近年来,随着人口老龄化及心血管疾病危险因素的增加,心血管疾病的患病率和病死率逐年上升,成为人类死亡的主要原因之一.甲状腺是人体重要的内分泌器官,其分泌的甲状腺激素作用于心血管系统的每一个组成部分.心血管系统是甲状腺激素作用的重要靶器官之一,甲状腺激素对心率、脉率、血液循环与心肌收缩均具有调节作用.现就甲状腺激素与心血管疾病关系的研究进展做一综述.“,”In recent years,with the aging of the population and the increase of cardiovascular risk factors,the morbidity and mortality of cardiovascular diseases have been increasing year by year,and become one of the major causes of human death.The thyroid gland is the largest endocrine gland in the body,and its secreted thyroid hormone regulates every component of the cardiovascular system.The cardiovas-cular system is one of the important target organs of thyroid hormone,and thyroid hormone on heartbeat,pulse,blood circulation,cardiac con-traction and oxygen consumption has a moderating role.This article reviews the current research progress of relationship between thyroid hor -mone and cardiovascular diseases.
