communicate effectively about this with patients and, where appropriate, their care givers in a process of shared decision making. Such a personalized approach can be particularly gratifying, as it provides opportunities to optimize an older patient's function and quality of life at a time in life when these often become foremost therapeutic priorities.

Compliance with Telemonitoring in Heart Failure. Are Study Findings Representative of Reality?: A Narrative Literature Review

Introduction: Telemonitoring technologies enable medical teams to remotely manage outpatients with heart failure (HF) and reduce their risk of HF-related hospitalizations. However, noncompliance threatens the effectiveness of these approaches. This review aims to identify whether patients who are less likely or unable to comply with telemonitoring and their instructions for use are represented by interventional telemonitoring studies, and if their exclusion from studies is resulting in study findings not representative of clinical reality. Methods: A narrative literature review was conducted to identify interventional telemonitoring studies reporting compliance rates for HF patients. A search of PubMed and Medline databases identified eligible studies published between January 2000 and June 2021. Results: Twenty-five (n = 25) eligible studies with an interventional study design were identified. Reported compliance with telemonitoring ranged between 37% and 98.5%; however, 72% of studies reported good or medium compliance. A majority (76%) of studies had exclusion/inclusion criteria favoring the enrollment of patients who may be more likely to comply with telemonitoring and their instructions for use. Forty percent of studies had a sample with a mean or median age of <65 years. Participants were more likely to be male (majority in 92% of studies) and white (majority in 78% of studies that reported ethnicity). Conclusion: Compliance rates reported by current studies are unlikely to be generalizable to the wider HF population, particularly patients who are less likely or unable to comply with telemonitoring. Studies are therefore likely overestimating compliance rates. Future innovation should focus on designing "low compliance" solutions that require minimal engagement from users and future studies should aim to recruit a more generalizable cohort of patients. To achieve a more standardized metric of compliance, studies should report compliance (however defined) achieved by the 25th, 50th, and 75th percentile of all patients enrolled.

Adherence to CPAP therapy for sleep apnea in patients aged over 70 years old

Purpose

Adherence to continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) syndrome has not been established in patients over 70 years of age, whereas several studies have reported adherence below that age. This trial was designed to address this evidence gap.

Methods

Consecutive senior (> 70 years) patients with OSA, mean respiratory event index (REI) 34/h, body mass index (BMI) 31 kg/m², and junior (< 50 years) patients (REI 37/h, BMI 31 kg/m²) were included.

Results

At year follow-up among 72 senior patients (35 women) and 71 junior patients (17 women), there was no difference in the percentage of patients abandoning CPAP (senior 47% vs. junior 43%) or in CPAP daily use (4:53 ± 2:44 hh:min vs. 4:23 ± 3:00 hh:min).

Conclusions

CPAP adherence in senior patients with OSA was not poorer than that of a younger group of OSA patients. Advanced age should not be an obstacle to CPAP initiation.

Performances on the Montreal Cognitive Assessment Along the Cardiovascular Disease Continuum

 

Cardiovascular diseases involve a continuum starting with risk factors, which can progress to coronary heart disease and eventually, to heart failure. Cognitive impairment (CI) is observed as early as cardiovascular risk factors, and in up to 50% of patients with heart failure. Because CI in cardiovascular disease is linked to poorer clinical outcomes, early detection is essential. The Montreal Cognitive Assessment (MoCA) is a screening tool widely used in clinical setting. To date, little is known about MoCA scores along the cardiovascular disease continuum.

OBJECTIVE

This study compared performances of different cardiovascular disease profiles on the MoCA and its subscores.

METHOD

Eighty participants (>50 years) from two studies conducted at the Montreal Heart Institute were separated into four groups: low cardiovascular risk factors (<2), high cardiovascular risk factors (>2), coronary heart disease, and stable heart failure. ANCOVAs were performed on the total score and on subscores, with sex, age, and education as covariates.

RESULTS

Group differences were observed on the MoCA total score (heart failure < low cardiovascular risk), verbal fluency (heart failure < low cardiovascular risk), memory (coronary heart disease < low cardiovascular risk), and orientation (coronary heart disease < low and high cardiovascular risk) subscores.

