Hypocalcemia is a relatively uncommon but reversible cause of congestive heart failure. A 39-year-old woman with hypocalcemia due to untreated hypoparathyroidism presented with congestive heart failure and a left ventricular ejection fraction of 25 percent. She had no evidence of underlying cardiac disease. The serum calcium level was normalized within one week, associated with complete clearing of the signs and symptoms of heart failure and a twofold increase to 50 percent in the ejection fraction. This is the first patient without underlying myocardial disease in whom significant improvement of left ventricular function has been quantitatively assessed prior to and following correction of hypocalcemia.
低钙血症是导致充血性心力衰竭相对少见但可逆转的原因。一名39岁因未治疗的甲状旁腺功能减退导致低钙血症的女性出现充血性心力衰竭，左心室射血分数为25%。她没有潜在心脏病的证据。血清钙水平在一周内恢复正常，同时心力衰竭的体征和症状完全消失，射血分数增加两倍至50%。这是首例无潜在心肌疾病的患者，在低钙血症纠正前后对左心室功能的显著改善进行了定量评估。
