Trends in the incidence of cerebral hemorrhage and infarction in Japan were analyzed based on the 3 kinds of data obtained from death rate, autopsy case and our prospective study on CVD in a selected community, called Hisayama, Kyushu Island, Japan.
From the findings of mortality statistics it appears that cerebral hemorrhage has decreased slightly and, on the other hand, cerebral embolism and thrombosis has increased greatly for the recent 11 years.
Based on the main diagnosis of autopsy cases derived from various parts of this country, cerebral hemorrhage showed no definite change in annual incidence, while cerebral thrombosis had a steady increasing trend for the recent 5 years.
The prospective study on CVD in Hisayama showed a greatly decreasing trend in incidence of cerebral hemorrhage and a slightly increasing trend in incidence of cerebral thrombosis for the recent 3 years.
From these findings it can be supposed that there is some decreasing trend in cerebral hemorrhage and an apparent rising trend of cerebral thrombosis in Japan.
