Prevalence and Impact of Frailty in Patients ≥70 Years Old with Acute Coronary Syndrome Referred for Coronary Angiography.

INTRODUCTION: Elderly patients with acute coronary syndrome (ACS) have a higher risk of adverse cardiovascular events and may be frail but are underrepresented in clinical trials. Previous studies have proposed that frailty assessment is a better tool than chronological age, in assessing older patients' biological age, and may exceed conventional risk scores in predicting the prognosis. Therefore, we wanted to investigate the prevalence and impact on 12-month outcomes of frailty in patients ≥70 years with ACS referred for coronary angiography (CAG). METHODS: Patients ≥70 years with ACS referred for CAG underwent frailty scoring with the clinical frailty scale (CFS). Patients were divided into three groups depending on their CFS: robust (1-3), vulnerable (4), and frail (5-9) and followed for 12 months. RESULTS: Of 455 patients, 69 (15%) patients were frail, 79 (17%) were vulnerable, and 307 (68%) were robust. Frail patients were older (frail: 80.9 ± 5.7 years, vulnerable: 78.5 ± 5.5 years, and robust: 76.6 ± 4.9 years, p < 0.001) and less often treated with percutaneous coronary intervention (frail: 56.5%, vulnerable: 53.2%, and robust: 68.6%, p = 0.014). 12-month mortality was higher among frail patients (frail: 24.6%, vulnerable: 21.8%, and robust: 6.2%, p < 0.001). Frailty was associated with a higher mortality after adjustment for age, sex, comorbidities, the Global Registry of Acute Coronary Events (GRACE) score, and revascularisation (HR 2.67, 95% CI 1.30-5.50, p = 0.008). There was no difference between GRACE and CFS in predicting 12-month mortality (p = 0.893). CONCLUSIONS: Fifteen percent of patients ≥70 years old with ACS referred for CAG are frail. Frail patients have significantly higher 12-month mortality. GRACE and CFS are similar in predicting 12-month mortality.

Exercise-based cardiac rehabilitation for adults with atrial fibrillation.

BACKGROUND: Atrial fibrillation (AF), the most prevalent cardiac arrhythmia, disrupts the heart's rhythm through numerous small re-entry circuits in the atrial tissue, leading to irregular atrial contractions. The condition poses significant health risks, including increased stroke risk, heart failure, and reduced quality of life. Given the complexity of AF and its growing incidence globally, exercise-based cardiac rehabilitation (ExCR) may provide additional benefits for people with AF or those undergoing routine treatment for the condition. OBJECTIVES: To assess the benefits and harms of ExCR compared with non-exercise controls for people who currently have AF or who have been treated for AF. SEARCH METHODS: We searched the following electronic databases: CENTRAL in the Cochrane Library, MEDLINE Ovid, Embase Ovid, PsycINFO Ovid, Web of Science Core Collection Thomson Reuters, CINAHL EBSCO, LILACS BIREME, and two clinical trial registers on 24 March 2024. We imposed no language restrictions. SELECTION CRITERIA: We included randomised clinical trials (RCTs) that investigated ExCR interventions compared with any type of non-exercise control. We included adults 18 years of age or older with any subtype of AF or those who had received treatment for AF. DATA COLLECTION AND ANALYSIS: Five review authors independently screened and extracted data in duplicate. We assessed risk of bias using Cochrane's RoB 1 tool as outlined in the Cochrane Handbook for Systematic Reviews of Interventions. We assessed clinical and statistical heterogeneity by visual inspection of the forest plots and by using standard Chi² and I² statistics. We performed meta-analyses using random-effects models for continuous and dichotomised outcomes. We calculated standardised mean differences where different scales were used for the same outcome. We used the GRADE approach to assess the certainty of the evidence. MAIN RESULTS: We included 20 RCTs involving a total of 2039 participants with AF. All trials were conducted between 2006 and 2024, with a follow-up period ranging from eight weeks to five years. We assessed the certainty of evidence as moderate to very low. Five trials assessed comprehensive ExCR programmes, which included educational or psychological interventions, or both; the remaining 15 trials compared exercise-only cardiac rehabilitation with controls. The overall risk of bias in the included studies was mixed. Details on random sequence generation, allocation concealment, and use of intention-to-treat analysis were typically poorly reported. Evidence from nine trials (n = 1173) suggested little to no difference in mortality between ExCR and non-exercise controls (risk ratio (RR) 1.06, 95% confidence interval (CI) 0.76 to 1.49; I² = 0%; 101 deaths; low-certainty evidence). Based on evidence from 10 trials (n = 825), ExCR may have little to no effect on SAEs (RR 1.30, 95% CI 0.63 to 2.67; I² = 0%; 28 events; low-certainty evidence). Evidence from four trials (n = 378) showed that ExCR likely reduced AF recurrence (measured via Holter monitoring) compared to controls (RR 0.70, 95% CI 0.56 to 0.88; I² = 2%; moderate-certainty evidence). ExCR may reduce AF symptom severity (mean difference (MD) -1.59, 95% CI -2.98 to -0.20; I² = 61%; n = 600; low-certainty evidence); likely reduces AF symptom burden (MD -1.61, 95% CI -2.76 to -0.45; I² = 0%; n = 317; moderate-certainty evidence); may reduce AF episode frequency (MD -1.29, 95% CI -2.50 to -0.07; I² = 75%; n = 368; low-certainty evidence); and likely reduces AF episode duration (MD -0.58, 95% CI -1.14 to -0.03; I² = 0%; n = 317; moderate-certainty evidence), measured via the AF Severity Scale (AFSS) questionnaire. Moderate-certainty evidence from six trials (n = 504) showed that ExCR likely improved the mental component summary measure in health-related quality of life (HRQoL) of the 36-item Short Form Health Survey (SF-36) (MD 2.66, 95% CI 1.22 to 4.11; I² = 2%), but the effect of ExCR on the physical component summary measure was very uncertain (MD 1.75, 95% CI -0.31 to 3.81; I² = 52%; very low-certainty evidence). ExCR also may improve individual components of HRQoL (general health, vitality, emotional role functioning, and mental health) and exercise capacity (peak oxygen uptake (VO2peak) and 6-minute walk test) following ExCR. The effects of ExCR on serious adverse events and exercise capacity were consistent across different models of ExCR delivery: centre compared to home-based, exercise dose, exercise only compared to comprehensive programmes, and aerobic training alone compared to aerobic plus resistance programmes. Using univariate meta-regression, there was evidence of significant association between location of trial and length of longest follow-up on exercise capacity. AUTHORS' CONCLUSIONS: Due to few randomised participants and typically short-term follow-up, the impact of ExCR on all-cause mortality or serious adverse events for people with AF is uncertain. ExCR likely improves AF-specific measures including reduced AF recurrence, symptom burden, and episode duration, as well as the mental components of HRQoL. ExCR may improve AF symptom severity, episode frequency, and VO2peak. Future high-quality RCTs are needed to assess the benefits of ExCR for people with AF on patient-relevant outcomes including AF symptom severity and burden, AF recurrence, AF-specific quality of life, and clinical events such as mortality, readmissions, and serious adverse events. High-quality trials are needed to investigate how AF subtype and clinical setting (i.e. primary and secondary care) may influence ExCR effectiveness.

