Background: Shared decision making (SDM) between healthcare professionals and persons with CVD can have a positive impact on motivation, adherence, or sustainability regarding long-term goals and integration of cardiovascular disease (CVD) rehabilitation in the everyday lives of persons with CVD. SDM can foster the transition between regular heart-healthy activity at rehabilitation facilities and more independent activity at home, but it is often challenging to implement SDM given limited time and resources, e.g., in the daily practice of rehabilitation. Digital tools can help but must be appropriately tailored for situated use and user needs. Objective: We aimed to (1) describe in how far SDM is manifested in the situated context when using a digital tool developed by our group, and, based on that, (2) reflect on how digital health tools can be designed to facilitate and improve the SDM process. Methods: In the context of a field study, we investigated how SDM is already naturally applied and manifested when using a digital tool for joint physical activity planning in cardiac rehabilitation in clinical practice. In a two-week qualitative study, we collected data on expectations, experiences and interactions during the use of a digital health tool by seven persons with CVD and five healthcare professionals. Data was collected by means of observations, interviews, questionnaires and a self-reported diary, and analysed with a particular focus on episodes related to SDM. Results: We found that SDM was manifested in the situated context to limited extent. For example, we identified high improvement potential for more structured goalsetting and more explicit consideration of preferences and routines. Based on mapping our findings to temporal phases where SDM can be adopted, we highlight implications for design to further support SDM in clinical practice. We consider this as “SDM supportive design in digital health apps,” suggesting for example step-by-step guidance to be used during the actual consultation. Conclusion: This study contributes to further understanding and integration of SDM in digital health tools with a focus on rehabilitation, to empower and support both persons with CVD and healthcare professionals.

In Austria, exercise therapy is an accredited profession that requires academic training on a university’s master level. However, exercise therapy is not listed in the service plans of health and medical insurance funds and is therefore not reimbursed as a health service for patients. This position paper aims to compile the scientific evidence of the efficacy and effectiveness of exercise therapy as a treatment component in medical care. It also informs about the skills and competencies that exercise therapists acquire during their university education in sport science. Based on that, the necessity to include exercise therapy as a health service for patients is argued. Additionally, legal parity for exercise therapists within the healthcare professions offering evidence-based treatment methods is advocated. Numerous studies confirm that exercise therapy clearly leads to improvements in musculoskeletal, internal, neurological, psychiatric, and psychosomatic diseases. Exercise therapy is thus a highly evidence-based, low-sideeffect component of prevention, treatment, and rehabilitation measures for almost all chronic diseases. It has a positive impact on pathogenesis, symptoms, fitness, quality of life, morbidity, and mortality of patients. The five-year academic training in sport science for exercise therapists conveys medical, theoretical knowledge, and practical skills on training and exercise, communication-related, sports-, and movement-related skills, as well as a profound education in scientific methodology. Consequently, the integration of exercise as therapeutic treatment into the healthcare system is highly indicated from a medical, societal and economic perspective. A new legal framework offering self-employment regulations for exercise therapists is required. [ABSTRACT FROM AUTHOR]

Objective: To determine if supervised training, after the completion of cardiac rehabilitation program, performed for a further two years would help maintain beneficial effects achieved during prolonged outpatient cardiac rehabilitation. Design: Longitudinal parallel-grouped intervention study. Subjects: Patients with coronary artery disease (n = 41, age 59.5 ± 9.3 years), who finished cardiac rehabilitation phase III in our outpatient cardiac rehabilitation facility. Intervention: Two years of supervised exercise training consisting of endurance (either high intensity interval training or pyramid training) and resistance training sessions once a week. Main measurement: Peak physical work capacity was assessed via an ergometry testing at the beginning and at the end of the study. Results: Comparisons between end-of-cardiac rehabilitation and two years post cardiac rehabilitation revealed maintenance of peak physical work capacity after two years (begin vs end: 170 ± 59 W vs 167 ± 60 W; −0.5 ± 12.8%; p = 0.521). This was independent of exercise training protocols (percent change begin vs end: pyramid: 1.5 ± 11.8%; interval: −1.6 ± 13.4%; p = 0.459). Conclusion: Improvement of physical exercise capacity gained during outpatient cardiac rehabilitation can be maintained for up to two years by once-weekly supervised exercise training. Long-term, group-based exercise programs offered at the end of cardiac rehabilitation might be an effective tool to help patients maintain their physical work capacity. [ABSTRACT FROM AUTHOR]

