Role of Geriatric Syndromes in the Management of Atrial Fibrillation in Older Adults: A Narrative Review

Profiles of Geriatric Syndromes and Resources in Older Patients with Atrial Fibrillation

Objective: Older patients with nonvalvular atrial fibrillation (AF) are at high risk for frailty and geriatric syndromes (GSs), which modulate their individual prognosis and are therefore relevant for further management. Because few studies have evaluated the geriatric profile of older AF patients, this secondary analysis aims to further characterize the patterns of GSs and geriatric resources (GRs) in AF patients and their association with anticoagulation use. Methods: Data from 362 hospitalized patients aged 65 years and older with AF (n = 181, 77.8 ± 5.8 years, 38% female) and without AF (non-AF [NAF]; n = 181, 77.5 ± 5.9 years, 40% female) admitted to an internal medicine and nephrology ward of a large university hospital in Germany were included. All patients underwent usual care plus a comprehensive geriatric assessment (CGA) including calculation of the Multidimensional Prognostic Index (MPI) and collection of 17 GSs and 10 GRs. Patients were followed up by telephone 6 and 12 months after discharge to collect data on their health status. Results: The mean MPI score of 0.47 indicated an average risk of poor outcome, and patients with AF had a significantly higher MPI than those without AF (p = 0.040). After adjustment for chronological age, biological sex, Cumulative Illness Rating Scale (CIRS) for relevant chronic diagnoses and MPI as a proxy for biological age, AF patients had significantly more mnestic resources (63.5% vs. 33.1%, p < 0.001), a tendency for less age-appropriate living conditions (56.4% vs. 72.9%, p = 0.051) and more sensory impairment (78.5% vs. 52.5%, p < 0.001) than NAF patients. They also had a higher number of GSs (p = 0.046). AF patients on oral anticoagulants (OACs, n = 91) had less age-appropriate living conditions (48.4% vs. 64.4%, p < 0.05) and mnestic resources (36.3% vs. 54.4%, p < 0.01), but more emotional resources (80.2% vs. 65.6%, p < 0.05) and chronic pain (56% vs. 40%, p < 0.05) than patients without OACs (n = 90). Overall, mortality at 1 year was increased in patients with a higher MPI (p < 0.009, adjusted for age, sex and CIRS), with a diagnosis of AF (p = 0.007, adjusted for age, sex, CIRS and MPI), with of male sex (p = 0.008, adjusted for age, CIRS and MPI) and those with AF and treated with hemodialysis (p = 0.022, compared to AF patients without dialysis treatment). Conclusions: Patients with AF and patients with AF and OACs show differences in their multidimensional frailty degree as well as GR and GS profiles compared to patients without AF or with AF not treated with OACs. Mortality after 1 year is increased in AF patients with a higher MPI and dialysis, independently from OAC use and overall burden of chronic disease as assessed per CIRS. GRs and GSs, especially age-appropriate living conditions, emotional resources, sensory impairment and chronic pain, can be considered as factors that may modify the individual impact of frailty, underscoring the relevance of these parameters in the management of older patients.

Considerations Regarding Management of Heart Failure in Older Adults

Understanding noncardiovascular comorbidities and geriatric syndromes in elderly patients with heart failure (HF) is important as the average age of the population increases. Healthcare professionals need to consider these complex dynamics when managing older adults with HF, especially those older than 80. A number of small studies have described associations between HF and major geriatric domains. With information on patients' cognitive, functional decline, and ability to adhere to therapy, physicians can plan for individualized treatment goals and recommendations for these patients.

Depression and quality of life in older adults with atrial fibrillation: A cross-sectional community-based study

AIM

In the older population, depression often occurs alongside physical illness. A cross-sectional community-based study examined the relationship between atrial fibrillation (AF), depression, and quality of life (QoL), and the impact of chest symptoms.

METHODS

A total of 1364 older adults (≥65 years) who attended AF awareness symposia from July 2019 to December 2020 provided consent to participate in the study and valid questionnaire responses. Depression was assessed with the Geriatric Depression Scale (GDS)-15, and QoL with the 12-item Short-Form Health Survey (SF-12).

RESULTS

AF patients (n = 130) were divided into symptomatic AF (n = 87) and asymptomatic AF (n = 43) groups. Depressive state and physical component summary (PCS) and mental component summary (MCS) in the SF-12 were compared with the control group (non-AF group without chest symptoms, n = 911), extracted from the same symposium participants. The depression rate (defined as GDS-15 ≥ 10) was 9.2% in symptomatic AF patients, 2.3% in asymptomatic AF patients, and 2.7% in controls. The mean PCS and MCS in each group were 43.4 ± 10.8 and 54.8 ± 8.6, 44.6 ± 10.7 and 57.3 ± 7.3, and 48.5 ± 7.9 and 56.7 ± 6.8, respectively. Multivariate regression analysis showed that symptomatic AF patients had a higher risk of depression (odds ratio: 3.46, 95% confidence interval (CI) 1.27-8.57, P = 0.01) and poor QoL (PCS: B -3.17, 95% CI -5.05 to -1.29, P = 0.001 and MCS: B -1.80, 95% CI -3.45 to -0.16, P = 0.03) compared with controls, but asymptomatic AF patients did not.

