Postconditioning the human heart
Acute myocardial infarction is a frequent and disabling disease. Ischemic postconditioning, consisting of repeated brief cycles of ischemia-reperfusion performed immediately after reperfusion following a prolonged ischemic insult, dramatically reduces infarct size in experimental models. A recent clinical study demonstrated that repeated brief episodes of inflation-deflation of the angioplasty ...
متن کاملPostconditioning the human heart.
BACKGROUND In animal models, brief periods of ischemia performed just at the time of reperfusion can reduce infarct size, a phenomenon called postconditioning. In this prospective, randomized, controlled, multicenter study, we investigated whether postconditioning may protect the human heart during coronary angioplasty for acute myocardial infarction. METHODS AND RESULTS Thirty patients, subm...
متن کاملPostconditioning the human heart with adenosine in heart valve replacement surgery.
BACKGROUND The effect of adenosine postconditioning on myocardial protection in cardiac surgery remains uncertain. The present study evaluated the safety, feasibility, and beneficial effect of adenosine postconditioning as an adjunct to predominantly used cold-blood cardioplegic myocardial protection method in the setting of heart valve replacement operations. METHODS Sixty patients with rheu...
متن کاملHeart Failure Delayed Postconditioning in the Mouse Heart In Vivo
Background—Reperfusion during acute myocardial infarction remains the best treatment for reducing infarct size. Postconditioning, applied at the onset of reperfusion, reduces myocardial infarction both in animals and humans. The objective of this study was to identify the time delay to apply postconditioning at reperfusion, allowing preservation of cardioprotection in the mouse myocardium. This...
متن کاملThe paradigm of postconditioning to protect the heart
Ischaemic preconditioning limits the damage induced by subsequent ischaemia/reperfusion (I/R). However, preconditioning is of little practical use as the onset of an infarction is usually unpredictable. Recently, it has been shown that the heart can be protected against the extension of I/R injury if brief (10-30 sec.) coronary occlusions are performed just at the beginning of the reperfusion. ...
