The role of inflammation in predicting early cardiac complications among stroke patients is unclear. Electronic medical records from TriNetX, a global federated health research network, were used for this retrospective analysis. Patients with ischemic stroke and C-Reactive Protein (CRP) levels measured within 24 h post-stroke were categorized into three groups: (i) 3 mg/L. The primary outcome was a composite outcome of cardiac complications (heart failure (HF), ischemic heart disease, atrial fibrillation (AF), ventricular arrhythmias and Takotsubo cardiomyopathy) or death at 30 days from the index event. Cox-regression analyses were used to produce hazard ratios (HRs) and 95% confidence intervals (CI) following 1:1 propensity score matching (PSM). Of the 104,741 patients enrolled, 51% were female and the mean age was 66 ± 16 years. After PSM, a new cardiac complication or death within 30 days occurred in 5624 (33.1%) patients with CRP > 3 mg/L, in 4243 (25.6%) patients with CRP 1–3 mg/L and in 3891 (23.5%) patients with CRP 3 mg/L had higher risk of the composite outcome (HR 1.10, 95%CI 1.05–1.52; HR 1.51, 95%CI 1.45–1.58), death (HR 1.43, 95%CI 1.24–1.64; HR 3.50, 95%CI 3.01–3.96), HF (HR 1.08, 95%CI 1.01–1.16; HR 1.51, 95%CI 1.41–1.61), AF (HR 1.10, 95% CI:1.02–1.18; HR 1.42, 95%CI 1.33–1.52) and ventricular arrhythmias (HR 1.25, 95%CI 1.02–1.52; HR 1.67, 95% CI 1.38–2.01) compared to those with CRP 3 mg/L compared to those with CRP The role of inflammation in predicting early cardiac complications among stroke patients is unclear. Electronic medical records from TriNetX, a global federated health research network, were used for this retrospective analysis.

Ischemic heart disease were more common among patients with CRP levels > 3 mg/L compared to those with CRP < 1 mg/L (HR:1.33, 95% CI:1.26–1.40), while no association with Takotsubo cardiomyopathy was found in all the analyses. CRP levels within the first 24 h of an ischemic stroke predict 30-day cardiac complications or death.

BACKGROUND: Atrial fibrillation (AF) often remains undetected following stroke. Documenting AF is critical to initiate oral anticoagulation, which has proven benefit in reducing recurrent stroke and mortality in patients with AF. The accuracy and acceptability of using smart wearables to detect AF in patients following stroke is unknown.METHODS: The aims of the Liverpool-Huawei Stroke Study are to determine the effectiveness, cost-effectiveness and patient and staff acceptability of using Huawei smart wearables to detect AF following ischemic stroke. The study plans to recruit 1,000 adults aged ≥18 years following ischemic stroke from participating hospitals over 12 months. All participants will be asked to wear a Huawei smart band for 4 weeks postdischarge. If participants do not have access to a compatible smartphone required for the study, they will be provided with a smartphone for the 4-week AF monitoring period.RESULTS: Participants with suspected AF detected by the smart wearables, without previous known AF, will be referred for further evaluation. To determine the effectiveness of the Huawei smart wearables to detect AF, the positive predictive value will be determined. Patient acceptability of using this technology will also be examined. Additional follow-up assessments will be conducted at 6 and 12 months, and clinical outcomes recorded in relation to prevalent and incident AF post-stroke. The study opened for recruitment on May 30, 2022, and is currently open at 4 participating hospitals; the first 106 participants have been recruited. One further hospital is preparing to open for recruitment.CONCLUSIONS: This prospective study will examine the effectiveness and acceptability of the use of smart wearables in patients following ischemic stroke. This could have important implications for detection of AF and therefore, earlier prophylaxis for recurrent stroke. The study is registered on https://www.isrctn.com/ (Identifier ISRCTN30693819).

Aims Accumulating evidence questions the clinical value of percutaneous coronary intervention (PCI) for patients with chronic coronary syndrome (CCS). We therefore compare the impact of exercise-based cardiac rehabilitation (CR) vs. PCI in patients with CCS on 18-month mortality and morbidity, and evaluate the effects of combining PCI with exercise-based CR. Methods and results A retrospective cohort study was conducted in March 2021. An online, real-world dataset of CCS patients was acquired, utilizing TriNetX, a global federated health research network. Patients with CCS who received PCI were first compared with patients who were prescribed exercise-based CR. Second, we compared patients who received both CR + PCI vs. CR alone. For both comparisons, patients were propensity-score matched by age, sex, race, comorbidities, medications, and procedures. We ascertained 18-month incidence of all-cause mortality, rehospitalization, and cardiovascular comorbidity [stroke, acute myocardial infarction (AMI), and new-onset heart failure]. The initial cohort consisted of 18 383 CCS patients. Following propensity score matching, exercise-based CR was associated with significantly lower odds of all-cause mortality [0.37 (95% confidence interval (CI): 0.29–0.47)], rehospitalization [0.29 (95% CI: 0.27–0.32)], and cardiovascular morbidities, compared to PCI. Subsequently, patients that received both CR + PCI did not have significantly different odds for all-cause mortality [1.00 (95% CI: 0.63–1.60)], rehospitalization [1.00 (95% CI: 0.82–1.23)], AMI [1.11 (95% CI: 0.68–1.81)], and stroke [0.71 (95% CI: 0.39–1.31)], compared to CR only. Conclusions Compared to PCI, exercise-based CR associated with significantly lower odds of 18-month all-cause mortality, rehospitalization, and cardiovascular morbidity in patients with CCS, whilst combining PCI and exercise-based CR associated with lower incident heart failure only.

Pregnancy-related complications are associated with a higher risk of various incident cardiovascular diseases, but their specific potential relationship with incident atrial fibrillation (AF) is less clear. This systematic review summarises the available evidence from observational studies which have examined associations between pregnancy-related complications and the risk of AF. MEDLINE and EMBASE (Ovid) were searched for studies between 1990 to 10 February 2022. Pregnancy-related complications examined included hypertensive disorders of pregnancy (HDP), gestational diabetes, placental abruption, preterm birth, small-for-gestational-age and stillbirth. Study selection, data extraction and quality assessment were completed independently by two reviewers. Narrative synthesis was used to evaluate the results of the included studies. Nine observational studies were included, with eight eligible for narrative synthesis. Sample sizes ranged from 1839 to 2,359,386. Median follow-up ranged from 2 to 36 years. Six studies reported that pregnancy-related complications were associated with a significantly increased risk of incident AF. Hazard ratios (HRs) (95% confidence intervals) for the four studies that evaluated HDP ranged from 1.1 (0.8-1.6) to 1.9 (1.4-2.7). For the four studies that evaluated pre-eclampsia, HRs ranged from 1.2 (0.9-1.6) to 1.9 (1.7-2.2). Current evidence from observational studies suggests pregnancy-related complications are associated with a significantly higher risk of incident AF. However, only a small number of studies examining each pregnancy-related complication were identified, and considerable statistical heterogeneity was observed. Further large-scale prospective studies are required to confirm the association between pregnancy-related complications and incident AF.

