Living Lab Data of Patient Needs and Expectations for eHealth-Based Cardiac Rehabilitation in Germany and Spain From the TIMELY Study: Cross-Sectional Analysis.

BACKGROUND: The use of eHealth technology in cardiac rehabilitation (CR) is a promising approach to enhance patient outcomes since adherence to healthy lifestyles and risk factor management during phase III CR maintenance is often poorly supported. However, patients' needs and expectations have not been extensively analyzed to inform the design of such eHealth solutions. OBJECTIVE: The goal of this study was to provide a detailed patient perspective on the most important functionalities to include in an eHealth solution to assist them in phase III CR maintenance. METHODS: A guided survey as part of a Living Lab approach was conducted in Germany (n=49) and Spain (n=30) involving women (16/79, 20%) and men (63/79, 80%) with coronary artery disease (mean age 57 years, SD 9 years) participating in a structured center-based CR program. The survey covered patients' perceived importance of different CR components in general, current usage of technology/technical devices, and helpfulness of the potential features of eHealth in CR. Questionnaires were used to identify personality traits (psychological flexibility, optimism/pessimism, positive/negative affect), potentially predisposing patients to acceptance of an app/monitoring devices. RESULTS: All the patients in this study owned a smartphone, while 30%-40% used smartwatches and fitness trackers. Patients expressed the need for an eHealth platform that is user-friendly, personalized, and easily accessible, and 71% (56/79) of the patients believed that technology could help them to maintain health goals after CR. Among the offered components, support for regular physical exercise, including updated schedules and progress documentation, was rated the highest. In addition, patients rated the availability of information on diagnosis, current medication, test results, and risk scores as (very) useful. Of note, for each item, except smoking cessation, 35%-50% of the patients indicated a high need for support to achieve their long-term health goals, suggesting the need for individualized care. No major differences were detected between Spanish and German patients (all P>.05) and only younger age (P=.03) but not sex, education level, or personality traits (all P>.05) were associated with the acceptance of eHealth components. CONCLUSIONS: The patient perspectives collected in this study indicate high acceptance of personalized user-friendly eHealth platforms with remote monitoring to improve adherence to healthy lifestyles among patients with coronary artery disease during phase III CR maintenance. The identified patient needs comprise support in physical exercise, including regular updates on personalized training recommendations. Availability of diagnoses, laboratory results, and medications, as part of a mobile electronic health record were also rated as very useful.

A framework for the automatic description of healthcare processes in natural language: Application in an aortic stenosis integrated care process.

In this paper, we propose a framework for the automatic generation of natural language descriptions of healthcare processes using quantitative and qualitative data and medical expert knowledge. Inspired by the demand of novel ways of conveying process mining analysis results of healthcare processes (Rojas et al., 2016), our framework is based on the most widely used Data-To-Text (D2T) pipeline (Reiter, 2007) and on the usage of process mining techniques. Backed by a general model that handles process data, this framework is able to quantify attributes in time during a process life-span, recall temporal relations and waiting times between events and its possible causes and compare case (patient) attributes between groups, among other features. Through integrating fuzzy quantification techniques, our framework is able to represent relevant quantitative process information with some degree of uncertainty present on it and describe it in natural language involving uncertain terms. A real application over the Aortic Stenosis Integrated Care Process of the University Hospital of Santiago de Compostela is presented, showcasing the potential of our framework for providing natural language descriptions of healthcare processes addressed to medical experts. Following the standards of D2T systems, manual human validation was conducted for the generated natural language descriptions by fifteen medical experts in Cardiology. Validation results are very positive, since a global average of 4.07/5.00 was achieved for questions related to understandability, usefulness and impact of the natural language descriptions on the medical experts work. More precisely, results indicate i) that the modality which conveyed the information most efficiently was natural language ii) a very clear preference of texts over the usual graphic representation of process information as the way for conveying information to experts (4.28/5.00), and iii) natural language descriptions provide relevant and useful information about the process, allowing for its improvement.

Thirty-second sit-to-stand test as an alternative for estimating peak oxygen uptake and 6-min walking distance in women with breast cancer: a cross-sectional study.

