Current guidelines recommend individually adapted resistance training (RT) as a part of the exercise regime in patients with cardiovascular diseases. The aim of this review was to provide insights into current knowledge and understanding of how useful, feasible, safe, and effective RT is in patients with coronary artery disease (CAD), heart failure (HF), and valvular heart disease (VHD), with particular emphasis on the role of RT in elderly and/or frail patients.A review based on an intensive literature search: systematic reviews and meta-analyses published in 2010 or later; recent studies not integrated into meta-analyses or systematic reviews; additional manual searches.The results highlight the evaluation of effects and safety of RT in patients with CAD and HF with reduced ejection fraction (HFrEF) in numerous meta-analyses. In contrast, few studies have focused on RT in patients with HF with preserved ejection fraction (HFpEF) or VHD. Furthermore, few studies have addressed the feasibility and impact of RT in elderly cardiac patients, and data on the efficacy and safety of RT in frail elderly patients are limited. The review results underscore the high prevalence of age-related sarcopenia, disease-related skeletal muscle deconditioning, physical limitations, and frailty in older patients with cardiovascular diseases (CVD). They underline the need for individually tailored exercise concepts, including RT, aimed at improving functional status, mobility, physical performance and muscle strength in older patients. Furthermore, the importance of the use of assessment tools to diagnose frailty, mobility/functional capacity, and physical performance in the elderly admitted to cardiac rehabilitation is emphasized.

Myocarditis is an umbrella term for non-ischemic myocardial inflammation and remains a leading cause of sudden cardiac death in active individuals and athletes. Accurate diagnosing is challenging and diseases could often remain undetected. In the majority of cases, acute myocarditis resolves favourably. However, a relevant proportion of patients may have an increased risk of prognostically relevant cardiac arrhythmias and/or the development and progression of maladaptive myocardial remodelling (dilated cardiomyopathy). This review provides current knowledge on myocarditis and sports with special regard to the COVID-19 pandemic. Possible causes, common symptoms and proposed diagnostics are summarized. The relevance of temporary avoidance of intensive sports activities for both the prevention and therapy of acute myocarditis is discussed. Risk stratification, specific return-to-play recommendations and proposed follow-up diagnostics (also after COVID-19 infection) are presented.

Objectives To evaluate 20 days and 3 months follow-up effectiveness of cardiac rehabilitation (CR) enhanced by resistance/balance training and telephone-support program compared to usual CR care in improving quality of life, clinical course and physical activity behavior. Design Single-centre randomized controlled trial. Setting Inpatient CR clinic Subjects 116 (76.1 ± 6.7 years, 50% male) patients 14.5 ± 5.9 days after valve surgery/intervention were randomized to intervention group (IG, n = 60) or control group (CG, n = 56). Intervention Additional resistance/balance training (3 days/week) during phase-II CR and telephone-support program during 3-month follow-up. CG patients were provided with usual CR care. Main measures Short Form 36 Health Survey scales, European Quality of Life 5 Dimensions 3 Level Version QoL index, visual analog scale, clinical course, and physical activity behavior assessed with standardized questionnaires. Results IG reported statistically significant higher mental component score (48.5 ± 6.91 vs. 40.3 ± 11.21 at the baseline, 50.8 ± 9.76 vs. 42.6 ± 9.82 after 20 days, 49.4 ± 8.45 vs. 40.5 ± 8.9 after 12 weeks follow up), general health (48.6 ± 3.17 vs. 45.0 ± 2.95 at the baseline, 53.6 ± 3.02 vs. 43.8 ± 2.55 after 20 days, 53.2 ± 3.11 vs. 44.2 ± 3.07 after 12 weeks) and role limitations due to emotional problems (48.5 ± 15.2 vs. 27.7 ± 11.5 at the baseline, 72.7 ± 12.6 vs. 30.5 ± 11.2 after 20 days, 66.6 ± 14.2 vs. 36.1 ± 11.2 after 12 weeks) in all three assessments ( p Conclusions The addition of resistance/balance exercises and telephone-support program 12 weeks after to the CR could linked to higher physical activity levels and fewer clinical complications but did not lead to a significant improvement in quality of life.

