[Age-related characteristics of the normal blood content of lipids and lipoproteins and in arterial hypertension].

The quantity of low and very low density lipoproteins and the total cholesterine is increased in the blood of healthy subjects with advanced age (60-74) as compared with young subjects (20-30). The incidence of hyperlipoproteinemias is increased and cholesterine content is reduced in the composition of high density lipoproteins. In old age (75-89) those discrepancies are less manifested as compared with the young. Hyperlipoproteinemias (IIa, IIb, II and IV types) are more frequent in hypertonic disease, mainly in young patients and patients with advanced age. The content of lipids and lipoproteins in blood is increased in atherosclerotic systolic hypertension; hyperlipoproteinemias (mainly IV type) are found more often in old age.