CONCLUSION

Results suggest that the MoCA, particularly verbal fluency and memory subscores, can detect cognitive changes in later stages of the cardiovascular disease continuum, such as heart failure. Detecting cognitive changes earlier on the cardiovascular disease continuum may require more in depth neuropsychological assessments.

Psychosocial considerations in the assessment of hand transplant candidates: A single-center experience and brief literature review

Vascularized composite allograft, including hand transplantation (HT), has gained wider usage as a reconstructive treatment over the past 30 years. HT recipients face unique psychosocial challenges compared to their solid organ and/or bone marrow transplant counterparts. Accordingly, the psychosocial evaluation among HT candidates continues to evolve, leaving a lack of consensus as to the critical psychosocial domains and psychometric testing instruments to help evaluate individuals considering HT. The present manuscript describes the psychosocial evaluation process within the Duke HT program, which been contacted by 80 potential candidates since 2014. The Duke HT evaluation process incorporates a comprehensive psychosocial assessment within domains including personality, cognitive function, mood, behavioral adherence, social support, and substance use history, among others. Our experience underscores the potential utility of collecting thorough psychosocial evaluations, supplemented by psychometric test data, to comprehensively assess potential HT candidates.

Insights from Monitoring Aspirin Adherence: A Medication Adherence Cascade Tool

BACKGROUND

Adherence to recommended medications is a key issue in the care of patients with cardiovascular disease (CVD) and barriers to adherence are well established during the medication adherence cascade, the processes of prescribing, obtaining, taking, and maintaining medication use. Aspirin avoids many of the barriers in the medication adherence cascade as it does not require a prescription (prescribing) and is inexpensive, easily accessible (obtaining), prescribed once-daily (taking) as an over-the-counter medication and is generally perceived by patients as safe (maintaining). The purpose of this paper is to report aspirin adherence and propose the Medication Adherence Cascade Tool to assist clinicians to consider all aspects of medication adherence.

METHODS

Adherence to aspirin was monitored with an electronic pillbox. Frequency analysis, independent T-tests, and ANOVA were completed on 151 patients with underlying heart failure who were prescribed aspirin within a larger parent study. Chi-square tests were completed to assess differences in baseline demographic characteristics.

FINDINGS

Mean aspirin adherence was 82.2% overall, with 11.9% of sample with adherence 50%, 18.5% with adherence 50-80%, and 69.5% with adherence ≥80%. Greater adherence was observed in self-identified White as compared to Black patients (84.47% vs 73.53%; p = 0.014), and patients ≥70 years of age compared to <70 years (87.00% vs 77.49%; p = 0.009).

INTERPRETATION

Aspirin adherence was suboptimal despite the fact that it addresses most of the barriers on the medication adherence cascade (ie, relatively easy access, low cost, and low risk). A Medication Adherence Cascade Tool (MACT) is proposed as a clinical guide to facilitate patient-provider co-production of strategies to address medication adherence. The tool can assist patients and providers to co-produce adherence to achieve optimal medication benefits.

Arterial Stiffness, Cognitive Dysfunction and Adherence to Antihypertensive Agents. Is there a Link to Hypertensive Patients?

The incidence of hypertension (HTN) and its cardiovascular (CV) complications are increasing throughout the world. Blood pressure (BP) control remains unsatisfactory worldwide. Medical inertia and poor adherence to treatment are among the factors that can partially explain, why BP control rate remains low. The introduction of a method for measuring the degree of adherence to a given medication is now a prerequisite. Complex treatment regimes, inadequate tolerance and frequent replacements of pharmaceutical formulations are the most common causes of poor adherence. In contrast, the use of stable combinations of antihypertensive drugs leads to improved patient adherence. We aim to review the relationships between arterial stiffness, cognitive function and adherence to medication in patients with HTN. Large artery stiffening can lead to HTN. In turn, arterial stiffness induced by HTN is associated with an increased CV and stroke risk. In addition, HTN can induce disorders of brain microcirculation resulting in cognitive dysfunction. Interestingly, memory cognitive dysfunction leads to a reduced adherence to drug treatment. Compliance with antihypertensive treatment improves BP control and arterial stiffness indices. Early treatment of arterial stiffness is strongly recommended for enhanced cognitive function and increased adherence.