Patients awaiting cardiac surgery seem to benefit from exercise-based-prehabilitation (EBPrehab) but the impact on different perioperative outcomes compared to standard care is still unclear.Eligible non-/randomized controlled studies investigating the impact of EBPrehab in adults scheduled for elective cardiac surgery were searched on 16th december 2020 from electronic databases, including MEDLINE, CENTRAL and CINAHL. The data were pooled and a meta-analysis was conducted.Out of 1.490 abstracts six studies (n = 665) were included into the review and meta-analysis. At post-intervention-interval and at post-surgery-interval, 6-minute-walking-distance (6MWD) improved significantly in EBPrehab-group compared to controls (mean difference (MD) = 75.4 m, 95% CI, 13.7-137.1 m; p = 0.02 and 30.5 m, 95% CI, 8.5-52.6 m; p = 0.007, respectively). Length of hospital stay (LOS) was significantly shorter in EBPrehab-group (MD = -1.00 day, 95% CI, -1.78 to -0.23; p = 0.01). Participation in EBPrehab revealed a significant decrease in the risk of postoperative atrial fibrillation (AF) in patients ≤65 years (risk ratio = 0.34, 95% CI, 0.14-0.83; p = 0.02).The participation in EBPrehab significantly improves post-intervention and post-surgery 6MWD, LOS and decreases the risk of postoperative AF in patients ≤65 years compared to controls.

©The European Society of Cardiology 2020. Article reuse guidelines : sagepub.com/journals-permissions, Secondary prevention through comprehensive cardiac rehabilitation has been recognized as the most cost-effective intervention to ensure favourable outcomes across a wide spectrum of cardiovascular disease, reducing cardiovascular mortality, morbidity and disability, and to increase quality of life. The delivery of a comprehensive and ‘modern’ cardiac rehabilitation programme is mandatory both in the residential and the out-patient setting to ensure expected outcomes. The present position paper aims to update the practical recommendations on the core components and goals of cardiac rehabilitation intervention in different cardiovascular conditions, in order to assist the whole cardiac rehabilitation staff in the design and development of the programmes, and to support healthcare providers, insurers, policy makers and patients in the recognition of the positive nature of cardiac rehabilitation. Starting from the previous position paper published in 2010, this updated document maintains a disease-oriented approach, presenting both well-established and more controversial aspects. Particularly for implementation of the exercise programme, advances in different training modalities were added and new challenging populations were considered. A general table applicable to all cardiovascular conditions and specific tables for each clinical condition have been created for routine practice.

Ambulante Herzgruppen sind ein wichtiger Teil der kardiovaskularen Langzeitpravention. Der eigentlich notwendigen Ausweitung des Angebotes ambulanter Herzgruppen steht der zunehmende arztliche Fachkraftemangel entgegen, da bisher alle Herzgruppen von Arzten begleitet werden mussen. Studiendaten zeigen, dass wahrend der letzten Jahrzehnte das Risiko von schwerwiegenden kardiovaskularen Ereignissen wahrend Bewegungstherapie gesunken ist. Dies ist v. a. auf die Fortschritte der kardiovaskularen Medizin im Hinblick auf Revaskularisationsstrategien und medikamentose Therapie zuruckzufuhren. Es erscheint somit nicht mehr notwendig, jede Herzgruppe von einem Arzt begleiten zu lassen, sondern es sollte eine Risikostratifikation erfolgen. In der „Standardherzgruppe“ ist keine arztliche Anwesenheit erforderlich. Die Gruppe wird von einem nichtarztlichen Herzgruppenleiter angeleitet, der uber eine entsprechende Qualifikation verfugt. Zudem muss ein automatischer externer Defibrillator (AED) vor Ort sein und die Moglichkeit eines sofortigen Notrufes an den Rettungsdienst gegeben sein. In der „Herzgruppe mit erhohtem Betreuungsbedarf“ wird hingegen eine arztliche Anwesenheit benotigt. In diese Gruppe werden Patienten eingeteilt, bei denen Risikokriterien, wie z. B. Angina pectoris oder Dyspnoe bei Belastung, erfullt sind. Ausgenommen von dieser Risikostratifikation sind Patienten, die die Aufnahmekriterien einer „Herzinsuffizienzherzgruppe“ erfullen. Diese neu seit Anfang 2020 eingefuhrte Hochrisikoherzgruppe wird durch speziell ausgebildete Herzgruppenleiter und Arzte angeleitet. Es wird kalkuliert, dass nach der vorgeschlagenen Regelung bei etwa 50 % aller Herzgruppenpatienten keine arztliche Gruppenbegleitung mehr benotigt wird. Durch dieses Modell konnten zukunftig noch mehr Patienten von ambulanten Herzgruppen profitieren, ohne dass ein Verlust an Sicherheit oder Effektivitat zu befurchten ware.

