Background: In the presence of elevated cardiac filling pressures, the decline of blood pressure (BP) during the straining phase of a Valsalva manoeuvre is blunted or absent. We compared the use of non-invasively measured BP response to a Valsalva manoeuvre with clinical assessment and bioimpedance measurements to identify haemodialysis patients at risk of acute congestive heart failure (CHF).

Introduction: Both the prevalence of atrial fibrillation (AF) and its subsequent use of direct oral anticoagulants (DOACs) are rapidly increasing in patients of older age. In the absence of contra-indications, guidelines advocate anticoagulation based on the CHA2DS2-VASc score for all AF patients aged 75 and above. However, some practitioners are hesitant to prescribe anticoagulants to older and frail patients due to perceived elevated bleeding risks. This review delves into the comparative treatment outcomes of DOACs versus vitamin K antagonists (VKAs) in older patients with AF, particularly focusing on those of advanced age, frailty, increased risk of falling, chronic kidney disease (CKD), or with a history of major bleeding. Additionally, considerations on the use of off-label DOAC doses, the role of left atrial appendage (LAA) closure and future developments in factor XIa-inhibitors will be discussed., Results: While strong evidence supports the use of DOACs in the vital older patients with nonvalvular AF, it remains scant in frail patient groups. There is some evidence from non-randomized studies suggesting that the effect of DOACs compared with VKAs is consistent between frail and nonfrail patients. However, recent findings from a single randomized trial showed increased bleeding risks but comparable thromboembolic outcomes in frail individuals switching from VKAs to DOACs. In patients with an increased risk of falling, data suggest no relevant interaction of increased risk of falling on the effectiveness and safety of DOACs compared with warfarin. Resuming oral anticoagulants in patients with Af after major bleeding seems to be beneficial. Off-label low-dose DOAC is often prescribed to patients who were underrepresented in larger randomized trails because of an elevated risk of bleeding or overexposure to DOACs, but its effect on clinical outcomes remains uncertain., Conclusions: DOACs are the recommended oral anticoagulant for vital older patients with AF. The scarcity of data backing DOAC use in frail individuals, those with renal impairments, or significant bleeding history underscores the necessity for further investigation. However, existing evidence suggests at least similar effectiveness and safety and potential benefits for DOACs in these patient subsets. Therefore, there is no reason to suggest these patients should be treated differently than the established guidelines regarding anticoagulation., (© 2024. The Author(s).)

Background: Screening of high-risk patients is advocated to achieve early detection and treatment of clinical atrial fibrillation (AF). The Dutch-GERAF study will address two major issues. Firstly, the effectiveness and feasibility of an opportunistic screening strategy for clinical AF will be assessed in frail older patients and, secondly, observational data will be gathered regarding the efficacy and safety of oral anticoagulation (OAC)., Methods: This is a multicentre study on opportunistic screening of geriatric patients for clinical AF using a smartphone photoplethysmography (PPG) application. Inclusion criteria are age ≥ 65 years and the ability to perform at least three PPG recordings within 6 months. Exclusion criteria are the presence of a cardiac implantable device, advanced dementia or a severe tremor. The PPG application records patients' pulse at their fingertip and determines the likelihood of clinical AF. If clinical AF is suspected after a positive PPG recording, a confirmatory electrocardiogram is performed. Patients undergo a comprehensive geriatric assessment and a frailty index is calculated. Risk scores for major bleeding (MB) are applied. Standard laboratory testing and additional laboratory analyses are performed to determine the ABC-bleeding risk score. Follow-up data will be collected at 6 months, 12 months and 3 years on the incidence of AF, MB, hospitalisation, stroke, progression of cognitive disorders and mortality., Discussion: The Dutch-GERAF study will focus on frail older patients, who are underrepresented in randomised clinical trials. It will provide insight into the effectiveness of screening for clinical AF and the efficacy and safety of OAC in this high-risk population., Trial Registration: NCT05337202., (© 2024.

