Angiotensin II blockers in obstructive pulmonary disease: a randomised controlled trial.

In chronic obstructive pulmonary disease (COPD), the sympathetic nervous system, as well as the renin-angiotensin system, is activated with possible negative systemic effects on skeletal muscles. Angiotensin II type-1 receptor blockers inhibit the sympathetic and renin-angiotensin systems and might improve skeletal and respiratory muscle strength in patients in whom these systems are activated. The effects of the angiotensin receptor blocker irbesartan given over 4 months was evaluated in 60 patients with COPD and a forced expiratory volume in one second of <50% of the predicted value and without obvious cardiovascular disease that would necessitate the administration of an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Irbesartan was well tolerated, but did not exert a significant effect on the primary end-point maximum inspiratory pressure. Spirometric results were not affected, but total lung capacity was reduced. Irbesartan led to a significant decrease in haematocrit (46.4+/-3.6 to 43.9+/-4.3% versus 47.5+/-2.4 to 48.7+/-3.0% with placebo). In conclusion, respiratory muscle strength in chronic obstructive pulmonary disease patients was not influenced by angiotensin II receptor blockade. However, the changes in haematocrit and total lung capacity following irbesartan raise the possibility that well-known cardiovascular drugs can produce unanticipated beneficial effects in chronic obstructive pulmonary disease patients.

[Psychosocial factors in coronary heart disease -- scientific evidence and recommendations for clinical practice].

Psychosocial risk factors like low socio-economic status, lack of social support and social isolation, chronic work or family stress, as well as negative emotions, e. g. depression and hostility, contribute significantly to the development and adverse outcome of coronary heart disease (CHD). Negative effects of psychosocial risk factors are conveyed via behavioural pathways including unhealthy lifestyle, e. g. food choice, smoking, sedentary life, inadequate utilisation of medical resources, and psychobiological mechanisms like disturbed autonomic and hormonal regulation: all these factors contribute to metabolic dysfunction and inflammatory and haemostatic processes, which are directly involved in the pathogenesis of CHD. Interventions to improve pychosocial factors are available and have demonstrated positive effects on risk factors and - at least in part - on CHD morbidity and mortality. The prevention of CHD should therefore include screening for psychosocial risk factors and adequate interventions. Recommedations for the screening of risk factors, behavioural change and further management of psychosocial risk factors in clinical practice are pointed out.

[A set of questionnaires for the assessment (screening) of psychological disorders and social problems in cardiac rehabilitation patients].

A set of questionnaires for the assessment (screening) of psychological and social problems in cardiac rehabilitation patients is analyzed for its psychometric properties. The test battery had before been consented by a task force of the German Association for the Prevention and Rehabilitation of Cardiovascular Disease, DGPR. It integrates generally approved and well-tried assessments for depression/anxiety, social isolation (vocational) stress, and subjective vocational disability. The questionnaire was administered to a convenience sample of 426 patients undergoing inpatient cardiac rehabilitation. Results on the psychometric properties, a comparison of the cardiac sample to the general population, as well as distributions of quartile ranges are reported. Also, a preliminary appraisal of the need for further assessment or treatment is made. The results confirm that the short test battery is suited for assessing psychological and social problems in cardiac rehabilitation patients.

[Anxiety and depression in cardiology patients: how to diagnose, how to treat?].

IMPORTANCE: Anxiety and depression are frequent problems in patients with heart diseases. Prevalences vary between 15 and 50%, depending on diagnostic criteria as well as on sociodemographic and medical patient characteristics. During the last 10-15 years, a large number of studies have shown that anxiety and depression strongly affect overall well-being, cardiac and non-specific symptom reporting and overall quality of life. This leads to increased health care utilization, early retirement and imposes a financial burden on individuals and social security systems. In addition, anxious and especially depressed patients with heart disease tend to exhibit unhealthy illness behavior, low compliance and suboptimal risk factor control. Together with the known physiological effects of negative affect on cardiac autonomic balance, inflammation and platelet function, these behavioral mechanisms may lead to the frequently observed increase of cardiac event and mortality rates in depressed patients wit coronary artery disease. DIAGNOSIS: Despite their clinical relevance and unsatisfactory spontaneous remission rate, anxiety and depression still go unrecognized and undertreated in most cardiac patients. Case-identification can be improved by a graded approach. In the first step, symptoms of anxiety and depression should explicitly be asked for as part of a routine cardiological work-up. As an adjunct, validated self-rating questionnaires can be used for screening purposes. Patients screened positive should receive a thorough diagnostic interview and a criteria-based diagnosis. TREATMENT: Once a diagnosis has been obtained, several treatment options are available: In less severe cases (minor depression or adjustment disorders), supportive care by primary care physicians or cardiologists may be sufficient. Patients with major depression or panic disorder should receive structured psychotherapy and/or antidepressant medication. Exercise training can also improve symptoms of anxiety and depression. Although both psychotherapy and antidepressants, especially if integrated in a concept of comprehensive cardiac care, can be expected to result in marked subjective benefit for the majority of patients, the impact of these treatments on cardiac event and mortality rates still needs to be determined.

Depressed mood, physician-rated prognosis, and comorbidity as independent predictors of 1-year mortality in consecutive medical inpatients.

OBJECTIVE: To determine the independent effects of depressed mood and markers of medical disease severity on mortality in consecutive medical inpatients. METHODS: Consecutive general medical inpatients were asked to complete the Hospital Anxiety and Depression Scale (HADS) at admission. Prognostic indicators were obtained from patients' records and physicians' ratings. The study endpoint was mortality from all causes at 1 year. RESULTS: The baseline assessment was completed by 575 patients (87.7%). Survival data were available for 572 of these (86 deaths). HADS depression scores and several physical risk indicators predicted mortality. In multivariate analyses, physicians' rating of prognosis was the best predictor of mortality [adjusted odds ratio (OR) 3.6; 95% confidence interval (CI), 2.5--5.4]. Other independent predictors included a principal diagnosis of hemato-oncological disease, comorbidity scores, and HADS depression (adjusted OR 1.75; 95% CI, 1.10--2.79). CONCLUSION: Our data demonstrate an independent prognostic effect of depressed mood on mortality in general medical inpatients. Screening for depression may improve risk stratification in these patients over and above that obtained by routinely available physical parameters and physicians' clinical judgement.

Psychosocial factors have always been considered important causes of heart disease. Because of its extraordinary epidemiological and political relevance, coronary heart disease (CHD) has received Special scientific attention in this field. However, the abundance of literature dealing with its biological, psychological and social precursors is in sharp contrast with a lack of comprehensive modeis trying to integrate the results of different scientific traditions. This paper gives a brief overview of the present State of psychosocial research on etiological factors in CHD. Instead of solely relying on attempts to identify supposedly independent risk factors, it emphasizes the importance of dynamic biopsychosocial processes, which finally lead to manifest coronary disease. The paper outlines an approach which integrates clinical and empirical findings in a bio-psycho-sociodynamic model. This model is open to future extension. It may be helpful for better understanding individual patients as well as scientific findings. By providing hypotheses, which are suggested to go beyond the still predominating reductionistic, linear modeis, it may furthermore be a basis for future research in psychosocial cardiology.