PURPOSE: To determine whether the 30-s sit-to-stand (30STS) test can be a valid tool for estimating and stratifying peak oxygen uptake (VO2peak) and 6-min walking distance (6MWD) in women with breast cancer. METHODS: This cross-sectional study uses data from the ONCORE randomized controlled trial, including 120 women aged 18-70 years with early-stage breast cancer under treatment with anthracycline and/or anti-HER2 antibodies. Participant characteristics were collected at baseline and pooled data from functional assessment (30STS test, relative and absolute VO2peak, and 6MWD) were collected at baseline and post-intervention (comprehensive cardio-oncology rehabilitation program vs. usual care). Bivariate correlations and multivariate linear regression analyses were performed to study the relationship between functional test variables. RESULTS: The number of repetitions in the 30STS test showed (i) a moderate correlation with relative VO2peak (ml/kg/min) (r = 0.419; p < 0.001; n = 126), (ii) a weak correlation with absolute VO2peak (ml/min) (r = 0.241; p = 0.008; n = 120), and (iii) a moderate correlation with the 6MWD (r = 0.440; p < 0.001; n = 85). The ONCORE equations obtained from the multivariate regression models allowed the estimation of VO2peak and 6MWD (r2 = 0.390; r2 = 0.261, respectively) based on the 30STS test, and its stratification into tertiles (low, moderate, and high). CONCLUSION: The 30STS test was found to be a useful tool to estimate VO2peak and/or 6MWD in women with early-stage breast cancer. Its use may facilitate the assessment and stratification of functional capacity in this population for the implementation of therapeutic exercise programs if cardiopulmonary exercise testing (CPET) or 6MWT are not available.

Analysis of the implementation of an innovative IT solution to improve waiting times, communication with primary care and efficiency in Rheumatology.

OBJECTIVE: To describe in detail an innovative program based on telemedicine for semi-automated prioritization of referrals from Primary Care (PC) to Rheumatology, for reproducibility purposes, and to present the results of the implementation study. METHODS: The context and situation were carefully analyzed, paying attention to all processes in place, referral numbers, waiting times, and number of complementary tests prior to discharge from Rheumatology. The composition of the team, aims, users, scope, and implementation phases were defined. Eight process indicators were established and measured before and 32 months after the program implementation. RESULTS: The program, which includes IT circuits, algorithms based on response to specific guideline-based checklists, e-consultation, and appointments based on priority, was fully implemented in our health area after a pilot study in two PC centers. After implementation, 6185 rheumatology referrals showed an e-consultation response delay of 8.95 days, and to first face-to-face visit (after e-consultation) of 12.6 (previous delay before program implementation was 83.1 days). Resolution by e-consultation reached 20% (1195 patients did not need seeing the rheumatologist to have the problem solved), and 1369 patients (32%) were discharged after the first visit. The overall resolution rate was 44.0% (2564 discharges/5830 e-consultations). From a random sample of 100 visits, only 10% of patients needed additional complementary tests to make a diagnosis and decision by Rheumatology (20.9% decrease from previous period). CONCLUSION: A careful analysis of the situation and processes, with implementation of simple IT circuits, allows for the improvement of the efficiency and resolution of problems in Rheumatology.

Development of knowledge-based clinical decision support system for patients included in colorectal screening program.

BACKGROUND & AIMS: Colorectal (CRC) screening programs represent a large volume of procedures that need a follow-up endoscopy. A knowledge-based clinical decision support system (K-CDSS) is a technology which contains clinical rules and associations of compiled data that assist with clinical decision-making tasks. We develop a K-CDSS for management of patients included in CRC screening and surveillance of colorectal polyps. METHODS: We collected information on 48 variables from hospital colonoscopy records. Using DILEMMA Solutions Platform © (https://www.dilemasolution.com) we designed a prototype K-CDSS (PoliCare CDSS), to provide tailored recommendations by combining patients data and current guidelines recommendations. The accuracy of rules was verified using four scenarios (normal colonoscopy, lesions different than polyps, non-advanced adenomas and advanced adenomas). We studied the degree of agreement between the clinical assessments made by expert doctors and nurses equipped with PoliCare CDSS. Two experts confirmed a correlation between guidelines and PoliCare recommendations. RESULTS: 56 consecutive endoscopy cases from colorectal screening program were included (62.8 years; range 53-71). Colonoscopy results were: absence of colon lesions (n=7, 12.5%), lesions in the colon that are not polyps (n=3, 5.4%) and resected colonic polyps (n=46, 82.1%; 100% R0 resection). Patients with resected polyps presented non-advanced adenoma (n=21, 45.6%) or advanced lesions (n=25, 54.4%). There were no differences in erroneous orders with PoliCare CDSS (Kappa value 1.0). CONCLUSIONS: PoliCare CDSS can easily be integrated into the workflow for improving the overall efficiency and better adherence to evidence-based guidelines.

A randomized trial to evaluate the impact of exercise-based cardiac rehabilitation for the prevention of chemotherapy-induced cardiotoxicity in patients with breast cancer: ONCORE study protocol.