Functional impairment caused by chronic obstructive pulmonary disease (COPD) impacts on activities of daily living and quality of life. Indeed, patients' submaximal exercise capacity is of crucial importance. It was the aim of this study to investigate the effects of an exercise training intervention with and without supplemental oxygen on submaximal exercise performance. This is a secondary analysis of a randomized, controlled, double‐blind, crossover trial. 29 COPD patients (63.5 ± 5.9 years; FEV1 46.4 ± 8.6%) completed two consecutive 6‐week periods of high‐intensity interval cycling and strength training, which was performed three times/week with either supplemental oxygen or medical air (10 L/min). Submaximal exercise capacity as well as the cardiocirculatory, ventilatory, and metabolic response were evaluated at isotime (point of termination in the shortest cardiopulmonary exercise test), at physical work capacity at 110 bpm of heart rate (PWC 110), at the anaerobic threshold (AT), and at the lactate‐2 mmol/L threshold. After 12 weeks of exercise training, patients improved in exercise tolerance, shown by decreased cardiocirculatory (heart rate, blood pressure) and metabolic (respiratory exchange ratio, lactate) effort at isotime; ventilatory response was not affected. Submaximal exercise capacity was improved at PWC 110, AT and the lactate‐2 mmol/L threshold, respectively. Although supplemental oxygen seems to affect patients' work rate at AT and the lactate‐2 mmol/L threshold, no other significant effects were found. The improved submaximal exercise capacity and tolerance might counteract patients' functional impairment. Although cardiovascular and metabolic training adaptations were shown, ventilatory efficiency remained essentially unchanged. The impact of supplemental oxygen seems less important on submaximal training effects. [ABSTRACT FROM AUTHOR]

Hypoxia challenges left ventricular (LV) function due to reduced energy supply. Conflicting results exist whether high‐altitude exposure impairs LV diastolic function and thus contributes to the high altitude‐induced increase in systolic pulmonary artery pressure (sPAP) and reduction in stroke volume (SV). This study aimed to assess LV diastolic function, LV end‐diastolic pressure (LVEDP), and LA mechanics using comprehensive echocardiographic imaging in healthy volunteers at 4559 m. Fifty subjects performed rapid (<20 hours) and active ascent from 1130 m to 4559 m (high). All participants underwent echocardiography during baseline examination at 424 m (low) as well as 7, 20 and 44 hours after arrival at high altitude. Heart rate (HR), sPAP, and comprehensive volumetric‐ and Doppler‐ as well as speckle tracking‐derived LA strain parameters were obtained to assess LV diastolic function, LA mechanics, and LVEDP in a multiparametric approach. Data for final analyses were available in 46 subjects. HR (low: 64 ± 11 vs high: 79 ± 14 beats/min, P < 0.001) and sPAP (low: 24.4 ± 3.8 vs high: 38.5 ± 8.2 mm Hg, P < 0.001) increased following ascent and remained elevated at high altitude. Stroke volume (low: 64.5 ± 15.0 vs high: 58.1 ± 16.4 mL, P < 0.001) and EDV decreased following ascent and remained decreased at high altitude due to decreased LV passive filling volume, whereas LA mechanics were preserved. There was no case of LV diastolic dysfunction or increased LVEDP estimates. In summary, this study shows that rapid and active ascent of healthy individuals to 4559 m impairs passive filling and SV of the LV. These alterations were not related to changes in LV and LA mechanics. [ABSTRACT FROM AUTHOR]
