Validity of a smartwatch for detecting atrial fibrillation in patients after heart valve surgery: a prospective observational study.

OBJECTIVES: Atrial fibrillation (AF) is a common early arrhythmia after heart valve surgery that limits physical activity. We aimed to evaluate the criterion validity of the Apple Watch Series 5 single-lead electrocardiogram (ECG) for detecting AF in patients after heart valve surgery. DESIGN: We enrolled 105 patients from the University Hospital of North Norway, of whom 93 completed the study. All patients underwent single-lead ECG using the smartwatch three times or more daily on the second to third or third to fourth postoperative day. These results were compared with continuous 2-4 days ECG telemetry monitoring and a 12-lead ECG on the third postoperative day. RESULTS: On comparing the Apple Watch ECGs with the ECG monitoring, the sensitivity and specificity to detect AF were 91% (75, 100) and 96% (91, 99), respectively. The accuracy was 95% (91, 99). On comparing Apple Watch ECG with a 12-lead ECG, the sensitivity was 71% (62, 100) and the specificity was 92% (92, 100). CONCLUSION: The Apple smartwatch single-lead ECG has high sensitivity and specificity, and might be a useful tool for detecting AF in patients after heart valve surgery.

Discharge Information About Adverse Drug Reactions Indicates Lower Self-Reported Adverse Drug Reactions and Fewer Concerns in Patients After Percutaneous Coronary Intervention.

AIM: There are discrepancies between the information patients desire about adverse drug reactions (ADRs) and the information they receive from healthcare providers; this is an impediment to shared decision-making. This study aimed to establish whether patients received information about ADRs resulting from prescribed pharmacotherapy, before hospital discharge, after percutaneous coronary intervention (PCI) and to determine whether receiving information about ADRs was associated with incidence of self-reported ADRs or concerns related to prescribed pharmacotherapy. METHODS: CONCARDPCI, a prospective multicentre cohort study including 3,417 consecutive patients after PCI, was conducted at seven high-volume referral PCI centres in two Nordic countries. Clinical data were collected from patients' medical records and national quality registries. Patient-reported outcome measures were registered 2 months (T1), 6 months (T2), and 12 months (T3) after discharge. Covariate-adjusted logistic regression yielded adjusted odds ratios (aORs) with 95% confidence intervals (CIs). RESULTS: At discharge, 38% of participants had been informed about potential ADRs. For these patients, the incidence of self-reported ADRs was significantly lower at T1 (aOR 0.61, 95% CI 0.50-0.74; p<0.001), T2 (aOR 0.60, 95% CI 0.49-0.74; p<0.001), and T3 (aOR 0.57, 95% CI 0.46-0.71; p<0.001). Those who were not informed reported higher levels of concern about prescribed pharmacotherapy at all measuring points (p<0.001 for all comparisons). Those living alone (aOR 0.73, 95% CI 0.57-0.92; p=0.008), who were female (aOR 0.57, 95% CI 0.44-0.72; p<0.001), and with three or more versus no comorbidities (aOR 0.61, 95% CI 0.44-0.84; p=0.002) were less likely to receive information. CONCLUSION: A substantial proportion of patients were not informed about potential ADRs from prescribed pharmacotherapy after PCI. Patients informed about ADRs had lower incidences of self-reported ADRs and fewer concerns about prescribed pharmacotherapy.

The association between health-related quality of life, self-reported characteristics and 1- and 3-year mortality amongst cardiac patients with and without type 2 diabetes.

PURPOSE: The objectives amongst cardiac patients with and without type 2 diabetes were to (i) describe self-reported characteristics as health-related quality of life (HRQoL), health behaviour, body mass index (BMI) and physical shape and to (ii) investigate the association between self-reported characteristics and 1- and 3-year mortality. METHODS: Adult patients (≥ 18 years) discharged with a cardiac diagnosis were invited to participate in a national survey, DenHeart. Self-reported characteristics included HRQoL (EQ-5D-5L and HeartQol), health behaviour (alcohol and smoking), BMI and physical shape. Data were linked to national registries. The association between self-reported characteristics and 1- and 3-year mortality were investigated using the Cox Proportional Hazard Regression model, reported as hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: In total, 16,659 cardiac responders were included (n = 2,205 with type 2 diabetes, n = 14,454 without type 2 diabetes). Self-reported characteristics were worse amongst cardiac patients with type 2 diabetes compared to those without. After three years, the mortality rate was 14% amongst responders with diabetes and 7% amongst responders without type 2 diabetes (p ≤ 0.001). Better HRQoL was associated with a reduced risk of mortality amongst both groups. "Never been smoking" significantly reduced the risk of 1- and 3-year mortality amongst cardiac patients without diabetes, whereas good physical shape was associated with a reduced risk across both groups. CONCLUSION: HRQoL, health behaviour, BMI and physical shape are significantly worse amongst cardiac patients with type 2 diabetes. Better HRQoL was associated with a reduced risk of mortality amongst both groups, whereas other self-reported characteristics and the mortality risk varied.