Introduction: Endovascular thrombectomy (EVT) is associated with good clinical outcomes in patients with ischemic stroke, but the impact of EVT on clinical outcomes in patients with ischemic stroke with and without atrial fibrillation (AF), and the effect of adjunctive pharmacological therapies with EVT, remains unclear. Areas covered: The goal of this narrative review is to provide an overview of studies which have examined: 1) associations between EVT and outcomes for patients following ischemic stroke, 2) associations between EVT and outcomes for patients following ischemic stroke with and without AF, including function, reperfusion, hemorrhage, and mortality, 3) the effect of adjunctive pharmacological therapies peri- and post-thrombectomy, and 4) integration of prehospital care on endovascular treatment outcomes. Expert opinion: There is little evidence from randomized controlled trials on the effect of AF on stroke outcomes following EVT and the safety and efficacy of AF treatment in the peri-EVT such as tirofiban or Intravenous thrombolysis with Non-vitamin K Antagonist Oral Anticoagulant. The available evidence from observational studies on AF and EVT outcomes is inconsistent, but factors such as procedural EVT devices, the center volume, clinician experience, stroke recognition, and inclusion criteria of studies have all been associated with poorer clinical outcomes. Enhancing the clinical network among prehospital and hospitals will facilitate direct transfer to EVT centers, reducing stroke onset to EVT time and optimizing stroke outcomes.

OBJECTIVES: Endovascular thrombectomy (EVT) is associated with good clinical outcomes in ischaemic stroke, but the risk of intracerebral haemorrhage (ICH) and mortality remains common following ischaemic stroke. The effect of concomitant atrial fibrillation (AF) on clinical outcomes following acute ischaemic stroke in patients receiving EVT remains unclear. The aim is to investigate associations between AF and intracerebral haemorrhage and all-cause mortality at 90 days in patients with ischaemic stroke undergoing EVT.MATERIALS AND METHODS: A retrospective cohort was conducted using TriNetX, a global health research network. The network was searched for people aged ≥18 years with ischaemic stroke, EVT and AF recorded in electronic medical records between 01/09/2018 and 01/09/2021. These patients were compared to controls with ischaemic stroke, EVT and no AF. Propensity score matching for age, sex, race, comorbidities, National Institutes of Health Stroke Scale (NIHSS) scores, and prior use of anticoagulation was used to balance the cohorts with and without AF.RESULTS: In total 3,106 patients were identified with history of ischaemic stroke treated by EVT. After propensity-score matching, 832 patients (mean age 68 ± 13; 47% female) with ischaemic stroke, EVT and AF, were compared to 832 patients (mean age 67 ± 12; 47% female) with ischaemic stroke, EVT and no history of AF. In the cohort with AF, 11.5% (n = 96) experienced ICH within 90 days following EVT, compared with 12.3% (n = 103) in patients without AF (Odds Ratio (OR) 0.92, 95% confidence interval (CI) 0.68-1.24; p = 0.59). In the patients with AF, mortality within 90 days following EVT was 18.7% (n = 156), compared with 22.5% in patients without AF (n = 187) (OR 0.79, 95% CI 0.63-1.01; p = 0.06).CONCLUSION: In patients with ischaemic stroke undergoing EVT, AF was not significantly associated with intracerebral haemorrhage or all-cause mortality at 90-day follow-up.

Introduction People with atrial fibrillation (AF) frequently have competing mechanisms for ischaemic stroke, including extracranial carotid atherosclerosis. The objective of this study was to determine associations between use of oral anticoagulants (OACs) plus antiplatelet agents (APA) after ischaemic stroke and outcomes for patients with AF and carotid artery disease. Patients and Methods A retrospective cohort study was conducted. Participants receiving OACs with or without APA were propensity score–matched for age, sex, ethnicity, co-morbidities and presence of cardiac and vascular implants and grafts. Outcomes were 1-year mortality, recurrent stroke and major bleeding. Results Of 5708 patients, 24.1% (n=1628) received non-vitamin K antagonist OACs (NOACs) with no APA, 26.0% (n=1401) received NOACs plus APA, 20.7% (n=1243) received warfarin without APA and 29.2% (n=1436) received warfarin plus APA. There was no significant difference in risk of recurrent stroke between the groups. Compared to receiving NOACs without APA, receiving warfarin plus APA was associated with a higher risk of mortality (hazard ratio (HR) 1.51 (95% confidence interval (CI) 1.20, 1.89)) and major bleeding (HR 1.66 (95% CI 1.40, 1.96)). Receiving NOACs plus APA was also associated with a higher risk of major bleeding compared to NOACs without APA (HR 1.27 (95% CI 1.07, 1.51), respectively). Conclusions The results suggest for patients with AF and carotid artery disease after ischaemic stroke, receiving NOACs without APA is associated with a lower risk of major bleeding with no negative impact on recurrent stroke or mortality. Evidence from randomised trials is needed to confirm this finding.

Background Adiposity increases risk for male lower urinary tract symptoms (LUTS), although longitudinal studies have produced conflicting results. No prior studies have evaluated longitudinal associations of changes in adiposity with concurrent LUTS severity among older men. Methods We used repeated adiposity measurements from dual-energy x-ray absorptiometry (DXA), body mass index (BMI), and American Urological Association Symptom Index (AUASI) measured at 4 study visits over a 9-year period among 5 949 men enrolled in the Osteoporotic Fractures in Men (MrOS) study. Linear mixed effect models adjusted for age, health-related behaviors, and comorbidities were created to evaluate the association between baseline and change in visceral adipose tissue (VAT) area, total fat mass, and BMI with change in LUTS severity measured by the AUASI. Results A nonlinear association was observed between baseline VAT area and change in AUASI: men in baseline VAT tertile (T) 2 had a lower annual increase in AUASI score compared to men in T1 and T3 (T2 vs T1: β = −0.07; 95% CI −0.12, −0.03; p = .008; T3 vs T1: NS) but differences were small. No significant associations were observed between change in VAT area and change in AUASI score. Neither baseline tertiles nor change in total fat mass or BMI were associated with change in AUASI score. Conclusions Changes in VAT area, total fat mass, and BMI were not associated with change in LUTS severity in this cohort. Thus, despite other health benefits, interventions targeting adiposity alone are unlikely to be effective for preventing or treating LUTS among older men.

