部分心性猝死者死后尸检时心脏没有发现明显病理学异常征象,过去均将其归属原因不明的猝死范畴。近年来研究显示,心肌连接蛋白43(connexin43,Cx43)表达对于心性猝死的诊断具有十分重要的意义。本文就Cx43结构、功能以及在心血管疾病发生发展中的作用与法医学意义作一综述。 Part of sudden cardiac death after death at necropsy did not find the pathology of the heart obvious signs of abnormalities, the past are attributable to unknown causes of sudden death category. In recent years, studies have shown that the expression of connexin43 (Cx43) is of great significance for the diagnosis of sudden cardiac death. This review summarizes the structure and function of Cx43 and its role in the development of cardiovascular diseases and forensic significance.
