Objective: Newer generation left ventricular assist devices (LVADs) are established for long-term support. The aim of this multi-modal intervention was to improve the body weight, exercise tolerance and psychosocial status in outpatients on long-term LVAD support., Methods: Seventy patients participated in this non-randomized intervention study [intervention group (IGr) n = 34; control group (CGr) n = 36] over 18 months (T1-T4); the baseline sample characteristics showed no differences between groups. Dietary counselling and weight management intervention was performed by a dietician based on a specific algorithm. Physical reconditioning followed a home ergometry protocol and was supplemented by psychosocial counselling. The outcomes were measured based on the body mass index (BMI), cardiopulmonary exercise testing and self-report [hospital anxiety and depression scale (HADS), SF-36]., Results: The intervention showed a strong positive effect on nutrition and weight management [95% confidence interval (CI): -0.71-0.69; effect size (ES): 0.907; P = 0.02)], resulting in the normal BMI (kg/m(2)) values in the IGr (T1: 24.0 ± 0.6; T4: 24.5 ± 1.1; P = 0.35) compared with a significant BMI increase in the CGr (T1: 23.8 ± 0.6; T4: 29.7 ± 0.8; P = 0.05). Significant differences appeared regarding exercise tolerance (VO(2)max/% predicted) in favour of IGr patients (IGr: 69 ± 2.9; CGr 62 ± 3.7; P = 0.04). This increase was reflected by patients' self-reporting based on the SF-36 physical component score (IGr: P = 0.04; CGr: P = 0.54). SF-36 psychosocial component scores showed no changes for both groups. However, CGr showed a tendency for increased anxiety scores relative to their counterparts (IGr: 4.95 ± 0.4; CGr: 6.6 ± 0.9; P = 0.03)., Conclusions: IGr patients showed a strong benefit from a multi-modal intervention, including dietary counselling, controlled exercise and psychosocial support. Dietary counselling holds potential to prevent obesity in this patient population.

After acute hospital therapy of myocardial infarction or bypass surgery the patient in Germany will be treated using an inpatient rehabilitation programme for 3-4 weeks. One year later only 10% of them are still active in outpatients groups. In our study 61 cardiac patients performed an one-year outpatient rehabilitation (instead of 4 weeks inpatient) programme with intense supervised exercise and behaviour therapy. The money input per patient was the same for the usual care 4 weeks inpatient (6000 DM) as for 1 year outpatient rehabilitation (5800 DM). The exercise capacity per heart rate-blood pressure-product was increased by 43% (p > 0.01) after 12 months. The maximum exercise capacity was reached in the 57th week. Without increased medical treatment, cholesterol and LDL-cholesterol were reduced after 12 months by 3.9% down to 195 +/- 25 mg/dl or by 6.6% down to 122 +/- 21 mg/dl, respectively (n.s.). HDL-cholesterol increased by 2.8% to 48 +/- 8 mg/dl (n.s.). This study shows results similar to outpatient rehabilitation programmes in the United States or in Sweden. The long intervention time and the intensity are main factors for the success of cardiac rehabilitation and patient health. Financial resources should primarily be concentrated on long-term outpatient rehabilitation programmes.

In Germany cardiac rehabilitation contains a comprehensive 3 to 4 week inpatient program. The aim of our study was to perform an outpatient long-term rehabilitation including intense exercise and behavior therapy. In this setting the health benefits could be increased over the first 6 months. Hundred and twelve patients (94 men and 18 women, age 55 +/- 11 years) after myocardial infarction (52%), bypass-surgery (37%), PTCA (23%), and others (15%) were included in the ongoing study. Cholesterol and LDL-cholesterol diminished significantly. HDL-cholesterol was increased significantly after 6 months. The endurance exercise capacity per rate-pressure-product was increased by 46% during the 6 months period. The intake of cholesterol could significantly be diminished from 307 +/- 25 to 258 +/- 19 mg per day. Five of 16 patients became free from smoking. The first results from the long-term outpatient program show that the time of intervention and also the intensity of the medical, exercise and the behavior therapy are important factors for a successful rehabilitation.
