The association between circRNAs and myocardial ischemia/reperfusion (I/R) injury remains largely unknown. The aim of this study was to test the effects of myocardial I/R circRNA expression and explore the potential roles of these circRNAs. CircRNAs were screened by high-throughput sequencing, and the expression of 2021-03-05 2020-04-21 2019-12-20 2021-01-28 2021-04-06 Myocardial Reperfusion Injury / metabolism.

Myocardial reperfusion injury

Reperfusion injury is manifested as stunned myocardium, reversible microvascular injury, and, rarely, lethal myocyte necrosis. The concept of additional myocardial damage is induced by lethal reperfusion injury has been supported by the observation that interventions started before reperfusion can reduce infarct size, as discussed below [ 4, 5 ]. Studies in animals suggest that lethal reperfusion injury accounts to up to 50% of the final size of a myocardial infarction. The existence of lethal myocardial reperfusion injury has been demonstrated by an overwhelming body of evidence obtained mainly in laboratory experiments, but also, and increasingly, in humans. 2 Different interventions have consistently been shown to limit myocardial necrosis when applied at the time of reperfusion in a variety of models and preparations, and it is unquestionable that, at least under certain conditions, lethal myocardial reperfusion injury occurs. Reperfusion hemorrhage occurs, probably as a result of restitution of flow through severely injured microvasculature allowing leakage of intravascular fluids and cells into interstitial spaces. reperfusion injury The damage, and loss of function, that commonly occurs in the heart muscle when, after a heart attack, the flow of blood to the muscle is restored.

If MRI is occurring, the concept of myocardial infarction must be expanded to include the ischemic and reperfusion phases of myocardial injury. 2007-12-06 2015-04-14 Ischaemia/reperfusion (I/R) injury is at the centre of the pathology of the most common cardiovascular diseases.

doxically, reperfusion itself can actually cause cardiomyocyte death and subsequent irreversible myocardial injury, a phenom-enon termed ‘ischaemia reperfusion injury (IRI)’.9 (Fig. 1). Mitochondrial dysfunction during myocardial ischaemia reperfusion In order to meet the high energy demand for both contractility The myocardial Na + /H + exchanger: a potential therapeutic target for the prevention of myocardial ischaemic and reperfusion injury and attenuation of postinfarction heart failure.

This Review revisits the pathophysiology of myocardial ischaemia-reperfusion injury, including the role of autophagy and forms of cell death such as necrosis, apoptosis, necroptosis and pyroptosis. Other cellular compartments in addition to cardiomyocytes are addressed, notably the coronary microcirculation. 2020-07-03 Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality.

Early reperfusion of acute myocardial infarctions interrupts damage due to ischemia but may itself cause further injury (1-4).

Reperfusion injury is manifested as stunned myocardium, reversible microvascular injury, and, rarely, lethal myocyte necrosis.

Reperfusion of the ischemic myocardium results in irreversible tissue injury and cell necrosis, leading to decreased cardiac performance. While early reperfusion of the heart is essential in preventing further tissue damage due to ischemia, reintroduction of blood flow can expedite the death of vulnerable, but still viable, myocardial tissue, by initiating a series of events involving both Myocardial ischemia and reperfusion injury, clinical and experimental studies.