PURPOSE: Greater than 65% of all cardiac mortality is related to coronary artery disease (CAD). Cardiac rehabilitation (CR) aims to reduce cardiovascular risk and number of hospital readmissions. Cardiac maintenance programs (CMPs) are designed to sustain or improve health after completing early CR. Although CMPs are supported by most national health guidelines, few long-term studies on these diverse programs have been performed. METHODS: This was a retrospective repeated-measures analysis with case-controlled subanalysis. Within-subject differences for CMP participants were examined between enrollment and last clinical visit. Assessments included medical history, anthropometry, blood analysis, and cardiopulmonary exercise testing. A subset of 20 CMP participants were compared with 20 patients with CAD who chose not to participate in CMP, matched for age, sex, and follow-up duration. RESULTS: A total of 207 patients (60 ± 9 yr, 16% female) were included for the primary analyses. Average follow-up was 6.3 ± 4.8 yr (range 4-20 yr). CMP participants reduced peak workload (1.76 ± 0.56 to 1.60 ± 0.58 W/kg; P < .001) and aerobic capacity (26.1 ± 6.2 to 24.6 ± 7.1 mL/kg/min; P = .003). High-density lipoprotein-cholesterol increased significantly (48 ± 12 to 51 ± 14 mg/dL; P < .001), whereas all other metabolic risk factors remained unaffected. Matched controls had higher functional capacity (2.35 ± 0.81 vs 1.56 ± 0.52 W/kg; P < .001) and lower body mass index (25.3 ± 3.6 vs 28.6 ± 3.9 kg/m2) at baseline, but no significant differences with respect to long-term efficacy were observed. CONCLUSIONS: Long-term participation in CMP did not result in maintaining functional capacity or cardiovascular risk profile in patients with CAD. However, compared with matched nonparticipants, CMP participants (are more deconditioned at baseline) but do not seem to deteriorate as quickly.

Objective: To determine the impact of an exercise-based prehabilitation (EBPrehab) program on pre- and postoperative exercise capacity, functional capacity (FC) and quality of life (QoL) in patients awaiting elective coronary artery bypass graft surgery (CABG). Design: A two-group randomized controlled trail. Setting: Ambulatory prehabilitation. Subjects: Overall 230 preoperative elective CABG-surgery patients were randomly assigned to an intervention (IG, n = 88; n = 27 withdrew after randomization) or control group (CG, n = 115). Intervention: IG: two-week EBPrehab including supervised aerobic exercise. CG: usual care. Main measures: At baseline (T1), one day before surgery (T2), at the beginning (T3) and at the end of cardiac rehabilitation (T4) the following measurements were performed: cardiopulmonary exercise test, six-minute walk test (6MWT), Timed-Up-and-Go Test (TUG) and QoL (MacNew questionnaire). Results: A total of 171 patients (IG, n = 81; CG, n = 90) completed the study. During EBPrehab no complications occurred. Preoperatively FC (6MWTIG: 443.0 ± 80.1 m to 493.5 ± 75.5 m, P = 0.003; TUGIG: 6.9 ± 2.0 s to 6.1 ± 1.8 s, P = 0.018) and QoL (IG: 5.1 ± 0.9 to 5.4 ± 0.9, P IG: Δ-64.7 m, pT1–T3 = 0.013; Δ+47.2 m, pT1–T4 0.001; TUGIG: Δ+1.4 s, pT1–T3 = 0.003). Conclusions: A short-term EBPrehab is effective to improve perioperative FC and preoperative QoL in patients with stable coronary artery disease awaiting CABG-surgery.

Background: Although cardiovascular rehabilitation (CR) is well accepted in general, CR-attendance and delivery still considerably vary between the European countries. Moreover, clinical and prognostic effects of CR are not well established for a variety of cardiovascular diseases. Methods: The guidelines address all aspects of CR including indications, contents and delivery. By processing the guidelines, every step was externally supervised and moderated by independent members of the “Association of the Scientific Medical Societies in Germany” (AWMF). Four meta-analyses were performed to evaluate the prognostic effect of CR after acute coronary syndrome (ACS), after coronary bypass grafting (CABG), in patients with severe chronic systolic heart failure (HFrEF), and to define the effect of psychological interventions during CR. All other indications for CR-delivery were based on a predefined semi-structured literature search and recommendations were established by a formal consenting process including all medical societies involved in guideline generation. Results: Multidisciplinary CR is associated with a significant reduction in all-cause mortality in patients after ACS and after CABG, whereas HFrEF-patients (left ventricular ejection fraction

