Hypocalcemic heart failure in end-stage renal disease

A 37-year-old woman presented with hypocalcemic heart failure complicating end-stage renal disease. Heart failure persisted despite conventional therapy but improved after correction of hypocalcemia. Continuous monitoring of left ventricular function by radionuclide study during calcium replacement showed dramatic improvement. Our case showed that hypocalcemia could be a rare but reversible cause of frank heart failure in uremic patients.
