title: [Prevention of pathological aging. The arterial hypertension example].
abstract: Studies conducted during the last decade have made it increasingly easier to distinguish between normal and pathological ageing. Previous studies on general populations had established a dogma: most of the major body functions, such as cardiac output, glomerular clearance, muscular strength, visual acuity and so forth, were supposed to decline with age. However, in recent studies on the effects of age on cardiac output all subjects with heart disease were excluded and as a result the negative correlation found between cardiac output and age disappeared, which shows that a phenomenon attributed to ageing was in fact caused by disease. This does not mean that there is no such thing as fundamental ageing, and indeed the mechanisms that maintain cardiac output are different in young and elderly subjects. These data are of more than theoretical interest, since it may be presumed that prevention, the instruments of which are already available in some fields, will modify the profile of ageing. The risk of arterial hypertension is not restricted to the classical cardiovascular diseases: it extends to other diseases, such as vascular dementia, which are potent factors of pathological ageing. Most of the controlled trials carried out in arterial hypertension have demonstrated that treating certain types of hypertension significantly reduces the morbidity and/or mortality of cardiovascular diseases. The specific properties of new antihypertensive drugs, such as angiotensin-converting enzyme inhibitors, open stimulating vistas on arterial ageing.