The 2020 European Society of Cardiology guidelines endorse the Atrial Fibrillation Better Care (ABC) pathway as a structured approach for the management of atrial fibrillation (AF), addressing three principal elements: ‘A’ – avoid stroke (with oral anticoagulation), ‘B’ – patient-focused better symptom management, and ‘C’ – cardiovascular and comorbidity risk factor reduction and management. This review summarizes the definitions used for the ABC criteria in different studies and the impact of adherence/non-adherence on clinical outcomes, from 12 studies on seven different cohorts. All studies consistently showed statistically significant reductions in the risk of stroke, myocardial infarction, and mortality among those with ABC pathway adherent treatment. The ABC pathway provides a simple decision-making framework to enable consistent equitable care from clinicians in primary and secondary/tertiary care. Further research examining the impact of ABC pathway implementation in prospective cohorts utilizing consistent inclusion criteria and definitions of ‘A’, ‘B’, and ‘C’ adherent care is warranted.

Oral anticoagulants (OACs) reduce the risk of stroke for people with atrial fibrillation (AF), and OACs are recommended in evidence‐based guidelines for most people with AF. The net clinical benefit of OACs compared with no treatment or aspirin is clear for most people with AF, apart from those at lowest stroke risk. The common risk factors for incident AF are also risk factors for stroke and bleeding in AF.

Background: Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are effective anti-diabetic drugs improving cardiovascular outcomes in type 2 diabetes mellitus (T2DM) patients. This study investigated cardiovascular, cerebrovascular and cognitive outcomes of SGLT2i therapy in patients with atrial fibrillation (AF) and T2DM. Methods: Observational study using TriNetX, a global health research network of anonymised electronic medical records from real-world patients between January 2018 and December 2019. The network includes healthcare organisations globally but predominately in the United States. AF patients (ICD-10-CM code: I48) with T2DM were divided according to SGLT2i use or not, and balanced using propensity score matching (PSM). Patients were followed-up for 3-years. The primary endpoints were ischaemic stroke/transient ischemic attack (TIA), intracranial haemorrhage (ICH), and incident dementia. Secondary endpoints were incident heart failure and mortality. Results: We identified 89,356 AF patients with T2DM of which 5061 (5.7%) were taking a SGLT2i. After PSM, 5049 patients (mean age 66.7 ± 10.6 years; 28.9% female) were included in each group. At 3-years follow-up, the risk of ischaemic stroke/TIA was higher in patients not receiving SGLT2i (HR 1.12, 95% CI 1.01–1.24) and for ICH (HR 1.57, 95% CI 1.25–1.99) and incident dementia (HR 1.66, 95% CI 1.30–2.12). Incident heart failure (HR 1.50, 95% CI 1.34–1.68) and mortality (HR 1.77, 95% CI 1.58–1.99) risks were increased in AF patients not receiving SGLT2i. Conclusions: In our large ‘real world’ analysis of patients with concomitant AF and T2DM, SGLT2i reduced the risk of cerebrovascular events, incident dementia, heart failure and death.

Funding Acknowledgements Type of funding sources: None. Background Despite the benefits of exercise training in the secondary prevention of cardiovascular disease, there are conflicting findings for the impact of exercise-based cardiac rehabilitation (CR) on mortality for patients with heart failure (HF). Methods A retrospective cohort study was conducted which utilised a global federated health research network. Patients with a diagnosis of HF were compared between those with and without an electronic medical record of exercise-based CR within 6-months of a HF diagnosis. Patients with HF undergoing exercise-based CR were propensity score matched to HF patients without exercise-based CR by age, sex, race, co-morbidities, medications, and procedures. We ascertained 2-year incidence of all-cause mortality, hospitalisation, stroke, and atrial fibrillation. Results Following propensity score matching, a total of 40,364 patients with HF were identified. Exercise-based CR was associated with 42% lower odds of all-cause mortality (odds ratio 0.58, 95% confidence interval (CI): 0.54-0.62), 26% lower odds of hospitalisation (0.74, 95% CI 0.71-0.77), 37% lower odds of incident stroke (0.63, 95% CI 0.51-0.79), and 53% lower odds of incident atrial fibrillation (0.47, 95% CI 0.4-0.55) compared to matched controls. The beneficial association of exercise-based CR on all-cause mortality was consistent across stratification for sex, older age, included comorbidities, and HF subtype (all P Conclusions Exercise-based CR was associated with lower odds of all-cause mortality, hospitalisations, incident stroke and incident atrial fibrillation at 2-years follow-up for patients with HF. The beneficial association of CR and lower mortality was consistent for patients with HFrEF and HFpEF.

Background: The risk of major adverse cardiovascular events is substantially increased following a stroke. Although exercise-based cardiac rehabilitation has been shown to improve prognosis following cardiac events, it is not part of routine care for people following a stroke. We, therefore, investigated the association between cardiac rehabilitation and major adverse cardiovascular events for people following a stroke. Following a stroke, individuals have an increased risk of new-onset cardiovascular complications. However, the incidence and long-term clinical consequence of newly diagnosed cardiovascular complications following a stroke is unclear. The aim of the present study was to investigate the incidence and long-term clinical outcomes of newly diagnosed cardiovascular complications following incident ischemic stroke. Methods: A retrospective cohort study was conducted using anonymized electronic medical records from 53 participating health care organizations. Patients with incident ischemic stroke aged ≥18 years with 5 years of follow-up were included. Patients who were diagnosed with new-onset cardiovascular complications (heart failure, severe ventricular arrhythmia, atrial fibrillation, ischemic heart disease, Takotsubo syndrome) within 4-weeks (exposure) of incident ischemic stroke were 1:1 propensity score-matched (age, sex, ethnicity, comorbidities, cardiovascular care) with ischemic stroke patients who were not diagnosed with a new-onset cardiovascular complication (control). Logistic regression models produced odds ratios (OR) with 95% CIs for 5-year incidence of all-cause mortality, recurrent stroke, hospitalization, and acute myocardial infarction. Results: Of 365 383 patients with stroke with 5-year follow-up: 11.1% developed acute coronary syndrome; 8.8% atrial fibrillation/flutter; 6.4% heart failure; 1.2% severe ventricular arrythmias; and 0.1% Takotsubo syndrome within 4 weeks of incident ischemic stroke. Following propensity score matching, odds of 5-year all-cause mortality were significantly higher in stroke patients with acute coronary syndrome (odds ratio, 1.49 [95% CI, 1.44–1.54]), atrial fibrillation/flutter (1.45 [1.40–1.50]), heart failure (1.83 [1.76–1.91]), and severe ventricular arrhythmias (2.08 [1.90–2.29]), compared with matched controls. Odds of 5-year rehospitalization and acute myocardial infarction were also significantly higher for patients with stroke diagnosed with new-onset cardiovascular complications. Takotsubo syndrome was associated with significantly higher odds of 5-year composite major adverse cardiovascular events (1.89 [1.29–2.77]). Atrial fibrillation/flutter was the only new-onset cardiac complication associated with significantly higher odds of recurrent ischemic stroke at 5 years (1.10 [1.07–1.14]). Conclusions: New-onset cardiovascular complications diagnosed following an ischemic stroke are very common and associate with significantly worse 5-year prognosis in terms of major adverse cardiovascular events. People with stroke and newly diagnosed cardiovascular complications had >50% prevalence of recurrent stroke at 5 years.