BACKGROUND: Anthracyclines and monoclonal antibodies against human epidermal growth factor receptor-2 (HER2) are frequently used to treat breast cancer but they are associated with risk of developing cardiotoxicity. Implementation of cardioprotective strategies as part of breast cancer treatment are needed. To date, a limited number of studies have examined the effectiveness of cardiac rehabilitation programs or exercise programs in the prevention of cardiotoxicity through an integral assessment of cardiac function. The ONCORE study proposes an exercise-based cardiac rehabilitation program as a non-pharmacological tool for the management of chemotherapy-induced cardiotoxicity. METHODS: The study protocol describes a prospective, randomized controlled trial aimed to determine whether an intervention through an exercise-based CR program can effectively prevent cardiotoxicity induced by anthracyclines and/or anti-HER2 antibodies in women with breast cancer. Three hundred and forty women with breast cancer at early stages scheduled to receive cardiotoxic chemotherapy will be randomly assigned (1:1) to participation in an exercise-based CR program (intervention group) or to usual care and physical activity recommendation (control group). Primary outcomes include changes in left ventricular ejection fraction and global longitudinal strain as markers of cardiac dysfunction assessed by transthoracic echocardiography. Secondary outcomes comprise levels of cardiovascular biomarkers and cardiopulmonary function through peak oxygen uptake determination, physical performance and psychosocial status. Supervised exercise program-related outcomes including safety, adherence/compliance, expectations and physical exercise in- and out-of-hospital are studied as exploratory outcomes. Transthoracic echocardiography, clinical test and questionnaires will be performed at the beginning and two weeks after completion of chemotherapy. DISCUSSION: The growing incidence of breast cancer and the risk of cardiotoxicity derived from cancer treatments demand adjuvant cardioprotective strategies. The proposed study may determine if an exercise-based CR program is effective in minimizing chemotherapy-induced cardiotoxicity in this population of women with early-stage breast cancer. The proposed research question is concrete, with relevant clinical implications, transferable to clinical practice and achievable with low risk.

Clinical outcomes after cardiac rehabilitation in elderly patients with and without diabetes mellitus: The EU-CaRE multicenter cohort study.

BACKGROUND: The prevalence of patients with concomitant cardiovascular disease and diabetes mellitus (DM) is increasing rapidly. We aimed to compare the effectiveness of current cardiac rehabilitation (CR) programs across seven European countries between elderly cardiac patients with and without DM. METHODS: 1633 acute and chronic coronary artery disease (CAD) patients and patients after valve intervention with an age 65 or above who participated in comprehensive CR (3 weeks to 3 months, depending on centre) were included. Peak oxygen uptake (VO2 peak), body mass index, resting systolic blood pressure, low-density lipoprotein-cholesterol (LDL-C), and glycated haemoglobin (HbA1c) were assessed before start of CR, at termination of CR (variable time point), and 12 months after start of CR, with no intervention after CR. Baseline values and changes from baseline to 12-month follow-up were compared between patients with and without DM using mixed models, and mortality and hospitalisation rates using logistic regression. RESULTS: 430 (26.3%) patients had DM. Patients with DM had more body fat, lower educational level, more comorbidities, cardiovascular risk factors, and more advanced CAD. Both groups increased their VO2 peak over the study period but with a significantly lower improvement from baseline to follow-up in patients with DM. In the DM group, change in HbA1c was associated with weight change but not with change in absolute VO2 peak. 12-month cardiac mortality was higher in patients with DM. CONCLUSIONS: While immediate improvements in VO2 peak after CR in elderly patients with and without DM were similar, 12-month maintenance of this improvement was inferior in patients with DM, possibly related to disease progression. Glycemic control was less favourable in diabetic patients needing insulin in the short- and long-term. Since glycemic control was only related to weight loss but not to increase in exercise capacity, this highlights the importance of weight loss in obese DM patients during CR.

Relevance of Dementia in Atrial Fibrillation Patients within a Specific European Health Care Area.

INTRODUCTION: Atrial fibrillation might increase the risk of dementia. We aim to test the hypothesis that dementia could reclassify the actual risk of stroke and death predicted by the CHA2DS2-VASc in patients with atrial fibrillation (AF). METHODS: A prospective study performed in a specific health care area. RESULTS: From our health care area (n = 348,985), throughout 2013, AF was codified in 7,990 (2.08%). Mean age was 76.83 ± 10.5, mean CHA2DS2-VASc = 3.5, 4,056 (50.8%) were females and 287 (3.6%) were diagnosed to have dementia. Patients with dementia were older and presented a higher rate of all the components of the CHA2DS2-VASc-expect vasculopathy. Differences in overall mortality were observed but not in stroke and haemorrhagic events. After propensity score matched analysis, dementia was independently associated with all-cause mortality. Addition of dementia to CHA2DS2-VASc reclassified 7.7 and 16.6% of the cohort with regard to thromboembolic events and death risk respectively. CONCLUSIONS: Patients with dementia presented a more adverse risk profile, with significant differences in all-cause mortality.

Very brief training for laypeople in hands-only cardiopulmonary resuscitation. Effect of real-time feedback.

