title: [Ischemic preconditioning: concept of endogenous myocardial protection].
abstract: Preconditioning is a temporary tolerance to ischaemia acquired by the myocardium after a short period of ischaemia. It results in the limitation of the infarct size induced by prolonged coronary occlusion. The mechanism of this cytoprotection remains poorly understood. The A1 adenosine receptors, the ATP-sensitive potassium channels and protein-kinase C seem to play prominent roles. The effects of preconditioning on the complications of ischaemia/reperfusion such as myocardial stunning, ventricular arrhythmias or decreased coronary reserve are not well known. Several studies suggest that the cytoprotection resulting from preconditioning could be applied to human myocardium and constitute a preventive anti-ischaemic therapy during coronary angioplasty, cardiac surgery or the conservation of transplant grafts.