CONCLUSIONS

In a cross-sectional community-based study, symptomatic AF patients were vulnerable to depression and poor QoL, but asymptomatic AF patients were not. Geriatr Gerontol Int 2022; ••: ••-••.

A model for a geriatric teaching programme and its impact on self-rated and tested competencies of undergraduate dental students

INTRODUCTION

In the light of the growing ageing population, it is important that future dentists be taught geriatric competencies to assure good dental care and treatment addressing the special needs of older patients.

MATERIALS AND METHODS

We developed and evaluated a geriatric teaching programme amongst final year undergraduate dental students (n = 30) at the University of Bern, Switzerland. The geriatric teaching programme was based on the European undergraduate curriculum in geriatric medicine for medical students covering the following eight geriatric domains that were considered relevant to dental care: Analgesics, cognitive impairment, decision-making capacity, gait and balance disorder, hearing impairment, malnutrition, polypharmacy and vision impairment. Using a pre/post-design, we administered a structured questionnaire including standardised questions on self-rated and tested competencies. Both assessments scores were standardised to a maximum score of 100 points. Data were evaluated by comparison of pre-test and post-test mean scores.

RESULTS

The geriatric teaching programme proved to be feasible covering eight geriatric domains based on a case-based didactic approach in totally eight 45-minute lessons. Both self-rated and tested competencies of dental students increased in all eight domains in the course of the geriatric teaching programme. After the geriatric teaching programme, both mean self-rated competency scores (67.9 vs. 49.6, p < .001) and mean tested competency scores (78.7 vs. 56.7 points, p < .001) significantly improved compared to baseline.

CONCLUSIONS

Integrating a consolidated refined geriatric teaching programme is a potentially feasible and effective method for dental undergraduate students and is expected to have an impact on better dental care of older patients.

Relationship between number of medications and incidence of falls or bone fracture in elderly patients with non-valvular atrial fibrillation: Shinken database analysis

AIM

Polypharmacy is known to be a risk factor for falls or bone fracture (F/F) in elderly patients. However, this relationship is not fully described in patients with non-valvular atrial fibrillation (NVAF), for which F/F may lead to serious clinical outcomes, including major bleeding.

METHODS

We analyzed 509 elderly (aged ≥75 years) patients with NVAF who had recently visited a hospital specializing in cardiology, of which 272 patients had paroxysmal atrial fibrillation (PAF) and 237 had persistent/permanent atrial fibrillation (PeAF). Patients were divided into four groups according to the number of medications: ≤3, 4-6, 7-9, and ≥10. The relationship between the number of medications and incidence rate of F/F in AF patients was analyzed. In addition, this relationship was analyzed in patients with each AF type.

RESULTS

Cumulative incidence of F/F at 3 years in the respective categories was 3.7%, 5.4%, 4.3% and 5.7% for PAF, and 5.2%, 7.5%, 7.8% and 25.0% for PeAF (log-rank test, P = 0.930 and 0.003, respectively). In a multivariable model, patients with ≥10 medications showed a significantly higher risk for F/F compared with those with ≤3 medications as reference only in PeAF (adjusted hazard ratio 4.82, 95%CI 1.42-16.33), without significant interaction (P = 0.081).

CONCLUSIONS

Elderly NVAF patients using ≥10 medications showed a higher risk for F/F. In subgroup analysis, this association was observed only in patients with PeAF, although there was no significant interaction between number of medications and AF type. Geriatr Gerontol Int 2021; 21: 802-809.

Atrial fibrillation in the elderly: a risk factor beyond stroke

Atrial fibrillation (AF) represents the most common arrhythmia worldwide and its prevalence exponentially increases with age. It is related to increased risk of ischemic stroke or systemic embolism, which determines a significant burden of morbidity and mortality, as widely documented in the literature. AF also constitutes a risk factor for other less investigated conditions, such as heart failure, pulmonary embolism, impairment in physical performance, reduced quality of life, development of disability, mood disorders and cognitive impairment up to dementia. In the elderly population, the management of AF and its complications is particularly complex due to the heterogeneity of the ageing process, the lack of specific evidence-based recommendations, as well as the high grade of comorbidity and disability characterizing the over 65 years aged people. In the present review, we aim to summarize the pieces of the most updated evidence on AF complications beyond stoke, mainly focusing on the elderly population.