Background To evaluate the short- and mid-term effect of a specially tailored resistance and balance training provided in addition to usual cardiac rehabilitation (CR) care program in older patients after valve surgery/intervention. Methods Single-center (inpatient CR clinic in Lithuania) randomized controlled trial. Two hundred fifty-two patients were assessed for eligibility on the first day of admittance to CR early after (14.5 ± 5.9 days) valve surgery/intervention between January 2018 and November 2019. Participants were coded centrally in accordance with randomization 1:1 using a computerized list. Control group (CG) patients were provided with usual care phase-II-CR inpatient multidisciplinary CR program, while intervention group (IG) patients received additional resistance and balance training (3 d/wk). Patients participated in a 3-month follow-up. Main outcome measures were functional capacity (6 min walk test (6MWT, meters), cardiopulmonary exercise testing), physical performance (Short Physical Performance Battery (SPPB, score) and 5-m walk test (5MWT, meters/second)), strength (one repetition maximum test for leg press), physical frailty (SPPB, 5MWT). Results One hundred sixteen patients (76.1 ± 6.7 years, 50% male) who fulfilled the study inclusion criteria were randomized to IG (n = 60) or CG (n = 56) and participated in CR (18.6 ± 2.7 days). As a result, 6MWT (IG 247 ± 94.1 vs. 348 ± 100.1, CG 232 ± 102.8 vs. 333 ± 120.7), SPPB (IG 8.31 ± 2.21 vs. 9.51 ± 2.24, CG 7.95 ± 2.01 vs. 9.08 ± 2.35), 5MWT (IG 0.847 ± 0.31 vs. 0.965 ± 0.3, CG 0.765 ± 0.24 vs 0.879 ± 0.29) all other outcome variables and physical frailty level improved significantly (p p Conclusion Exercise-based CR improves functional and exercise capacity, physical performance, and muscular strength, and reduces physical frailty levels in patients after valve surgery/intervention in the short and medium terms. SPPB score and 5MWT were useful for physical frailty assessment, screening and evaluation of outcomes in a CR setting. Additional benefit from the resistance and balance training could not be confirmed. Trial registration NCT04234087, retrospectively registered 21 January 2020.

Background: Scientific guidelines have been developed to update and harmonize exercise based cardiac rehabilitation (ebCR) in German speaking countries. Key recommendations for ebCR indications have recently been published in part 1 of this journal. The present part 2 updates the evidence with respect to contents and delivery of ebCR in clinical practice, focusing on exercise training (ET), psychological interventions (PI), patient education (PE). In addition, special patients’ groups and new developments, such as telemedical (Tele) or home-based ebCR, are discussed as well. Methods: Generation of evidence and search of literature have been described in part 1. Results: Well documented evidence confirms the prognostic significance of ET in patients with coronary artery disease. Positive clinical effects of ET are described in patients with congestive heart failure, heart valve surgery or intervention, adults with congenital heart disease, and peripheral arterial disease. Specific recommendations for risk stratification and adequate exercise prescription for continuous-, interval-, and strength training are given in detail. PI when added to ebCR did not show significant positive effects in general. There was a positive trend towards reduction in depressive symptoms for “distress management” and “lifestyle changes”. PE is able to increase patients’ knowledge and motivation, as well as behavior changes, regarding physical activity, dietary habits, and smoking cessation. The evidence for distinct ebCR programs in special patients’ groups is less clear. Studies on Tele-CR predominantly included low-risk patients. Hence, it is questionable, whether clinical results derived from studies in conventional ebCR may be transferred to Tele-CR. Conclusions: ET is the cornerstone of ebCR. Additional PI should be included, adjusted to the needs of the individual patient. PE is able to promote patients self-management, empowerment, and motivation. Diversity-sensitive structures should be established to interact with the needs of special patient groups and gender issues. Tele-CR should be further investigated as a valuable tool to implement ebCR more widely and effectively.

IntroductionAtrial fibrillation (AF) is the most common form of cardiac arrhythmia and is associated with a number of comorbidities such as coronary artery disease and heart failure. While physical activity is already implemented in current international guidelines for the prevention and treatment of AF, the precise role of different types of exercise in the management of AF remains to be elucidated. The primary aim of the Cologne ExAfib Trial is to assess the feasibility and safety of different exercise modes in patients diagnosed with paroxysmal AF. Secondary outcomes include assessments of physical function, AF burden, quality of life and inflammation, as well as morphological and cardiac adaptations.Methods and analysisThe study opened for recruitment in September 2019. In the initial pilot phase of this four-armed randomised controlled trial, we aim to enrol 60 patients between 60 years and 80 years of age with paroxysmal AF. After screening and pretesting, patients are randomised into one of the following groups: high-intensity interval training (4×4 min at 75%–85% peak power output (PPO)), moderate-intensity continuous training (25 min at 55%–65% PPO), strength training (whole body, 3 sets of 6–12 repetitions at 70%–90% one repetition maximum [1RM]) or a usual-care control group. Training is performed two times per week for 12 weeks. If the feasibility and safety can be confirmed through the initial pilot phase, the recruitment will be continued and powered for a clinical endpoint.Feasibility and safety are assessed by measures of recruitment and completion, programme tolerance and adherence as well as reported adverse events, including hospitalisation rates. Secondary endpoints are assessed by measures of peak oxygen consumption and the 1RM of selected muscle groups, questionnaires concerning quality of life and AF burden, serum blood samples for the analysis of C reactive protein, interleukin-6, tumour necrosis factor alpha and N-terminal pro-brain natriuretic peptide concentrations and ultrasound for muscle and heart morphology as well as cardiac function.Ethics and disseminationEthics approval was obtained from the ethics committee of the German Sport University Cologne (No.: 175/2018). All procedures performed in studies involving human participants are in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Declaration of Helsinki and its later amendments or comparable ethical standards. Manuscripts will be written based on international authorship guidelines. No professional writers will be commissioned for manuscript drafting. The findings of this study will be published in peer-reviewed journals and presented at leading exercise and medicine conferencesTrial registration numberThe study is registered both at the German and at the WHO trial registers (DRKS00016637); Pre-results.

