Abstract
- A 65-year-old woman presented with acute pulmonary edema, generalized tetany, and paresthesia. She had severe hypocalcemia, a low intact parathyroid hormone level, and her echocardiogram revealed left ventricular dysfunction. She had no history of heart failure or thyroid surgery. The heart failure improved after calcium replacement and conventional heart failure management. She was diagnosed with hypocalcemia-induced heart failure caused by idiopathic hypoparathyroidism. Despite the crucial role of calcium in myocardial contractility, hypocalcemia is rarely reported as a cause of heart failure. In conclusion, plasma calcium should be measured in the initial workup of all patients with heart failure, and corrected if hypocalcemia is seen. Idiopathic hypoparathyroidism is a rare cause of reversible heart failure that should be considered in the etiologic assessment.
