Cardiac Rehabilitation in German Speaking Countries of Europe-Evidence-Based Guidelines from Germany, Austria and Switzerland LLKardReha-DACH-Part 1.

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 <40%) especially benefit in terms of exercise capacity and health-related quality of life. Patients with other cardiovascular diseases also benefit from CR-participation, but the scientific evidence is less clear. There is increasing evidence that the beneficial effect of CR strongly depends on "treatment intensity" including medical supervision, treatment of cardiovascular risk factors, information and education, and a minimum of individually adapted exercise volume. Additional psychologic interventions should be performed on the basis of individual needs. CONCLUSIONS: These guidelines reinforce the substantial benefit of CR in specific clinical indications, but also describe remaining deficits in CR-delivery in clinical practice as well as in CR-science with respect to methodology and presentation.

[Rehab Aftercare 'New Credo' in the Cardiac Follow-Up Rehabilitation]. / Nachsorge 'Neues Credo' in der kardiologischen Anschlussrehabilitation.

PURPOSE: Physical inactivity is considered the most important modifiable risk factor of cardio-vascular diseases. Therefore medical rehabilitation is focused on the improvement of physical activity. To maintain physical activity after rehabilitation aftercare strategies are necessary which help to transfer the skills learned during rehabilitation into daily routine. In this study the aftercare concept "Neues Credo" which has been evaluated several times has been implemented and evaluated into cardiological follow-up rehabilitation. METHODS: Prospective, controlled, multicentre study with 4 cardiological rehabilitation institutions. INCLUSION CRITERIA: rehabilitants with initial diagnosis from the ICD groups I20-25 and I34-43. In the first phase of the study, patients received standard rehabilitation and standard aftercare (control group (KG)). In the second phase, patients received rehabilitation based on the conditions of "Neues Credo" with the focus on increasing physical activity (intervention group (IG)). Data for evaluation were collected by paper-and-pencil questionnaires at 3 points in time. Primary outcome variable: restriction in participation (IMET); secondary outcome variables: depression (CES-D), several scales of subjective health and physical activity. Analysis of variance with repeated measures was used for the evaluation of long-term effects. RESULTS: Complete data could be evaluated from 152 patients of the IG and from 165 patients of the KG. At the end of rehabilitation both IG and KG showed improvements in outcome variables. In the period after rehabilitation patients in the IG improved their physical activity significantly more often than members of the KG (66 vs. 42%, p<0,01), they showed more physical activity than the KG (p=0,040) and they performed endurance sports more often (58 vs. 38%, p<0,01). The primary outcome of participation shows significant improvements in both groups (p<0,01) 12 months after the rehabilitation, difference between groups did not reach statistical significance but indicated a clear tendency in favour of the IG. Similar trends could be found for the secondary outcome-data CONCLUSION: In this study, the "Neues Credo" was applied and evaluated in cardiologic rehabilitation for the first time. Participants reported high practicability and high satisfaction. Health- related outcomes show a trend of positive effects in favour of the IG, but the interaction effects did not reach statistical significance in most cases. Regarding physical activity the intervention group shows clear advantage and will probably benefit from the long-term effects of regular endurance training.

Inpatient rehabilitation for adult patients with Marfan syndrome: an observational pilot study.

BACKGROUND: Advances in medical, interventional and surgical treatment have increased average life expectancy of patients with congenital heart defects. As a result a new group of adult patients with congenital cardiac defects requires medical rehabilitation. Patients with Marfan syndrome (MFS) are a relevant group among these patients. So far, no reports on the effectiveness of specialized rehabilitation programmes for MFS patients exist. We implemented an inpatient 3-week rehabilitation program for MFS patients at the Muehlenberg-Clinic for rehabilitation and assessed the medical safety as well as the impact of the program on physical fitness and psychological wellbeing of participants by means of an observational pilot study. The comprehensive multidisciplinary program included medical, physiotherapeutic, psychological and social issues. Two groups including 8 and 10 individuals with verified MFS attended the programme. Medically adverse events that occurred during the rehabilitation were registered. Adverse events were defined as: any new cardiac arrhythmias such as atrial fibrillation, ventricular tachycardia, cardiac syncope or any complications located at the aorta. Psychological assessment was performed using Short Form-36 (SF-36), hospital anxiety and depression scale and other psychometric questionnaires. Medical examinations included assessment of maximum power in bicycle ergometry. All assessments were performed at the beginning and at the end of the rehabilitation. Psychometric assessments were repeated 1 year after the end of the programme for both groups, respectively. RESULTS: Patients were highly satisfied with the programme and improved in almost all psychological and physical fitness assessments. The pre-post-comparison resulted in significant positive changes for mental health (p < .001 for SF-36 Mental Health), fatigue (p < .05 for Fatigue Severity Scale), nociception (p < .05 for SF-36 Pain) and vitality (p < .05 for SF-36 Vitality). Physical fitness improved from admission to discharge (p < .001 for maximum power in bicycle ergometry, p < .05 for maximum nordic walking distance). Considerable improvements persisted through 1 year follow-up. Medical assessments excluded medical problems or adverse events caused by participation in the programme. CONCLUSIONS: In our study, inpatient rehabilitation was both safe and helpful for MFS patients. They benefited in terms of physical fitness, health related quality of life and in terms of psychological wellbeing. An evaluation of the efficacy of the programme in a controlled design as well as further conceptual improvements of our current program is desirable.

