Cardiac rehabilitation in Austria: long term health-related quality of life outcomes

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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].</p> <p>Results</p> <p>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.</p> <p>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.</p> <p>Conclusion</p> <p>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.</p

Sensory Integration Regulating Male Courtship Behavior in Drosophila

The courtship behavior of Drosophila melanogaster serves as an excellent model system to study how complex innate behaviors are controlled by the nervous system. To understand how the underlying neural network controls this behavior, it is not sufficient to unravel its architecture, but also crucial to decipher its logic. By systematic analysis of how variations in sensory inputs alter the courtship behavior of a naïve male in the single-choice courtship paradigm, we derive a model describing the logic of the network that integrates the various sensory stimuli and elicits this complex innate behavior. This approach and the model derived from it distinguish (i) between initiation and maintenance of courtship, (ii) between courtship in daylight and in the dark, where the male uses a scanning strategy to retrieve the decamping female, and (iii) between courtship towards receptive virgin females and mature males. The last distinction demonstrates that sexual orientation of the courting male, in the absence of discriminatory visual cues, depends on the integration of gustatory and behavioral feedback inputs, but not on olfactory signals from the courted animal. The model will complement studies on the connectivity and intrinsic properties of the neurons forming the circuitry that regulates male courtship behavior

Wirksamkeit der umfassenden kardiologischen Rehabilitation und Sekundärprävention: klinische und epidemiologische Evidenz

Zusammenfassung Die umfassende kardiologische Rehabilitation ist die Summe von koordinierten Maßnahmen, welche die Folgen von Herzerkrankungen vermindern, die Morbidität und Mortalität reduzieren und die gesundheitsbezogene Lebensqualität einschließlich der psychosozialen Situation der Patienten verbessern sollen. Dazu ist die Bereitstellung strukturierter sekundärpräventiver Strategien besonders wichtig. Schwerpunkte dieser Maßnahmen sind die Trainingstherapie und Aktivitätsberatung sowie Ernährungstherapie und -beratung, Raucherentwöhnung, psychosoziale Intervention und Pharmakotherapie (Ades 2001)

Change in health-related quality of life in patients with coronary artery disease predicts 4-year mortality

AIMS: Self-reported health-related quality of life (HRQL) and changes in HRQL have been shown to predict mortality and/or adverse events in patients with coronary artery disease. MacNew Heart Disease HRQL questionnaire scores were examined as predictors of 4-year all-cause mortality. METHODS: Following referral for angioplasty in 385 patients with coronary artery disease, data were analyzed for differences in all-cause mortality by MacNew Global and subscale baseline and 1- and 3-month change scores (deteriorated ≥0.50; unchanged (-0.49 to +0.49); and improved ≥0.50 points). RESULTS: Mean baseline, 1-month, and 3-month MacNew Global and subscale scores were similar in survivors and non-survivors. Mean 1- and 3-month Global and emotional subscale and mean 1-month social subscale change scores decreased more in non-survivors than survivors. Compared with patients whose Global MacNew HRQL scores improved at one month, 4-year all-cause mortality hazard ratio (HR) was higher in patients whose HRQL deteriorated (HR, 1.70, 95% CI, 1.09, 2.65; p=0.021). Compared with patients whose Global MacNew HRQL improved at three months, 4-year all-cause mortality was higher in both patients whose HRQL had deteriorated (HR, 2.07, 95% CI, 1.29, 3.32; p=0.003) and patients with unchanged HRQL (HR, 2.62, 95% CI, 1.11, 6.17; p=0.028). CONCLUSIONS: A deterioration of ≥0.50 points in MacNew HRQL Global scores at both one and three months is predictive of 4-year all-cause mortality. Serial HRQL information may be useful to identify patients at higher risk for adverse cardiac events and mortality and may have implications for determining follow-up frequency and treatment in individual patients

Psychometric properties of the MacNew heart disease health-related quality of life instrument in patients with heart failure

RATIONALE, AIMS AND OBJECTIVES: Heart failure (HF) is a severe chronic disease and impairs health-related quality of life (HRQL). While validated specific HRQL instruments are required for evaluation of treatment and rehabilitation in patients with HF, a single validated measure to document changes in HRQL for patients with different heart disease diagnoses would be invaluable. The purpose of this analysis was the psychometric analysis of the German MacNew Heart Disease Questionnaire (MacNew) in HF patients, which has previously been shown to be reliable and valid in patients with myocardial infarction, angina pectoris and arrhythmia. METHODS: We recruited 89 patients (61.7+/-11.5 years; 84.3% male) in two Austrian and one Swiss cardiology department with documented HF (effect sizes 28.9+/-10.1%). The self-administered MacNew, the Short Form-36 (SF-36) and the Hospital Anxiety and Depression Scale were completed. Internal consistency reliability (Cronbach's alpha), discriminative and evaluative validity were assessed. RESULTS: Cronbach's alpha exceeded 0.80. Each MacNew scale differentiated between patients with and without anxiety (3.9+/-1.0 vs. 5.3+/-0.8, all P0.70 for a subsample attending a 12-week outpatient rehabilitation programme. CONCLUSIONS: The German language version of the MacNew demonstrates consistently acceptable psychometric properties of reliability, validity and responsiveness in patients with documented HF. Together with previous documentation of reliability, validity and responsive, these findings strengthen the argument for the MacNew as a potential 'core' HRQL measure, at least in the German language

Secondary prevention through cardiac rehabilitation: from knowledge to implementation. A position paper from the Cardiac Rehabilitation Section of the European Association of Cardiovascular Prevention and Rehabilitation

Increasing awareness of the importance of cardiovascular prevention is not yet matched by the resources and actions within health care systems. Recent publication of the European Commission's European Heart Health Charter in 2008 prompts a review of the role of cardiac rehabilitation (CR) to cardiovascular health outcomes. Secondary prevention through exercise-based CR is the intervention with the best scientific evidence to contribute to decrease morbidity and mortality in coronary artery disease, in particular after myocardial infarction but also incorporating cardiac interventions and chronic stable heart failure. The present position paper aims to provide the practical recommendations on the core components and goals of CR intervention in different cardiovascular conditions, to assist in the design and development of the programmes, and to support healthcare providers, insurers, policy makers and consumers in the recognition of the comprehensive nature of CR. Those charged with responsibility for secondary prevention of cardiovascular disease, whether at European, national or individual centre level, need to consider where and how structured programmes of CR can be delivered to all patients eligible. Thus a novel, disease-oriented document has been generated, where all components of CR for cardiovascular conditions have been revised, presenting both well-established and controversial aspects. A general table applicable to all cardiovascular conditions and specific tables for each clinical disease have been created and commented
