Discordance between subjective and objective evaluations of cognitive function in old Japanese patients with heart failure

Is it time for Heart-Brain clinics? A clinical survey and proposition to improve current care for cognitive problems in heart failure

BACKGROUND

Cognitive impairment is highly prevalent among patients with heart failure (HF). International guidelines on the management of HF recommend screening for cognitive impairment and tailored care for patients with cognitive impairment. However, practical guidance is lacking. In this study, we explore cardiologists' perspective on screening and care for cognitive impairment in patients with HF. We give an example of a multidisciplinary Heart-Brain care pathway that facilitates screening for cognitive impairment in patients with HF.

METHODS

We distributed an online survey to cardiologists from the Dutch working groups on Geriatric Cardiology and Heart Failure. It covered questions about current clinical practice, impact of cognitive impairment on clinical decision-making, and their knowledge and skills to recognize cognitive impairment.

RESULTS

Thirty-six out of 55 invited cardiologists responded. Only 3% performed structured cognitive screening, while 83% stated that not enough attention is paid to cognitive impairment. More than half of the cardiologists desired more training in recognizing cognitive impairment and three-quarters indicated that knowing about cognitive impairment would change their treatment plan. Eighty percent agreed that systematic cognitive screening would benefit their patients and 74% wished to implement a Heart-Brain clinic. Time and expertise were addressed as the major barriers to screening for cognitive impairment.

CONCLUSION

Although cardiologists are aware of the clinical relevance of screening for cognitive impairment in cardiology patients, such clinical conduct is not yet commonly practiced due to lack of time and expertise. The Heart-Brain care pathway could facilitate this screening, thus improving personalized care in cardiology.

Problems experienced when swallowing solid oral dosage forms in older Japanese patients with dysphagia: A cross-sectional study

AIMS

We aimed to assess the difficulty in taking solid oral dosage forms (SODFs) among older people with dysphagia and clarify the relationship between difficulty in swallowing SODFs and swallowing function.

METHODS AND RESULTS

Outpatients from a dysphagia clinic aged ≥65 years were asked yes-or-no questions about the applicability of eight items regarding difficulty in taking SODFs. Additionally, a videofluorographic swallowing study (VFSS) was performed to assess their swallowing function. The Kruskal-Wallis test and Spearman's rank correlation coefficient were used to analyze the relationship between difficulty in taking SODFs and swallowing function.

RESULTS

Among the 93 participants, the average number of SODFs consumed was 5.8 ± 3.1. In the questionnaire, the average number of "yes" answers was 2.2 ± 2.2, and 65 patients (71.0%) answered "yes" to at least one question. Additionally, no significant relationship was observed between the perceived difficulty in swallowing SODFs and VFSS findings.

CONCLUSION

Approximately 70% of participants reported subjective difficulty in taking SODFs, showing that patients uniformly reported perceived difficulty in taking SODFs regardless of actual swallowing function. The results of this study suggest that patients must be questioned thoroughly about their SODFs use, regardless of the objective severity of their dysphagia.

Association between objective neurocognitive functioning and neurocognitive complaints in recurrent high-grade glioma: longitudinal evidence of cognitive awareness from EORTC brain tumor trials

BACKGROUND

Patients' reduced awareness of neurocognitive functioning (NCF) may negatively affect the reliability of patient-reported outcomes (PROs) and clinical decision-making. This study evaluated cognitive awareness, defined as the association between NCF and neurocognitive complaints, over the disease course of patients with recurrent high-grade glioma (HGG).

METHODS

We assessed NCF using the EORTC core clinical trial battery and neurocognitive complaints using the Medical Outcome Study questionnaire. Patients were categorised as impaired or intact, based on their neurocognitive performance. Spearman's rank correlations were calculated between NCF and neurocognitive complaints at baseline and each 12 weeks, until 36. The association between changes in NCF and neurocognitive complaints scores between these follow-up assessments was determined using Pearson's correlation.

RESULTS

A total of 546 patients were included. Neurocognitively impaired patients (n = 437) had more neurocognitive complaints (range: 10.51 [p < 0.001] to 13.34 [p = 0.001]) than intact patients (n = 109) at baseline, at 12 and 24 weeks. In intact patients, NCF and neurocognitive complaints were correlated for only one domain at baseline (0.202, p = 0.036), while in impaired patients correlations were more frequently found in various domains and time points (range: 0.164 [p = 0.001] to 0.334 [p = 0.011]). Over the disease course, NCF and neurocognitive complaints were correlated for only one domain at baseline (0.357, p = 0.014) in intact patients while in impaired patients they were correlated for more domains and time points (range: 0.222 [p < 0.001] to 0.366 [p < 0.001]).

CONCLUSION

Neurocognitively impaired patients with recurrent HGG are aware of their neurocognitive limitations at study entry and during follow-up, which should be considered in clinical decision-making and when interpreting PRO results.

Association between Rapid Dementia Screening Test score and clinical events in elderly patients with cardiovascular disease: a retrospective cohort study

AIMS

Cognitive decline is prevalent among patients with cardiovascular disease (CVD). Cognitive measurement has been considered as a standard assessment for secondary prevention; however, standard cognitive tests are sometimes infeasible due to time constraints. This study aimed to examine the association between the Rapid Dementia Screening Test (RDST), a brief screening tool for cognitive function, and clinical events in elderly patients with CVD.

