Autopsy study of cerebrovascular disease in Japanese men who lived in Hiroshima, Japan and Honolulu, Hawaii (in Japanese and English)

Technical Report ·
OSTI ID:6056006

Evidence of cerebrovascular disease at autopsy was compared in two groups of men, 186 long time residents of Hiroshima, Japan and 253 men of Japanese ancestry long resident in Honolulu, hawaii. They were from 45 to 71 years of age at death. Atherosclerosis of the circle of Willis and its major branches, sclerosis of the intraparenchymal arteries and the frequency of cerebral hemorrhage and cerebral infarct were compared in the two populations. The Honolulu subjects had significantly more atherosclerosis of the circle of Willis, but less intraparenchymal artery sclerosis and less cerebral infarction. Cerebral hemorrhage was equally frequent in the two cities. It was concluded that cerebral infarction is more frequent in Japanese men in Hiroshima than Honolulu, and that men of Japanese ancestry in Honolulu are spared an appreciable risk of cerebral infarction through decreased frequenncy of intraparenchymal arterial sclerosis despite higher levels of atherosclerosis of large intracranial arteries.