Association Between Risk Factors and Readmission for Patients With Atrial Fibrillation Treated With Catheter Ablation: Results From the Nationwide DenHeart Study.

BACKGROUND: Because of high readmission rates for patients treated with ablation for atrial fibrillation (AF), there is great value in nurses knowing which risk factors make the largest contribution to readmission. OBJECTIVE: The aims of this study were to (1) describe potential risk factors at discharge and (2) describe the associations of risk factors with readmission from 60 days to 1 year after discharge. METHODS: Data from a national cross-sectional survey exploring patient-reported outcomes were used in conjunction with data from national health registers. This study included patients who had an ablation for AF during a single calendar year. The Hospital Anxiety and Depression Scale and questions on risk factors were included. Sociodemographic and clinical data were collected through registers, and readmissions were examined at 1 year. RESULTS: In total, 929 of 1320 (response rate, 70%) eligible patients treated with ablation for AF completed the survey. One year after ablation, there were 333 (36%) acute readmissions for AF and 401 (43%) planned readmissions for AF. Readmissions were associated with ischemic heart disease, anxiety, and depression. CONCLUSION: High observed readmission rates were associated with risk factors that included anxiety and depression. Postablation care should address these risk factors.

Sex Differences in Patient-Reported Outcomes in the Immediate Recovery Period After Resuscitation: Findings From the Cross-sectional DenHeart Survey.

BACKGROUND: A paucity of resuscitation studies have examined sex differences in patient-reported outcomes upon hospital discharge. It remains unclear whether male and female patients differ in health outcomes in their immediate responses to trauma and treatment after resuscitation. OBJECTIVES: The aim of this study was to examine sex differences in patient-reported outcomes in the immediate recovery period after resuscitation. METHODS: In a national cross-sectional survey, patient-reported outcomes were measured by 5 instruments: symptoms of anxiety and depression (Hospital Anxiety and Depression Scale), illness perception (Brief Illness Perception Questionnaire [B-IPQ]), symptom burden (Edmonton Symptom Assessment Scale [ESAS]), quality of life (Heart Quality of Life Questionnaire), and perceived health status (12-Item Short Form Survey). RESULTS: Of 491 eligible survivors of cardiac arrest, 176 (80% male) participated. Compared with male, resuscitated female reported worse symptoms of anxiety (Hospital Anxiety and Depression Scale-Anxiety score ≥8) (43% vs 23%; P = .04), emotional responses (B-IPQ) (mean [SD], 4.9 [3.12] vs 3.7 [2.99]; P = .05), identity (B-IPQ) (mean [SD], 4.3 [3.10] vs 4.0 [2.85]; P = .04), fatigue (ESAS) (mean [SD], 5.26 [2.48] vs 3.92 [2.93]; P = .01), and depressive symptoms (ESAS) (mean [SD], 2.60 [2.68] vs 1.67 [2.19]; P = .05). CONCLUSIONS: Between sexes, female survivors of cardiac arrest reported worse psychological distress and illness perception and higher symptom burden in the immediate recovery period after resuscitation. Attention should focus on early symptom screening at hospital discharge to identify those in need of targeted psychological support and rehabilitation.

The association between cardiac drug therapy and anxiety among cardiac patients: results from the national DenHeart survey.

