两例心肥大和充血性心力衰竭的病人被发现有未被诊断的甲状旁腺功能减退症所引起的显著低血钙症.心力衰竭对洋地黄制剂和利尿剂无效,但对使血钙恢复正常的特异性治疗效果明显.对低血钙症引起充血性心力衰竭的机理加以讨论.可逆性心肌病可能由低血钙症引起必须引起重视,尤其在病人对通常治疗心力衰竭的措施无效时.过去十年来,钙在心肌的一切工作中起了兴奋一收缩联结的中心作用已被证实.在临床和实验室心力衰竭中,钙离子的释放或结合有缺陷亦已被发现.虽然在动物实验中,低血钙症可引起心功能不全,但在临床实践中,低血钙症引起充血性心力衰竭非常罕见,仅有个别病例报道,且多数在儿科医学文献中.我们描述2例严重充血性心力衰竭患者,1例为儿童,另1例为成人,伴有因甲状旁腺功能减退症而引起的严重而持久的低血钙症.该2例对通常用以治疗心力衰竭的洋地黄和利尿剂无效,而对单独应用钙剂反应十分良好,最后导致完全恢复,从而证实该2例的心肌功能不全系由钙缺乏所引起.
Two patients with congestive heart failure and congestive heart failure were found to have significant hypocalcemia due to an undiagnosed hypoparathyroidism.Heart failure is not effective against digitalis and diuretics, The normal, specific treatment is evident, and the mechanism of hypocalcemia-induced congestive heart failure is discussed.Reversible cardiomyopathy may be caused by hypocalcemia, which must be emphasized, especially if the patient is ineffective in the usual treatment of heart failure The central role that calcium has played in excitability-systolic coupling in all cardiac work over the past decade has been demonstrated, and calcium or calcium release defects have also been found in clinical and laboratory heart failure, Hypocalcemia can cause cardiac insufficiency in experiments, but in clinical practice hypocalcemia causes congestive heart failure is very rare, only a few cases reported, and most of the pediatric medical literature we describe 2 cases of severe One patient was congestive heart failure, one was an adult and the other was accompanied by severe and persistent hypocalcemia due to hypoparathyroidism. The two patients were usually treated with Heart failure, digitalis and diuretics invalid, while the reaction of calcium alone is very good, leading to complete recovery, confirming that the two cases of myocardial dysfunction caused by a calcium deficiency Department.
