Introduction.Cardiomyopathy secondary to severe hypocalcaemia can lead to death when misdiagnosed. However, it can respond favorably to calcium and vitamin D as in this observation.\r\nCase report. SB, 50 years old, was hospitalized for heart failure. He was operated on for cataracts and treated for epilepsy, but was not known as having heart problems.\r\nClinical examination revealed global heart failure. Chest x ray showed cardiomegaly with bilateral pleural effusion. Echocardiography demonstrated myocardium dilatation with an\r\nimpaired systolic function (ejection fraction = 38%, N≥ 60). Heart screening did not find any cause, but laboratory investigation diagnosed severe hypocalcemia (mean value: 26mg/L (N=80-105) or 0.65 mmol/L), high phosphorus (61.5mg/L, N=25-45), and low parathormone (6.51 pg/mL, N=15-65 pg/mL). Corrected calcium according to protidemia\r\nwas 0.69 mmol/L. Magnesium was normal. Brain CT scan showed bilateral and symmetrical calcifications of basal ganglia\r\narguing for Fahr?s syndrome. After calcium (1g) and vitamin D (2, then 3 μg/day) during one week, cardiac abnormalities improved promptly. Three months later seizures disappeared totally after stopping anti epileptic drugs.\r\nConclusion.The fast reversibility of heart failure and seizures under calcium suggests observed symptoms were due to hypocalcaemia, seemingly installed on a previously normal heart function. So, calcium assessment should be checked systematically in heart insufficiency.