For the treatment of terminal heart failure, heart transplantation is considered to be the gold standard, leading to significantly improved quality of life and long-time survival. For heart transplant recipients, the development and maintenance of good functional performance and adequate exercise capacity is crucial for renewed participation and integration in self-determined live. In this respect, typical transplant-related alterations must be noted that play a significant role, leading to restrictions both centrally and peripherally. Before patients begin intensive and structured exercise training, a comprehensive diagnosis of their exercise capacity should take place in order to stratify the risks involved and to plan the training units accordingly. Particularly endurance sports and resistance exercises are recommended to counter the effects of the underlying disease and the immunosuppressive medication. The performance level achieved can vary considerably depending on their individual condition, from gentle activity through a non-competitive-level to intensive competitive sports. This paper includes an overview of the current literature on heart transplant recipients, their specific characteristics, as well as typical cardiovascular and musculoskeletal alterations. It also discusses suitable tools for measuring exercise capacity, recommendations for exercise training, required precautions and the performance level usually achieved.

The aim of this literature review was to evaluate existing evidence on exercise-based cardiac rehabilitation (CR) as a treatment option for elderly frail patients with valvular heart disease (VHD). Pubmed database was searched for articles between 1980 and January 2018. From 2623 articles screened, 61 on frailty and VHD and 12 on exercise-based training for patients with VHD were included in the analysis. We studied and described frailty assessment in this patient population. Studies reporting results of exercise training in patients after surgical/interventional VHD treatment were analyzed regarding contents and outcomes. The tools for frailty assessment included fried phenotype frailty index and its modifications, multidimensional geriatric assessment, clinical frailty scale, 5-meter walking test, serum albumin levels, and Katz index of activities of daily living. Frailty assessment in CR settings should be based on functional, objective tests and should have similar components as tools for risk assessment (mobility, muscle mass and strength, independence in daily living, cognitive functions, nutrition, and anxiety and depression evaluation). Participating in comprehensive exercise-based CR could improve short- and long-term outcomes (better quality of life, physical and functional capacity) in frail VHD patients. Such CR program should be led by cardiologist, and its content should include (1) exercise training (endurance and strength training to improve muscle mass, strength, balance, and coordination), (2) nutrition counseling, (3) occupational therapy (to improve independency and cognitive function), (4) psychological counseling to ensure psychosocial health, and (5) social worker counseling (to improve independency). Comprehensive CR could help to prevent, restore, and reduce the severity of frailty as well as to improve outcomes for frail VHD patients after surgery or intervention.

Following implantation of a left ventricular assist device (LVAD), acceptable functional performance is now being achieved; however, peak VO2 and peak work load (watts) remain considerably limited. Maximum physical capacity is essentially dependent on generated cardiac output (CO) and arteriovenous oxygen difference (avDO2 ). We investigated the changes in CO and avDO2 during exercise in LVAD patients with an HVAD pump (HeartWare Inc., Framingham, MA, USA). Approximately 6 weeks after implantation, 20 patients (100% male, 60.8 ± 7.3 years old, BMI 25.7 ± 3.3) underwent a six-minute walk test (6MWT), a cardiopulmonary exercise test (CPET), and noninvasive hemodynamic measurement. The mean six-minute walking distance (6MWD) was 403 m (68% of predicted), and mean peak VO2 was 10.9 mL/kg/min (39% of predicted). Mean total CO improved from 3.8 L at rest to 7.0 L at maximum exercise. The mean avDO2 increased from 7.4 mL/dL (44% of oxygen content) at rest to 13.2 mL/dL (75% of oxygen content) at maximum exercise. There was a significant increase in both total CO (P

