慢性心力衰竭(CHF)是各种心脏结构或功能性疾病导致心排出量不足,是所有心脏疾病发展的终末阶段,慢性心力衰竭病死率极高,临床救治难度大。同时慢性心力衰竭的患者也伴有一系列神经、内分泌系统的改变。近年来随着对慢性心力衰竭发病机制研究的进一步深入,发现其病理过程与甲状腺素的代谢异常具有相关性~([1]),并且目前的研究结果表明,应用小剂量甲状腺素治疗慢性心力衰竭时有利于患者心功能的好转~([2])。我们于2015年9月 Chronic heart failure (CHF) is a type of cardiac structure or functional disease leading to inadequate cardiac output, is the terminal stage of development of all heart diseases, chronic heart failure mortality is extremely high, clinical treatment is difficult. Patients with chronic heart failure are also accompanied by a series of changes in the nervous and endocrine systems. In recent years, with the further study of the pathogenesis of chronic heart failure, and found that the pathological process and thyroid hormone metabolism is related to ([1]), and the current results show that the application of small doses of thyroxine in the treatment of chronic heart failure Failure is conducive to the improvement of cardiac function in patients with ~ ([2]).
