A man presented with an exacerbation of heart failure following coronary artery bypass grafting. He was found to be severely hypocalcaemic secondary to a combination of decreased parathyroid reserve and severe vitamin D deficiency. On treatment of his hypocalcaemia, all symptoms resolved. This case highlights the importance of recognising that metabolic derangement can affect cardiac function.
