Myocardial stunning, hibernation, and ischemic preconditioning

Journal of Cardiothoracic and Vascular Anesthesia, 1996
From the present review, it may be concluded that myocardial ischemia results in far more complicated syndromes than previously realized. Although not all aspects of the issues discussed in this review are currently a clinical reality in the daily practice of cardiovascular anesthesiologists, the understanding and application of these concepts are ...

Ischemic preconditioning, myocardial stunning and anesthesia

Current Opinion in Anaesthesiology, 2000
Brief periods of ischemia have been shown to protect the heart against a subsequent prolonged ischemic insult, a phenomenon known as ischemic preconditioning. The protective effects of preconditioning markedly reduce myocardial ischemic injury in vivo. Volatile anesthetics have been shown to protect myocardium against infarction by a mechanism similar ...

Ischemic preconditioning increases myocardial O-GlcNAc glycosylation

Scandinavian Cardiovascular Journal, 2013
Through the hexosamine biosynthetic pathway (HBP) proteins are modified by O-linked-β-N-acetylglucosamine (O-GlcNAc), which acts as a stress sensor. Augmentation of O-GlcNAc confers cardioprotection against ischemia- reperfusion injury, but its role in ischemic preconditioning (IPC) is unknown.

Myocardial Ischemic Preconditioning

1994
Protection of ischemic myocardium through transient antecedent sublethal ischemia (myocardial ischemic preconditioning, IP) is a well established laboratory phenomenon which has caught the attention and imagination of clinicians and researchers throughout the world.

Naloxone Blockade of Myocardial Ischemic Preconditioning is Stereoselective

Journal of Molecular and Cellular Cardiology, 1996
This study tested the hypothesis that endogenous opioids are involved in the infarct limitation of myocardial ischemic preconditioning (IP). Blockade of IP-induced infarct limitation by (-)naloxone hydrochloride (-NAL) or its receptor-inactive stereoisomer (+)naloxone (+NAL) was evaluated.

Myocardial ischemic preconditioning and mitochondrial F1F0-ATPase activity

Molecular and Cellular Biochemistry, 2000
A short period of ischemia followed by reperfusion (ischemic preconditioning) is known to trigger mechanisms that contribute to the prevention of ATP depletion. In ischemic conditions, most of the ATP hydrolysis can be attributed to mitochondrial F1F0-ATPase (ATP synthase).

Ischemic preconditioning reduces neutrophil accumulation and myocardial apoptosis

The Annals of Thoracic Surgery, 1999
This study tested the hypothesis that ischemic preconditioning (IP) inhibits myocardial apoptosis after a short period of ischemia and reperfusion.In 9 anesthetized dogs, the left anterior descending (LAD) coronary artery was occluded for 30 min and reperfused for 3 h (control), while in 9 others, LAD occlusion was preceded by 5 min of occlusion and 5 ...

Myocardial, neural and vascular aspects of ischemic preconditioning

Life Sciences, 1996
Ischemic preconditioning can be obtained with brief coronary occlusions. It has been studied in different animal species including dogs, pigs, rabbits and rats. The suggested duration of the occlusions ranges from four periods of 5 min, separated from each other by 5 min of reperfusion, to one period of 2.5 min. In addition to the reduction of the size

EFFECTIVENESS OF ISCHEMIC PRECONDITIONING ON LONG-TERM MYOCARDIAL PRESERVATION

Transplantation, 1998
This study was designed to assess whether the protective effect of ischemic preconditioning can be adapted for myocardium undergoing 6 hr of ischemia.Eighteen isolated rat hearts were perfused with oxygen-bicarbonated Krebs-Henseleit buffer in the Langendorff mode for 35 min (group A, controls) or perfused in the Langendorff apparatus for 20 min ...
