A brief period of ischaemia is known to induce a prolonged period of reversible myocardial dysfunction despite normalized electrocardiogram and absence of histological signs of necrosis. This was first described by Heyndrickx and co-workers [1] who found that myocardial function was depressed for several hours following a 15-min period of coronary artery occlusion in dogs. Braunwald and Kloner [2] subsequently named this phenomenon myocardial stunning. Although the exact mechanism underlying myocardial stunning is not fully understood, results from several studies indicate that it can be mediated by increased myocyte calcium levels and oxygen-derived free radicals during ischaemia and the initial part of