The aims of this study are to prospectively investigate cardiovascular outcomes and risk factors for incident cardiovascular disease in a post-stroke cohort, and to externally validate, refine and expand current risk prediction models for cardiovascular and cardiovascular-related outcomes. The study sample size was based on the development of post-stroke risk prediction models for AF and was calculated as 1222 participants. The study design is a multicentre, prospective, observational cohort study. Participants will be adult patients admitted for ischaemic stroke confirmed by stroke physician or transient ischaemic attack (TIA) confirmed by MRI. Routinely collected data will be used in addition to the completion of simple validated questionnaires by the participants. Follow-up will be undertaken 12-months from the date of admission to hospital, in addition to linkage to routinely collected follow-up hospitalisation and mortality data. The primary outcomes are cardiovascular outcomes (including incident AF, stroke, TIA and myocardial infarction) at 12-month follow-up, all-cause mortality and mortality from cardiovascular causes, and incident cognitive impairment and dementia. Secondary outcomes include changes in function, depression, anxiety, fatigue and quality of life. The study has received approval from the Health Research Authority Research Ethics Committee (21/WA/0209), and is registered on https://www.clinicaltrials.gov/ (Identifier NCT05132465). Recruitment for the study began in October 2021 with completion of recruitment at all participating centres anticipated by October 2022.Keywords: stroke, risk prediction, epidemiology, cohort study

BACKGROUND: The objective of this study was to determine associations between use of oral anticoagulation (OAC) and stroke and bleeding-related outcomes for older people ≥80 years with atrial fibrillation (AF), and to determine trends over time in prescribing of OAC for this population.METHODS: A retrospective cohort study was conducted. People aged ≥80 years with AF receiving (1) no OAC; (2) warfarin; or (3) a non-vitamin-K antagonist oral anticoagulant (NOAC) between 2011 and 2019 were included. Propensity score matching was used to balance cohorts (no OAC, warfarin or a NOAC) on characteristics including age, sex, ethnicity, and co-morbidities. Cox proportional hazard models were used to derive hazard ratios (HRs) and 95% confidence intervals (CIs).RESULTS: The proportion of people aged ≥80 years receiving any OAC increased from 32.4% (n = 27,647) in 2011 to 43.6% (n = 110,412) in 2019. After propensity score matching, n = 169,067 individuals were included in the cohorts receiving no OAC or a NOAC. Compared to no OAC, participants receiving a NOAC had a lower risk of incident dementia (hazHR 0.68, 95% CI 0.65-0.71), all-cause mortality (HR 0.49, 95% CI 0.48-0.50), first-time ischaemic stroke (HR 0.87, 95% CI 0.83-0.91), and a higher risk of major bleeding (HR 1.08, 95% CI 1.05-1.11). Compared to participants receiving warfarin, participants receiving a NOAC had a lower risk of dementia (HR 0.90, 95% CI: 0.86-0.93), all-cause mortality (HR 0.74, 95% CI: 0.72-0.76), ischaemic stroke (HR 0.86, 95% CI: 0.82-0.90) and major bleeding (HR 0.88, 95% CI: 0.85-0.90). Similar results were observed when only including people with additional bleeding risk factors.CONCLUSIONS: The proportion of people aged ≥80 years receiving OAC has increased since the introduction of NOACs, but remains low. Use of a NOAC was associated with improved outcomes compared to warfarin, and compared to no OAC, except for a small but statistically significant higher risk of major bleeding.

Embolic stroke of undetermined source (ESUS) represents a heterogeneous subgroup of patients with cryptogenic stroke, in which despite an extensive diagnostic workup the cause of stroke remains uncertain. Identifying covert atrial fibrillation among patients with ESUS remains challenging. The increasing use of cardiac implanted electronic devices (CIED), such as pacemakers, implantable defibrillators, and implantable loop recorders (ILR), has provided important information on the burden of subclinical atrial fibrillation. Accumulating evidence indicate that long-term continuous monitoring, especially in selected patients with ESUS, significantly increases the possibility of atrial fibrillation detection, suggesting it may be a cost-effective tool in secondary stroke prevention. This review summarizes available evidence related to the use of long-term cardiac monitoring and the use of implantable cardiac monitoring devices in patients with ESUS.

BackgroundTreatment decisions about oral anticoagulants (OACs) for atrial fibrillation (AF) are complex in older care home residents.AimTo explore factors associated with OAC prescription.Design and settingRetrospective cohort study set in care homes in Wales, UK, listed in the Care Inspectorate Wales Registry 2017/18.MethodAnalysis of anonymised individual-level electronic health and administrative data was carried out on people aged ≥65 years entering a care home between 1 January 2003 and 31 December 2018, provisioned from the Secure Anonymised Information Linkage Databank.ResultsBetween 2003 and 2018, 14 493 people with AF aged ≥65 years became new residents in care homes in Wales and 7057 (48.7%) were prescribed OACs (32.7% in 2003 compared with 72.7% in 2018) within 6 months before care home entry. Increasing age and prescription of antiplatelet therapy were associated with lower odds of OAC prescription (adjusted odds ratio [aOR] 0.96 per 1-year age increase, 95% confidence interval [CI] = 0.95 to 0.96 and aOR 0.91, 95% CI = 0.84 to 0.98, respectively). Conversely, prior venous thromboembolism (aOR 4.06, 95% CI = 3.17 to 5.20), advancing frailty (mild: aOR 4.61, 95% CI = 3.95 to 5.38; moderate: aOR 6.69, 95% CI = 5.74 to 7.80; and severe: aOR 8.42, 95% CI = 7.16 to 9.90), and year of care home entry from 2011 onwards (aOR 1.91, 95% CI = 1.76 to 2.06) were associated with higher odds of an OAC prescription.ConclusionThere has been an increase in OAC prescribing in older people newly admitted to care homes with AF. This study provides an insight into the factors influencing OAC prescribing in this population.