BACKGROUND: Neuropsychiatric side effects of cardiac drugs such as nervousness, mood swings and agitation may be misinterpreted as symptoms of anxiety. Anxiety in cardiac patients is highly prevalent and associated with poor outcomes, thus an accurate identification is essential. The objectives were to: (I) describe the possible neuropsychiatric side effects of common cardiac drug therapies, (II) describe the use of cardiac drug therapy in cardiac patients with self-reported symptoms of anxiety compared to those with no symptoms of anxiety, and (III) investigate the association between the use of cardiac drug therapy and self-reported symptoms of anxiety. METHODS: DenHeart is a large national cross-sectional survey combined with national register data. Symptoms of anxiety were measured by the Hospital Anxiety and Depression Scale (HADS-A) on patients with ischemic heart disease, arrhythmia, heart failure and heart valve disease. Side effects were obtained from 'product summaries', and data on redeemed prescriptions obtained from the Danish National Prescription Registry. Multivariate logistic regression analyses explored the association between cardiac drug therapies and symptoms of anxiety (HADS-A ≥ 8). RESULTS: Among 8998 respondents 2891 (32%) reported symptoms of anxiety (HADS-A ≥ 8). Neuropsychiatric side effects were reported from digoxin, antiarrhythmics, beta-blockers, ACE-inhibitors and angiotensin receptor antagonists. Statistically significant higher odds of reporting HADS ≥ 8 was found in users of diuretics, lipid-lowering agents, nitrates, antiarrhythmics and beta-blockers compared to patients with no prescription. CONCLUSION: Some cardiac drugs were associated with self-reported symptoms of anxiety among patients with cardiac disease. Of these drugs neuropsychiatric side effects were only reported for antiarrhythmics and beta-blockers. Increased awareness about the possible adverse effects from these drugs are important.

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.

Long-term effects of cardiac rehabilitation after heart valve surgery - results from the randomised CopenHeartVR trial.

Aims. The CopenHeartVR trial found positive effects of cardiac rehabilitation (CR) on physical capacity at 4 months. The long-term effects of CR following valve surgery remains unclear, especially regarding readmission and mortality. Using data from he CopenHeartVR Trial we investigated long-term effects on physical capacity, mental and physical health and effect on mortality and readmission rates as prespecified in the original protocol. Methods. A total of 147 participants were included after heart valve surgery and randomly allocated 1:1 to 12-weeks exercise-based CR including a psycho-educational programme (intervention group) or control. Physical capacity was assessed as peak oxygen uptake (VO2 peak) measured by cardiopulmonary exercise testing, mental and physical health by Short Form-36 questionnaire, Hospital Anxiety and Depression Scale, and HeartQol. Mortality and readmission were obtained from hospital records and registers. Groups were compared using mixed regression model analysis and log rank test. Results. No differences in VO2 peak at 12 months or in self-assessed mental and physical health at 24 months (68% vs 75%, p = .120) was found. However, our data demonstrated reduction in readmissions in the intervention group at intermediate time points; after 3, 6 (43% vs 59%, p = .03), and 12 (53% vs 67%, p = .04) months, respectively, but no significant effect at 24 months. Conclusions. Exercise-based CR after heart valve surgery reduces combined readmissions and mortality up to 12 months despite lack of improvement in exercise capacity, physical and mental health long-term. Exercise-based CR can ensure short-term benefits in terms of physical capacity, and lower readmission within a year, but more research is needed to sustain these effects over a longer time period. These considerations should be included in the management of patients after heart valve surgery.

Cause of Death Among Cardiac Patients With and Without Anxiety.

BACKGROUND: Mental distress is reported internationally among patients with cardiac disease. A Danish survey found that 25% of patients with cardiac disease experienced symptoms indicating anxiety and that anxiety was associated with an increased risk of death. AIM: The aims of this study were to (1) compare cause of death patterns among deceased cardiac patients with anxiety to those without anxiety and (2) examine the association between anxiety symptoms and specific causes of death. METHODS: We used data from the DenHeart survey to evaluate symptoms of anxiety at discharge by using the Hospital Anxiety and Depression Scale. Data on mortality in the 3 years after discharge and cause of death according to International Classification of Diseases-10 classification came from national registers. Cause of death was compared between patients with and without anxiety using χ2 tests. The association between symptoms of anxiety and cause of death was investigated using logistic regression. RESULTS: Of 12 913 patients included, a total of 1030 (8%) died within 3 years. After 1 year, 4% of patients with anxiety symptoms had died versus 2% of patients without; after 3 years, the proportions were 9% versus 8%, respectively. Almost all died of natural causes irrespective of anxiety symptoms. No statistically significant differences were found regarding the cause of death between patients with and without anxiety. CONCLUSION: Despite higher mortality rates in patients with cardiac disease with anxiety symptoms, the pattern of cause of death was identical for patients with cardiac disease with and without anxiety symptoms. It seems that an acceleration of morbid processes leading to mortality is more likely than a difference in cause of death. However, further research is needed to better understand the behavioral and pathophysiological processes that cause the higher mortality seen among patients reporting symptoms of anxiety.