BACKGROUND: Bystander cardiopulmonary resuscitation (CPR) improves survival from out-of-hospital cardiac arrest, but rates and performance quality remain low. Although training laypeople is a primary educational goal, the optimal strategy is not well defined. This study aimed to determine whether a short training with real-time feedback was able to improve hands-only CPR among untrained citizens. METHODS: On the occasion of the 2015 World Heart Day and the European Restart a Heart Day, a pilot study involving 155 participants (81 laypeople, 74 health care professionals) was conducted. Participants were invited to briefly practice hands-only CPR on a manikin and were after evaluated during a 2-minute chest compression (CC) test. During training brief instructions regarding hand position, compression rate and depth according to the current guidelines were given and real-time feedback was provided by a Laerdal SkillReporting System. RESULTS: Mean CC rate was significantly higher among health care professionals than among laypeople (119.07 ± 12.85 vs 113.02 ± 13.90 min(-1); P = .006), although both met the 100-120 CC min(-1) criterion. Laypeople achieved noninferior results regarding % of CC at adequate rate (51.46% ± 35.32% vs health care staff (55.97% ± 36.36%; P = .43) and depth (49.88% ± 38.58% vs 50.46% ± 37.17%; P = .92), % of CC with full-chest recoil (92.77% ± 17.17% vs 0.91% ± 18.84; P = .52), and adequate hand position (96.94% ± 14.78% vs 99.74 ± 1.98%; P = .11). The overall quality performance was greater than 70%, noninferior for citizens (81.23% ± 20.10%) vs health care staff (85.95% ± 14.78%; P = .10). CONCLUSION: With a very brief training supported by hands-on instructor-led advice and visual feedback, naïve laypeople are able to perform good-quality CC-CPR. Simple instructions, feedback, and motivation were the key elements of this strategy, which could make feasible to train big numbers of citizens.

Evaluation of SAMe-TT2R2 risk score for predicting the quality of anticoagulation control in a real-world cohort of patients with non-valvular atrial fibrillation on vitamin-K antagonists.

AIMS: Clinicians need to get better at identifying patients who would have poor quality of anticoagulation control with vitamin-K antagonists (VKAs). We assessed the predictive ability of SAMe-TT2R2 score, recently conceived for the prior purpose, and examined its relationship with major bleeding, thromboembolic (TE) complications, and death. METHODS AND RESULTS: Retrospectively, 911 consecutive patients with non-valvular atrial fibrillation (NVAF) started on VKAs within 8 months were studied. The percentage of international normalized ratios in therapeutic range (PINRR) at different levels was used as a metric of anticoagulation quality. We also tested the SAMe-TT2R2 predictability for major bleeding, TE complications, and death throughout 10 ± 3 months. The PINRR decreased from 62% at zero point to 53% at ≥4 points of SAMe-TT2R2. 82.1% of patients who achieved PINRR ≥ 70% had 0 or 1 point of SAMe-TT2R2. SAMe-TT2R2 performed significantly better at PINRR 70% than at 65 and 60% (c-statistic = 0.60 vs. c-statistic = 0.56). The calibration of SAMe-TT2R2 was excellent (Hosmer-Lemeshow test P-values ≥ 0.6). SAMe-TT2R2 showed significant association with the composite outcome of major bleeding, TE complications, and death [n = 98; hazard ratio (HR) = 1.32; 95% confidence interval (CI) 1.08-1.60]; the c-statistic was 0.57 (95% CI: 0.51-0.62) and P = 0.03. As individual outcomes, SAMe-TT2R2 was significantly associated with death (n = 60; HR = 1.3; 95% CI: 1.03-1.69), but not with either major bleeding (n = 30; HR = 1.2; 95% CI: 0.85-1.76) or TE complications (n = 15; HR = 1.01; 95% CI: 0.58-1.77). CONCLUSION: Among NVAF patients, SAMe-TT2R2 could represent a useful clinical tool to identify patients who would have poor quality of anticoagulation control with VKAs. SAMe-TT2R2 successfully predicts the composite outcome of major bleeding, TE complications, and death.

Comparison between CHA2DS2-VASc and the new R2CHADS2 and ATRIA scores at predicting thromboembolic event in non-anticoagulated and anticoagulated patients with non-valvular atrial fibrillation.

