All doctors, and most of their patients, are familiar with the consequences of stroke. In 1985 more than 70,000 men and women over the age of 65 died after a stroke and only one third of the survivors of stroke made a good recovery. It is thus a major source of chronic disability, placing a very heavy burden on patients' relatives and friends and consuming a great deal of NHS resources. The purpose of this Report is to set out guidelines for the clinical, radiological and pathological assessment of stroke, to suggest how to care for and rehabilitate patients who have suffered a stroke, and to evaluate and recommend measures for its prevention. The Report emphasises the need to use standard terms for the clinical description and classification of stroke, and the assessment of degrees of disability. It traces its changing epidemiology in the UK and in other countries and assesses the significance of putative risk factors such as hypertension, smoking, obesity, alcohol, diabetes, serum cholesterol, oral contraceptives and ischaemic heart disease. It sets out the indications for admitting patients to hospital and how they should be investigated, including the value of CT scanning at different intervals after the stroke has occurred. The Report describes the organisational aspects of the care of stroke patients during the acute phase, in the early recovery phase and in the longer term rehabilitation.(ABSTRACT TRUNCATED AT 250 WORDS)

Ever since the concept of value for money in health care was introduced into the NHS, economic terms and jargon have become part of our everyday lives--but do we understand what the different types of economic evaluation all mean, particularly those that sound similar to the uninitiated? This article introduces readers to the purpose of economic evaluation, and briefly explains the differences between cost-minimisation analysis (used when the outcomes of the procedures being compared are the same); cost-effectiveness analysis (used when the outcomes may vary, but can be expressed in common natural units, such as mm Hg for treatments of hypertension); cost-utility analysis (used when outcomes do vary--for example, quality of life scales); and cost-benefit analysis (used when a monetary value is being placed on services received). Further articles will deal with each one in more detail.

Coronary artery disease (CAD) has a strong genetic component, but is also greatly influenced by environmental factors such as diet and smoking, and disorders such as diabetes mellitus and hypertension. This interaction makes prediction of CAD risk generally difficult. However, in familial hypercholesterolaemia (FH), risk of early CAD is considerably increased by the mutation of a single gene, and genetic testing may be appropriate. We summarize current knowledge concerning DNA-based tests in the identification and management of FH, and propose specific recommendations for genetic testing and further research. The major value of DNA tests for FH is in genetic tracing programs to identify and treat affected individuals. DNA testing is appropriate for: (a) diagnosis of FH when physical signs or family history are equivocal or absent (important given the increased risk of CAD associated with FH compared to other hypercholesterolaemias); (b) detection of a mutation causing FH in immediate family members (particularly children) where there is a family history of premature CAD. A positive DNA-based test for a mutation is especially useful in children, in whom plasma lipid levels may not be diagnostic. Current clinical practice is to test relatives for raised cholesterol. Testing for mutation carriers in distant relatives, although feasible, is not currently recommended. Research projects should now be started to address two issues: (i) whether genetic tests for FH better predict clinical outcome than does measurement of plasma lipid levels; (ii) whether genetic testing for FH confers overall benefit both to the patient and their relatives, and to the NHS. Answers to these questions will guide the subsequent development and implementation of genetic tests for CAD risk in general, if and when the considerably more complex genetic causes of CAD are identified.

Reports from several countries indicate that women are disadvantaged in the treatment of coronary heart disease. The aim of the present review is to examine--on the basis of current population-based data (National Health Survey [NHS], hospital diagnosis registry, mortality rates)--whether in the Federal Republic of Germany more recently a change in favor of women could be established. According to NHS results prevalence rates of hypertension, overweight, and smoking in men exceed those of women, whereas hypercholesterolaemia is equally prevalent in both sexes. From 1984/85 to 1990/91 the NHS revealed a marked decline of smoking in men, and a parallel increase in women. The prevalence of chest pain shows no gender difference, but chest pain in men is more predictive for coronary artery disease. In acute myocardial infarction [AMI] thrombolysis and PTCA are applied with equal frequency; the average length of stay in hospital is greater for women. Coronary bypass surgery and rehabilitation in hospitals are less frequently applied in women. Little is known about gender differences in psychosocial adaptation after AMI. AMI mortality rates in all age groups are lower in women, and their mean age of death is higher. However, the decline of AMI mortality since 1980 was less pronounced in women compared to men.

Sildenafil is the first of a series of orally active treatments for MED which has resulted in unprecedented demand for treatment and potentially high cost to the NHS. Further oral therapies are likely to follow in the next year or so. In clinical trials, sildenafil produced an erection (sufficient to achieve intercourse) lasting up to 4 h on around 70% of occasions. This was reduced to 50% in 'high-risk' groups (e.g. diabetics) and a placebo response in as many as 10-20% has been reported. Whether or not sildenafil should be prescribed at NHS expense has been more a matter for political, than clinical, debate. A clearer picture is now emerging with treatment available to those considered the 'most deserving' cases. The bigger picture is of impotence in large numbers of men with hypertension who are on antihypertensive therapy and have obvious small vessel disease. One option is to consign sildenafil to Schedule 10 (Black List) so that it is only available on private prescription. This would allay fears of the cost of treatment for those merely seeking to 'boost' already adequate sexual performance.