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.

Illness Perception After Heart Valve Surgery: Differences Among Men and Women.

BACKGROUND: Illness perception is composed of thoughts, ideas, and beliefs about illness, and a negative illness perception is known to be associated with poor outcomes. Among men and women, clinical outcomes after heart valve surgery are known to differ, but knowledge about differences in illness perception is sparse. OBJECTIVES: The aim of this study is to describe the differences in illness perception among men and women after open heart valve surgery and to identify sociodemographic and clinical characteristics associated with worse illness perception in men and women. METHODS: In a national cross-sectional study combined with register-based clinical and sociodemographic information, data on illness perception were collected with the Brief Illness Perception Questionnaire.Worse illness perception was defined as the worst quartile of each item of the Brief Illness Perception Questionnaire. Multiple logistic regression analyses were conducted to explore characteristics associated with worse illness perception. RESULTS: Of 1084 eligible patients, 32% (n = 349) completed the questionnaire (67% men; mean age, 68 years). Compared with men, women reported significantly worse scores of illness perception in 6 of 8 items. Furthermore, being female, age, length of stay, and comorbidity were associated with worse illness perception (worse quartile of scores). Age, higher educational level, and comorbidity were found to be associated with worse illness perception for men and length of stay for women. CONCLUSION: After open heart valve surgery, illness perception differs among men and women, with women having worse illness perception. Among the total population, being female, age, a longer length of stay, and comorbidity were also associated with worse illness perception.

Psychometric properties of the Danish Hospital Anxiety and Depression Scale in patients with cardiac disease: results from the DenHeart survey.

BACKGROUND: Anxiety and depression symptoms are common among cardiac patients. The Hospital Anxiety and Depression Scale (HADS) is frequently used to measure symptoms of anxiety and depression; however, no study on the validity and reliability of the scale in Danish cardiac patients has been done. The aim, therefore, was to evaluate the psychometric properties of HADS in a large sample of Danish patients with the four most common cardiac diagnoses: ischemic heart disease, arrhythmias, heart failure and heart valve disease. METHODS: The DenHeart study was designed as a national cross-sectional survey including the HADS, SF-12 and HeartQoL and combined with data from national registers. Psychometric evaluation included analyses of floor and ceiling effects, structural validity using both exploratory and confirmatory factor analysis and hypotheses testing of convergent and divergent validity by relating the HADS scores to the SF-12 and HeartQoL. Internal consistency reliability was evaluated by Cronbach's alpha, and differential item functioning by gender was examined using ordinal logistic regression. RESULTS: A total of 12,806 patients (response rate 51%) answered the HADS. Exploratory factor analysis supported the original two-factor structure of the HADS, while confirmatory factor analysis supported a three-factor structure consisting of the original depression subscale and two anxiety subscales as suggested in a previous study. There were floor effects on all items and ceiling effect on item 8. The hypotheses regarding convergent validity were confirmed but those regarding divergent validity for HADS-D were not. Internal consistency was good with a Cronbach's alpha of 0.87 for HADS-A and 0.82 for HADS-D. There were no indications of noticeable differential item functioning by gender for any items. CONCLUSIONS: The present study supported the evidence of convergent validity and high internal consistency for both HADS outcomes in a large sample of Danish patients with cardiac disease. There are, however, conflicting results regarding the factor structure of the scale consistent with previous research. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01926145.

The association between self-reported health status and adverse events: a comparison among coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI).