BACKGROUND: Accurate risk stratification is considered the first and most important step in the management of patients with non-valvular atrial fibrillation (NVAF). We compared the performance of the widely used CHA2DS2-VASc and the recently developed R2CHADS2 and ATRIA scores, for predicting thromboembolic (TE) event in either non-anticoagulated or anticoagulated patients with NVAF. METHODS: The non-anticoagulated cohort was comprised of 154 patients, whereas 911 patients formed the cohort of patients on vitamin-K-antagonist. The scores were computed using the criteria mentioned in their developmental cohorts. Measures of performance for the risk scores were evaluated at predicting TE event. RESULTS: In the non-anticoagulated cohort, 9 TE events occurred during 11 ± 2.7 months. CHA2DS2-VASc showed significant association with TE occurrence: hazard ratio (HR) = 1.58 (95 % confidence interval [95 % IC] 1.01-2.46), but R2CHADS2 and ATRIA did not (HR = 1.23 (95 % CI 0.86-1.77) and 1.20 (95 % CI 0.93-1.56), respectively. In the anticoagulated cohort, after 10 ± 3 months of follow up, 18 TE events were developed. In that cohort, the three scores showed similar association with TE risk: HR = 1.49 (95 % CI 1.13-1.97), 1.41 (95 % CI 1.13-1.77) and 1.37 (95 % CI 1.12-1.66) for CHA2DS2-VASc, R2CHADS2 and ATRIA, respectively. In both cohorts, no TE event occurred in patients classified in the low risk category according to CHA2DS2-VASc or R2CHADS2. CONCLUSIONS: In this study of NVAF patients, CHA2DS2-VASc has better association with TE events than the new R2CHADS2 and ATRIA risk scores in the non-anticoagulated cohort. CHA2DS2-VASc and R2CHADS2 can identify patients at truly low risk regardless of the anticoagulation status.

Exercise-based cardio-oncology rehabilitation for cardiotoxicity prevention during breast cancer chemotherapy: The ONCORE randomized controlled trial.

BACKGROUND: Breast cancer (BC) treatment with anthracyclines and/or anti-human epidermal growth factor receptor-2 (HER2) antibodies is associated with an increased risk of cardiovascular disease complications, including cancer therapy-related cardiac dysfunction (CTRCD). While Cardio-Oncology Rehabilitation (CORe) programs including exercise have emerged to minimize these risks, its role in preventing CTRCD is unclear. OBJECTIVES: We investigated the effectiveness of an exercise-based CORe program in preventing CTRCD [left ventricular ejection fraction (LVEF) drop ≥10% to a value <53% or a decrease >15% in global longitudinal strain (GLS)]. Secondary outcomes examined changes in cardiac biomarkers, physical performance including peak oxygen consumption, psychometric and lifestyle outcomes. Safety, adherence, and patient satisfaction were also assessed. METHODS: This is a randomized controlled trial including 122 early-stage BC women receiving anthracyclines and/or anti-HER2 antibodies, randomized to CORe (n = 60) or usual care with exercise recommendation (n = 62). Comprehensive assessments were performed at baseline and after cardiotoxic treatment completion. The average duration of the intervention was 5.8 months. RESULTS: No cases of CTRCD were identified during the study. LVEF decreased in both groups, but was significantly attenuated in the CORe group [-1.5% (-2.9, -0.1); p = 0.006], with no changes detected in GLS or cardiac biomarkers. The CORe intervention led to significant body mass index (BMI) reduction (p = 0.037), especially in obese patients [3.1 kg/m2 (1.3, 4.8)]. Physical performance and quality-of-life remained stable, while physical activity level increased in both groups. No adverse events were detected. CONCLUSIONS: This study suggests that CORe programs are safe and may help attenuate LVEF decline in BC women receiving cardiotoxic therapy and reduce BMI in obese patients.

Health-related quality of life in elderly cardiac patients undergoing cardiac rehabilitation and the association with exercise capacity: The EU-CaRE study.

AIMS: The ability to be physically active is pivotal to the quality of life in elderly patients. This study aims to describe the association between exercise capacity and health-related quality of life (HRQoL), anxiety, and depression following an exercise-based cardiac rehabilitation (CR) program in elderly cardiac patients. METHODS: Patients aged ≥65 years with acute and chronic coronary syndrome or heart valve surgery were consecutively included from 8 CR centers in 7 European countries. Exercise capacity (VO2peak(ml/kg/min)) was assessed with a cardiopulmonary exercise test (97%) or a six-minute walk test. Outcome variables included HRQoL (SF-36 physical and mental component scores (PCS and MCS)), anxiety (GAD-7), and depression (PHQ-9). Mixed models were used to address the association between baseline and the development in VO2peak, and outcome variables stratified on sex, and adjusted for baseline values, age, and CR center. RESULTS: A total of 1,633 patients were included (T0), 1,523 (93%) completed end-of-CR assessment (T1), and 1,457 (89%) 1-year follow-up (T2). Women had higher % of predicted VO2peak, but poorer scores in HRQoL, anxiety and depression at all time-points. All scores improved in both sexes at follow-up. We found significant associations between VO2peak at baseline as well as development in VO2peak and all outcome variables at T1 and T2 in men (all p < 0.001). In women, VO2peak was only associated with PCS scores (p < 0.001). CONCLUSIONS: Improvements in exercise capacity was strongly associated with improvements in HRQoL and mental health, however with stronger associations in men. The results highlight the importance of physical fitness for HRQol and mental health. The findings from this study might be useful to better target individual CR programs.

