The cardiomyopathy of hypoparathyroidism. Another reversible form of heart muscle disease.

A patient with traumatic hypoparathyroidism had cardiomyopathy and congestive heart failure. The patient had no history of preexisting cardiac disease, alcohol abuse, hyperthyroidism, or hypothyroidism and improved greatly with treatment of hypoparathyroidism. We suggest that the cardiomyopathy seen in hypoparathyroidism. We suggest that the cardiomyopathy seen in hypoparathyroidism is due to many factors, but that hypocalcemia and possibly hypomagnesemia are especially important, and that correction of calcium and magnesium deficiencies may result in near-normal cardiac function.