PURPOSE: While several studies have investigated clinical outcomes following coronary artery bypass grafting (CABG) vs. percutaneous coronary intervention (PCI), studies investigating self-reported health and the association with adverse outcomes are limited. Thus, the aim was to investigate differences in health-related quality of life (HRQoL), anxiety and depression at discharge and the association with a composite endpoint of the first event of acute cardiac readmission, revascularisation or 1-year mortality among patients undergoing CABG vs. PCI. METHODS: Data from the national cohort study, DenHeart, were used, including measures of HRQoL; EuroQoL-5D-5L (EQ-5D Index Score and VAS) and HeartQoL (Global, Physical and Emotional), anxiety and depression (Hospital Anxiety and Depression Scale, HADS) and register-based follow-up. A total of 7000 patients were included (CABG n = 652, PCI n = 6348) (median age 65, 75% men). Cox Proportional Hazard models were performed among a propensity-matched population of responders (n = 520). RESULTS: HRQoL was significantly better among patients undergoing PCI vs. CABG, but with no differences in time to readmission or revascularisation. HRQoL, anxiety and depression were significantly associated with the risk of the composite endpoint among the PCI group (Hazard Ratio, HR (95% confidence intervals, CI) [EQ-5D index score 3.07 (1.67-5.67), EQ-5D VAS 0.97 (0.96-0.99), HeartQol Global 0.61 (0.38-0.95), HeartQol Emotional 0.56 (0.39-0.80), HADS-D ≥ 8 3.12 (1.61-6.01), HADS-A ≥ 8 2.08 (1.14-3.80)]. CONCLUSION: Patients undergoing PCI reported better HRQoL at discharge compared with patients undergoing CABG, whereas readmission rates were similar. Self-reported health was associated with the risk of adverse events among patients undergoing PCI, but not among patients undergoing CABG. CLINICAL TRIAL REGISTRATION: NCT01926145.

Cardiac Rehabilitation for Patients Treated for Atrial Fibrillation With Ablation Has Long-Term Effects: 12-and 24-Month Follow-up Results From the Randomized CopenHeartRFA Trial.

OBJECTIVE: To assess outcomes at 12 and 24 months after participation in a multidisciplinary cardiac rehabilitation program plus usual care compared with usual care alone for patients treated for atrial fibrillation with catheter ablation. DESIGN: Long-term follow-up on the randomized CopenHeartRFA trial. SETTING: Patients were enrolled and outcome assessed at the hospital and the intervention were carried out at the hospital or at local rehabilitation centers. PARTICIPANTS: Patients (N=210) treated for atrial fibrillation with catheter ablation included in the CopenHeartRFA trial. INTERVENTIONS: A 6-month cardiac rehabilitation program consisting of physical exercise and psychoeducational consultations plus usual care or usual care alone. MAIN OUTCOME MEASURES: Physical capacity was measured by peak oxygen uptake (Vo2peak) at 12 months, and patient-reported outcomes on perceived health, anxiety, and depression were collected by validated questionnaires at 12 and 24 months. Information on hospital admissions and mortality was collected through national registers up to 24 months. RESULTS: Mean Vo2peak was higher at 12 months in the cardiac rehabilitation group (cardiac rehabilitation group: 25.82 mL/kg/min vs usual care group, 22.43 mL/kg/min, P=.003). A lower proportion of patients had high levels of anxiety at 24 months in the cardiac rehabilitation group compared to usual care (12% vs 24%, P=.004). There was no difference in mortality or hospital admissions at 24 months between groups. CONCLUSIONS: This long-term follow-up of a comprehensive multidisciplinary cardiac rehabilitation program for patients treated for atrial fibrillation with catheter ablation found sustained improvements with respect to physical capacity and anxiety compared to usual care but no difference on mortality or hospital admission.

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.

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.

Validity, reliability and responsiveness of the Body Image Quality of Life Inventory in patients treated for infective endocarditis.

RATIONALE AND OBJECTIVES: Suffering through infective endocarditis (IE) can drastically alter a person's physical appearance, and body image-related concerns have been reported by patients. The extent and severity of the phenomenon has not previously been explored, as no quantitative measure has been validated in this patient population. The purpose of this study was thus to assess the validity, reliability and responsiveness of the Danish Body Image Quality of Life Inventory (BIQLI-DA) on patients treated for IE. METHODS: We evaluated the psychometric properties of the BIQLI-DA on data obtained in the CopenHeart IE trial, which is a randomised clinical trial evaluating the effects of comprehensive cardiac rehabilitation for patients treated for IE. We administered the BIQLI-DA as part of data collection at baseline and 6 months. We examined the psychometric properties through correlations to other measures, including body mass index, Medical Outcome Short Form 36 and Hospital Anxiety and Depression Scale. In addition, we examined internal consistency on item and scale level and performed anova group-by-time interaction to test for responsiveness. RESULTS AND STUDY LIMITATION: Participants were seventy patients with a mean age of 58 years and of which 83% were men. Results indicated convergent construct validity by confirming hypothesised associations to potentially related constructs. The BIQLI-DA was found to be highly internally consistent with a Cronbach's alpha of 0.96. Instrument responsiveness was indicated by a significant group-by-time interaction. Support for the validity of the BIQLI-DA might have been strengthened by a larger sample with more women. A more optimal design for testing responsiveness would possibly have allowed for clearer conclusions. CONCLUSIONS: The BIQLI-DA may be applicable in healthcare research as it seems to be valid, reliable and responsive; however, evidence should be strengthened through further exploration of instrument performance, particularly regarding responsiveness.

