A 60-year-old uremic patient treated with hemodialysis for 13 years developed acute hypotension during hemodialysis and overt heart failure subsequently in a period of relatively mild hypocalcemia after parathyroidectomy. Blood pressure during hemodialysis was maintained by continuous calcium infusion alone. Cardiomegaly was improved by normalization of serum calcium. The cardiac complication is considered to be exacerbation of the underlying myocardial dysfunction by the acute decline of serum calcium which might be a feature of the ‘hungry bone’ syndrome. Latent myocardial dysfunction might be exacerbated by only mild hypocalcemia after parathyroidectomy in long-term hemodialysis patients.