Stroke is a preventable disease and there are several interventions that might have an important role in reducing the burden of disease. Economic appraisal of these different interventions is essential as resources are scarce and it is logical to attempt to obtain the greatest reduction in disease for the lowest cost. Anticoagulation for non-rheumatic atrial fibrillation is highly effective, but is expensive and cost-effectiveness analyses show that use of aspirin alone would prevent almost as many strokes at much lower cost. Antiplatelet drugs are both effective and inexpensive and their use in secondary prevention would potentially save the NHS about 900 Pounds per life year gained. Carotid endarterectomy and the associated screening costs are poor value for money but recent attempts to use predictive models to determine which patients will benefit from surgery may improve its cost-effectiveness. Current evidence is dominated by pharmacological interventions and much less good evidence is available for life-style modifications such as dietary change and physical exercise. Modification of major cardiovascular risk factors (blood cholesterol, high blood pressure and smoking) is very cost-effective but needs to be better targeted if potential health gain is to be realised.

We have reported that high job strain was associated with a significantly higher diastolic blood pressure (DBP) of 4.5 mm Hg during the working hours, irrespective of BP reactivity to a stress test. We report the final results of the first 5-year follow-up study, which aimed to assess the respective influences of perception of professional strain and cardiovascular reactivity to a mental stress test on BP. A cohort of 292 healthy subjects (mean+/-SEM age, 38+/-1 years) was followed up for progression to hypertension outcome, which was defined as an increase in systolic blood pressure (SBP) or DBP >7 mm Hg or a DBP >95 mm Hg during follow-up. None of the subjects was lost to follow-up, and 209 subjects completed the study. The high-strain (HS) group, representing 20.9% of the subjects, was compared with the remaining subjects (non-high-strain [NHS]). Similarly, the subjects with the highest BP stress reactivity (HR; 20.9% of subjects) were compared with the remaining subjects (NHR). Progression to hypertension was reached by 93 subjects (31.8%). Kaplan-Meier survival estimates revealed that neither HS nor HR increased the incidence of progression to hypertension. End-of-follow-up 24-hour ambulatory BPs that were similar in HS and NHS (120+/-2 vs 120+/-1 mm Hg, respectively) and in HR and NHR (122+/-2 vs 120+/-1 mm Hg, respectively) confirmed our findings. Age, alcohol, salt diet, body mass index, and occupation did not interfere with our results. In conclusion, cardiovascular HR and HS do not appear to be major risk markers for future high BP in healthy, young adults.

High job strain has been reported to be associated with higher blood pressure. Job strain could lead to hypertension if individual perception of stress or cardiovascular reactivity to stress are high. We report the results of the first five-year follow up study, which aimed to assess the respective influences of perception of professional strain and cardiovascular reactivity to a mental stress test on BP. A cohort of 292 healthy subjects (mean +/- SEM, 38 +/- 1 years) was followed for progression to hypertension outcome which was defined as an increase in SBP or DBP higher than 7 mmHg or a DBP higher than 95 mmHg during the follow-up. The high strain (HS) group representing 20.9% of the subjects was compared with the remaining subjects (NHS). Similarly the 20.9% subjects with the highest BP stress reactivity (HR) were compared with the remaining subjects (NHR). The Kaplan-Meier survival estimates revealed that neither high job strain, nor high stress reactivity, increased incidence of progression to hypertension. Age, alcohol, salt diet, BMI, and occupation did not interfere with our results. In conclusion, high stress cardiovascular reactivity and high job strain do not appear to be major risk markers for future high BP in healthy young adults. Stress could be associated with high BP at a short term and could explain high blood pressure in a long run only in stress-sensible subjects.

Population ageing, escalating costs in pensions, health-care and long-term care have prompted a new policy agenda for active ageing and quality of life in old age across the European Union and other developed countries. In England, the National Service Framework for Older People (NSF OP) explicitly demands for the first time that the NHS and local authorities, in partnership, agree programmes to promote health ageing and to prevent disease in older people. These programmes are expected to improve access for older people to mainstream health promotion services and also to develop multiagency initiatives to promote health, independence and well-being in old age. This paper describes the evaluation of one interagency project team established to test out mechanisms for addressing health promotion for older people through primary care. A mixed methodology was used to understand the processes of service development, the impact of the team's intervention, and the primary and secondary outcomes for older people. The project demonstrated that multi-agency partnerships have the potential to improve the quality of the lives of older people deemed 'at risk' by their general practitioners, particularly through income generation but also in the identification of medical problems such as unrecognised hypertension, hearing loss and visual loss. It also offered some key learning points for other multi-agency groups developing similar services.

Emerging evidence suggests an inverse relation between vitamin D and blood pressure. We examined the independent association between intake of vitamin D and the risk of incident hypertension among participants of 3 large and independent prospective cohorts: Nurses Health Study I (NHS I; n=77,436), NHS II (n=93,803), and Health Professionals' Follow-up Study (HPFS; n=38,074). Relative risks and 95% confidence intervals for incident hypertension were computed according to quintiles of vitamin D intake using Cox proportional hazards regression and adjusted for relevant covariates. Each cohort was followed for > or =8 years. Vitamin D intake was not associated with the risk of developing hypertension. The multivariable relative risk estimates for the highest compared with lowest quintile of intake were 0.98 (0.93 to 1.04) in NHS I, 1.13 (0.99 to 1.29) in NHS II, and 1.03 (0.93 to 1.15) in HPFS. When we compared participants who consumed > or =1600 to <400 IU per day and those who consumed > or =1000 to <200 IU per day, no association was found. We conclude that higher intake of vitamin D is not associated with a lower risk of incident hypertension.
