本研究确定了明尼苏达州罗切斯特市人群中1970年1月1日至1974年12月31日期间诊断为脑梗塞的所有人，并证实了先前报告的发病率持续下降。这一比率的下降速度一直在加快，妇女和年龄较大的年龄组的下降幅度相对较大。妇女的患病率有所下降，而男子的患病率没有下降。脑梗死的总体影响是使完全独立的人的比例从脑梗死前的57%下降到脑梗死后的16%。比较1945 ~ 1949年和1970 ~ 1974年两个五年期脑梗死患者的生存率，发现30天生存率仅增加2%; 5年生存率差异逐渐增加至16%。在这一人群中，脑梗死发病率下降和生存率提高的原因尚未确定，但有证据表明，在脑梗死发病前，社区对高血压的监测和治疗有所增加。
This study has identified all persons in the population of Rochester, Minnesota, who had a diagnosis of cerebral infarction during the period Jan. 1,1970, through Dec. 31,1974, and has confirmed the continuing decline in the incidence rate previously reported. The decline in the rate has been accelerating, with a relatively greater reduction occurring in women and in the more elderly age groups. There has been a decline in the prevalence rate in women which was not seen in men. The over-all impact of cerebral infarction was to reduce the proportion of those persons who were completely independent from 57% before cerebral infarction to 16% after infarction. Comparison of survival among patients with cerebral infarction occurring in the two quinquennia 1945-49 and 1970-74 showed only a 2% increased probability of survival at 30 days; the difference in survival increased progressively to 16% at 5 years. The reason for the declining incidence and increased survival in cerebral infarction in this population has not been established, but evidence of increased community surveillance and treatment of hypertension among persons before the onset of cerebral infarction is presented.
