RESUMO
Aging, hypertension and diabetes are the three major risk factors that predispose to atherosclerosis. The authors tried to elucidate the terminal clinical pictures of these three major factors in terms of the mechanocardiographical findings and blood chemistry parameters related to nutrition (NBC), which are considered to be useful for the determination of the signifying or trigger risk factors of impending cerebral attacks.<BR>As the terminal clinical pictures of each of these three major factors, increase in peripheral resistance and inclination to low cardiac functions were observed. And in the process of transition to terminal pictures, increase in serum lipids and decrease in albumin, accordingly, increase in lipid/protein ratio were observed. Increase in such ratio is considered to be important for the development of atherosclerosis and low cardiac function.<BR>In rural areas mortality rate of strokes is markedly higher than in urban areas. Such high stroke incidence may be ascribed to the marked increase in cardiac impairments, as compared with the urban hypertensives of the same age groups. The factor of cardiac impairments may be ascribable to different nutritional conditions.<BR>Therefore, for the purpose of prevention against predisposition to strokes, early detection, as well as treatment, of cardiac impairments of elderly people, hypertensives and diabetics are deemed necessary. In this connection, improvement of nutritional conditions is very important.
