有两个家族,其成员中55岁以前患早期心脏病的是没患此病的5～10倍,其中四分之三可能与遗传有关。这些数据来自美国最大的一次心脏病遗传研究的调查结果。在这次调查中Utah大学的Roge R.Williams及其助手收集分析了Utab州94000多人的健康史。最近,Williams将其研究结果在美国心脏协会科学家论坛进行了讨论。与此同时还进行了其它的工作,比如,Framinghan,Ma-ss。居民的情况也正在调查,已经建立了可靠的家庭健康史档案。这项工作还是刚刚开始,只是统计了一两代人,因此还没有确定出量的关系。另据对Framinghan居民进行研 Two families whose members have an early heart disease before age 55 do not have 5 to 10 times the disease, of which three-quarters may be genetically related. These data come from the findings of a survey of the largest genetic study of heart disease in the United States. In this survey, Roger R. Williams and his aides at Utah University collected and analyzed the health history of more than 94,000 people in Utab State. Recently, Williams discussed the results of his research at the American Heart Association Scientists Forum. At the same time, other work was done, for example, Framinghan, Ma-ss. The situation of residents is also being investigated and a reliable family health history file has been established. This work is still just beginning, but statistics of a generation or two, so there is no quantitative relationship. According to another study of Framinghan residents
