Cardiac Rehabilitation in German Speaking Countries of Europe-Evidence-Based Guidelines from Germany, Austria and Switzerland LLKardReha-DACH-Part 2.

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.

[Cardiac Rehabilitation in Patients with Mechanical Circulatory Support]. / Mechanische Herzunterstützungssysteme in der kardiologischen Rehabilitation.

Background Heart failure in a terminal stage is usually treated with a heart transplant or with implantation of ventricular assist devices (VAD). VAD treatment is increasingly chosen as a permanent therapy. Problem The growing number of VAD implants leads to an increased need for rehabilitation programs. The development of standards is essential. So far only a few single center reports with a limited number of patients have been published. Guidelines on this subject are not available. Results A working group of German rehabilitation physicians was installed in order to analyze the problems and to develop strategies for the process of rehabilitation of VAD-patients, ending in a consensus statement 1.The most important aspects of rehabilitation aiming at the safest possible participation in everyday life with a VAD are summarized here.

[Training and educational measures in severe chronic heart failure. Experiences and application to general practice]. / Trainings- und Schulungsmassnahmen bei schwerer chronischer Herzinsuffizienz. Erfahrungen und Umsetzung in der Praxis.

OBJECTIVES: Prognosis and course of severe left ventricular dysfunction have been shown to be influenced positively by exercise training. Yet, physicians have been reluctant to include exercise into therapeutic concepts due to widespread uncertainty about the acceptable intensity of cardiac stress. Standardized exercise programs with proven safety may promote acceptance of this approach. PATIENTS AND METHODS: 25 patients with severe heart failure were enrolled in a PC-controlled interval exercise training on cycle ergometer, lasting 21 minutes five times a week for a 4-week inpatient period. After discharge patients performed incremental daily walking for 3 months. Associated educational measures concerned life-style changing and self-controls. RESULTS: None of the patients had to interrupt the training because of side effects. 3 weeks and 3 months after starting exercise training there was an increase of peak VO2 from 13.4 +/- 2.8 to 14.5 +/- 3.8 (p < 0.05) and 15.3 +/- 3.2 ml/kg/min (p < 0.01), respectively, and an increase of ventilatory anaerobic threshold (VAT) from 9.3 +/- 1.9 to 10.0 +/- 2.3 (p < 0.05) and 11.3 +/- 2.2 ml/kg/min (p < 0.001), respectively. The improved aerobic capacity corresponded to a 9.3% increase in the results of the 6-minute walk test in the 4th week (n.s.). During out-patient period, the walking could be increased from 37 to 58 minutes daily. The physical quality of life was significantly improved after 3 months. There was no hospital admission due to heart failure. CONCLUSION: Exercise training in the therapy of severe heart failure is safe and increases the aerobic capacity. Associated educational measures may be able to minimize the danger of wrong exercise techniques and to reduce the rate of hospital readmissions.