Safety and Patient Experience With Early Mobilization After Transcatheter Aortic Valve Implantation: A Randomized Trial.

BACKGROUND: Immobilization after transcatheter aortic valve replacement (TAVR) is the standard treatment for preventing access-related complications. However, the length of bed rest varies, and possible complications and patient experience remain unexplored. OBJECTIVE: In this pilot study, our aim was to investigate safety and efficacy after bed rest after TAVR. METHODS: This single-center randomized trial included 298 patients. Patients were randomized to standard 6 hours (n = 149) or 3 hours (n = 149) of bed rest after TAVR. The primary safety endpoint was a composite of access-related bleeding (Bleeding Academic Research Consortium type ≥ 2), hematoma (>5 cm), pseudoaneurysm, and vascular complications requiring intervention. The primary efficacy endpoint was patient-reported back pain, rated ≥6 on a numeric rating scale 24 hours post procedure. The secondary endpoints were the individual components of the primary safety endpoint, patient-reported pain, urination problems, and comfort. RESULTS: The primary safety endpoint occurred in 14 (9.4%) and 12 (8.1%) patients in the 6-hour and 3-hour immobilization groups, respectively (risk ratio, 0.86 [95% confidence interval, 0.41-1.79]; P = .68). There were no significant differences in individual bleeding or vascular complication endpoints. Patients with 3 hours of bed rest reported less back pain (P < .001), fewer urination problems (P < .001), and better comfort (P < .001) than patients with 6 hours of bed rest. CONCLUSIONS: Mobilization as early as 3 hours after TAVR was shown to be safe, not resulting in a higher rate of bleeding or vascular complications as compared with 6 hours of bed rest. However, there was a difference in patient-reported back pain, urination problems, and comfort, favoring early mobilization.

The rise and fall of a social support intervention feasibility trial targeting loneliness in patients with cardiac disease - lessons learned and future perspectives.

BACKGROUND: One of the psychosocial factors recognized for its positive impact on health outcomes among patients with heart disease, is social support provided by network members. However, an increasing number of patients report to experience loneliness. This study addresses the gap in research on the feasibility of an individually structured social support intervention targeting patients treated for cardiac disease who experience loneliness. METHOD: A feasibility trial of a 6-month social support intervention targeted patients treated for cardiac disease who experienced loneliness. The intervention involved providing the patient with an informal caregiver, either a person from the patient's social network or a peer, in the long-term rehabilitation phase. Furthermore, the intervention included nurse consultations and motivational text messages. Feasibility was assessed in terms of acceptability and adherence. RESULTS: During October 2022-July 2023, n = 464 patients were screened for loneliness and 28 (6.0%) screened positive of which 17 (60.7%) accepted to be contacted and receive additional information about the social support intervention. Of these, 2 (11.8%) accepted participation. The low recruitment rate did not meet the predetermined acceptability criterion of 25%. CONCLUSION: This individually structured social support intervention targeting patients treated for cardiac disease who experience loneliness was non-feasible. The study highlights the complexities of engaging lonely patients in a social support intervention program and contributes with valuable insights for future research aiming to develop effective social support interventions tailored to the needs of cardiac patients who experience loneliness. TRIAL REGISTRATION: The trial is registered on clinicaltrials.gov (NCT05503810) 18.08.2022.