METHODS AND RESULTS

This retrospective cohort study included 140 hospitalized patients with CVD who participated in inpatient cardiac rehabilitation (median age, 75 years; male, 67%). Cognitive function for each patient was assessed using the RDST and Montreal Cognitive Assessment (MoCA), a standard test of mild cognitive impairment. The clinical events assessed as outcomes included all-cause mortality and unplanned rehospitalization. Receiver-operating characteristic (ROC) curve analysis showed similar predictive accuracy for the study outcome (P = 0.337) between the RDST [area under the curve, 0.651; 95% confidence interval (CI), 0.559-0.743] and MoCA (0.625; 0.530-0.720). The ROC analysis identified a cut-off value of 9 points for the RDST (sensitivity, 77.8%; specificity, 50.5%). Patients with RDST ≤9 showed a poor survival rate compared with those with ≥10 points (log-rank test, P = 0.002; hazard ratio, 2.94, 95% CI, 1.46-5.94). This result was consistent even after adjusting for potential confounders.

CONCLUSION

The RDST was associated with clinical events in elderly patients with CVD and its predictive capability was comparable with that of MoCA, a standard cognitive test. The RDST may be useful in CVD as an alternative screening tool for cognitive decline.

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.

The Utility of Cognitive Screening in Asian Patients With Heart Failure: A Systematic Review

Background

The prevalence of undiagnosed cognitive impairment in patients with heart failure is alarmingly high in Asia. There is still no consensus on cognitive screening tools to detect cognitive impairment in the Asian heart failure population. The clinical implications based on our systematic review may help to improve cognitive screening practice for patients with heart failure in Asia.

Methods

This review is registered in the PROSPERO (CRD42021264288). Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, we searched PubMed, Embase, the Cumulative Index to Nursing and Allied Health Literature, Scopus, the Web of Science, PsycINFO, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, and Wanfang Data in English and Chinese literatures concerning heart failure and cognitive impairment.

Results

The search yielded 21 eligible studies. Only in five studies, cognitive brief tests, including the Montreal Cognitive Assessment (MoCA), the Mini-Mental State Examination (MMSE), and the Mini-Cog, were used as cognitive screening tools for Asian patients with heart failure. In the rest 16 studies, brief cognitive tests were used as screening tools for global cognition. Only one study validated screening tests against a gold standard formal neuropsychological assessment test battery. Among these studies, patients with heart failure tended to perform worse than patients without heart failure. The presence of cognitive impairment in patients with heart failure is associated with poorer self-care, quality of life, and hospital readmission.

Conclusion

Brief cognitive tests have been used in Asian patients with heart failure and these tests are frequently used as a measure of global cognitive function for cognitive screening. However, validating brief cognitive tests against a gold standard formal neuropsychological assessment in Asian patients with heart failure is lacking. Future studies need to address methodological issues to validate cognitive screening measures in a larger population of Asian patients with heart failure.Systematic Review Registration: https://www.crd.york.ac.uk/prospero/.

Prevalence and Incidence of Cognitive Impairment and Dementia in Heart Failure - A Systematic Review, Meta-Analysis and Meta-Regression

INTRODUCTION

The burden of cognitive impairment in HF patients is significant and leads to longer hospital stay, higher readmission rates, and increased mortality. This review seeks to synthesize the available studies to determine the prevalence and incidence of cognitive impairment and dementia in HF patients.

METHODS

PubMed, Embase, PsychoINFO and Cochrane databases were systematically searched from their inception through to 3 May 2021. Study and population characteristics, total patients with HF, prevalence of cognitive impairment and dementia in HF patients and cognitive assessment tool were abstracted by two reviewers.

RESULTS

In heart failure patients, overall prevalence for cognitive impairment and dementia was 41.42% (CI) and 19.79% (dementia) respectively. We performed a meta-regression analysis which demonstrated that the risk of cognitive impairment and dementia increased with age.

DISCUSSION

Further research should investigate whether HF accelerates the rate of cognitive decline and the progression of dementia.

Prevalence and Determinants of Cognitive Impairment in Elderly Patients With Heart Failure - Pilot Study in a Geriatric Hospital

Background: Elderly patients admitted to hospital with heart failure (HF) often have cognitive impairment, but the association between these conditions is unclear.

Methods and Results: We enrolled 43 patients admitted to a geriatric hospital with HF. We evaluated echocardiography, Mini Mental State Examination (MMSE), and extracellular water/total body water (ECW/TBW) ratio (Inbody S10). Mean age was 85.1±8.0 years (range, 60–99 years) and 44.2% of the patients were men. Mean MMSE score was 20.5±5.4, with 66.7% of the patients showing cognitive impairment (MMSE ≤23). There was a significant negative correlation of MMSE score with age (r=−0.344, P=0.032), regular alcohol drinking (r=0.437, P=0.007), uric acid level (r=0.413, P=0.010), and ECW/TBW ratio (r=−0.437, P=0.007). On stepwise regression analysis including these covariates, MMSE score was significantly associated with the ECW/TBW ratio (β=0.443, P=0.009). When several echocardiography parameters (i.e., end-diastolic left ventricular volume, r=0.327, P=0.048; left atrial volume index, r=−0.411, P=0.012; and transmitral inflow A wave velocity, r=−0.625, P=0.001) were added to the model, MMSE score was found to be related to the A wave (P=0.001) and to atrial volume index (P=0.015), which are measures of diastolic function.

Conclusions: In elderly patients with HF, cognitive function might be influenced by body water distribution and diastolic heart function.