Trial design Prospective randomized multicentre interventional study. Methods Individual cardiovascular risk assessment in Ford Company, Germany employees (n = 4.196), using the European Society of Cardiology-Systematic Coronary Risk Evaluation (ESC-SCORE) for classification into three risk groups. Subjects assigned to ESC high-risk group (ESC-SCORE ≥ 5%), without a history of cardiovascular disease were eligible for randomization to a multimodal 15-week intervention programme (INT) or to usual care and followed up for 36 months. Objectives Evaluation of the long-term effects of a risk-adjusted multimodal intervention in high-risk subjects. Primary endpoint: reduction of ESC-SCORE in INT versus usual care. Secondary endpoints: composite of fatal and non-fatal cardiovascular events and time to first cardiovascular event. Statistical analysis: intention-to-treat and per-protocol analysis. Results Four hundred and forty-seven subjects were randomized to INT (n = 224) or to usual care (n = 223). After 36 months ESC-SCORE development favouring INT was observed (INT: 8.70% to 10.03% vs. usual care: 8.49% to 12.09%; p = 0.005; net difference: 18.50%). Moreover, a significant reduction in the composite cardiovascular events was observed: (INT: n = 11 vs. usual care: n = 27). Hazard ratio of intervention versus control was 0.51 (95% confidence interval 0.25–1.03; p = 0.062) in the intention-to-treat analysis and 0.41 (95% confidence interval 0.18–0.90; p = 0.026) in the per-protocol analysis, respectively. No intervention-related adverse events or side-effects were observed. Conclusions Our results demonstrate the efficiency of identifying cardiovascular high-risk subjects by the ESC-SCORE in order to enrol them to a risk adjusted primary prevention programme. This strategy resulted in a significant improvement of ESC-SCORE, as well as a reduction in predefined cardiovascular endpoints in the INT within 36 months. (ISRCTN 23536103.)

Adequate physical and functional performance is an important prerequisite for renewed participation and integration in self-determined private and (where appropriate) professional lives following left ventricular assist device (LVAD) implantation. During cardiac rehabilitation (CR), individually adapted exercise programs aim to increase exercise capacity and functional performance. A retrospective analysis of cardiopulmonary exercise capacity and functional performance in LVAD patients at discharge from a cardiac rehabilitation program was conducted. The results from 68 LVAD patients (59 males, 9 females; 55.9 ± 11.7 years; 47 HVAD, 2 MVAD, 15 HeartMate II, 4 HeartMate 3, and 4 different implanting centers) were included in the analysis. Exercise capacity was assessed using a cardiopulmonary exercise test on a bicycle ergometer (ramp protocol; 10 W/min). The 6-min walk test was used to determine functional performance. At discharge from CR (53 ± 17 days after implantation), the mean peak work load achieved was 62.2 ± 19.3 W (38% of predicted values) or 0.79 ± 0.25 W/kg body weight. The mean cardiopulmonary exercise capacity (relative peak oxygen uptake) was 10.6 ± 5.3 mL/kg/min (37% of predicted values). The 6-min walk distance improved significantly during CR (325 ± 106 to 405 ± 77 m; P

The gold standard for treatment of advanced and terminal heart failure (HF) was long considered to be orthotopic heart transplantation (HTX). HTX leads to a significant improvement in the physical capacity of patients, and thus also to a considerable increase in their quality of life. Survival rates are approximately 85%, 70% and 50% after 1, 5 and 10 years, respectively. The lack of donor organs today, however, means that HTX is now unfortunately only an option for a minority of HF patients, with the gap between organ availability and patients requiring treatment increasing. For a long time there were hardly any other options for the treatment of advanced and terminal HF which had a beneficial prognosis except HTX, but over the past two decades enormous progress has been made in the development of so-called mechanical circulatory support systems (MCS), to the extent that they are now considered an alternative to HTX. In most cases the used MCS systems are left ventricular assist devices (LVAD), and the number of LVAD systems implanted now even exceeds the number of HTX performed by quite a margin. Whereas these systems were previously only implanted temporarily, either until the myocardium recovered (bridge to recovery), or until a donor organ became available (bridge to transplant), today they are increasingly being implanted as a long-term solution (destination therapy). Thus, two different surgical procedures are currently available for the long-term treatment of advanced and terminal HF, with considerably different impacts on patients. Over the long-term course, the establishment and maintenance of an acceptable physical capacity is important for both patient groups, in order to improve their quality of life, as well as to enable them to participate in everyday life. In the following, an assessment of functional and cardiopulmonary exercise capacity, as well as the aspects essential to both target groups regarding clinical condition, hemodynamic principles and exercise will be discussed. The final section includes recommendations and peculiarities regarding target-group-specific exercise training.