The Contribution of Living Arrangements, Social Support, and Self-efficacy to Self-management Behaviors Among Individuals With Heart Failure: A Path Analysis

BACKGROUND

Living arrangements, social support, and self-efficacy have significant implications for self-management science. Despite the theoretical linkages among the 3 concepts, there is limited empirical evidence about their interplay and the subsequent influence on heart failure (HF) self-management.

OBJECTIVE

The aim of this study was to validate components of the Individual and Family Self-management Theory among individuals with HF.

METHODS

This is a secondary analysis of cross-sectional data generated from a sample of 370 individuals with HF. A path analysis was conducted to examine the indirect and direct associations among social environment (living arrangements), social facilitation (social support) and belief (self-efficacy) processes, and self-management behaviors (HF self-care maintenance) while accounting for individual and condition-specific factors (age, sex, race, and HF disease severity).

RESULTS

Three contextual factors (living arrangements, age, and HF disease severity) had direct associations with perceived social support and self-efficacy, which in turn were positively associated with HF self-management behaviors. Living alone (β = -.164, P = .001) was associated with lower perceived social support, whereas being an older person (β = .145, P = .004) was associated with better support. Moderate to severe HF status (β = -.145, P = .004) or higher levels of perceived social support (β = .153, P = .003) were associated with self-efficacy.

CONCLUSIONS

Our results support the Individual and Family Self-management Theory, highlighting the importance of social support and self-efficacy to foster self-management behaviors for individuals with HF. Future research is needed to further explore relationships among living arrangements, perceived and received social support, self-efficacy, and HF self-management.

Covid-19 Pandemic: Maximizing Future Vaccination Treatments Considering Aging and Frailty

The COVID-19 pandemic is proving to be a multiplier of inequalities. Especially toward the elderly population. A voiceless scream that comes from geriatrics, nursing homes, hospices from all over Italy. They call it the silent massacre: from North to South, the bulletin of coronavirus positive—or already deceased—elderly people continues to grow exponentially without a chance to counter it. Population aging and chronicity are a question that needs to be addressed. Frailty is the most challenging expression of population aging, with major consequences for public health and clinical practice. It is a geriatric syndrome which consists in a state of higher vulnerability to stressors attributed to a lower homeostatic reserve due to an age-related multisystem physiological change. People over 60, and especially over 80, are particularly vulnerable to severe or fatal infection. Moreover, the age-related dysregulation of the immune system in the elderly (i.e., immunosenescence and inflammaging) results in poorer responses to vaccination. Physical frailty is an effective health indicator and it has previously shown to predict the response to the seasonal flu vaccine. These findings suggest that assessing frailty in the elderly may identify those who are less likely to respond to immunization and be at higher risk for COVID-19 and its complications. Moreover, cognitive frailty and neurocognitive disorders, mental health and reduced awareness of illness negatively impact on adherence to complex medication regimens among elderly patients. A worldwide research and development blueprint have been initiated to accelerate the development of vaccines and therapeutics for the COVID-19 outbreak. Considered the above, I suggest the importance to consider aging in thinking about future Civud-19 vaccination and treatment, focusing on the possible impact of physical and cognitive frailty.

Cognition, Physical Function, and Quality of Life in Older Patients With Acute Decompensated Heart Failure

BACKGROUND

Older adults with acute decompensated heart failure have persistently poor clinical outcomes. Cognitive impairment (CI) may be a contributing factor. However, the prevalence of CI and the relationship of cognition with other patient-centered factors such a physical function and quality of life (QOL) that also may contribute to poor outcomes are incompletely understood.