BackgroundThe demand for residential aged care is increasing due to the ageing population. Optimising the design or adapting the physical environment of residential aged care facilities has the potential to influence quality of life, mood and function.ObjectivesTo assess the effects of changes to the physical environment, which include alternative models of residential aged care such as a 'home-like' model of care (where residents live in small living units) on quality of life, behaviour, mood and depression and function in older people living in residential aged care.Search methodsCENTRAL, MEDLINE, Embase, six other databases and two trial registries were searched on 11 February 2021. Reference lists and grey literature sources were also searched.Selection criteriaNon-randomised trials, repeated measures or interrupted time series studies and controlled before-after studies with a comparison group were included. Interventions which had modified the physical design of a care home or built a care home with an alternative model of residential aged care (including design alterations) in order to enhance the environment to promote independence and well-being were included. Studies which examined quality of life or outcomes related to quality of life were included. Two reviewers independently assessed the abstracts identified in the search and the full texts of all retrieved studies.Data collection and analysisTwo reviewers independently extracted data, assessed the risk of bias in each included study and evaluated the certainty of evidence according to GRADE criteria. Where possible, data were represented in forest plots and pooled.Main resultsTwenty studies were included with 77,265 participants, although one large study included the majority of participants (n = 74,449). The main comparison was home-like models of care incorporating changes to the scale of the building which limit the capacity of the living units to smaller numbers of residents and encourage the participation of residents with domestic activities and a person-centred care approach, compared to traditional designs which may include larger-scale buildings with a larger number of residents, hospital-like features such as nurses' stations, traditional hierarchical organisational structures and design which prioritises safety. Six controlled before-after studies compared the home-like model and the traditional environment (75,074 participants), but one controlled before-after study included 74,449 of the participants (estimated on weighting). It is uncertain whether home-like models improve health-related quality of life, behaviour, mood and depression, function or serious adverse effects compared to traditional designs because the certainty of the evidence is very low. The certainty of the evidence was downgraded from low-certainty to very low-certainty for all outcomes due to very serious concerns due to risk of bias, and also serious concerns due to imprecision for outcomes with more than 400 participants. One controlled before-after study examined the effect of home-like models on quality of life. The author stated "No statistically significant differences were observed between the intervention and control groups." Three studies reported on global behaviour (N = 257). One study found little or no difference in global behaviour change at six months using the Neuropsychiatric Inventory where lower scores indicate fewer behavioural symptoms (mean difference (MD) -0.04 (95% confidence interval (CI) -0.13 to 0.04, n = 164)), and two additional studies (N = 93) examined global behaviour, but these were unsuitable for determining a summary effect estimate. Two controlled before-after studies examined the effect of home-like models of care compared to traditional design on depression. After 18 months, one study (n = 242) reported an increase in the rate of depressive symptoms (rate ratio 1.15 (95% CI 1.02 to 1.29)), but the effect of home-like models of care on the probability of no depressive symptoms was uncertain (odds ratio 0.36 (95% CI 0.12 to 1.07)). One study (n = 164) reported little or no difference in depressive symptoms at six months using the Revised Memory and Behaviour Problems Checklist where lower scores indicate fewer depressive symptoms (MD 0.01 (95% CI -0.12 to 0.14)). Four controlled before-after studies examined function. One study (n = 242) reported little or no difference in function over 18 months using the Activities of Daily Living long-form scale where lower scores indicate better function (MD -0.09 (95% CI -0.46 to 0.28)), and one study (n = 164) reported better function scores at six months using the Interview for the Deterioration of Daily Living activities in Dementia where lower scores indicate better function (MD -4.37 (95% CI -7.06 to -1.69)). Two additional studies measured function but could not be included in the quantitative analysis. One study examined serious adverse effects (physical restraints), and reported a slight reduction in the important outcome of physical restraint use in a home-like model of care compared to a traditional design (MD between the home-like model of care and traditional design -0.3% (95% CI -0.5% to -0.1%), estimate weighted n = 74,449 participants at enrolment). The remaining studies examined smaller design interventions including refurbishment without changes to the scale of the building, special care units for people with dementia, group living corridors compared to a non-corridor design, lighting interventions, dining area redesign and a garden vignette.Authors' conclusionsThere is currently insufficient evidence on which to draw conclusions about the impact of physical environment design changes for older people living in residential aged care. Outcomes directly associated with the design of the built environment in a supported setting are difficult to isolate from other influences such as health changes of the residents, changes to care practices over time or different staff providing care across shifts. Cluster-randomised trials may be feasible for studies of refurbishment or specific design components within residential aged care. Studies which use a non-randomised design or cluster-randomised trials should consider approaches to reduce risk of bias to improve the certainty of evidence.

Older residents of long-term care facilities (LTCFs), also known as nursing homes, care homes, or residential aged care facilities, often have multiple health conditions and are exposed to polypharmacy. Use of high-risk medications such as opioids, glucose-lowering medications, antithrombotics, and antipsychotics is prevalent among residents of LTCFs. Ensuring appropriate use of high-risk medications is important to minimize the risk of medication-related harm in this vulnerable population. This paper provides an overview of the prevalence and factors associated with high-risk medication use among residents of LTCFs. Evidencebased strategies to optimize the use of high-risk medications and enhance resident outcomes are also discussed. Refereed/Peer-reviewed

In an Australian nursing home population, associations between cognitive function and 12-month hospitalizations and costs were examined. Participants with dementia had 57% fewer hospitalizations compared to those without dementia, with 41% lower mean hospitalization costs; poorer cognition scores were also associated with fewer hospitalizations. The cost per admission for those with dementia was 33% greater due to longer hospital stays (5.5 days versus 3.1 days for no dementia, p = .05). People with dementia were most frequently hospitalized for fractures. These findings have policy implications for increasing investment in accurate and timely diagnosis of dementia and fall and fracture prevention strategies to further reduce associated hospitalization costs Refereed/Peer-reviewed

OBJECTIVES: Our aim was to determine the association between protein intake (overall and by source) and all-cause and cause-specific mortality among older men. DESIGN: Prospective cohort study. SETTING: 5790 ambulatory community-dwelling older men from multicenter Osteoporotic Fractures in Men (MrOS) study. MEASUREMENTS: Total energy and protein intake, and protein intake by source (dairy, non-dairy animal, plant) were assessed using a 69-item food frequency questionnaire. We included up to 10-year follow-up with adjudicated cardiovascular, cancer and other mortality outcomes. We used time-to-event analysis with protein exposures, mortality outcome, and adjusted for possible confounders including age, center, education, race, smoking, alcohol use, physical activity, weight, total energy intake (TEI), and comorbidities. Hazard ratios were expressed per each unit=2.9% TEI decrement for all protein intake variables. RESULTS: The mean (SD) baseline age of 5790 men was 73.6 (5.8) y. There were 1611 deaths and 211 drop-outs prior to 10 years, and 3868 men who were alive at the 10-year follow-up. The mean (SD) total protein intake was 64.7 (25.8) g/d, while the mean (SD) intake expressed as percent of total energy intake (%TEI) was 16.1 (2.9) %TEI. Lower protein intake was associated with an increased risk of death, with unadjusted HR=1.11 (95% CI: 1.06, 1.17) and adjusted HR=1.09 (95% CI: 1.04, 1.14) and the associations for protein intake by source were similar. The adjusted HR for cancer mortality was HR=1.13 (95% CI: 1.03, 1.25) while the association for CVD mortality was HR=1.08 (95% CI: 0.99, 1.18). CONCLUSIONS: Low protein intake, irrespective of source, was associated with a modest increase in risk of all-cause and cause-specific mortality among older men. Special consideration should be given to level of protein intake among older adults.

