A visual planimetric study of atherosclerosis of the aorta and the coronary arteries was conducted in 1571 residents of the city of Ryazan and in 769 inhabitants of the Ryazan region dying in the age of 10 and 69 years, as well as in 627 normal individuals engaged in physical and intellectual work, living in rural and urban settlements, dying in the age of 40 to 69 years (data from Ryazan, Tallinn, Kharkov). A randomized study has demonstrated that urban population displays more distinct atherosclerotic changes in the examined vessels than the rural population displays more distinct atherosclerotic changes in the examined vessels than the rural population. The differences in the severity of coronary atherosclerosis were significant between the compared groups of normal individuals engaged in intellectual activities, and insignificant between the groups of those engaged in physical labour. The severity of aortic atherosclerosis did not show any statistically significant differences between the groups of normal individuals living in urban and rural areas.
对梁赞市的1571名居民、梁赞地区769名年龄在10至69岁死亡的居民，以及627名从事体力和脑力劳动、生活在农村和城市定居点、年龄在40至69岁死亡的正常个体，进行了主动脉和冠状动脉动脉粥样硬化的视觉平面测量研究（数据来自梁赞、塔林、哈尔科夫）。一项随机研究表明，城市人口在所检查血管中显示出比农村人口更明显的动脉粥样硬化变化。在从事脑力活动的正常个体比较组之间，冠状动脉粥样硬化严重程度的差异显著，而在从事体力劳动的组之间差异不显著。城市和农村地区正常个体组之间，主动脉粥样硬化的严重程度没有显示出任何统计学上的显著差异。