METHODS AND RESULTS

Older (≥60 years) hospitalized patients with acute decompensated heart failure were assessed for cognition (Montreal Cognitive Assessment [MoCA]), physical function (Short Physical Performance Battery [SPPB], 6-minute walk distance [6MWD]), and QOL (Kansas City Cardiomyopathy Questionnaire, Short Form-12). Among patients (N = 198, 72.1 ± 7.6 years), 78% screened positive for CI (MoCA of <26) despite rare medical record documentation (2%). Participants also had severely diminished physical function (SPPB 6.0 ± 2.5 units, 6MWD 186 ± 100 m) and QOL (scores of <50). MoCA positively related to SPPB (ß = 0.47, P < .001), 6MWD ß = 0.01, P = .006) and inversely related to Kansas City Cardiomyopathy Questionnaire Overall Score (ß = -0.05, P < .002) and Short Form-12 Physical Component Score (ß = -0.09, P = .006). MoCA was a small but significant predictor of the results on the SPPB, 6MWD, and Kansas City Cardiomyopathy Questionnaire.

CONCLUSIONS

Among older hospitalized patients with acute decompensated heart failure, CI is highly prevalent, is underrecognized clinically, and is associated with severe physical dysfunction and poor QOL. Formal screening may reduce adverse events by identifying patients who may require more tailored care.

The relationship between serum uric acid and cognitive function in patients with chronic heart failure

BACKGROUND

Evidence has shown that serum uric acid (UA) is associated with cognitive function, but this finding remains debatable. Serum UA is commonly elevated in patients with chronic heart failure (CHF), especially in men. However, the relationship between serum UA and cognitive function in CHF populations and stratified by sex are unclear. We aimed to examine whether serum UA was independently associated with cognitive function in CHF populations after controlling for demographic, medical and psychological variables and whether there was a sex difference in the association between serum UA and cognitive function among male and female CHF patients.

METHODS

One hundred ninety-two hospitalized patients with CHF underwent an assessment of cognitive function using the Montreal Cognitive Assessment (MoCA) and the determination of serum UA. Hyperuricemia was defined as serum UA ≥7 mg/dl in men and ≥ 6 mg/dl in women. Multiple linear hierarchical regression analyses were conducted to examine the independent association between serum UA and cognitive function in CHF populations and stratified by sex.

RESULTS

The mean serum UA concentration of participants was 7.3 ± 2.6 mg/dL. The prevalence of hyperuricemia was 54.7% (105 of 192) in CHF patients, 52.9% (64 of 121) in men, and 57.7% (41 of 71) in women. In the total sample, higher serum UA was associated with poorer cognitive function independent of demographic, medical and psychological variables (β = - 0.130, ΔR² = 0.014, p = 0.015). In sex-stratified groups, elevated serum UA was independently associated with worse cognitive function in men (β = - 0.247, ΔR² = 0.049, p = 0.001) but not in women (β = - 0.005, ΔR² = 0.000, p = 0.955).

CONCLUSIONS

Higher serum UA is independently associated with poorer cognitive function in CHF populations after adjusting for confounding variables. Furthermore, elevated serum UA is independently related to worse performance on cognitive function in men but not in women. More longitudinal studies are needed to examine the association between serum UA and cognitive function in CHF populations and stratified by sex.

Cognitive performance in older adults across Europe based on the SHARE database

With ageing mental health issues, as age-related cognitive decline, increase. This study aims to evaluate the prevalence of cognitive impairment among older European adults and to evaluate its association with clinical and sociodemographic variables, using SHARE. Numeracy, temporal orientation, verbal fluency, and memory were the measures used to evaluate cognitive performance. From 44 963 individuals included, mean age was 70.0±9.0 years old and 56.3% were female. Overall prevalence of impairment was of 13.0% (temporal orientation), 24.8% (numeracy), 27.6% (verbal fluency) and 50.5% (memory). Men showed higher impairment prevalence in temporal orientation and memory and lower in numeracy and verbal fluency. Age, fewer years of education, difficulties performing iADLs, physical inactivity, and poor self-perceived health were independently associated with impairment in all cognitive abilities. These results showed the burden of cognitive impairment across Europe. Factors identified as associated should be taken in consideration to develop effective interventions to prevent cognitive decline.

