Hypocalcemia is one of the rarest causes of reversible cardiomyopathy. Patients with refractory heart failure need to be explored for hypocalcemia and need prompt correction.
Abstract: Hypocalcemia is a rare cause of reversible dilated cardiomyopathy. Correction of calcium is crucial to recover left ventricular function and structure. We presented the case of a 55-year-old female who was admitted to the hospital with refractory heart failure due to hypocalcemia induced by primary hypoparathyroidism and complicated by vitamin D deficiency. The patient's cardiac symptoms improved dramatically upon correction of hypocalcemia, and vitamin D. Therefore, the key clinical message of this case report is, that hypocalcemia, although rare, should be considered as one of the differential diagnoses when heart failure is refractory and early diagnosis and treatment is necessary as it is the cause of reversible cardiomyopathy and could reduce morbidity and mortality.