This study explores the association between exercise capacity and the well-being of elderly cardiac patients participating in a cardiac rehabilitation program, focusing on health-related quality of life (HRQoL), anxiety, and depression. Key Findings:Women, despite having higher percentages of predicted exercise capacity, consistently reported poorer HRQoL, anxiety, and depression scores compared to men at all assessed time points.Improvements in exercise capacity were strongly associated with positive changes in HRQoL and mental health, with these associations being more pronounced in men.

Results of a focused cardiac ultrasound program conducted by neurologists within a stroke care network with cardiac imaging units.

INTRODUCTION AND OBJECTIVES: Recently, neurologists have begun to perform focused cardiac ultrasound for the detection of a cardiac source of embolism in stroke patients, requiring them to undergo a prior accredited training process. We designed a prospective study to analyze the incidence of heart disease detected by a focused cardiac ultrasound program within a stroke care network with cardiac imaging units and to identify the outcomes of detected structural heart disease at 1 year of follow-up. METHODS: We included patients admitted to a university hospital for ischemic stroke or a transient ischemic attack between 2017 and 2021 who were evaluated by focused cardiac ultrasound. We studied the presence of structural heart disease and cardioembolic sources. We analyzed cardiovascular events (CVE) during the first year of follow-up. RESULTS: Focused cardiac ultrasound was performed in 706 patients. Structural heart disease was detected in 52.1% and a cardioembolic source in 31.9%. Adverse CVE occurred in 5.49% of the patients in the first year of follow-up. The presence of de novo structural heart disease was independently associated with a higher probability of adverse CVE (HR, 1.72; 95%CI, 1.01- 2.91; P=.046). CONCLUSIONS: Focused cardiac ultrasound within a stroke care network with cardiac imaging units is an accessible technique with high diagnostic yield. Its use allows clinical and therapeutic actions in the prevention of stroke recurrences and other CVEs in this group of patients.

Evaluating the Performance of the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the ACC/AHA Guidelines (CRUSADE) bleeding score in a contemporary Spanish cohort of patients with non-ST-segment elevation acute myocardial infarction.

BACKGROUND: The Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the ACC/AHA Guidelines (CRUSADE) model provides a risk score that predicts the likelihood of major bleeding in patients hospitalized for non-ST-elevation acute myocardial infarction. The aim of the present work was to evaluate the performance of this model in a contemporary cohort of patients hospitalized for non-ST-elevation acute myocardial infarction in Spain. METHODS AND RESULTS: The study subjects were 782 consecutive patients admitted to our center between February 2004 and June 2009 with non-ST-elevation acute myocardial infarction. For each patient, we calculated the CRUSADE risk score and evaluated its discrimination and calibration by the C statistic and the Hosmer-Lemeshow goodness-of-fit test, respectively. The performance of the CRUSADE risk score was evaluated for the patient population as a whole and for groups of patients treated with or without >or=2 antithrombotic medications and who underwent cardiac catheterization or not. The median CRUSADE score was 30 points (range, 18 to 45). A total of 657 patients (84%) were treated with >or=2 antithrombotic, of whom 609 (92.7%) underwent cardiac catheterization. The overall incidence of major bleeding was 9.5%. This incidence increased with the risk category: very low, 1.5%; low, 4.3%; moderate, 7.8%; high, 11.8%; and very high, 28.9% (P<0.001). For the patients as a whole, for the groups treated with or without >or=2 antithrombotics, and for the subgroup treated with >or=2 antithrombotics who did or did not undergo cardiac catheterization, the CRUSADE score showed adequate calibration and excellent discriminatory capacity (Hosmer-Lemeshow P>0.3 and C values of 0.82, 0.80, 0.70, and 0.80, respectively). However, it showed little capacity to discriminate bleeding risk in patients treated with >or=2 antithrombotics who did not undergo cardiac catheterization (C=0.56). CONCLUSIONS: The CRUSADE risk score was generally validated and found to be useful in a Spanish cohort of patients treated with or without >or=2 antithrombotics and in those treated with or without >or=2 antithrombotics who underwent cardiac catheterization. More studies are needed to clarify the validity of the CRUSADE score in the subgroup treated with >or=2 antithrombotics who do not undergo cardiac catheterization.

Greater burden of risk factors and less effect of cardiac rehabilitation in elderly with low educational attainment: The Eu-CaRE study.

