A rare cause of heart failure--primary hypoparathyroidism.

We report a patient who presented with congestive heart failure (ejection fraction 24.4%) and who had previous history of convulsions. Our investigations found him to be a case of primary hypoparathyroidism. He showed a dramatic response with the addition of calcium infusion therapy with almost full recovery of left ventricular function (67% ejection fraction after 16 days of the initial echo). We conclude that in a young patient a thorough investigation for heart failure is never complete without looking for endocrine and metabolic causes. The prognosis in these cases is much better, identification and treatment of the same will yield dramatic results.
