Multimodal prehabilitation for major surgery in elderly patients to lower complications: protocol of a randomised, prospective, multicentre, multidisciplinary trial (PREHABIL Trial).

INTRODUCTION: The global volume of surgery is growing and the population ageing, and economic pressure is rising. Major surgery is associated with relevant morbidity and mortality. Postoperative reduction in physiological and functional capacity is especially marked in the elderly, multimorbid patient with low fitness level, sarcopenia and malnutrition. Interventions aiming to optimise the patient prior to surgery (prehabilitation) may reduce postoperative complications and consequently reduce health costs. METHODS AND ANALYSIS: This is a multicentre, multidisciplinary, prospective, 2-arm parallel-group, randomised, controlled trial with blinded outcome assessment. Primary outcome is the Comprehensive Complications Index at 30 days. Within 3 years, we aim to include 2×233 patients with a proven fitness deficit undergoing major surgery to be randomised using a computer-generated random numbers and a minimisation technique. The study intervention consists of a structured, multimodal, multidisciplinary prehabilitation programme over 2-4 weeks addressing deficits in physical fitness and nutrition, diabetes control, correction of anaemia and smoking cessation versus standard of care. ETHICS AND DISSEMINATION: The PREHABIL trial has been approved by the responsible ethics committee (Kantonale Ethikkomission Bern, project ID 2020-01690). All participants provide written informed consent prior to participation. Participant recruitment began in February 2022 (10 and 8 patients analysed at time of submission), with anticipated completion in 2025. Publication of the results in peer-reviewed scientific journals are expected in late 2025. TRIAL REGISTRATION NUMBER: NCT04461301.

Exercise intensity assessment and prescription in cardiovascular rehabilitation and beyond: why and how: a position statement from the Secondary Prevention and Rehabilitation Section of the European Association of Preventive Cardiology.

A proper determination of the exercise intensity is important for the rehabilitation of patients with cardiovascular disease (CVD) since it affects the effectiveness and medical safety of exercise training. In 2013, the European Association of Preventive Cardiology (EAPC), together with the American Association of Cardiovascular and Pulmonary Rehabilitation and the Canadian Association of Cardiac Rehabilitation, published a position statement on aerobic exercise intensity assessment and prescription in cardiovascular rehabilitation (CR). Since this publication, many subsequent papers were published concerning the determination of the exercise intensity in CR, in which some controversies were revealed and some of the commonly applied concepts were further refined. Moreover, how to determine the exercise intensity during resistance training was not covered in this position paper. In light of these new findings, an update on how to determine the exercise intensity for patients with CVD is mandatory, both for aerobic and resistance exercises. In this EAPC position paper, it will be explained in detail which objective and subjective methods for CR exercise intensity determination exist for aerobic and resistance training, together with their (dis)advantages and practical applications.

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.

[Exercise Training and Physical Activity in Patients with Heart Failure]. / Bewegungstherapie und körperliche Aktivität bei Patienten mit Herzinsuffizienz.

Exercise Training and Physical Activity in Patients with Heart Failure Abstract. Heart failure is a clinical syndrome with different etiologies and phenotypes. For all forms, supervised exercise training and individual physical activity are class IA recommendations in current guidelines. Exercise training can start in the hospital, immediately after stabilization of acute heart failure (phase I). After discharge, it can continue in a stationary or ambulatory prevention and rehabilitation program (phase II). Typical components are endurance, resistance and respiratory training. Health insurances cover costs for three to six months. Patients with implantable cardioverter defibrillators or left ventricular assist devices may train in experienced centers. Besides muscular reconditioning, a major goal of phase II is to increase health literacy to improve long-term adherence to physical activity. In phase III, heart groups offer support.

Effects of health risk assessment and counselling on physical activity in older people: A pragmatic randomised trial.

BACKGROUND: Interventions to increase physical activity (PA) among older community-dwelling adults may be enhanced by using multidimensional health risk assessment (HRA) as a basis for PA counselling. METHODS: The study was conducted among nondisabled but mostly frail persons 65 years of age and older at an ambulatory geriatric clinic in Bucharest, Romania. From May to July 2014, 200 participants were randomly allocated to intervention and control groups. Intervention group participants completed an initial HRA questionnaire and then had monthly counselling sessions with a geriatrician over a period of six months that were aimed at increasing low or maintaining higher PA. Counselling also addressed the older persons' concomitant health risks and problems. The primary outcome was PA at six months (November 2014 to February 2015) evaluated with the International Physical Activity Questionnaire. RESULTS: At baseline, PA levels were similar in intervention and control groups (median 1089.0, and 1053.0 MET [metabolic equivalent of task] minutes per week, interquartile ranges 606.0-1401.7, and 544.5-1512.7 MET minutes per week, respectively). Persons in the intervention group had an average of 11.2 concomitant health problems and risks (e.g., pain, depressive mood, hypertension). At six months, PA increased in the intervention group by a median of 180.0 MET minutes per week (95% confidence interval (CI) 43.4-316.6, p = 0.01) to 1248.8 MET minutes per week. In the control group, PA decreased by a median of 346.5 MET minutes per week (95% CI 178.4-514.6, p<0.001) to 693.0 MET minutes per week due to a seasonal effect, resulting in a difference of 420.0 MET minutes per week (95% CI 212.7-627.3, p< 0.001) between groups. CONCLUSION: The use of HRA to inform individualized PA counselling is a promising method for achieving improvements in PA, and ultimately health and longevity among large groups of community-dwelling older persons.

