Based on the working hypothesis that coronary atherosclerosis begins in childhood, a histologic study was carried out on the subepicardial coronary arterial tree of 100 young persons (1-20 years), who had died from causes unrelated to the cardiovascular system. These subjects were natives of a well-defined geographic area in northern Italy, namely the region of Veneto. Intimal proliferations (musculo-elastic and fibro-elastic layers) were observed in 95.3% of the coronary arterial segments in the age group between one and five years. The more distal the coronary segments examined, the lesser was the intimal thickening. Raised mature fibrous plaques were detected in 23 segments from 15 patients (2 from subjects aged between six and 10 years; 4 between 11 and 15 years, and 9 between 16 and 20 years). Single vessel disease was present in 9, double vessel disease in 4 and triple vessel disease in 2 cases. The site most involved by plaques was the proximal part of the left anterior descending coronary artery. Only one plaque was of sufficient dimensions to be considered stenotic (50% luminal reduction). Plaques were rarely sudanophilic, and all seemed to arise in relation to previous intimal thickening. No qualitative nor quantitative sexual differences were observed. These data give rise to much concern, and one consistent with a recently observed occurrence of sudden coronary death in young people from the same geographic area.