Patient-reported outcomes, sociodemographic and clinical factors are associated with 1-year mortality in patients with ischemic heart disease-findings from the DenHeart cohort study.

PURPOSE: In patients with ischemic heart disease, the objectives were (1) to explore associations between patient-reported outcomes, sociodemographic, and clinical factors at discharge and 1-year all-cause mortality and (2) to investigate the discriminant predictive performance of the applied patient-reported outcome instruments on 1-year all-cause mortality. METHODS: Data from the Danish national DenHeart cohort study were used. Eligible patients (n = 13,476) were invited to complete a questionnaire-package, of which 7167 (53%) responded. Questionnaires included the 12-item Short form health survey (SF-12), Hospital anxiety and depression scale (HADS), EQ-5D, HeartQoL, Edmonton symptom assessment scale (ESAS), and ancillary questions on, e.g., social support. Clinical and demographic characteristics were obtained from registers, as were data on mortality. Comparative analyses were used to investigate differences in patient-reported outcomes. Mortality associations were explored using multifactorially adjusted Cox regression analyses. Predictive performance was analyzed using receiver operating characteristics (ROC). RESULTS: Patient-reported outcomes at discharge differed among those alive versus those deceased at one year, e.g., depression (HADS-Depression ≥ 8) 19% vs. 44% (p < 0.001). Associations with 1-year mortality included feeling unsafe about returning home from the hospital; hazard ratio (HR) 2.07 (95% CI 1.2-3.61); high comorbidity level, HR 3.6 (95% CI 2.7-4.8); and being unmarried, HR 1.60 (95% CI 1.33-1.93). Best predictive performance was observed for SF-12 physical component summary (Area under the curve (AUC) 0.706). CONCLUSION: Patient-reported health, sociodemographic, and clinical factors are associated with 1-year mortality. We propose systematic screening with robust predictive tools to identify patients at risk and healthcare initiatives to explore and offer effective treatment to modify patient-reported health indicators.

Prognostic value of a brief loneliness questionnaire for patients with coronary heart disease: Proposal for a prediction model.

BACKGROUND: In patients with coronary heart disease (CHD), loneliness is associated with increased risk of morbidity and mortality. No predictive tool is available to detect patients who are influenced by loneliness to a degree that impacts mortality. AIM: To: (i) propose a prediction model that detects patients influenced by loneliness to a degree that increases one-year all-cause mortality, (ii) evaluate model classification performance of the prediction model, and (iii) investigate potential questionnaire response errors. METHOD: A cohort of patients with CHD (n = 7169) responded to a national cross-sectional survey, including two questions on loneliness. Information on cohabitation and follow-up information on one-year all-cause mortality were obtained from national registers. Prediction model development was based on the prognostic values of item responses in the questionnaire on loneliness and of cohabitation, evaluated with Cox-proportional Hazards Ratio (HR). Item responses which significantly predicted one-year mortality were included in the high-risk loneliness (HiRL) prediction model. Sensitivity, specificity and likelihood ratio were calculated to evaluate model classification performance. Sources of response errors were evaluated using verbal probing technique in an additional cohort (n = 7). The TRIPOD checklist has been used to ensure transparent reporting. RESULTS: Two item responses significantly predicted one-year mortality HR = 2.24 (95%CI = 1.24-4.03) and HR = 2.65 (95%CI = 1.32-5.32) and were thus included in the model. Model classification performance showed a likelihood ratio of 1.89. Response error was evaluated as low. CONCLUSION: Based on the prognostic value in a loneliness questionnaire, a prediction model suitable to screen patients with CHD for high-risk loneliness was suggested. RELEVANCE TO CLINICAL PRACTICE: The HiRL prediction model is a short and easy-to-use screening tool that offers clinical staff to identify patients with CHD who are influenced by loneliness to a degree that impacts mortality. However, further evaluation of model performance and questionnaire validation is recommended before integrating the model into clinical practice.

Am I going to die now? Experiences of hospitalisation and subsequent life after being diagnosed with aortic dissection.

Aortic dissection is a life-threatening condition with mortality up to 75%. In the acute phase, patients are constrained with total bed rest until pain relief and blood pressure has been stabilised. Some need surgery. Aortic dissection is associated with anxiety and poor health-related quality of life. However, no study has explored the experience of living through aortic dissection. The aim of this study was to explore the patient experience of living through aortic dissection. Data were collected in interviews with 10 patients who lived through aortic dissection. Data were gathered and analysed using a phenomenological approach. The qualitative analysis revealed four themes; 'Am I going to die now? - the existential turning point when diagnosed with life-threatening aortic dissection', 'compromised integrity during admission - experiences of hospitalisation', 'Signals from my body - a new awareness of the body after discharge', 'What can I do? - uncertainties about physical activity in daily life posthospitalisation'. Experiences of aortic dissection are a life-threatening and overwhelming existential life situation which includes a period of constraining hospitalisation and experiences a compromised integrity. Patients have substantial concerns regarding body signals and a constantly uncertainty about what kind of activity level they can sustain which affect their mental well-being and their daily life. These findings contribute to understanding and elaborating a more nuanced description of being diagnosed with aortic dissection, which is essential when planning high-quality treatment and care, developing sufficient follow-up and preventing adverse events.

