Endogenous Mechanisms of Cardioprotection

Show Summary Details

Preview

• Ischaemic preconditioning is the most powerful endogenous mechanism for limiting myocardial infarct size in the experimental setting. Its clinical application is limited to scenarios in which the index episode of ischaemia and reperfusion can be anticipated such as in the setting of cardiac surgery • Ischaemic postconditioning represents an endogenous cardioprotective strategy which is applied at the onset of myocardial reperfusion, thereby allowing its use as an adjunct to reperfusion in patients presenting with an acute myocardial infarction • Both ischaemic preconditioning and postconditioning recruit a common signal transduction pathway at the time of myocardial reperfusion, which can be targeted by pharmacological agents administered as adjuncts to reperfusion.