Cognitive Impairment, Chronic Kidney Disease, and 1-Year Mortality in Older Patients Discharged from Acute Care Hospital

The prognostic interaction between chronic kidney disease (CKD) and cognitive impairment is still to be elucidated. We investigated the potential interaction of overall cognitive impairment or defective constructional praxis and CKD in predicting 1-year mortality among 646 older patients discharged from hospital. The estimated glomerular filtration rate (eGFR) was calculated using the Berlin Initiative Study (BIS) equation. Cognitive impairment was assessed by the Mini Mental State Exam (MMSE) and defective constructional praxis was ascertained by the inherent MMSE item. The study outcome was 1-year mortality. Statistical analysis was carried out using Cox regression. After adjusting for potential confounders, the co-occurrence of eGFR <30 and overall cognitive impairment (Hazard Ratio (HR) = 3.12, 95% Confidence Interval (CI) = 1.26-7.77) and defective constructional praxis (HR = 2.50, 95% CI = 1.08-5.77) were associated with the outcome. No significant prognostic interaction of eGFR < 30 with either overall cognitive impairment (HR = 1.99, 95% CI = 0.38-10.3) or constructional apraxia (HR = 1.68, 95% CI = 0.33-8.50) was detectable, while only cognitive deficits were found significantly associated with the outcome in the interaction models (HR = 3.12, 95% CI = 1.45-6.71 for overall cognitive impairment and HR = 2.16, 95% CI = 1.05-4.45 for constructional apraxia). Overall cognitive impairment and defective constructional praxis may be associated with increased risk of 1-year mortality among older hospitalized patients with severe CKD. However, no significant prognostic interaction between CKD and cognitive impairment could be observed.

The relationships between cognitive function, literacy and HIV status knowledge among older adults in rural South Africa

INTRODUCTION

Although HIV prevalence is exceptionally high in South Africa, HIV testing rates remain below targeted guidelines. Older adults living with HIV are substantially more likely to remain undiagnosed than younger people. Cognitive function and literacy could play key roles in HIV status knowledge due to the decision-making processes required around weighing the costs and benefits of testing, navigating testing logistics and processing results. We aimed to assess the independent relationships among each of cognitive function, literacy and education with HIV status knowledge in a population-based sample of older adults living in a rural South African community with high HIV prevalence.

METHODS

We analyzed data from a population-based study of 5059 men and women aged 40 years and older in rural South Africa (Health and Aging in Africa: A Longitudinal Study of an INDEPTH community (HAALSI)). HAALSI surveys, conducted between 2014 and 2015, queried self-reported literacy, educational attainment and HIV status knowledge. Laboratory tests were conducted to assess true HIV sero-status. Cognitive function was assessed with a battery of cognitive tests measuring time orientation, immediate and delayed recall, and numeracy and coded using confirmatory factor analysis as a z-standardized latent variable. We estimated the relationship between the outcome of HIV status knowledge and each of three exposures: (1) latent cognitive z-score, (2) literacy and (3) education, using confounder-adjusted modified Poisson regression models in the study population overall and stratified by HIV sero-status.

RESULTS

We found that HIV status knowledge was higher among those with higher cognitive z-scores (adjusted Prevalence Ratio (aPR) (95% CI): 1.18 (1.14, 1.21) per standard deviation unit), and among literate participants (aPR (95% CI): 1.24 (1.16, 1.32) vs. non-literate participants). Taken together, the associations with literacy and cognitive function completely attenuated the otherwise positive association between educational attainment and HIV status knowledge. The magnitudes of effect were generally similar among laboratory-confirmed HIV-negative and HIV-positive participants.

CONCLUSIONS

Campaigns that target older adults in rural South Africa with HIV testing messages should carefully consider the cognitive and literacy levels of the intended audience. Innovations to ease the cognitive load associated with HIV testing could prove fruitful to increase HIV status knowledge.

Towards appropriate polypharmacy in older cardiovascular patients: How many medications do I have to take?

Background

Polypharmacy in older adults leads to increased risks of side effects and drug‐drug interactions, affecting their health outcomes and quality of life. Deprescribing, the act of simplifying medication regimens, is challenging due to the lack of consensus guidelines.

Hypothesis

To offer some guidance on managing medication regimens for older cardiovascular patients.

Methods

We reviewed the most recent pertinent guidelines and literature.

Results

This review provides practical considerations for appropriate prescribing in the older population with cardiovascular disease in order to strike a balance between unnecessary or harmful medications and therapies with proven long‐term benefits.