AIMS: Socioeconomic status is a strong predictor of cardiovascular health. The aim of this study was to describe the immediate and long-term effects of cardiac rehabilitation (CR) across socioeconomic strata in elderly cardiac patients in Europe. METHODS AND RESULTS: The observational EU-CaRE study is a prospective study with eight CR sites in seven European countries. Patients ≥65 years with coronary heart disease or heart valve surgery participating in CR were consecutively included. Data were obtained at baseline, end of CR and at one-year follow up. Educational level as a marker for socioeconomic status was divided into basic, intermediate and high. The primary endpoint was exercise capacity (peak oxygen consumption (VO2peak)). Secondary endpoints were cardiovascular risk factors, medical treatment and scores for depression, anxiety and quality of life (QoL). A total of 1626 patients were included; 28% had basic, 48% intermediate and 24% high education. A total of 1515 and 1448 patients were available for follow-up analyses at end of CR and one-year, respectively. Patients with basic education were older and more often female. At baseline we found a socioeconomic gradient in VO2peak, lifestyle-related cardiovascular risk factors, anxiety, depression and QoL. The socioeconomic gap in VO2peak increased following CR (p for interaction <0.001). The socioeconomic gap in secondary outcomes was unaffected by CR. The use of evidence-based medication was good in all socioeconomic groups. CONCLUSIONS: We found a strong socioeconomic gradient in VO2peak and cardiovascular risk factors that was unaffected or worsened after CR. To address inequity in cardiovascular health, the individual adaption of CR according to socioeconomic needs should be considered.

Offering, participation and adherence to cardiac rehabilitation programmes in the elderly: a European comparison based on the EU-CaRE multicentre observational study.

AIMS: Cardiac rehabilitation (CR) is strongly recommended but participation of elderly patients has not been well characterized. This study aims to analyse current rates and determinants of CR referral, participation, adherence, and compliance in a contemporary European cohort of elderly patients. METHODS AND RESULTS: The EU-CaRE observational study included data from consecutive patients aged ≥ 65 with acute coronary syndrome, revascularization, stable coronary artery disease, or heart valve replacement, recruited in eight European centres. Rates and factors determining offering, participation, and adherence to CR programmes and compliance with training sessions were studied across centres, under consideration of extensive-outpatient vs. intensive-inpatient programmes. Three thousand, four hundred, and seventy-one patients were included in the offering and participation analysis. Cardiac rehabilitation was offered to 80.8% of eligible patients, formal contraindications being the main reason for not offering CR. Mean participation was 68.0%, with perceived lack of usefulness and transport issues being principal barriers. Mean adherence to CR programmes of participants in the EU-CaRE study (n = 1663) was 90.3%, with hospitalization/physical impairment as principal causes of dropout. Mean compliance with training sessions was 86.1%. Older age was related to lower offering and participation, and comorbidity was associated with lower offering, participation, adherence, and compliance. Intensive-inpatient programmes displayed higher adherence (97.1% vs. 85.9%, P < 0.001) and compliance (full compliance: 66.0% vs. 38.8%, P < 0.001) than extensive-outpatient programmes. CONCLUSION: In this European cohort of elderly patients, older age and comorbidity tackled patients' referral and uptake of CR programmes. Intensive-inpatient CR programmes showed higher completion than extensive-outpatient CR programmes, suggesting this formula could suit some elderly patients.

Effectiveness of Home-Based Mobile Guided Cardiac Rehabilitation as Alternative Strategy for Nonparticipation in Clinic-Based Cardiac Rehabilitation Among Elderly Patients in Europe: A Randomized Clinical Trial.