Objectives: The aim of this multicentre COVID-PREDICT study (a nationwide observational cohort study that aims to better understand clinical course of COVID-19 and to predict which COVID-19 patients should receive which treatment and which type of care) was to determine the association between atrial fibrillation (AF) and mortality, intensive care unit (ICU) admission, complications and discharge destination in hospitalised COVID-19 patients., Setting: Data from a historical cohort study in eight hospitals (both academic and non-academic) in the Netherlands between January 2020 and July 2021 were used in this study., Participants: 3064 hospitalised COVID-19 patients >18 years old., Primary and Secondary Outcome Measures: The primary outcome was the incidence of new-onset AF during hospitalisation. Secondary outcomes were the association between new-onset AF (vs prevalent or non-AF) and mortality, ICU admissions, complications and discharge destination, performed by univariable and multivariable logistic regression analyses., Results: Of the 3064 included patients (60.6% men, median age: 65 years, IQR 55-75 years), 72 (2.3%) patients had prevalent AF and 164 (5.4%) patients developed new-onset AF during hospitalisation. Compared with patients without AF, patients with new-onset AF had a higher incidence of death (adjusted OR (aOR) 1.71, 95% CI 1.17 to 2.59) an ICU admission (aOR 5.45, 95% CI 3.90 to 7.61). Mortality was non-significantly different between patients with prevalent AF and those with new-onset AF (aOR 0.97, 95% CI 0.53 to 1.76). However, new-onset AF was associated with a higher incidence of ICU admission and complications compared with prevalent AF (OR 6.34, 95% CI 2.95 to 13.63, OR 3.04, 95% CI 1.67 to 5.55, respectively)., Conclusion: New-onset AF was associated with an increased incidence of death, ICU admission, complications and a lower chance to be discharged home. These effects were far less pronounced in patients with prevalent AF. Therefore, new-onset AF seems to represent a marker of disease severity, rather than a cause of adverse outcomes., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Particularly in frail patients, anticoagulation may be underused because of the fear of bleeding., Objective: To determine whether the use of antithrombotic medication is an independent risk factor for mortality in frail elderly with repeated falls., Methods: All patients aged 65 years or older at the Fall and Syncope Clinic were eligible. Frailty was calculated with a Frailty Index (FI) based on the accumulation of deficits model. Risks were calculated with a cox regression analysis, adjusted for age, sex, and Frailty Index., Results: 663 patients were included in this analysis. The median age was 80 years, 438 were women (66%), 73% had polypharmacy, and 380 patients (57%) had cognitive impairment. The mean FI was 0.23 (sd 0.09), 182 patients were moderately frail (27.5%), and 259 (39.1%) were severely frail. A total of 140 (21%) used oral anticoagulation and 223 (34%) used antiplatelet agents. A total of 196 patients (29.6%) died during follow-up. In the adjusted cox regression model, the use of neither antiplatelets nor anticoagulation was associated with mortality. A strong association was found with frailty (HR 74.0, 95% CI 13.1-417.3) and a weak association with age (HR 1.05, 95% CI 1.03-1.08). A lower risk of mortality was seen in women (HR 0.5, 95% CI 0.3-0.6)., Conclusions: In this cohort of frail older patients, there was no independent association between the use of antithrombotic medication and mortality. A strong association with mortality was found with frailty, a weak association was found with age, and a lower mortality risk was found in women. Our data indicate that the fear of bleeding or increased mortality in frail patients with an indication for oral anticoagulation may be unjustified.

Sometimes there is doubt as to whether or not anticoagulants should be initiated, and if so which ones, in patients with atrial fibrillation and advanced age, increased frailty, or fall risk, kidney, or liver impairment, alcohol abuse, uncontrolled hypertension, or a history of major bleeding. These subgroups have increased risk of haemorrhage as well as thromboembolism. Treatment with anticoagulants is indicated in the vital elderly, preferably with direct oral anticoagulants as demonstrated by robust data. The available study results for the other subgroups may not be (fully) generalisable to clinical practice. In such patients, a comprehensive risk assessment is therefore advised; as is discussing the pros and cons of (not) using anticoagulants and of both type of anticoagulants. Only in exceptional cases is it justified not to use anticoagulants.