The aims of this study were to establish cardiac rehabilitation availability and density, as well as the nature of programmes, and to compare these by European region (geoscheme) and with other high-income countries. A survey was administered to cardiac rehabilitation programmes globally. Cardiac associations were engaged to facilitate programme identification. Density was computed using global burden of disease study ischaemic heart disease incidence estimates. Four high-income countries were selected for comparison ( N = 790 programmes) to European data, and multilevel analyses were performed. Cardiac rehabilitation was available in 40/44 (90.9%) European countries. Data were collected in 37 (94.8% country response rate). A total of 455/1538 (29.6% response rate) programme respondents initiated the survey. Programme volumes (median 300) were greatest in western European countries, but overall were higher than in other high-income countries ( P

Publisher's version (útgefin grein), Background: Despite the epidemic of cardiovascular disease and the benefits of cardiac rehabilitation (CR), availability is known to be insufficient, although this is not quantified. This study ascertained CR availability, volumes and its drivers, and density. Methods: A survey was administered to CR programs globally. Cardiac associations and local champions facilitated program identification. Factors associated with volumes were assessed using generalized linear mixed models, and compared by World Health Organization region. Density (i.e. annual ischemic heart disease [IHD] incidence estimate from Global Burden of Disease study divided by national CR capacity) was computed. Findings: CR was available in 111/203 (54.7%) countries; data were collected in 93 (83.8% country response; N = 1082 surveys, 32.1% program response rate). Availability by region ranged from 80.7% of countries in Europe, to 17.0% in Africa (p < .001). There were 5753 programs globally that could serve 1,655,083 patients/year, despite an estimated 20,279,651 incident IHD cases globally/year. Volume was significantly greater where patients were systematically referred (odds ratio [OR] = 1.36, 95% confidence interval [CI] = 1.35–1.38) and programs offered alternative models (OR = 1.05, 95%CI = 1.04–1.06), and significantly lower with private (OR = .92, 95%CI = .91–.93) or public (OR = .83, 95%CI = .82–84) funding compared to hybrid sources. Median capacity (i.e., number of patients a program could serve annually) was 246/program (Q25-Q75 = 150–390). The absolute density was one CR spot per 11 IHD cases in countries with CR, and 12 globally. Interpretation: CR is available in only half of countries globally. Where offered, capacity is grossly insufficient, such that most patients will not derive the benefits associated with participation., This research was supported by a grant from York University 's Faculty of Health. The funder had no role in study design, data collection, data analysis, interpretation or writing of the report.

Purpose Following MCS implantation adequate functional performance is crucial for participation in self-determined social life. Exercise-based cardiac rehabilitation (CR) is intended to make an important contribution to recovery before patients can be discharged home. It was our aim to evaluate functional performance measured with the six-minute walking distance (6MWD) at the end of inpatient CR and possible influencing factors. Methods Retrospective analysis of monocentric quality assurance data: we included patients (≥18 years old) who underwent MCS implantation between 2006 and 2016 and subsequently completed exercise-based inpatient CR. 6MWD was measured routinely at begin and end of CR. In total the results of 435 patients (54±12 yrs old, 16% female, 42%DCM, 43% ICM, 9% myocarditis) with MCS support (413 LVAD, 17 BVAD, 2 RVAD, 3 TAH) could be analyzed. Results CR began 54±42 days after implantation and lasted 24±6 days. Overall the 6MWD improved significantly from 292±109 to a total of 375±109 m (p Conclusion In patients with MCS systems 6MWD improved significantly during exercise-based inpatient CR regardless from different support types. The reached distance of about 375 m reflects adequate functional performance as prerequisite for the activities of daily living. In the future, randomized and controlled studies should be sought to verify and confirm the effects of exercise-based CR in patients with MCS.

Following implantation of a left ventricular assist device, the build-up and long-term maintenance of adequate exercise capacity and functional performance become crucial. The aim of this study was to observe the development of exercise-related values at different times, as well as to detect possible influencing factors. We performed a prospective single-centre study: 10 patients (63 years, 100% male, body mass index = 27.5, 100% HeartWare) underwent the following diagnostic tests during cardiac rehabilitation and during two subsequent ambulatory visits: 6-min walking test, handgrip strength test, cardiopulmonary exercise test and Minnesota Living with Heart Failure questionnaire. Mean follow-up was 482 days after left ventricular assist device implantation. Significant improvements could be observed between the end of cardiac rehabilitation and ambulatory visit 1; 6-min walking distance increased from 367 to 449 m (p 2 from 10.0 to 11.9 mL/kg/min (p 2 (r = −0.75, p