Conclusion

On‐going dialogue between healthcare providers and patients allows close monitoring of medication effectiveness and prevention of side effects. Medication regimens require individualization, as patients' goals of care change with advancing age.

Medication Adherence and Associated Factors among Chronic Heart Failure Clients on Follow Up Oromia Region, West Ethiopia

BACKGROUND

Chronic heart failure is a complex clinical syndrome with typical symptoms that can occur at rest or on effort. It requires patients to manage their lifestyle with their disease and when to notify their healthcare provider. The study was aimed to identify medication adherence and associated factors among chronic heart failure clients on follow up Oromia region, West Ethiopia, 2017.

METHODS

Institutional based cross-sectional study design was employed, after selecting three hospitals by lottery method and allocating respondents to the three hospitals proportionally. A total of 424 patients were admitted to the medical ward and/or chronic follow up of Nekemte referral, Gimbi, and Shambu hospitals. The data was collected using a structured questionnaire. The data was entered into Epi-data version 3.1, cleared, explored, and then exported to SPSS windows version 24.0 for further analysis. Variable having a p-value less than 0.05 in the bivariate analysis was a candidate for multivariable analysis and the effect of confounding variables was observed. Variables having a p-value less than 0.05 in the multivariable analysis were assumed significant.

RESULTS

A total of 424 respondents were included in the final analysis giving a 95.3% response rate. The result indicated that more than half of the study participants have adhered to prescribed medication. Respondents with good medication adherence were more likely to adhere to good self-care behavior [AOR (95% CI of OR) = 3.5(2.044, 5.96)]. Respondents whose limited fluid intake was one or half-liter per day were more likely to adhere to the medication [AOR (95% CI of OR) = 2.5(1.43, 4.49)]. It was also found that those patients who avoided spices, sauces and others in food are more likely to adhere to the medication [AOR (95% CI of OR) = 2.2 (1.152, 4.039)].

CONCLUSION AND RECOMMENDATION

Even if more than half of the study respondents have good medication and self-care adherence, still it needs great attention in health education over their visit. Health institutions are strongly recommended to give health education for clients and researchers to use advanced study design for measuring medication adherence and self-care behaviors.

Examination of attention, executive function, and memory as predictors of mortality risk in adults with systolic heart failure

BACKGROUND

The prevalence and impact of cognitive impairment in heart failure is increasingly recognized. Converging evidence points to global cognitive function as predictive of prognosis in adults with heart failure when assessed with screening tools. Additional work is needed to understand which domains of cognitive function are most relevant for prognosis.

AIMS

The present study sought to examine associations between domains of cognitive function and mortality risk in adults with heart failure.

METHODS

In the present prospective, observational cohort study, global cognitive function, attention, executive function, and memory were assessed by means of a comprehensive neuropsychogical battery in adults with systolic heart failure. Mortality data were obtained from the National Death Index (median follow-up 2.95 years). Relationships among each cognitive domain and mortality were assessed with Cox regression. Covariates included age, sex, heart failure severity, comorbidity and depressive symptoms.

RESULTS

Participants were 325 patients with systolic heart failure with a mean age of 68.6 years (59% men, 73% Caucasian). Following covariate adjustment, better global cognitive function, attention, and executive function were related to decreased mortality risk.

CONCLUSIONS

Future research is needed to clarify the underlying mechanisms of the association between cognitive impairment and mortality.

Association of Secondary Preventive Cardiovascular Treatment After Myocardial Infarction With Mortality Among Patients With Schizophrenia

IMPORTANCE

Cardioprotective medication use is an important secondary preventive treatment after cardiovascular events. Patients with schizophrenia have excess cardiovascular morbidity and mortality, but no studies have investigated whether taking recommended cardioprotective medication can reduce this excess mortality.

OBJECTIVE

To assess the association of exposure to secondary cardiovascular treatment with all-cause mortality after myocardial infarction among patients with schizophrenia compared with the general population.

DESIGN, SETTING, AND PARTICIPANTS

This nationwide cohort study included individuals admitted with first-time myocardial infarction in Denmark from January 1, 1995, to December 31, 2015. The cohort was dichotomously divided by a diagnosis of schizophrenia. Data on the prescription of guideline-recommended cardioprotective medication, including antithrombotics, β-blockers, vitamin K antagonist, angiotensin-converting enzyme inhibitors, and statins, were obtained from the nationwide registries.

