[Role of stress in myocardial protection of ischemic preconditioning].
Zhong nan da xue xue bao. Yi xue ban = Journal of Central South University. Medical sciences, 2015To determine the role of stress in myocardial protection of ischemic preconditioning (IPC).Thirty rabbits were randomly divided into an IPC group, an etomidate (Etom) group, an ischemic/reperfusion (IR) group, a methylprednisolone (MP) group and a sham group. The ratio of infarction size versus risk area (infarct/risk) was calculated. The elevations of

[Nitric oxide and myocardial ischemic preconditioning].
Journal de la Societe de biologie, 2001Preconditioning is an endogenous mechanism of cardioprotection that develops secondary to a brief ischemia and a dramatic reduction in infarct size is observed when the myocardium undergoes a subsequent and long period of ischemia after the induction of preconditioning.

[Ischemic preconditioning and metabolism of myocardial adrenaline].
Kardiologiia, 2010We implanted under urethane narcosis microdialysis probes into myocardium of Wistar rats. In experimental group we used ischemic preconditioning. After this left descending coronary artery was occluded for 60 minutes and then reperfused for 60 min. In control group prolonged occlusion was preceded by 30 min of rest.

Ischemic preconditioning (Pre-con) is an adaptive response triggered by a brief ischemia applied before a prolonged coronary occlusion. We tested the hypothesis that repetitive ischemia applied during early reperfusion, i.e., postconditioning (Post-con), is cardio-protective by attenuating reperfusion injury.

International Journal of Legal Medicine, 2018
The immunohistochemical detection of dityrosine, troponins I (cTNI) and T (cTnT), and connexin 43 has been proposed as a tool for the diagnosis of myocardial infarction with short survival times. Results of clinical and experimental studies reveal that gender and/or ischemic preconditioning of the heart may have an influence on severity and magnitude ...

Effect of Ischemic Preconditioning on Myocardial Oxygen Consumption During Ischemia
Journal of Molecular and Cellular Cardiology, 1998Ischemic preconditioning (IPC) in the heart may reduce myocardial energy demand. The present study was undertaken to examine changes in myocardial oxygen consumption (MVO2) during ischemia by IPC in Langendorff perfused rat hearts. We assessed MVO2 during ischemia from the measurement of mitochondrial cyt.

Non Ischemic Myocardial Preconditioning by Tachycardia and Exercise
2003Myocardial preconditioning can be induced not only by ischemia but also by physiological stimuli like tachycardia and exercise. We studied in dogs the preconditioning effect of tachycardia. Five brief periods of tachycardia prior to occluding a coronary artery followed by reperfusion, reduced the infarct size by about 50%.

[Role of norepinephrine in myocardial ischemia and ischemic preconditioning].
Uspekhi fiziologicheskikh nauk, 2009A brief preceding ischemia-reperfusion can reduce infarct size; this is known as ischemic preconditioning. During myocardial ischemia, massive norepinephrine is released from the cardiac sympathetic nerve terminals, reflecting the sympathetic nerve injury, and producing myocardial damage.

[Ischemic preconditioning: concept of endogenous myocardial protection].
Archives des maladies du coeur et des vaisseaux, 1995Preconditioning 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.