Objectives: To investigate the prevalence of potentially inappropriate prescribing (PIP) according to the revised STOPP/START criteria in older patients with falls and syncope., Study Design: We included consecutive patients with falls and syncope aged ≥65 years at the day clinic of the Northwest Clinics, the Netherlands, from 2011 to 2016. All medication use before and after the visit was retrospectively investigated using the revised STOPP/START criteria., Main Outcome Measures: The prevalence/occurrence of PIP before the visit, persistent PIP after the visit, and unaddressed persistent PIP not explained in the patient's chart., Results: PIP was present in 98 % of 374 patients (mean age 80 (SD ± 7) years; 69 % females). 1564 PIP occurrences were identified. 1015 occurrences persisted (in 91 % of patients). 690 occurrences (in 80 % of patients) were not explained in the patient's chart. The most frequent unaddressed persistent forms of PIP were prescriptions of vasodilator drugs for patients with orthostatic hypotension (16 %), and benzodiazepines for >4 weeks (10 %) or in fall patients (8 %), and omission of vitamin D (28 %), antihypertensive drugs (24 %), and antidepressants (17 %). 54 % of all medication changes were initiated for reasons beyond the scope of the STOPP/START criteria., Conclusions: Almost every patient in our study population suffered from PIP. In 80 %, PIP continued after the clinical visit, without an explanation in the patient's chart. The most frequent PIP concerned medication that increased the risk of falls or syncope, specifically vasodilator drugs and benzodiazepines. Physicians should be aware of PIP in older patients with falls and syncope. Further studies should investigate whether a structured medication review may improve clinical outcomes., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Objectives: Important precipitating risk factors for delirium such as infections, vascular disorders, and surgery are accompanied by a systemic inflammatory response. Systemic inflammatory mediators can induce delirium in susceptible individuals. Little is known about the trajectory of systemic inflammatory markers and their role in the development and outcome of delirium., Methods: This is a prospective cohort study of older patients undergoing acute surgery for hip fracture. Baseline characteristics were assessed preoperatively. During hospital admission, presence of delirium was assessed daily according to the Confusion Assessment Method criteria. This study compared the trajectory of serum levels of the C-reactive protein (CRP) between people with and without postoperative delirium. Blood samples were taken at baseline and at postoperative day 1 through postoperative day 5., Results: Forty-one out of 121 patients developed postoperative delirium after hip fracture surgery. Longitudinal analysis of the trajectory of serum CRP levels using the Generalized Estimating Equations (GEE) method identified that higher CRP levels were associated with postoperative delirium. CRP levels were higher from postoperative day 2 through postoperative day 5. No significant differences in serum CRP levels were found when we compared patients with short (1-2 days) and more prolonged delirium (3 days or more)., Conclusions: Delirium is associated with an increased systemic inflammatory response, and our results suggest that CRP plays a role in the underlying (inflammatory-vascular) pathological pathway of postoperative delirium., (© 2019 John Wiley & Sons, Ltd.)

Purpose: To evaluate different patterns of orthostatic hypotension (OH) and its relation to mortality in older patients with unexplained falls or syncope., Methods: This is an observational cohort study in consecutive patients aged ≥ 65 years with unexplained falls or syncope at a Fall Syncope day clinic November 2011 until May 2016. OH is defined as a decrease in systolic blood pressure (BP) ≥ 20 mmHg and/or in diastolic BP ≥ 10 mmHg during standing test. Main outcomes are the baseline characteristics and prevalence of patients with classical OH (decrease BP until 3 min), delayed OH (decrease of BP from 5 to 10 min) and continuous OH (decrease of BP for 10 min). Secondary outcome is the relation between different OH patterns and mortality., Results: Of 374 patients with a mean age of 80 year (SD 6.6), 56% of the patients had OH: 16% had classical OH, 8% delayed OH, 32% had continuous OH and 44% had no OH. Patients with continuous OH and patients with delayed OH tended to have a higher mortality compared to patients with classical OH, 14 vs. 5% (P = 0.07) and 17 vs. 5% (P = 0.06). This possible relation between OH patterns and mortality could not be confirmed in multivariate analysis., Conclusions: In these very old patients, there are various patterns of decline in standing BP. Delayed and continuous OH will be missed if BP is measured only for 3 min during standing. This is important because patients with continuous OH and delayed OH might have a relation with mortality. Our results encourage additional studies investigating the relation between different OH patterns and mortality., (© 2018. European Geriatric Medicine Society.)