EXPOSURES

Time exposed to cardioprotective medication.

MAIN OUTCOMES AND MEASURE

Cox proportional hazards regression was used to calculate hazard ratios (HRs) with 95% CIs for the association between treatment exposure and all-cause mortality after myocardial infarction between patients with and without schizophrenia.

RESULTS

The cohort included 105 018 patients with myocardial infarction, including 684 patients with schizophrenia (0.7%; 483 male [70.6%]; mean [SD] age at diagnosis, 57.3 [10.6] years) and 104 334 general population patients (99.3%; 73 454 male [70.4%]; mean [SD] age at diagnosis, 61.0 [10.6] years), with a total follow-up of 796 435 person-years and 28 059 deaths. Patients diagnosed with schizophrenia who did not receive cardioprotective treatment had the highest mortality rate (HR, 8.78; 95% CI, 4.37-17.64) compared with the general population treated, with treated patients diagnosed with schizophrenia having an increased HR of 1.97 (95% CI, 1.25-3.10). The analyses of the associations of different cardiac therapy strategies with mortality rates revealed that patients with schizophrenia who were treated with any combination of triple therapy had mortality rates similar to those observed in the general population (HR, 1.05; 95% CI, 0.43-2.52) in the multivariable analysis.

CONCLUSIONS AND RELEVANCE

Cardioprotective medication after myocardial infarction should be carefully managed to improve prognosis. The study results suggest that some of the increased cardiac mortality among patients with schizophrenia can be reduced if these patients are efficiently administered combinations of secondary preventive treatments after cardiac events.

Sleep quality and daytime sleepiness are not associated with cognition in heart failure

BACKGROUND

Individuals with heart failure (HF) exhibit comorbid impairments in both sleep and cognitive performance. Sleep quality has been associated with impaired cognitive performance in HF patients, but reports are inconsistent. In this study, we examined associations between sleep quality, daytime sleepiness, and cognitive function in HF.

METHODS AND RESULTS

Participants were 267 (age = 69.1 ± 9.3) mostly Caucasian (74.9%), male (59.6%) stable HF patients recruited from outpatient settings. This cross-sectional study was a secondary analysis of a prospective observational study. Cognitive function domains assessed included: global cognitive function, attention, memory, and executive function. Sleep quality and daytime sleepiness were assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS), respectively. Separate multiple hierarchical linear regressions were conducted to determine associations between cognitive function and sleep quality and daytime sleepiness, after controlling for sex, New York Heart Association (NYHA) class, education, depressive symptoms, and medical comorbidities. Cognitive function was not associated with sleep quality or daytime sleepiness after alpha inflation corrections were applied.

CONCLUSIONS

Cognitive function in HF is not associated with sleep quality or daytime sleepiness; other factors may exert greater influence on cognitive performance.

In-Hospital Initiation of Guideline-Directed Heart Failure Pharmacotherapy to Improve Long-Term Patient Adherence and Outcomes

Heart failure is a burdensome cardiovascular condition associated with high rates of morbidity and mortality. The 3-month period after hospitalization is a vulnerable phase in which patients are at high risk for mortality and rehospitalization. To reduce risk during this period, patients with heart failure and reduced ejection fraction should receive guideline-directed pharmacological therapies—the right drugs at the right doses—before hospital discharge. Optimal pharmacotherapies for these patients include agents that suppress the renin-angiotensin-aldosterone system, suppress the sympathetic nervous system, enhance vasodilation, slow heart rate when needed, and reduce excess volume. Because optimal prescription and adherence are both necessary to ensure the best clinical outcomes, nurses need to participate in interventions that optimize prescription and drug use over time. Collaboration with pharmacists and advanced practice acute care nurses may help ensure that medication selection and dosing are consistent with national guidelines. Use of a predischarge order set and electronic medical records checklist can enhance collaborative care.

