It was described in the early years of open heart surgery with cardiopulmonary bypass.<\/em><\/p>\n<p>Global ischemic contracture of the heart resulting in a firm myocardium and loss of intracavitary volume is termed stone heart syndrome.<sup>1<\/sup> Physiologists have long described cardiac arrest in systole with calcium which is also considered as the danger of intravenous administration of calcium in the presence of digoxin toxicity (digitoxicity). Stone heart syndrome was described as a complication of cardiopulmonary bypass in the early years of cardiac surgery as an inability to successful resuscitation.<sup>2<\/sup> This complication of cardiopulmonary bypass has largely been\u00a0prevented in later years with good cardioplegia.<\/p>\n<p><span style=\"color: #0000ff;\"><strong>Prevention of stone heart syndrome<\/strong><\/span><\/p>\n<p>In experimental animals, beta blockade has been shown to delay myocardial ischemic contracture.<sup>3<\/sup>\u00a0Moderate hypothermia was also shown to be effective in preventing ischemic contracture in the same study. A recent cardiac magnetic resonance imaging based study in porcine model has shown that even mild hypothermia is useful in prevention of the dreaded stone heart syndrome of ischemic cardiac contracture.<sup>4<\/sup> In this context, hypothermia can be classified into mild (32\u00b0C &#8211; 34\u00b0C),\u00a0moderate (28\u00b0C-32\u00b0C), deep \u00a0(28\u00b0C-15\u00b0C), and profound (&lt; 15\u00b0C). Successful resuscitation after ice water drowning gives a good clinical example of hypothermia protecting against stone heart. A two and a half year old girl had good neurological recovery even after 66 minutes of submersion in cold water with core temperature dropping to\u00a019\u00b0C.<sup>5<\/sup> In this remarkable event, cardiopulmonary resuscitation was maintained for over two hours before extracorporeal rewarming.<\/p>\n<p><span style=\"color: #0000ff;\"><strong>Genesis of ischemic contracture in stone heart syndrome<\/strong><\/span><\/p>\n<p>31P based nuclear magnetic resonance spectroscopy imaging has documented that ischemic contracture coincides with the stopping of anaerobic glycolysis in a murine model.<sup>6<\/sup>\u00a0It is known that ischemic contracture is the result of formation of rigor bond when the adenosine triphosphate (ATP) levels are low in the myofibrils. Stoppage of glycolysis naturally leads to depletion of ATP levels and ischemic contracture, causing the stone heart syndrome.<\/p>\n<p><span style=\"color: #0000ff;\"><strong>References<\/strong><\/span><\/p>\n<ol>\n<li>Cooley DA, Reul GJ, Wukasch DC.