Educational interventions to improve outcomes in patients with atrial fibrillation-a systematic review.

BACKGROUND: Atrial fibrillation (AF) is an emerging epidemic associated with poor mental health and quality of life, as well as morbidity and mortality. Whilst other cardiovascular conditions have demonstrated positive outcomes from educational programmes, this approach is not well integrated in clinical practice in patients with AF. Though evidence in this area is mounting, a thorough overview seems to be lacking. AIM: To assess benefits and harms of educational interventions compared with no intervention in adults with AF. METHOD: A systematic review and meta-analysis were performed including the outcomes: Serious adverse events (mortality and readmission), mental health (anxiety and depression), physical capacity, quality of life and self-reported incidence of symptoms of AF. PubMed, Embase, CINAHL, Cochrane Library and PsycINFO were searched between June and august 2018. Data extraction and quality assessment were performed independently by two reviewers. The Cochrane Risk of Bias tool was applied for the randomised controlled trials and the Amstar Checklist for the systematic reviews. RESULTS: Eight randomised controlled trials and one non-randomised interventional study were included, with a total of 2388 patients. Comparing with controls patient education was associated with a reduction in: Serious adverse events (Risk Ratio 0.78, CI 95% 0.63-0.97), anxiety with a mean difference of -0.62 (CI 95% -1.21, -0.04) and depression with a mean difference of -0.74 (CI 95% -1.34, -0.14). Health-related quality of life and physical capacity was found to increase after patient education, yet, only one study found statistically significant differences between groups. No differences were observed with regards to self-reported incidence of symptoms of AF. CONCLUSIONS: Educational interventions significantly decrease the number of serious adverse events in patients with AF and seem to have a positive impact on mental health and self-reported quality of life. However, the evidence is limited, and more studies are warranted.

A place of understanding: Patients' lived experiences of participating in a sexual rehabilitation programme after heart disease.

AIMS AND OBJECTIVES: The aim of this project was to explore the lived experience of participating in a nonpharmacological sexual rehabilitation programme. BACKGROUND: In the healthcare system, patients are important stakeholders, and their experience and knowledge are essential to include when evaluating rehabilitation programmes. Patient experiences with participating in sexual rehabilitation for cardiovascular patients have not yet been investigated. METHODS: Ten qualitative interviews were conducted with male patients from a randomised controlled trial investigating the effect of a 12-week rehabilitation programme focusing on sexuality. The analysis was inspired by Paul Ricoeur's theory of interpretation. Analysis consisted of three levels: (i) naive reading, (ii) structural analysis and (iii) critical interpretation and discussion. The theoretical framework reflects aspects of behavioural theory of social cognitive theory developed by Albert Bandura and his concept of self-efficacy. RESULTS: The findings are presented as themes extracted from the structural analysis and interpreted in the critical interpretation and express the way in which cardiovascular patients experience participating in a sexual rehabilitation programme. Three themes were identified reflecting the intervention to be a special place of understanding, describing the intervention as a supporting atmosphere and finally expressing the intervention as empowering sexuality. CONCLUSIONS: Participating in the sexual rehabilitation programme was experienced as efficient, valuable, motivating and safe, but dependent on a professional setting. The intervention developed participants' self-efficacy with regard to their sexual performance and relationship. RELEVANCE TO CLINICAL PRACTICE: The findings highlight the importance of a professional setting including certain competencies such as humour and professional skills when handling the after-care of cardiovascular patients with sexual problems.

Subgroup Differences and Determinants of Patient-Reported Mental and Physical Health in Patients With Ischemic Heart Disease: Results From the DenHeart Study.

BACKGROUND: A growing population is living with ischemic heart disease (IHD). Patient-reported outcomes (PROs) are reliable prognostic tools. Studies exploring PROs are needed to identify vulnerable patients and guide targeted healthcare strategies. OBJECTIVES: The aims of this study were to (i) describe PROs at hospital discharge across 3 diagnostic subgroups: (1) chronic IHD/stable angina, (2) non-ST-elevation myocardial infarction (non-STEMI)/unstable angina, and (3) ST-elevation myocardial infarction (STEMI), and (ii) examine determinants for PROs at hospital discharge in patients with IHD. METHODS: This study included a national cohort with register-data linkage including 14 115 adults with IHD discharged from Danish heart centers. Eligible patients (n = 13 476) were invited to complete a questionnaire, and 7 167 (53%) responded. Questionnaires included the Medical Outcome Study Short-Form 12, the Hospital Anxiety and Depression Scale, EuroQoL, HeartQoL, the Edmonton Symptom Assessment Scale, and ancillary questions. Sociodemographic and clinical characteristics were obtained from national registers. Student t test, χ test, and adjusted linear and logistic regression analyses were conducted to investigate subgroup differences, and adjusted linear and logistic regression analyses were conducted to explore determinants for PROs. RESULTS: Statistically significant subgroup differences were found, with groups reporting worst to best scores for most of PROs being as follows: chronic IHD/stable angina, non-STEMI/unstable angina, and STEMI. Symptoms of anxiety were highly prevalent in the non-STEMI/unstable angina group, with 33.8% exceeding a Hospital Anxiety and Depression Scale-Anxiety cutoff score indicating a possible anxiety disorder. Determinants for worse PROs included female sex, lower educational level, obesity, and poor physical fitness. CONCLUSIONS: Significant differences in PROs across IHD subgroups were observed and determinants for poor outcomes suggested. Results may guide differentiated care initiatives and resource allocation for preventative strategies.

