| Abstract: | A gross morphometric study of coronary atherosclerosis was performed in 554 native males aged 20-59 years and 142 migrant males of the same age from Andizhan according to the WHO Expert Programme (Bull, WHO, 1976, vol. 53, p. 485). The migrants over 40 years displayed a greater extent of atherosclerosis (except lipid streaks) than did the natives; but there were small differences between the comparable groups of young persons under 40 years. A histometric study of the coronary arteries was made in 81 apparently healthy males indicated that fine-dropped (mainly intracellular) lipid deposits were more common in the natives, mixed (fine- and coarse-dropped) and coarse-dropped lipid deposits occurring with cell breakdown were seen in the migrants. The thickness of atherosclerotic lesions in the coronary arteries was greater in the migrants. Varying degrees of coronary intimal hyperplasia were found in individuals from the comparable ethnic groups. The hyperplasia was more profound in the migrants. There was a direct relationship between its degree and the development of atherosclerotic lesions. |
