    ABSTRACT: Adherence to medical advice, driven by high patient motivation, could lead to a significant reduction in risk factors during cardiac rehabilitation. During a 1-year period, 9082 patients were admitted to six cardiac rehabilitation centres. A total of 1195 highly motivated subjects were selected based on their reliable completion of a survey regarding cardiac risk factors. Study subjects had lower risk factors at baseline compared with a contemporary Austrian database. At discharge from the rehabilitation programme subjects showed further reductions in median weight, low-density lipoprotein cholesterol, blood pressure and resting pulse rate (due to increased levels of daily exercise). Smoking also decreased. Most of these changes were still significant after 1 year. The risk factors in these highly motivated patients were low to begin with and were further reduced by an inpatient rehabilitation programme. The content and method of delivery of this programme seem to be effective. Efforts should focus on increasing motivation.

    ABSTRACT: Despite the increasing use of left ventricular assist devices (LVADs) in terminal heart failure, cardiac rehabilitation protocols have not yet been documented in larger LVAD patient cohorts. The aim of this study was to investigate safety and efficacy of exercise training during a rehabilitation programme after post-operative discharge of LVAD patients.

    ABSTRACT: Initiation of a long-term improvement of cardiac risk factors is one of the major aims of a cardiac rehabilitation/secondary prevention programme. The Health Guide collected data in terms of cardiac risk factors: blood pressure, resting pulse, total cholesterol, LDL cholesterol, body weight, physical activity and number of cigarettes at admission and discharge after a stationary rehabilitation programme and every 3 months. After 12 months the Health Guides were returned. In the prospective study 2664 patients (71.8% men, age: MV = 62.94 years, SD = 9.96; 28% women, MV = 67.59 years, SD = 9.53) with coronary heart disease (CHD) were included. All cardiac risk factors documented by the Health Guide improved during the cardiac rehabilitation programme. After one year, risk factors were significantly lower than at admission, apart from total cholesterol. The individual goal in terms of body weight and LDL cholesterol was partially achieved after the rehabilitation programme and maintained after one year. In the investigation years, 2004-2007, the cholesterol and blood pressure were significantly lower than in the years 2000-2003. The use of a Health Guide resulted in an improved long-term effect of a cardiac rehabilitation/secondary prevention programme. It is a simple and cheap intervention and can help in the guidance of the patients.

    ABSTRACT: Abstract Background The goal of cardiac rehabilitation programs is not only to prolong life but also to improve physical functioning, symptoms, well-being, and health-related quality of life (HRQL). The aim of this study was to document the long-term effect of a 1-month inpatient cardiac rehabilitation intervention on HRQL in Austria. Methods Patients (N = 487, 64.7% male, age 60.9 ± 12.5 SD years) after myocardial infarction, with or without percutaneous interventions, coronary artery bypass grafting or valve surgery underwent inpatient cardiac rehabilitation and were included in this long-term observational study (two years follow-up). HRQL was measured with both the MacNew Heart Disease Quality of Life Instrument [MacNew] and EuroQoL-5D [EQ-5D]. Results All MacNew scale scores improved significantly (p < 0.001) and exceeded the minimal important difference (0.5 MacNew points) by the end of rehabilitation. Although all MacNew scale scores deteriorated significantly over the two year follow-up period (p < .001), all MacNew scale scores still remained significantly higher than the pre-rehabilitation values. The mean improvement after two years in the MacNew social scale exceeded the minimal important difference while MacNew scale scores greater than the minimal important difference were reported by 40-49% of the patients. Two years after rehabilitation the mean improvement in the EQ-5D Visual Analogue Scale score was not significant with no significant change in the proportion of patients reporting problems at this time. Conclusion These findings provide a first indication that two years following inpatient cardiac rehabilitation in Austria, the long-term improvements in HRQL are statistically significant and clinically relevant for almost 50% of the patients. Future controlled randomized trials comparing different cardiac rehabilitation programs are needed.

    ABSTRACT: The goal of cardiac rehabilitation programs is not only to prolong life, but also to improve physical functioning, symptoms, wellbeing and health-related quality of life (HRQL). The aim of the study was to document short-term outcomes of cardiac rehabilitation programs in Austria. Consecutive patients (N = 487, 64.7% male, age 60.9 +/- 12.5 SD years) after myocardial infarction (MI), with or without percutaneous interventions (PCI), coronary artery bypass grafting (CABG) or heart valve surgery (HVS), referred to the six inpatient rehabilitation centers of the Austrian PVA insurance company, were included in the study. Exercise capacity, risk factors and HRQL (MacNew Heart Disease Quality of Life Instrument [MacNew] and EuroQoL-5D [EQ-5D]) were measured at the beginning and end of the 4-week inpatient cardiac rehabilitation program. Global HRQL (MacNew) improved significantly over time in all patients combined (+0.75 +/- 0.88 SD, T = -16.99, df = 394, p < .001) and exceeded the minimal important difference. Patients with CABG, HVS or MI without PCI showed the greatest improvements in global HRQL after cardiac rehabilitation (p < .02). Blood pressure, cholesterol, triglyceride, body mass index, waist circumference improved significantly (all p < .001). These findings provide evidence that the improvements in HRQL and risk factors following cardiac rehabilitation in Austria are clinically important. HRQL should become a standard outcome parameter in cardiac rehabilitation.
