title: Natural history of aortic and coronary atherosclerosis in Tokyo.
abstract: The natural history of atherosclerosis in Tokyo was explored in 1,206 unselected consecutive hospital and forensic medicine autopsies performed on deceased persons of both sexes aged 0 to 89 yr. The extent of intimal atherosclerotic lesions in the aorta and coronary arteries was estimated visually after staining with Sudan IV and recorded as the percentage of intima with fatty streaks (FS) and raised lesions (RL). The extent of atherosclerosis by sex and age was compared in two sources of subjects and various broad disease categories associated with the terminal event causing death. Comparisons of hospital cases with forensic medicine cases, by sex, over five arterial segments and nine 10-yr age groups, did not show significant differences in the extent of atherosclerosis between the two sources of cases. However, RL at all age groups over 40 yr in general showed a tendency to be slightly more extensive in the hospital cases. As is commonly reported for certain other population groups, our results showed more extensive atherosclerosis in Japanese men than in Japanese women. The comparisons of the extent of atherosclerosis among five broad disease categories causing death--coronary heart disease (CHD), cerebrovascular disease (CVD), cases with evidence of both CHD and CVD (OVL), cases with CHD-related diseases such as diabetes and hypertension (CHD-rel), and all other diseases, accidents, homicides, and suicides (Basal)--showed more extensive atherosclerosis among CHD and OVL cases when compared with the basal group as control reference.(ABSTRACT TRUNCATED AT 250 WORDS)