Instrument translation and initial psychometric evaluation of the Danish Body Image Quality of Life Inventory.

RATIONALE AND OBJECTIVES: Negative body perception has been reported in a number of patient populations. No instrument in Danish for measuring body image-related concerns has been available. Without such an instrument, understanding of the phenomenon in Danish-speaking populations is limited. The purpose of the study was thus to translate and validate a Danish version of the Body Image Quality of Life Inventory (BIQLI), in order to obtain a valid instrument applicable for healthcare research. METHODS: The study consisted of two phases: (i) instrument adaptation, including forward and back translation, expert committee comparisons and cognitive interviewing, and (ii) empirical testing of the Danish version (BIQLI-DA) with subsequent psychometric evaluation. Hypothesised correlations to other measures, including body mass index (BMI), Medical Outcome Short Form-8 (SF-8), Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 and Symptom Check List-90-Revised (SCL-90-R® ) were tested. In addition, exploratory factor structure analysis (EFA) and internal consistency on item and scale level were performed. RESULTS AND STUDY LIMITATIONS: The adapted instrument was found to be semantically sound, yet concerns about face validity did arise through cognitive interviews. Danish college students (n = 189, 65 men, Mage = 21.1 years) participated in the piloting of the BIQLI-DA. Convergent construct validity was demonstrated through associations to related constructs. Exploratory factor analysis revealed a potential subscale structure. Finally, results showed a high internal consistency (Cronbach's alpha = 0.92). Support for the validity of the BIQLI-DA might have been strengthened by repeating cognitive interviews after layout alterations, by piloting the instrument on a larger sample. CONCLUSIONS: This study demonstrated tentative support for the validity of the Danish Body Image Quality of Life (BIQLI-DA) and found the measure to be reliable in terms of internal consistency. Further exploration of response processes and construct validity is needed.

Insufficient living: experiences of recovery after infective endocarditis.

BACKGROUND: Infective endocarditis (IE) is a traumatic health event, and recovery is often associated with massive physical deconditioning and reduced quality of life. Patients also report reduced cognitive functioning and are at risk of developing anxiety and depression as well as posttraumatic stress disorder. Although studies have found that survivors of IE have impaired physical functioning and mental health, little is known about patient experiences contributing to these findings. OBJECTIVE: The aim of this study was to describe patient experiences of recovery after IE. SUBJECTS AND METHODS: Within a phenomenological-hermeneutical framework, a qualitative interview study was conducted that included 6 men and 5 women (aged 29-86 years). Patients were interviewed 3 to 6 months after discharge. Analysis consisted of 3 levels: naive reading, structured analysis, and critical interpretation and discussion. FINDINGS: The overall concept that emerged was "Insufficient Living." Patients all experienced a life after illness, which was perceived as insufficient. The overall concept can be interpreted in terms of the following 3 themes. The first was "an altered life," where participants described a phase of adaptation to a new life situation, which some perceived as manageable and temporary, whereas others found extremely distressing and prolonged. "Shocking weakness" was experienced physically, cognitively, and emotionally, and although it subsided quickly for a few, most experienced a persisting weakness and felt frustrated about the prolonged recovery phase. In "the road to recovery," support from relatives and healthcare professionals, as well as one's own actions, was emphasized as important in facilitating recovery. CONCLUSIONS: Recovery after IE is perceived as "Insufficient Living." Patients experience an altered life and shocking weakness, and on the road to recovery, support is needed. Research in follow-up care, supporting patients' ability to cope with potential physical and psycho-emotional consequences of IE, is encouraged as a result of these findings.
