Myocardial ischemia-reperfusion injury refers to myocardial damage that occurs as a result of the interaction between substances that accumulate during ischemia and those that are delivered on the subsequent restoration of blood flow. The term ischemia-reperfusion injury describes the experimentally and clinically prevalent finding that tissue ischemia with inadequate oxygen supply followed by successful reperfusion initiates a For this reason, the resulting myocardial damage is often referred to as an ischemia/reperfusion injury. Evidence that reperfusion itself is harmful to the heart comes from studies that showed that certain phenomena first manifest during the reperfusion phase (no-reflow, ventricular arrhythmias) and then worsen as the phase of reperfusion progresses. Ischemia-reperfusion (IR) injury is directly related to the formation of reactive oxygen species (ROS), endothelial cell injury, increased vascular permeability, and the activation of neutrophils and platelets, cytokines, and the complement system.

Hepatic ischemia-reperfusion (HIR) injury is a common pathophysiological process in many clinical settings. This study was designed to compare the protective role of octreotide (somatostatin analogue, OCT) and melatonin (N-acetyl-5-methoxytryptamine, MLT) through the modulation of autophagy against HIR injury in rats.

Author information: (1)Department of Surgery, Royal Postgraduate Medical School, Hammersmith Hospital, London, UK. Ischaemia-reperfusion injury is a complex phenomenon often encountered in surgical practice. The consequences of such injury are local and remote tissue destruction, and sometimes death. Severe reperfusion injury (primary graft failure, ischemia-reperfusion injury) is the most common cause of early death following lung transplantation.

Ischemia/Reperfusion Injury. Neutrophils and inflammatory cytokines have been implicated in ischemia/reperfusion injury. These observations bridge two fundamental areas of biology, cytokines, and free radical reactions. Ischemic injury occurs when the blood supply to an area of tissue is cut off. The incidence of ischemic injury is vast: myocardial infarction, stroke, and other thrombotic events affect more than 1.3 million individuals each year in the USA alone.

Reperfusion of an ischemic area may result, however, in paradoxical cardiomyocyte dysfunction, a phenomenon termed “reperfusion injury.”. Modalities for reperfusion include not only thrombolysis, but also percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), and cardiac transplantation. Central Nervous System Ischemia–Reperfusion Injury Ischemia–reperfusion injury of the central nervous sys-tem (CNS) may occur after stroke, traumatic head injury, carotid endarterectomy, aneurysm repair, or deep hypo-thermic circulatory arrest.

CNS I-R injury is characterized by disruption of the blood–brain barrier, resulting in leukocyte transmigration into the surrounding brain tissues. 2021-02-23 · Primary graft dysfunction (PGD), the clinical manifestation of lung transplant ischemia-reperfusion injury, affects over 50% of lung recipients within the first 72 hours and is the predominant cause of short-term mortality, as well as chronic lung allograft rejection (1, 2). Ischemia-reperfusion injury is defined as the damage triggered by the rapid restoration of the blood supply to a tissue after a period of ischemia.
