遗传因素在心肌梗塞和血管性疾病危险因素中起着重要作用,但遗传对脑卒中的作用极少有研究。长期以来,孪生研究已被用来评价某一特征或疾病的遗传性。这些研究对了解复杂特征,例如心血管病危险因素、糖尿病、高血压病等的遗传性是有益的,为目前心血管病的研究进入分子生物学水平铺平了道路。作者将这项技术应用于脑血管病的研究。 Genetic factors play an important role in the risk of myocardial infarction and vascular disease, but there is little research on the role of genetics in stroke. For a long time, twin studies have been used to evaluate the inheritance of a particular trait or disease. These studies are beneficial for understanding the complex features, such as the genetic risk of cardiovascular risk factors, diabetes and hypertension, and paving the way for the current research on cardiovascular diseases to enter molecular biology. The authors apply this technique to the study of cerebrovascular disease.