A EUropean study on effectiveness and sustainability of current Cardiac Rehabilitation programmes in the Elderly: Design of the EU-CaRE randomised controlled trial.

BACKGROUND: Cardiac rehabilitation (CR) is an evidence-based intervention to increase survival and quality of life. Yet studies consistently show that elderly patients are less frequently referred to CR, show less uptake and more often drop out of CR programmes. DESIGN: The European study on effectiveness and sustainability of current cardiac rehabilitation programmes in the elderly (EU-CaRE) project consists of an observational study and an open prospective, investigator-initiated multicentre randomised controlled trial (RCT) involving mobile telemonitoring guided CR (mCR). OBJECTIVE: The aim of EU-CaRE is to map the efficiency of current CR of the elderly in Europe, and to investigate whether mCR is an effective alternative in terms of efficacy, adherence and sustainability. METHODS AND RESULTS: The EU-CaRE study includes patients aged 65 years or older with ischaemic heart disease or who have undergone heart valve surgery. A total of 1760 patients participating in existing CR programmes in eight regions of Europe will be included. Of patients declining regular CR, 238 will be included in the RCT and randomised in two study arms. The experimental group (mCR) will receive a personalised home-based programme while the control group will receive no advice or coaching throughout the study period. Outcomes will be assessed after the end of CR and at 12 months follow-up. The primary outcome is VO2peak and secondary outcomes include variables describing CR uptake, adherence, efficacy and sustainability. CONCLUSION: The study will provide important information to improve CR in the elderly. The EU-CaRE RCT is the first European multicentre study of mCR as an alternative for elderly patients not attending usual CR.

Costs and yield of a 15-month preparticipation cardiovascular examination with ECG in 1070 young athletes in Switzerland: implications for routine ECG screening.

BACKGROUND: The usefulness and modalities of cardiovascular screening in young athletes remain controversial, particularly concerning the role of 12-lead ECG. One of the reasons refers to the presumed false-positive ECGs requiring additional examinations and higher costs. Our study aimed to assess the total costs and yield of a preparticipation cardiovascular examination with ECG in young athletes in Switzerland. METHODS: Athletes aged 14-35 years were examined according to the 2005 European Society of Cardiology (ESC) protocol. ECGs were interpreted based on the 2010 ESC-adapted recommendations. The costs of the overall screening programme until diagnosis were calculated according to Swiss medical rates. RESULTS: A total of 1070 athletes were examined (75% men, 19.7±6.3 years) over a 15-month period. Among them, 67 (6.3%) required further examinations: 14 (1.3%) due to medical history, 15 (1.4%) due to physical examination and 42 (3.9%) because of abnormal ECG findings. A previously unknown cardiac abnormality was established in 11 athletes (1.0%). In four athletes (0.4%), the abnormality may potentially lead to sudden cardiac death and all of them were identified by ECG alone. The cost was 157,464 Swiss francs (CHF) for the overall programme, CHF147 per athlete and CHF14,315  per finding. CONCLUSIONS: Cardiovascular preparticipation examination in young athletes using modern and athlete-specific criteria for interpreting ECG is feasible in Switzerland at reasonable cost. ECG alone is used to detect all potentially lethal cardiac diseases. The results of our study support the inclusion of ECG in routine preparticipation screening.

Cardiac magnetic resonance assessment of left and right ventricular morphologic and functional adaptations in professional soccer players.

BACKGROUND: Professional, long-term physical training is associated with cardiac morphologic and functional changes that depend on the type of exercise performed. So far, the specific effect of soccer training on cardiac morphology has not been investigated with cardiac magnetic resonance imaging (CMRI). We sought to use CMRI to study left ventricular (LV) and right ventricular (RV) morphologic and functional adaptations in professional soccer players. METHODS: Twenty-nine male professional soccer players (mean age 24.6 +/- 3.9 years, range 18-31 years) in different playing positions and 29 nonathlete male controls (27.0 +/- 3.7 years, 21-34 years) underwent CMRI. Electrocardiographic-gated steady-state free-precession cine CMRI was used to measure myocardial mass (MM), end-diastolic volume (EDV) and end-systolic volume, stroke volume (SV), ejection fraction, and cardiac index at rest. We calculated the ventricular remodeling index (RI) to describe the pattern of cardiac hypertrophy. RESULTS: Ventricular volume and mass indices were significantly (P < .001) higher in athletes. LVEDV and RVEDV on MRI was above normal in 27/29 athletes. There was a strong positive correlation between EDV and myocardial mass (P < .01). The LVRI and RVRI were similar (0.73 +/- 0.1 g/mL; 0.22 +/- 0.01 g/mL) to that of controls (0.71 +/- 0.1 g/mL; 0.22 +/- 0.01 g/mL). No significant differences were observed for LV ejection fraction and cardiac index. Neither the comparison of athletes in different playing positions nor the comparison of younger and older players revealed statistically significant differences. CONCLUSION: Cardiac magnetic resonance imaging measurements enable studying the mechanisms of LV and RV adaptation in professional soccer players and reflect the ventricular response to combined endurance and strength based training.