Protocol for a feasibility randomized trial of a social support intervention plus usual care versus usual care, targeting patients treated for cardiac disease who experience loneliness.

INTRODUCTION: In patients treated for cardiac disease, loneliness is known to contribute negatively to health behavior, health outcome, and increase risk of cardiac and all-cause mortality. Even so, in health care research, social support interventional studies targeting patients who experience loneliness are lacking. AIM: To determine the feasibility of an individually structured social support intervention targeting patients treated for cardiac disease who experience loneliness. DESIGN: A feasibility study based on randomized clinical trial design with 1:1 randomization to a 6-month social support program, plus usual care (intervention) versus usual care, (i.e., regular guidelines-based follow-up). INTERVENTION: Patients classified as high risk lonely according to the High Risk Loneliness tool will be provided with an informal caregiver in the 6 months rehabilitation phase following cardiac disease treatment. The informal caregiver will be designated by the patient from the existing social network or a peer, depending on patients' preferences. The core content of the intervention is through nurse consultations at baseline and 1, 3, and 6 months, to enhance and reinforce the informal caregiver's competences to be a social support resource. The theoretical framework of the nurse consultations will be based on middle-range theory of self-care. OUTCOME: Feasibility will be evaluated in terms of acceptability and adherence according to predefined feasibility criteria. The preliminary effect of the intervention on patient-reported outcomes, health behaviors, and health outcomes will be evaluated in the intervention and the control group at baseline and 1, 3, 6, and 12 months. DISCUSSION: The present study will contribute with knowledge on how to implement a feasible social support intervention targeting patients treated for cardiac disease who experience loneliness and, furthermore, investigate the preliminary effect on health behavior and health outcome in the early rehabilitation period. TRIAL REGISTRATION: The trial is registered on clinicaltrials.gov (NCT05503810) 18.08.2022.

The association of electronic health literacy with behavioural and psychological coronary artery disease risk factors in patients after percutaneous coronary intervention: a 12-month follow-up study.

Aims: Fundamental roadblocks, such as non-use and low electronic health (eHealth) literacy, prevent the implementation of eHealth resources. The aims were to study internet usage for health information and eHealth literacy in patients after percutaneous coronary intervention (PCI). Further, we aimed to evaluate temporal changes and determine whether the use of the internet to find health information and eHealth literacy were associated with coronary artery disease (CAD) risk factors at the index admission and 12-month follow-up of the same population. Methods and results: This prospective longitudinal study recruited 2924 adult patients with internet access treated by PCI in two Nordic countries. Assessments were made at baseline and 12-month follow-up, including a de novo question Have you used the internet to find information about health?, the eHealth literacy scale, and assessment of clinical, behavioural, and psychological CAD risk factors. Regression analyses were used. Patients' use of the internet for health information and their eHealth literacy were moderate at baseline but significantly lower at 12-month follow-up. Non-users of the internet for health information were more often smokers and had a lower burden of anxiety symptoms. Lower eHealth literacy was associated with a higher burden of depression symptoms at baseline and lower physical activity and being a smoker at baseline and at 12-month follow-up. Conclusion: Non-use of the internet and lower eHealth literacy need to be considered when implementing eHealth resources, as they are associated with behavioural and psychological CAD risk factors. eHealth should therefore be designed and implemented with high-risk CAD patients in mind.

Symptoms in the acute phase of SARS-CoV-2 infection among Danish children aged 0-14 years.

Objectives: To investigate the prevalence and burden of proxy-reported acute symptoms in children in the first 4 weeks after detection of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, and factors associated with symptom burden. Methods: Nationwide cross-sectional survey using parental proxy reporting of symptoms associated with SARS-CoV-2 infection. In July 2021, a survey was sent to the mothers of all Danish children aged 0-14 years with a positive SARS-CoV-2 polymerase chain reaction (PCR) test between January 2020 and July 2021. The survey included 17 symptoms associated with acute SARS-CoV-2 infection and questions about comorbidities. Results: Of 38,152 children with a positive SARS-CoV-2 PCR test, 10,994 (28.8%) mothers responded. The median age was 10.2 (range 0.2-16.0) years and 51.8% were male. Among participants, 54.2% (n=5957) reported no symptoms, 43.7% (n=4807) reported mild symptoms, and 2.1% (n=230) reported severe symptoms. The most common symptoms were fever (25.0%), headache (22.5%) and sore throat (18.4%). Asthma {odds ratio (OR) 1.91 [95% confidence interval (CI) 1.57-2.32) and OR 2.11 (95% CI 1.36-3.28)}, allergy [OR 1.31 (95% CI 1.14-1.52) and OR 1.70 (95% CI 1.18-2.46], eczema [OR 1.43 (95% CI 1.20-1.71) and OR 2.03 (95% CI 1.38-2.97)] and OCD/anxiety/depression [OR 2.06 (95% CI 1.39-3.06) and OR 3.79 (95% CI 1.80-7.97)] were associated with reporting a higher symptom burden [values indicate outcomes reporting three or more acute symptoms (upper quartile) and reporting a severe symptom burden, respectively]. The highest prevalence of symptoms was found among children aged 0-2 and 12-14 years. Conclusions: Among SARS-CoV-2-positive children aged 0-14 years, approximately half reported no acute symptoms within the first 4 weeks after a positive PCR test. Most symptomatic children reported mild symptoms. Several comorbidities were associated with reporting a higher symptom burden.