Relation between cognitive impairment and treatment adherence in elderly hypertensive patients

Background

Nonadherence to medical treatment and lack of cooperation in hypertensive patients >65 years of age are believed to be caused by a number of age-related problems, such as cognitive impairment. Numerous epidemiological and prospective studies have demonstrated that hypertension that remains untreated for many years or is unsuccessfully treated for reasons such as poor compliance and adherence of the patient may lead to cognitive impairment.

Objective

The objective of this study was to investigate the occurrence of cognitive impairment and its effect on treatment compliance and adherence in elderly hypertensive patients.

Design

This study was an analytical cross-sectional study.

Patients and methods

The study was conducted on 300 patients aged 65-91 years (mean age=71.8 years, SD=7.8 years) diagnosed with hypertension. The following research tools were used: 1) Hill-Bone High Blood Pressure Compliance Scale (HBCS) and 2) Mini-Mental State Examination (MMSE). We also analyzed medical documentation to obtain basic sociodemographic and clinical data. The study was approved by the Bioethics Committee of the Medical University of Wrocław (no KB-144/2016).

Results

Cognitive impairment occurred in 60% of the patients. A group of 63% patients complied with antihypertensive therapy, with the mean score of 20.8 points. Cognitive impairment was strongly correlated with the total score of the HBCS questionnaire (p<0.001) and two of its subscales: "appointment keeping" (p<0.001) and "medication taking" (p<0.001).

Conclusion

Compliance and adherence levels are higher in patients with a higher educational level, whereas male sex adversely affects treatment adherence in elderly hypertensive patients.

Factors associated with cognitive impairment in elderly versus nonelderly patients with metabolic syndrome: the different roles of FGF21

Increased fibroblast growth factor 21 (FGF21) levels have been found in patients with metabolic syndrome (MetS). MetS is also associated with cognitive decline. However, the correlation between FGF21 and cognitive decline in elderly and nonelderly MetS patients has not been investigated. 116 non-elderly patients (age <65 years old) and 96 elderly patients (≥65 years old) with MetS were enrolled. Blood samples for FGF21 were collected from all participants after 12-hour fasting. Cognitive function was assessed using the Montreal cognitive assessment (MoCA) test. The MoCA score was negatively associated with age and was different among different levels of education in these MetS patients. In the non-elderly group, body mass index (BMI) showed positively correlated with MoCA score while, FGF21 level and HbA1C were negatively associated with the MoCA score in non-elderly MetS patients. BMI was the only factor which showed a negative correlation with the MoCA score in elderly MetS patients. This study demonstrated that FGF21 level was independently associated with cognitive impairment in non-elderly patients but not in elderly patients. The possible role of FGF21 level in cognitive impairment in non-elderly should be confirmed in a prospective study.

Qualitative study of challenges of caring for a person with heart failure

Heart failure (HF) is a chronic health condition that causes significant morbidity among older adults, many of whom receive support and care from an informal caregiver. Caregiving is a difficult role with many responsibilities and challenges. An in-depth understanding of these challenges is necessary to develop services, resources, and interventions for HF caregivers. The goal of this study was to qualitatively ascertain the most significant challenges facing HF caregivers. We conducted semi-structured interviews with 16 caregivers of a person with HF (PHF). Content analysis revealed challenges rooted within the PHF (negative affect, resistant behavior, independence, and illness) Caregiver (balancing employment, lack of support, time, and caregiver health) and Relational level (PHF/caregiver dyadic relationship and other relationships). These findings can be used to inform interventions and support services for HF caregivers.

Factors Related to Self-Care in Heart Failure Patients According to the Middle-Range Theory of Self-Care of Chronic Illness: a Literature Update

Purpose of the Review

As described in the theory of self-care in chronic illness, there is a wide range of factors that can influence self-care behavior. The purpose of this paper is to summarize the recent heart failure literature on these related factors in order to provide an overview on which factors might be suitable to be considered to make self-care interventions more successful.

Recent Findings

Recent studies in heart failure patients confirm that factors described in the theory of self-care of chronic illness are relevant for heart failure patients.

Summary

Experiences and skills, motivation, habits, cultural beliefs and values, functional and cognitive abilities, confidence, and support and access to care are all important to consider when developing or improving interventions for patients with heart failure and their families. Additional personal and contextual factors that might influence self-care need to be explored and included in future studies and theory development efforts.