Importance: Although nonparticipation in cardiac rehabilitation is known to increase cardiovascular mortality and hospital readmissions, more than half of patients with coronary artery disease in Europe are not participating in cardiac rehabilitation. Objective: To assess whether a 6-month guided mobile cardiac rehabilitation (MCR) program is an effective therapy for elderly patients who decline participation in cardiac rehabilitation. Design, Setting, and Participants: Patients were enrolled in this parallel multicenter randomized clinical trial from November 11, 2015, to January 3, 2018, and follow-up was completed on January 17, 2019, in a secondary care system with 6 cardiac institutions across 5 European countries. Researchers assessing primary outcome were masked for group assignment. A total of 4236 patients were identified with a recent diagnosis of acute coronary syndrome, coronary revascularization, or surgical or percutaneous treatment for valvular disease, or documented coronary artery disease, of whom 996 declined to start cardiac rehabilitation. Subsequently, 179 patients who met the inclusion and exclusion criteria consented to participate in the European Study on Effectiveness and Sustainability of Current Cardiac Rehabilitation Programmes in the Elderly trial. Data were analyzed from January 21 to October 11, 2019. Interventions: Six months of home-based cardiac rehabilitation with telemonitoring and coaching based on motivational interviewing was used to stimulate patients to reach exercise goals. Control patients did not receive any form of cardiac rehabilitation throughout the study period. Main Outcomes and Measures: The primary outcome parameter was peak oxygen uptake (Vo2peak) after 6 months. Results: Among 179 patients randomized (145 male [81%]; median age, 72 [range, 65-87] years), 159 (89%) were eligible for primary end point analysis. Follow-up at 1 year was completed for 151 patients (84%). Peak oxygen uptake improved in the MCR group (n = 89) at 6 and 12 months (1.6 [95% CI, 0.9-2.4] mL/kg-1/min-1 and 1.2 [95% CI, 0.4-2.0] mL/kg-1/min-1, respectively), whereas there was no improvement in the control group (n = 90) (+0.2 [95% CI, -0.4 to 0.8] mL/kg-1/min-1 and +0.1 [95% CI, -0.5 to 0.7] mL/kg-1/min-1, respectively). Changes in Vo2peak were greater in the MCR vs control groups at 6 months (+1.2 [95% CI, 0.2 to 2.1] mL/kg-1/min-1) and 12 months (+0.9 [95% CI, 0.05 to 1.8] mL/kg-1/min-1). The incidence of adverse events was low and did not differ between the MCR and control groups. Conclusions and Relevance: These results suggest that a 6-month home-based MCR program for patients 65 years or older with coronary artery disease or a valvular intervention was safe and beneficial in improving Vo2peak when compared with no cardiac rehabilitation.

Changes and prognostic value of cardiopulmonary exercise testing parameters in elderly patients undergoing cardiac rehabilitation: The EU-CaRE observational study.

OBJECTIVE: We aimed 1) to test the applicability of the previously suggested prognostic value of CPET to elderly cardiac rehabilitation patients and 2) to explore the underlying mechanism of the greater improvement in exercise capacity (peak oxygen consumption, VO2) after CR in surgical compared to non-surgical cardiac patients. METHODS: Elderly patients (≥65 years) commencing CR after coronary artery bypass grafting, surgical valve replacement (surgery-group), percutaneous coronary intervention, percutaneous valve replacement or without revascularisation (non-surgery group) were included in the prospective multi-center EU-CaRE study. CPETs were performed at start of CR, end of CR and 1-year-follow-up. Logistic models and receiver operating characteristics were used to determine prognostic values of CPET parameters for major adverse cardiac events (MACE). Linear models were performed for change in peak VO2 (start to follow-up) and parameters accounting for the difference between surgery and non-surgery patients were sought. RESULTS: 1421 out of 1633 EU-CaRE patients performed a valid CPET at start of CR (age 73±5.4, 81% male). No CPET parameter further improved the receiver operation characteristics significantly beyond the model with only clinical parameters. The higher improvement in peak VO2 (25% vs. 7%) in the surgical group disappeared when adjusted for changes in peak tidal volume and haemoglobin. CONCLUSION: CPET did not improve the prediction of MACE in elderly CR patients. The higher improvement of exercise capacity in surgery patients was mainly driven by restoration of haemoglobin levels and improvement in respiratory function after sternotomy.

"Do GRACE (Global Registry of Acute Coronary events) risk scores still maintain their performance for predicting mortality in the era of contemporary management of acute coronary syndromes?".

BACKGROUND: Although the GRACE risk scores (RS) are the preferred scoring system for risk stratification in acute coronary syndromes (ACS), little is known whether these RS still maintain their performance in the current era. We aimed to investigate this issue in a contemporary population with ACS. METHODS: The study population composed of patients enrolled in the MASCARA national registry. The GRACE RS were calculated for each patient. Discrimination and calibration were evaluated with the C statistic and the Hosmer-Lemeshow test, in the whole population and according to the type of ACS, risk strata, and whether the patient had a history of diabetes and/or chronic renal failure. We determined if left ventricular ejection fraction (LVEF) provides incremental prognostic information above that established by the RS and whether percutaneous coronary intervention (PCI) during admission affects the performance of the score for predicting 6-month mortality. RESULTS: The 5,985 patients constituted the validation cohort for the in-hospital mortality RS and 5,635 the validation cohort for the 6-month mortality RS. Overall, both GRACE RS demonstrated excellent discrimination (C > 0.80) and calibration (all P values in Hosmer-Lemeshow >.1). Although similar results were seen in all subgroups, the 6-month mortality RS performed significantly less well in patients undergoing PCI compared to those patients who did not (C = 0.73 vs 0.76, P < .004). Adding LVEF to the RS did not convey significant prognostic information. CONCLUSIONS: The GRACE RS for predicting in-hospital and 6-month mortality still maintain their excellent performance in a contemporary cohort of patients with ACS. Further studies are needed to investigate the performance of the 6-month mortality GRACE score in patients undergoing in-hospital PCI. Left ventricular ejection fraction did not convey significant information over that provided by the RS.
