title: [Classical cardiovascular risk factors: predictive value and treatment of the elderly. The rocky road to evidence-based medicine].
abstract: Coronary heart disease and cerebrovascular disease are still the most common causes of death in Western countries. A number of risk factors have been identified in young and middle-aged adults, such as dyslipidemia, hypertension and diabetes. Their prevalence and importance, however, are less clear in the elderly. In terms of dyslipedemia it is questionable whether hypercholesterolemia is a definite risk factor. On the other hand, mortality can be reduced by lowering LDL cholesterol, but the benefit in the oldest old is not yet known. Systolic blood pressure rises with age and is discussed controversely as a potential risk factor in the elderly. Some large trials could show a clear relationship between high blood pressure while others did not see any association. Similar to the treatment of hypercholesterolemia, antihypertensive drugs showed beneficial effects in elderly people until the age of 80. But the treatment of the oldest old cannot be recommended in general. Diabetes and impaired glucose tolerance are some of the most common diseases in elderly people. They are considered to be an important risk factor until the age of 75. Their role in the oldest old is still under debate. Until now, we do not know anything about possible treatment effects because of the lack of controlled trials. Elderly people seem to have a risk profile different from younger people; especially in extreme ages the predictive role of classical risk factors is unclear. On the other hand, drug treatment could reduce mortality and morbidity in patients with hypercholesterolemia or hypertension. There are no studies which investigated the effects of blood glucose control in the elderly. The collection of sufficient data is a geriatric challange in order to decide whether treatment is useful or not.
