自从Morgagni评论发生家族性中风问题以来,一些研究者一直尝试确定心血管发病的因素是否是遗传的。Stocks指出,同卵双生比之异卵双生的血压水平之间具有较强的相关性。在所有这些研究中,要从共有的环境作用中分析出其共同的基因效应是困难的。理论上研究丈夫与妻子之间的血压的相关,可以回答这个问题。因为他们共处同一环境,而有不同的遗传物质。夫妇间的相关系数,
Since the Morgagni commentary on the issue of familial stroke, some researchers have been trying to determine whether the cardiovascular risk factors are inherited. Stocks pointed out that the same twins than the fraternal twins have a strong correlation between blood pressure levels. In all these studies, it is difficult to analyze their common genetic effects from the shared environmental effects. Theoretically studying the correlation between husband and wife’s blood pressure can answer this question. Because they live in the same environment, they have different genetic material. The correlation coefficient between couples,
