三、国际社会的防控情况从上世纪50年代一些发达国家就开始预防控制中风,做了五六十年工作。美国这些年中风的死亡率下降了60%,男性发病率下降了30%,女性发病率下降了18%。日本经过多年努力,脑血管病死亡率从第一位降到第三位,死亡率下降40%。在过去的40年中,发达国家发病率降低了42%,而发展中国家发生率增加了1倍以上,所以这个局势在发展中国家应特别引起重 III. Prevention and Control by the International Community Some developed countries started their prevention and control of strokes in the 1950s and have done 50 or 60 years of work. The U.S. death rate for stroke in these years has dropped by 60%, the incidence of males has dropped by 30%, and the incidence of females has dropped by 18%. After years of hard work in Japan, mortality from cerebrovascular diseases dropped from the top to the third place with a 40% drop in mortality. In the past 40 years, the incidence of the developed countries has been reduced by 42%, while the incidence of developing countries has more than doubled, so this situation should be especially detrimental in developing countries