Background There is a high burden of antipsychotic use in residential aged care facilities (RACFs) and there is concern regarding potential inappropriate prescribing of antipsychotics in response to mild behavioural symptoms. Antipsychotic use has been associated with a higher risk of mortality in community-dwelling older adults with dementia, but few studies have examined associations upon RACF entry. Aims To examine associations between incident antipsychotic use and risk of mortality for people with and without diagnosed dementia in RACFs. Methods A retrospective cohort study, employing a new-user design (individuals did not receive an antipsychotic 6 months before enrolment) of 265,820 people who accessed RACFs in Australia between 1/4/2008 and 30/6/2015 was conducted. Cox regression models were used to examine adjusted associations between antipsychotic use in the first 100 days of RACF entry and mortality. Results In the 100 days after entering care, 29,455 residents (11.1%) were dispensed an antipsychotic. 180,956 (68.1%) residents died [38,249 (14.4%) were related to cerebrovascular causes] over a median 2.1 years (interquartile range 1.0–3.6) follow-up. Of the residents included, 119,665 (45.0%) had a diagnosis of dementia. Incident antipsychotic use was associated with higher risk of mortality in residents with dementia (adjusted hazard ratio 1.20, 95% confidence interval 1.18–1.22) and without dementia (1.28, 1.24–1.31). Conclusion Initiation of antipsychotics after moving to RACFs is associated with a higher risk of mortality. Careful consideration of the potential benefits and harms should be given when starting a new prescription for antipsychotics for people moving to RACFs.

Objective: To examine the prevalence of psychotropic medicine dispensing before and after older people enter residential care. Design: Retrospective national cohort study; analysis of Registry of Senior Australians (ROSA) data. Setting, participants: All concession card-holding residents of government-subsidised residential aged care facilities in Australia who entered residential care for at least three months between 1 April 2008 and 30 June 2015. Main outcome measures: Proportions of residents dispensed antipsychotic, benzodiazepine, or antidepressant medicines during the year preceding and the year after commencing residential care,by quarter. Results: Of 322 120 included aged care residents, 68 483 received at least one antipsychotic (21.3%; 95% CI, 21.1–21.4%), 98 315at least one benzodiazepine (30.5%; 95% CI, 30.4–30.7%), and 122 224 residents at least one antidepressant (37.9%; 95% CI,37.8–38.1%) during their first three months of residential care;31 326 of those dispensed antipsychotics (45.7%), 38 529 of those dispensed benzodiazepines (39.2%), and 25 259 residents dispensed antidepressants (19.8%) had not received them in the year preceding their entry into care. During the first three months of residential care, the prevalence of antipsychotic (prevalence ratio[PR], 3.37; 95% CI, 3.31–3.43) and antidepressant dispensing (PR,1.05; 95% CI, 1.04–1.07) were each higher for residents with than for those without dementia; benzodiazepine dispensing was similar for both groups (PR, 1.01; 95% CI, 0.99–1.02). Conclusions: Dispensing of psychotropic medicines to older Australians is high before they enter residential care but increases markedly soon after entry into care. Non-pharmacological behavioural management strategies are important for limiting the prescribing of psychotropic medicines for older people in the community or in residential care.

OBJECTIVES: To determine the proportion of older people moving to care homes with a recent stroke, incidence of stroke after moving to a care home, mortality following stroke, and secondary stroke prevention management in older care home residents.DESIGN: Retrospective cohort study using population-scale individual-level linked data sources between 2003 and 2018 in the Secure Anonymized Information Linkage (SAIL) Databank.SETTING AND PARTICIPANTS: People aged ≥65 years residing in long-term care homes in Wales.METHODS: Competing risk models and logistic regression models were used to examine the association between prior stroke, incident stroke, and mortality following stroke.RESULTS: Of 86,602 individuals, 7.0% (n = 6055) experienced a stroke in the 12 months prior to care home entry. The incidence of stroke within 12 months after entry to a care home was 26.2 per 1000 person-years [95% confidence interval (CI) 25.0, 27.5]. Previous stroke was associated with higher risk of incident stroke after moving to a care home (subdistribution hazard ratio 1.83, 95% CI 1.57, 2.13) and 30-day mortality following stroke (odds ratio 2.18, 95% CI 1.59, 2.98). Severe frailty was not significantly associated with risk of stroke or 30-day mortality following stroke. Secondary stroke prevention included statins (51.0%), antiplatelets (61.2%), anticoagulants (52.4% of those with atrial fibrillation), and antihypertensives (92.1% of those with hypertension).CONCLUSIONS AND IMPLICATIONS: At the time of care home entry, individuals with history of stroke in the previous 12 months are at a higher risk of incident stroke and mortality following an incident stroke. These individuals are frequently not prescribed medications for secondary stroke prevention. Further evidence is needed to determine the optimal care pathways for older people living in long-term care homes with history of stroke.

Background: The risk of major adverse cardiovascular events is substantially increased following a stroke. Although exercise-based cardiac rehabilitation has been shown to improve prognosis following cardiac events, it is not part of routine care for people following a stroke. We therefore investigated the association between cardiac rehabilitation and major adverse cardiovascular events for people with stroke. Methods: This retrospective analysis was conducted on June 20, 2021, using anonymized data within TriNetX, a global federated health research network with access to electronic medical records from participating healthcare organizations, predominantly in the USA. All participants were aged ≥18 years with cerebrovascular disease and at least 2 years of follow-up. People with stroke and an electronic medical record of exercise-based cardiac rehabilitation were 1:1 propensity score matched to people with stroke but without cardiac rehabilitation using participant characteristics, comorbidities, cardiovascular procedures, and cardiovascular medications. Results: Of 836,923 people with stroke and 2-year follow-up, 2,909 met the inclusion for the exercise-based cardiac rehabilitation cohort. Following propensity score matching (n = 5,818), exercise-based cardiac rehabilitation associated with 53% lower odds of all-cause mortality (odds ratio 0.47, 95% confidence interval: 0.40–0.56), 12% lower odds of recurrent stroke (0.88, 0.79–0.98), and 36% lower odds of rehospitalization (0.64, 0.58–0.71), compared to controls. No significant association between cardiac rehabilitation and incident atrial fibrillation was observed. Conclusion: Exercise-based cardiac rehabilitation prescribed for people following a stroke associated with significantly lower odds of major adverse cardiovascular events at 2 years, compared to usual care.

