Brief periods of ischaemia, are known to induce a reversible deficit in myocardial function despite the maintenance of histological and metabolic integrity, a phenomenon initially described by Heyndrickx et al. in 1975, and called stunning several years after [1]. In that first study it was reported that several hours were required for complete recovery of regional contractility following a 5 min occlusion of the left anterior descending coronary artery in conscious dogs and up to 24 h were needed for complete recovery following a 15 min occlusion [1]. Therefore, myocardial stunning is considered to represent reversible injury contrasting the irreversible injury of myocardial infarction. The phenomenon has been described in every species studied so far, does occur in several clinical settings and likely plays an important role in the morbidity of patients with coronary artery disease [2]. Although the principal cause of the reversible contractile dysfunction is