Who Cares? Perception of Loneliness in Patients Treated for Coronary Heart DiseaseHvem bekymrer sig? Oplevelsen af ensomhed hos patienter med iskæmisk hjertesygdom.

Social support is known to be essential to cope with the physical and psychological aftermath following coronary heart disease treatment. Consequently, patients experiencing loneliness may be placed in a vulnerable situation. The aim of this study was to provide insight into the nuances and complexity of loneliness and its impact on health behaviour in the early rehabilitation period following treatment. The study used a hermeneutic philosophical approach. Patients classified as lonely were interviewed in either a focus group (n = 7) or in an individual interview (n = 10). We analysed the empirical material using inductive content analysis. The analysis illuminated various dimensions of patients' perceived loneliness; 'Loneliness as an emotional pain', 'A changed, but unmet need for social support' and 'Striving for symmetry in relationships'. Loneliness negatively influenced patients' ability to adapt to the critical event and manage health behaviour changes. Insight into the mechanisms that aggravate loneliness may inform future social support interventions. Social støtte er beskrevet som essentiel i forbindelse med håndteringen af de fysiske og psykiske følger af iskæmisk hjertesygdom. Derfor kan patienter som oplever ensomhed være i en særlig sårbar situation. Formålet med dette kvalitative studie var at opnå en nuanceret indsigt i patients oplevelse af ensomhed, samt hvordan ensomhed influerer på sundhedsadfærd i den tidlige rehabiliteringsperiode efter behandlingen for iskæmisk hjertesygdom. I studiet havde vi en hermeneutisk filosofisk tilgang. Patienter klassificeret som ensomme blev interviewet enten individuelt (n = 10) eller i fokusgruppe (n = 7). Vi analyserede det empiriske materiale med induktiv indholdsanalyse. Analysen tydeliggjorde forskellige dimensioner af patienternes oplevede ensomhed: "Ensomhed som en emotionel smerte", "Et ændret, men ikke imødekommet behov for social støtte", Stræben efter symmetri i relationer". Ensomhed havde en negativ indflydelse på patienternes mulighed for at håndtere den kritiske hændelse og på sundhedsadfærd. En øget indsigt i de mekanismer som forværrer ensomhed, har relevans ved udarbejdelsen af fremtidige sociale støtteinterventioner.

One size does not fit all: A qualitative study exploring preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease.

AIM: To explore preferences and barriers towards the design of a loneliness reduction intervention in patients treated for coronary heart disease who experience loneliness. DESIGN: A qualitative study using patient involvement methodology. METHODS: Seventeen patients participated in either focus groups or individual interview sessions. The interview guide was based on patient involvement methodology. Interviews were analysed using deductive content analysis. RESULTS: Four overall findings emerged as follows: (a) An intervention involving a social network member must comply with patients perceived social norms; (b) An intervention involving a peer provides benefits from reciprocity and shared experiences, but also requires surplus mental energy; (c) The history of an existing relationship can act as both provider and barrier for confidentiality and (d) Start-up, timeframe and structure of the intervention should be individually tailored to the patient's preferences. Findings illuminated preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease.

Health Literacy and Risk Factors for Coronary Artery Disease (From the CONCARDPCI Study).

In the setting of established coronary artery disease (CAD), lower health literacy is associated with poor outcomes. The aim of this study was to determine whether health literacy at the index admission was associated with established CAD risk factors and with changes in CAD risk factors from baseline until 6 months after percutaneous coronary intervention (PCI). A multicenter cohort study recruited 3,417 patients aged ≥18 years who were treated with PCI. Assessments were made at the index admission for PCI and at 6-month follow-up, including 4 of the 9 scales from the Health Literacy Questionnaire, an assessment of behavioral risk factors and psychologic risk factors for CAD. In this large study, key aspects of health literacy were associated with behavioral and psychologic risk factors for CAD. For each 1-unit higher score on the health literacy scales, weekly physical activity was 12 to 20 intensity-adjusted minutes higher, and the odds of being a nonsmoker were 24% to 72% higher. The risk factors for CAD improved from baseline to 6-month follow-up, although most were not significantly associated with health literacy. Still, patients with lower health literacy scores were more likely to report a greater reduction in depression symptoms from baseline to 6-month follow-up. In conclusion, the study provides evidence that several aspects of health literacy are associated with risk factors for CAD. These results serve as a reminder to healthcare teams to consider health literacy challenges in connection with secondary prevention care.

Acute symptoms in SARS-CoV-2 positive adolescents aged 15-18 years - Results from a Danish national cross-sectional survey study.