BACKGROUND Telemedicine is an expanding and feasible approach to improve medical care for patients with long-term conditions. However, there is a poor understanding of patients’ acceptability of this intervention and their rate of uptake. OBJECTIVE To systematically review the current evidence on telehealth in the management of patients with long-term conditions, and to evaluate the patients’ uptake and acceptability of this technology. METHODS MEDLINE, SCOPUS, and CENTRAL were searched from date of inception to 5 February 2021, with no language restrictions. Studies were eligible for inclusion if they reported any of the following outcomes: (i) intervention uptake and adherence; (ii) study retention; (iii) patient acceptability, satisfaction and experience using intervention: (iv) changes in physiological values; (v) all-cause and cardiovascular related hospitalization; (vi) all-cause and disease specific mortality; (vii) patient-reported outcome measures; (viii) quality of life. Two reviewers independently assessed articles for eligibility. This systematic review was registered on PROSPERO (CRD42021236291). RESULTS Ninety-six studies were included and fifty-eight were pooled for meta-analyses. Meta-analyses showed reduction in mortality (RR= 0.71, 95% CI 0.56 to 0.89, P=0.003, I2=0%); and improvements in BP (MD -3.85 mmHg, 95% CI -7.03 to -0.68, P CONCLUSIONS Telehealth is a valid alternative to usual care, reducing mortality and improving self-management of the disease, with patients reporting good satisfaction and adherence. Further studies are required to address some potential concerns regarding higher hospitalisation rates and a lack of a positive impact on patients’ quality of life.

Background Cardiomyopathy is a common cause of atrial fibrillation (AF) and may also present as a complication of AF. However, there is a scarcity of evidence of clinical outcomes for people with cardiomyopathy and concomittant AF. The aim of the present study was therefore to characterize the prevalence of AF in major subtypes of cardiomyopathy and investigate the impact on important clinical outcomes. Methods and Results A retrospective cohort study was conducted using electronic medical records from a global federated health research network, with data primarily from the United States. The TriNetX network was searched on January 17, 2021, including records from 2002 to 2020, which included at least 1 year of follow‐up data. Patients were included based on a diagnosis of hypertrophic, dilated, or restrictive cardiomyopathy and concomitant AF. Patients with cardiomyopathy and AF were propensity‐score matched for age, sex, race, and comorbidities with patients who had a cardiomyopathy only. The outcomes were 1‐year mortality, hospitalization, incident heart failure, and incident stroke. Of 634 885 patients with cardiomyopathy, there were 14 675 (2.3%) patients with hypertrophic, 90 117 (7.0%) with restrictive, and 37 685 (5.9%) with dilated cardiomyopathy with concomitant AF. AF was associated with significantly higher odds of all‐cause mortality (odds ratio [95% CI]) for patients with hypertrophic (1.26 [1.13–1.40]) and dilated (1.36 [1.27–1.46]), but not restrictive (0.98 [0.94–1.02]), cardiomyopathy. Odds of hospitalization, incident heart failure, and incident stroke were significantly higher in all cardiomyopathy subtypes with concomitant AF. Among patients with AF, catheter ablation was associated with significantly lower odds of all‐cause mortality at 12 months across all cardiomyopathy subtypes. Conclusions Findings of the present study suggest AF may be highly prevalent in patients with cardiomyopathy and associated with worsened prognosis. Subsequent research is needed to determine the usefulness of screening and multisdisciplinary treatment of AF in this population.

Background: Cerebral blood flow is known to decline with increasing age and is a potential biomarker to distinguish between healthy and unhealthy ageing, where healthy ageing is defined as an absence of comorbidities in senescence. This review aims to synthesize evidence of cerebral blood flow changes over multiple brain regions, for use as a clinical reference or for in silico modelling. Summary: The search identified 1,087 studies, of which 33 met the inclusion criteria to map the difference in cerebral blood flow reduction between healthy ageing and Alzheimer’s disease. Analysis was also performed on the effect of imaging modality and brain region functionality as potential confounding factors. Key Messages: No significant difference was found between the specific functionality of a brain region and cerebral blood flow in healthy ageing (p = 0.65) or Alzheimer’s disease (p = 0.42). Arterial spin labelling MRI imaging was shown to measure statistically larger decreases in flow in both healthy ageing (p = 0.0001) and Alzheimer’s disease (p = 0.0465). Cerebral blood flow was shown to decrease 0.3–0.5% per year in healthy ageing, which increased to a decline of 2–5% per year in Alzheimer’s disease. There was large variability both between and within individual brain regions, and this variability increased greatly in Alzheimer’s disease. Future studies would add value by taking more cerebral blood flow measurements during Alzheimer’s disease progression and by investigating ageing with comorbidities such as hypertension.

Background: COVID-19 has a wide spectrum of cardiovascular sequelae including myocarditis and pericarditis; however, the prevalence and clinical impact are unclear. We investigated the prevalence of new-onset myocarditis/pericarditis and associated adverse cardiovascular events in patients with COVID-19. Methods and results: A retrospective cohort study was conducted using electronic medical records from a global federated health research network. Patients were included based on a diagnosis of COVID-19 and new-onset myocarditis or pericarditis. Patients with COVID-19 and myocarditis/pericarditis were 1:1 propensity score matched for age, sex, race and comorbidities to patients with COVID-19 but without myocarditis/pericarditis. The outcomes of interest were 6-month all-cause mortality, hospitalisation, cardiac arrest, incident heart failure, incident atrial fibrillation and acute myocardial infarction, comparing patients with and without myocarditis/pericarditis. Of 718,365 patients with COVID-19, 35,820 (5.0%) developed new-onset myocarditis and 10,706 (1.5%) developed new-onset pericarditis. Six-month all-cause mortality was 3.9% (n = 702) in patients with myocarditis and 2.9% (n = 523) in matched controls (p