The implantation of left ventricular assist devices (LVAD) has been established as a successful treatment for terminal heart failure (HF) for many years. Patient benefits include significantly improved survival, as well as improved quality of life. However, peak exercise capacity following LVAD implantation remains considerably restricted. This could be due to the predominate use of continuous-flow pumps, which operate at a fixed rotational speed and do not adapt to exercise conditions. Therefore, current research is focused on whether, and to what extent, adaptations in pump speed can influence and improve patient exercise capacity. We performed a systematic PubMed literature search on this topic, and found 11 relevant studies with 161 patients. Exercise time, peak work load, total cardiac output (TCO), peak oxygen consumption (peak VO2) and, if available, values at the anaerobic threshold (AT) were all taken into consideration. Possible complications were documented. This paper aims to compare the results from these studies in order to discuss the effects of pump speed adaptations on exercise capacity.

Background With an increasing number of left ventricular assist devices (LVADs) being implanted, the need for adequate cardiac rehabilitation (CR) regimens meeting the special needs of these patients arises. Only a few studies have reported experience gained on this topic. Structured CR strategies are poorly implemented. The aim was to evaluate the characteristics, therapeutic needs, and scope of LVAD patients at admission to CR within a greater cohort in order to identify their special CR needs. Methods Retrospective single-center study; 69 LVAD patients (50.7 ± 13.6 y; 59 male; 48 HVAD; 21 HeartMate II) who completed first inpatient CR were included. Patient records were used to document relevant medical information (including the results of a 6-min walk test and a maximal isometric strength test for quadriceps femoral muscles in both legs) and the International Classification of Functioning, Disability and Health for classification of health and health-related domains. Results Patient characteristics demonstrated a heterogeneous group: CR was started 44 ± 38.6 d after implantation; CR duration was 28 ± 9.7 d. Despite similar etiology, physical and psychological condition was diverse, although, overall a high degree of impairment was present, especially in the body function (79.7%) and activity and participation (95.7%) domains. The results demonstrated the need for a highly individualized approach in the somatic and also in the education, psychosocial, and social therapeutic regimes. Conclusion The results demonstrate a heterogeneous group with a high level of impairment and special needs in many CR domains. The development and evaluation of a special highly individualized approach of CR, which meets the special needs of these patients, is needed.

Hintergrund Mit fortschreitendem Alter nehmen sowohl beim Mann als auch der Frau die Fettmasse zu und die Muskelmasse ab. Frauen haben bis zum Eintritt in die Wechseljahre ein deutlich reduziertes Risiko, kardiovaskulare Krankheiten zu entwickeln. Nach der Menopause gleicht sich dieses Risiko dem der Manner an. Grund hierfur sind die metabolischen Wirkungen der weiblichen Sexualhormone. Besonders Ostrogene beeinflussen den Fett- sowie den Proteinstoffwechsel und sind daher fur die Entwicklung bzw. Pravention von Ubergewicht, Typ-2-Diabetes und des metabolischen Syndroms von Bedeutung, die wiederum Risikofaktoren induzieren, die die Entstehung kardiovaskularer Erkrankungen begunstigen.

Following implantation of a left ventricular assist device (LVAD), acceptable functional performance is now being achieved; however, peak VO

Background: Cardiovascular rehabilitation in Germany traditionally is offered as inpatient service often located far from patient’s residence, and ambulatory rehabilitation still represents a minority. The German Registry of Ambulatory Cardiac Rehabilitation (KARREE) was designed to contribute to rehabilitation quality assurance and to evaluate clinical characteristics of patients participating in ambulatory rehabilitation centers. Methods: In four ambulatory rehabilitation centers 2989 patients were consecutively registered from 2008 to 2011 and evaluated with respect to social status, cardiovascular diagnoses and risk factors, psychological status, medication and short term clinical and social outcome. Results: Most patients referred to the ambulatory cardiac rehabilitation had an acute cardiovascular event, with patients after acute coronary syndrome representing the majority (59.9%). Female were strongly underrepresented (16.7%). Patient’s clinical characteristics varied with the age groups evaluated ( 70 years). Whereas the reported physical inactivity, overweight and cigarette smoking was declining with age, diabetes and hypertension significantly increased. Furthermore the reported and evaluated psychosocial stress was declining with age. Regarding the group of patients still employed, 43.5 % were estimated as fit for work directly at the end of the rehabilitation program, whereas a stepwise reintegration into employment was performed in 16.7%. The majority of patients were transferred to ambulatory heart groups or other forms of after care for stabilizing regular physical activity. Conclusions: The large variation of the characteristics of patients participating cardiac rehabilitation underscore the need of an individualized approach for a successful implementation of secondary prevention and reintegration of these patients into their social life.