Aims: To assess the diagnostic outcomes of a multidisciplinary pathway for elderly syncope patients., Methods and Results: Observational cohort study at a Fall and Syncope Clinic, including consecutive syncope patients aged ≥65 years between 2011 and 2014. Measurements: The sort, number, and accuracy of diagnoses resulting in syncope. Secondary outcomes: reliability of the medical history and the number of electrocardiogram (ECG) abnormalities. The 117 included patients (72% females) had a mean age of 80 ± 6.5 years and a mean of 11 ± 5 (mainly cardiovascular) comorbidities. We found 212 contributing diagnoses. Symptomatic orthostatic/postprandial hypotension was present in 45%, cardiac causes in 44% (rhythm or conduction disorders 24%, aortic stenosis 4%, cardiomyopathies 2%, suspected cardiac causes 15%), and reflex syncope in 21%; 6% remained without any explanation. The diagnosis of the cause of syncope was uncertain in 34.2%, probable in 15.4%, and definite/most likely in 50.4%. Cognitive impaired patients were less likely to give a reliable medical history regarding their syncope (72% vs. 98% in cognitive intact patients, P = 0.001). In only 25% of patients a useful eyewitness account was available. 64% of ECGs showed relevant abnormalities; 26% was suggestive of cardiac syncope, of which 20% showed an indication for device implantation., Conclusion: The majority of our elderly syncope patients had multiple contributing factors, often in addition to their primary diagnosis. Orthostatic/postprandial hypotension and cardiac disorders were the most frequent. Using a multidisciplinary approach, one or more possible explanations for the syncope were found in 94% of patients, with a definite diagnosis in 50%.

Objectives: To evaluate the prevalence of cognitive impairment (CI), including mild CI and dementia, in elderly patients with syncope and unexplained falls. In this population, we compared the use of the Mini-Mental State Examination (MMSE) with a cognitive screening test that assesses executive dysfunction typical of subcortical (vascular) CI, that is, the Montreal Cognitive Assessment (MoCA)., Design: Observational cohort study., Setting: Outpatient fall and syncope clinic., Participants: Consecutive patients aged ≥65 years with syncope and unexplained falls without loss of consciousness., Measurements: Baseline characteristics, functional status, MMSE, MoCA, and magnetic resonance imaging scans of the brain., Main Outcome: prevalence of CI, comparing the MMSE with the MoCA. CI was defined as an MMSE/MoCA score <26., Secondary Outcomes: MMSE/MoCA overall and subdomain scores, Fazekas and medial temporal lobe atrophy scores., Results: We included 200 patients, mean age 79.5 (standard deviation 6.6) years (Syncope Group: n = 101; Fall Group: n = 99). Prevalence of CI was 16.8% (MMSE) versus 60.4% (MoCA) in the Syncope Group (P < .001) and 16.8% (MMSE) versus 56.6% (MoCA) in the Fall Group (P < .001). Prevalence of CI did not differ between the Syncope Group and Fall Group with either method. Executive dysfunction was present in both groups., Conclusion: CI is as common in elderly patients with syncope as it is in patients with unexplained falls, with an overall prevalence of 58%. The MMSE fails as a screening instrument for CI in these patients, because it does not assess executive function. Therefore, we recommend the MoCA for cognitive screening in older patients with syncope and unexplained falls., (Copyright © 2016 AMDA – The Society for Post-Acute and Long-Term Care Medicine.