Background The National Health Service in England “Long Term Plan” aims to prevent 150,000 strokes and myocardial infarctions over the next 10 years. To achieve this, resources are being allocated to improve early detection of conditions strongly associated with cardiovascular disease. This includes working towards people routinely knowing their “ABC” risk factors (“A”: atrial fibrillation (AF), “B': hypertension and “C”: high cholesterol) (1). Purpose The aims of this study were to: 1) determine the proportion of participants with “A”, “B”, and “C” criteria; and 2) to identify risk factors for patients fulfilling any of these criteria. Methods LIPIDOGRAM2015 was a nationwide cross-sectional survey for adults in Poland. Adults were recruited in 2015 and 2016 by 438 family physicians. For the ABC criteria, “A” was defined as AF identified in the medical records of the participant, “B” was defined as either systolic blood pressure greater than 140mmHg or diastolic blood pressure greater than 90mmHg or both, and “C” was defined as total cholesterol greater than 200mg/dL (5.17mmol/L). The scaled and centred dataset underwent principal component analysis using singular value decomposition to achieve dimensionality reduction. K-means clustering was used to stratify patients with Hartigan's rule being used to identify optimal K number (2–4). The p-value for statistical significance used in this study was p Results 13,724 patients were included in the study. 71.0% (n=9,747) of participants fulfilled the criteria for one or more of the “A”, “B” or “C” components (Fig. 1). 26 variables were used in this analysis with Principal Component Analysis showing 7 principal components explaining over 50% of the variance with 20 components explaining over 90%. K-means clustering was also performed, finding 39 separate clusters. Correlations and statistical significance tests showed a high degree of variability between variables. Participants with AF were older (mean (SD) 67.7 (9.5) vs 55.7 (13.7), p Conclusion Simple demographic and clinical variables could be used to guide targeted screening to increase population awareness of “ABC” status, allowing for a greater proportion of the population to be appropriately managed with cardiovascular prevention strategies.

BACKGROUND: It is unclear if direct-acting oral anticoagulants (DOACs) use before hospitalization due to COVID-19 diagnosis would potentially impact the severity and clinical outcomes thereafter. We compared 30-day hospitalization/re-hospitalization and clinical outcomes between patients on chronic DOAC therapy and patients not on oral anticoagulation (OAC) therapy at time of COVID-19 diagnosis.METHODS: We used data from TriNetX, a global federated health research network. Patients aged ≥18 years who were treated with DOACs at time of COVID-19 diagnosis between 20 January 2020 and 28 February 2021 were included, and matched with patients not on OAC therapy from the same period. All patients were followed-up at 30-days after COVID-19 diagnosis. The primary outcomes were all-cause mortality, hospitalization/re-hospitalization, venous thromboembolism (VTE) and intracranial hemorrhage (ICH).RESULTS: 738,423 patients were included. After propensity score matching (PSM), 26,006 patients remained in the study (13,003 on DOACs; 13,003 not on OAC). DOAC-treated patients (mean age 67.1 ± 15.4 years, 52.2% male) had higher relative risks (RRs) and lower 30-days event-free survival as compared to patients not on OAC for all-cause mortality (RR 1.27, 95% CI 1.12-1.44; Log-Rank test p = 0.010), hospitalization/re-hospitalization (RR 1.72, 95% CI 1.64-1.82; Log-Rank test p < 0.001) and VTE (RR 4.51, 95% CI 3.91-5.82; Log-Rank test p < 0.001), but not for ICH (RR 0.90, 95% CI 0.54-1.51; Log-Rank test p = 0.513).CONCLUSION: In COVID-19 patients, previous DOAC therapy at time of diagnosis was not associated with improved clinical outcomes or lower hospitalization/re-hospitalization rate compared to patients not taking OAC therapy.

Background Telemedicine is an expanding and feasible approach to improve medical care for patients with long-term conditions. However, there is a poor understanding of patients’ acceptability of this technology and their rate of uptake. Objective The aim of this study was to systematically review the current evidence on telemonitoring in the management of patients with long-term conditions and evaluate the patients’ uptake and acceptability of this technology. Methods MEDLINE, Scopus, and CENTRAL (the Cochrane Central Register of Controlled Trials) were searched from the date of inception to February 5, 2021, with no language restrictions. Studies were eligible for inclusion if they reported any of the following outcomes: intervention uptake and adherence; study retention; patient acceptability, satisfaction, and experience using the intervention; changes in physiological values; all-cause and cardiovascular-related hospitalization; all-cause and disease-specific mortality; patient-reported outcome measures; and quality of life. In total, 2 reviewers independently assessed the articles for eligibility. Results A total of 96 studies were included, and 58 (60%) were pooled for the meta-analyses. Meta-analyses showed a reduction in mortality (risk ratio=0.71, 95% CI 0.56-0.89; P=.003; I2=0%) and improvements in blood pressure (mean difference [MD]=−3.85 mm Hg, 95% CI −7.03 to −0.68; P=.02; I2=100%) and glycated hemoglobin (MD=−0.33, 95% CI −0.57 to −0.09; P=.008; I2=99%) but no significant improvements in quality of life (MD=1.45, 95% CI −0.10 to 3; P=.07; I2=80%) and an increased risk of hospitalization (risk ratio=1.02, 95% CI 0.85-1.23; P=.81; I2=79%) with telemonitoring compared with usual care. A total of 12% (12/96) of the studies reported adherence outcomes, and 9% (9/96) reported on satisfaction and acceptance outcomes; however, heterogeneity in the assessment methods meant that a meta-analysis could not be performed. Conclusions Telemonitoring is a valid alternative to usual care, reducing mortality and improving self-management of the disease, with patients reporting good satisfaction and adherence. Further studies are required to address some potential concerns regarding higher hospitalization rates and a lack of positive impact on patients’ quality of life.

Background It remains uncertain if prior use of oral anticoagulants (OACs) in COVID-19 outpatients with multimorbidity impacts prognosis, especially if cardiometabolic diseases are present. Clinical outcomes 30-days after COVID-19 diagnosis were compared between outpatients with cardiometabolic disease receiving vitamin K antagonist (VKA) or direct-acting OAC (DOAC) therapy at time of COVID-19 diagnosis. Methods A study was conducted using TriNetX, a global federated health research network. Adult outpatients with cardiometabolic disease (i.e. diabetes mellitus and any disease of the circulatory system) treated with VKAs or DOACs at time of COVID-19 diagnosis between 20-Jan-2020 and 15-Feb-2021 were included. Propensity score matching (PSM) was used to balance cohorts receiving VKAs and DOACs. The primary outcomes were all-cause mortality, intensive care unit (ICU) admission/mechanical ventilation (MV) necessity, intracranial haemorrhage (ICH)/gastrointestinal bleeding, and the composite of any arterial or venous thrombotic event(s) at 30-days after COVID-19 diagnosis. Results 2275 patients were included. After PSM, 1270 patients remained in the study (635 on VKAs; 635 on DOACs). VKA-treated patients had similar risks and 30-day event-free survival than patients on DOACs regarding all-cause mortality, ICU admission/MV necessity, and ICH/gastrointestinal bleeding. The risk of any arterial or venous thrombotic event was 43% higher in the VKA cohort (hazard ratio 1.43, 95% confidence interval 1.03–1.98; Log-Rank test p = 0.029). Conclusion In COVID-19 outpatients with cardiometabolic diseases, prior use of DOAC therapy compared to VKA therapy at the time of COVID-19 diagnosis demonstrated lower risk of arterial or venous thrombotic outcomes, without increasing the risk of bleeding.
