The genesis of atherosclerosis in pediatric age-group.

The three forms of origin of the atherosclerotic plaque of adults, that is, the fatty streaks, gelatinous elevations, and microthrombi, all occur in arteries of normal infants and children. Some of these may become arrested or regress, but many progress to the prominent lesions that precipitate various clinical catastrophies. The aim of modern medicine is to modify or eliminate many of the factors known to advance the atherosclerotic process and thus decrease the incidence of this disease, which ranks highest on the list of causes of morbidity and mortality in the Western world. Of these factors, some may be controlled by dietary means (low salt; low total fat and cholesterol; appropriate ratios of saturated to mono- and polyunsaturated fatty acids; high content of complex carbohydrates and fiber); controlling hypertension, diabetes, and obesity; abstaining from cigarette smoking; and vigorous physical activities. Because patterns of life-style are determined in childhood and adolescence, and because it is only during that period of life that measures to prevent progression of atherosclerosis may be predictably effective, it becomes increasingly apparent that atherosclerosis is, indeed, a pediatric problem.