A web-based peer-modeling intervention aimed at lifestyle changes in patients with coronary heart disease and chronic back pain: sequential controlled trial.

BACKGROUND: Traditional secondary prevention programs often fail to produce sustainable behavioral changes in everyday life. Peer-modeling interventions and integration of peer experiences in health education are a promising way to improve long-term effects in behavior modification. However, effects of peer support modeling on behavioral change have not been evaluated yet. Therefore, we implemented and evaluated a website featuring patient narratives about successful lifestyle changes. OBJECTIVE: Our aim is to examine the effects of using Web-based patient narratives about successful lifestyle change on improvements in physical activity and eating behavior for patients with coronary heart disease and chronic back pain 3 months after participation in a rehabilitation program. METHODS: The lebensstil-aendern ("lifestyle-change") website is a nonrestricted, no-cost, German language website that provides more than 1000 video, audio, and text clips from interviews with people with coronary heart disease and chronic back pain. To test efficacy, we conducted a sequential controlled trial and recruited patients with coronary heart disease and chronic back pain from 7 inpatient rehabilitation centers in Germany. The intervention group attended a presentation on the website; the control group did not. Physical activity and eating behavior were assessed by questionnaire during the rehabilitation program and 12 weeks later. Analyses were conducted based on an intention-to-treat and an as-treated protocol. RESULTS: A total of 699 patients were enrolled and 571 cases were included in the analyses (control: n=313, intervention: n=258; female: 51.1%, 292/571; age: mean 53.2, SD 8.6 years; chronic back pain: 62.5%, 357/571). Website usage in the intervention group was 46.1% (119/258). In total, 141 trial participants used the website. Independent t tests based on the intention-to-treat protocol only demonstrated nonsignificant trends in behavioral change related to physical activity and eating behavior. Multivariate regression analyses confirmed belonging to the intervention group was an independent predictor of self-reported improvements in physical activity regularity (ß=.09, P=.03) and using less fat for cooking (ß=.09, P=.04). In independent t tests based on the as-treated protocol, website use was associated with higher self-reported improvements in integrating physical activity into daily routine (d=0.22, P=.02), in physical activity regularity (d=0.23, P=.02), and in using less fat for cooking (d=0.21, P=.03). Multivariate regression analyses revealed that using the website at least 3 times was the only factor associated with improved lifestyle behaviors. CONCLUSIONS: Usage of the lebensstil-aendern website corresponds to more positive lifestyle changes. However, as-treated analyses do not allow for differentiating between causal effects and selection bias. Despite these limitations, the trial indicates that more than occasional website usage is necessary to reach dose-response efficacy. Therefore, future studies should concentrate on strategies to improve adherence to Web-based interventions and to encourage more frequent usage of these programs.

Outcomes of cardiac rehabilitation with versus without a follow-up intervention rendered by telephone (Luebeck follow-up trial): overall and gender-specific effects.

The effects of a nurse-managed secondary prevention program for patients after acute cardiac events were examined. Special interest was given to gender-specific results. The design was a prospective, randomized, controlled trial involving 343 patients following 3 weeks of inpatient cardiac rehabilitation, randomly assigned to either of two study groups. Patients in the treatment group were contacted monthly by phone over 1 year. The main goals of the intervention were the reduction of behavioural coronary risk factors and enhancing quality of life. The program was conducted by specially trained nurses. The control group received written information only. Primary outcome was the Framingham risk score. Follow-up examination after 12 months was completed by 297 patients. Patients in the intervention group showed lower Framingham risk scores as compared to controls. Separate analyses by sex revealed that this was mostly due to the men in the sample. Women, on the other hand, showed a significant rise of clinically relevant anxiety/depressiveness in the control but not in the intervention group; in males there were no differences between study conditions. In conclusion, telephone counselling by specially trained nurses seems a cost-effective way to achieve a lasting reduction in cardiac risk factors and to maintain the effects of cardiac rehabilitation.