Background: The purpose of this study was to investigate prevalence of self-reported symptom burden during the acute phase of SARS-CoV-2 infection and associated factors including sex differences. Methods: All Danish adolescents aged 15-18 years with laboratory confirmed SARS-CoV-2 infection between January 2020 and July 2021 were invited to participate. A survey covered the initial four weeks of SARS-CoV-2 infection and included questions regarding 17 symptoms associated with acute COVID-19, symptom burden and medical history. Statistical analyses included descriptive statistics and logistic regression. Findings: A total of 24,315 adolescents with SARS-CoV-2 infection were invited and 6630 (27.3%) completed the questionnaire. The median age was 17.6 years, and 58.4% (n = 3873) were female. No symptoms were reported by 33.8% (n = 2241), mild perceived symptom burden by 57.2%(n = 3775), and severe symptom burden by 9.0 % (n = 594). Two thirds (n = 2999) of the symptomatic participants reported a symptom duration of 1-10 days. The most prevalent symptoms included headaches 39.2% (n = 2597), a reduced sense of smell 36.2% (n = 2398), cough 31.6% (n = 2093), sore throat 31.1% (n = 2063), and a reduced sense of taste 31.1% (n = 2062). Adolescents at the age of 18 years had higher odds of reporting ≥6 symptoms OR1.47 (95%CI, 1.23-1.76), p < 0.0001 and adolescents 18+ years old had higher odds of reporting a severe symptom burden OR1.98 (95%CI, 1.43-2.73) compared to the 15years old adolescents. A history of OCD/anxiety/depression was associated with reporting ≥6 symptoms OR 1.67 (95%CI, 1.34-2.09), p < 0.0001 and a history of allergy and OCD/anxiety/depression reporting severe symptom burden OR 1.64 (95%CI, 1.35-1.99), p < 0.0001 and OR 1.75 (95%CI, 1.28-2.36), p = 0.0004. Females reported more symptoms than males; median of three (IQR 0-6) vs. a median of two (IQR 0-4) symptoms, p < 0.0001. Interpretation: Two in three experienced symptoms and the majority reported mild symptom burden. Headache, a reduced sense of smell and taste, cough and sore throat were most common. Female sex, asthma and previous Epstein-Barr virus were associated with more symptoms and higher symptom burden. Funding: The study was funded by the AP Møller Foundation. The research was investigator initiated. The study funder played no role in the study.

Long COVID symptoms in SARS-CoV-2-positive adolescents and matched controls (LongCOVIDKidsDK): a national, cross-sectional study.

BACKGROUND: Many adolescents have been affected by the COVID-19 pandemic either directly by being infected with the virus or indirectly by lockdowns and restrictions influencing normal living. We aimed to investigate health, including symptoms of long COVID, in adolescents (aged 15-18 years) who tested positive for SARS-CoV-2 compared with a control group. METHODS: LongCOVIDKidsDK was a national, cross-sectional study carried out in Denmark, which included SARS-CoV-2-positive adolescents and matched controls. All Danish adolescents aged 15-18 years with a positive SARS-CoV-2 test during the period Jan 1, 2020, to July 12, 2021, and a control group matched (1:4) by age and sex were sent a survey from July 20, 2021. Participants had until Sept 15, 2021, to respond. Symptoms associated with COVID-19, school attendance, and health-related quality of life were investigated using ancillary questions and validated questionnaires (Paediatric Quality of Life Inventory [PedsQL] and Children's Somatic Symptoms Inventory-24 [CSSI-24]). Statistical analyses included descriptive statistics and logistic regression. This study is registered at ClinicalTrials.gov, NCT04786353. FINDINGS: 24 315 adolescents with a positive SARS-CoV-2 test (case group) and 97 257 matched controls were invited to participate. 3013 matched controls were excluded because of suspected SARS-CoV-2 infection. 6630 (27·3%) responded in the case group and 21 640 (22·3%) responded and were eligible to participate in the control group. Across both groups, median age was 17·6 years (IQR 16·4-18·5), 16 277 (57·6%) of 28 270 responders were female, and 11 993 (42·4%) were male. Participants in the case group had greater odds of having at least one long COVID symptom lasting at least 2 months compared with the control group (3159 [61·9%] vs 12 340 [57·0%], odds ratio 1·22 [95% CI 1·15-1·30]; p<0·0001). Participants in the case group reported significantly lower symptom scores (ie, less somatic distress) on the CSSI-24 than in the control group: mean 10·7 (SD 11·4, median 7·0 [IQR 2·0-15·0]) versus 11·9 (10·6, 9·0 [4·0-17·0]; p<0·0001). Participants in the case group had better quality of life scores on the PedsQL than in the control group: physical functioning mean score 88·7 (SD 13·9, median 93·8 [IQR 84·4-100·0]) versus 86·5 (14·3, 90·6 [81·3-96·9]; p<0·0001); emotional functioning 77·1 (20·3, 80·0 [65·0-95·0]) versus 71·7 (21·4, 75·0 [60·0-90·0]; p<0·0001); social functioning 93·1 (12·5, 100·0 [90·0-100·0]) versus 88·4 (16·2, 95·0 [80·0-100·0]; p<0·0001); and school functioning 66·9 (22·5, 65·0 [60·0-85·0]) versus 62·9 (22·1, 65·0 [50·0-80·0]; p<0·0001). More participants in the case group than in the control group reported 16 or more sick days (1205 [18·2%] vs 2518 [11·6%]; p<0·0001) and 16 or more days of school absence (695 [10·5%] vs 1777 [8·2%]; p<0·0001). INTERPRETATION: Participants with SARS-CoV-2-positive tests had more long-lasting symptoms and sick leave, whereas participants in the control group had more short-lasting symptoms and worse quality of life. Knowledge of long COVID in adolescents is important to guide clinical recognition and management of this condition. FUNDING: AP Møller and Chastine McKinney Møller Foundation.

Long COVID symptoms in SARS-CoV-2-positive children aged 0-14 years and matched controls in Denmark (LongCOVIDKidsDK): a national, cross-sectional study.

BACKGROUND: After the acute phase of SARS-CoV-2 infection, children can develop long COVID symptoms. We aimed to investigate the prevalence of long-lasting symptoms, the duration and intensity of symptoms, quality of life, number of sick days and absences from daycare or school, and psychological and social outcomes in children aged 0-14 years who had been infected with SARS-CoV-2 relative to controls with no history of SARS-CoV-2 infection. METHODS: A nationwide cross-sectional study was conducted including children with a confirmed SARS-CoV-2-positive PCR test (cases) and matched controls from Danish national registers. A survey was sent to mothers (proxy reporting) of children aged 0-14 years who had had a positive SARS-CoV-2 test between Jan 1, 2020, and July 12, 2021, and a control group matched (1:4) by age and sex. The survey included the Pediatric Quality of Life Inventory (PedsQL) and the Children's Somatic Symptoms Inventory-24 (CSSI-24) to capture current overall health and wellbeing, and ancillary questions about the 23 most common long COVID symptoms. Descriptive statistics and logistic regression analysis were used. Clinically relevant differences were defined as those with a Hedges'g score greater than 0·2. This study is registered at ClinicalTrials.gov (NCT04786353). FINDINGS: Responses to the survey were received from 10 997 (28·8%) of 38 152 cases and 33 016 (22·4%) of 147 212 controls between July 20, 2021, and Sept 15, 2021. Median age was 10·2 years (IQR 6·6-12·8) in cases and 10·6 years (6·9-12·9) in controls. 5267 (48·2%) cases and 15 777 (48·3%) controls were female, and 5658 (51·8%) cases and 16 870 (51·7%) controls were male. Cases had higher odds of reporting at least one symptom lasting more than 2 months than did controls in the 0-3 years age group (478 [40·0%] of 1194 vs 1049 [27·2%] of 3855; OR 1·78 [95% CI 1·55-2·04], p<0·0001), 4-11 years age group (1912 [38·1%] of 5023 vs 6189 [33·7%] of 18 372; 1·23 [1·15-1·31], p<0·0001), and 12-14 years age group (1313 [46·0%] of 2857 vs 4454 [41·3%] of 10 789; 1·21 [1·11-1·32], p<0·0001). Differences in CSSI-24 symptom scores between cases and controls were statistically significant but not clinically relevant. Small clinically relevant differences in PedsQL quality-of-life scores related to emotional functioning were found in favour of cases in the children aged 4-11 years (median score 80·0 [IQR 65·0-95·0]) in cases vs 75·0 [60·0-85·0] in controls; p<0·0001) and 12-14 years (90·0 [70·0-100·0] vs (85·0 [65·0-95·0], p<0·0001). PedsQL social functioning scores were also higher in cases (100·0 [90·0-100·0] than controls (95·0 [80·0-100·0]) in the 12-14 years age group (p<0·0001; Hedges g>0·2). INTERPRETATION: Compared with controls, children aged 0-14 years who had a SARS-CoV-2 infection had more prevalent long-lasting symptoms. There was a tendency towards better quality-of-life scores related to emotional and social functioning in cases than in controls in older children. The burden of symptoms among children in the control group requires attention. Long COVID must be recognised and multi-disciplinary long COVID clinics for children might be beneficial.

Rethinking rehabilitation after percutaneous coronary intervention: a protocol of a multicentre cohort study on continuity of care, health literacy, adherence and costs at all care levels (the CONCARDPCI).

INTRODUCTION: Percutaneous coronary intervention (PCI) aims to provide instant relief of symptoms, and improve functional capacity and prognosis in patients with coronary artery disease. Although patients may experience a quick recovery, continuity of care from hospital to home can be challenging. Within a short time span, patients must adjust their lifestyle, incorporate medications and acquire new support. Thus, CONCARDPCI will identify bottlenecks in the patient journey from a patient perspective to lay the groundwork for integrated, coherent pathways with innovative modes of healthcare delivery. The main objective of the CONCARDPCI is to investigate (1) continuity of care, (2) health literacy and self-management, (3) adherence to treatment, and (4) healthcare utilisation and costs, and to determine associations with future short and long-term health outcomes in patients after PCI. METHODS AND ANALYSIS: This prospective multicentre cohort study organised in four thematic projects plans to include 3000 patients. All patients undergoing PCI at seven large PCI centres based in two Nordic countries are prospectively screened for eligibility and included in a cohort with a 1-year follow-up period including data collection of patient-reported outcomes (PRO) and a further 10-year follow-up for adverse events. In addition to PROs, data are collected from patient medical records and national compulsory registries. ETHICS AND DISSEMINATION: Approval has been granted by the Norwegian Regional Committee for Ethics in Medical Research in Western Norway (REK 2015/57), and the Data Protection Agency in the Zealand region (REG-145-2017). Findings will be disseminated widely through peer-reviewed publications and to patients through patient organisations. TRIAL REGISTRATION NUMBER: NCT03810612.
