Reperfusion and Revascularization in Acute Myocardial



Early reperfusion minimizes the extent of heart muscle damage and preserves the pumping function of the heart. 2017-10-30 See Reperfusion Traumatology A component of crush syndrome, which occurs when blood flow is reestablished to an organ or tissue exposed to prolonged ischemia; renewed blood flow aggravates tissue damage either by causing additional injury or by unmasking injury sustained during the ischemic period; RI occurs in the heart, intestine, kidney, lung, and muscle, and is due to microvascular damage. reperfusion definition: 1. the action of making blood flow return to normal after the supply has been cut off, especially….

Reperfusion was associated with significantly improved functional outcome in each of the 4.5- to 6-hours, 6- to 9-hours, and wake-up time strata, with no evidence of association between time to randomization and beneficial effect of reperfusion (P = .63). reperfusionの意味や使い方 再潅流 - 約1173万語ある英和辞典・和英辞典。発音・イディオムも分かる英語辞書。 Types of myocardial reperfusion injury Reperfusion arrhythmias. Experimental animal studies from the 1980s by Hearse's group were among the first to describe ventricular arrhythmias specifically induced by reperfusion. 6 In reperfused-STEMI patients, the most commonly encountered reperfusion arrhythmias are idioventricular rhythm, ventricular tachycardia, and fibrillation, 7 all of which are REPERFUSION THERAPY •PCI related delay •Difference between the door-to-balloon time and the door-to-needle time. •Overestimates the reperfusion delay for PCI since PCI reperfusion is immediate while fibrinolytic therapy generally does not reestablish perfusion for about 30 minutes. •Does not reflect quality of reperfusion Reperfusion of ischemic tissues results in the formation of toxic ROS, including superoxide anions (O 2 −), hydroxyl radicals (OH −, hypochlorous acid (HOCl), hydrogen peroxide (H 2 O 2), and nitric oxide–derived peroxynitrite.

Does these arrhythmia occur following primary PCI ? It should isn’t ? Reperfusion is associated with a clearcut increase in the number of episodes of arrhythmia. Some arrhythmias such as sustained ventricular tachycardia, early accelerated idioventricular rhythms (occurring in the first 6 hours) or the bradycardia-hypotension syndrome may be considered as non-invasive criteria of reperfusion.

Does these arrhythmia occur following primary PCI ? It should isn’t ? When ischemia has been present for more than six to eight hours, there will be death of tissue and reperfusion at this point results in the products of dead and devitalized tissue being washed into the systemic circulation. This produces intravascular coagulation and a diffuse inflammatory response with systemic vascular permeability. In some occasions, restoration of blood flow to the damaged myocardium triggers further ischemic cellular damage, this paradoxical effect is known as reperfusion injury. The restoration of blood flow to ischemic tissues causes additional damage, which is termed reperfusion injury.

Microdialysis in Liver Ischemia and Reperfusion Injury

Paradoxically, however, the return of blood flow can result in additional cardiac damage and complications; this is referred to as reperfusion injury [ 1-3 ]. Overview Cerebral hyperperfusion, or reperfusion syndrome, is a rare, but serious, complication following revascularization. Hyperperfusion is defined as a major increase in ipsilateral cerebral •Prompt restoration of NORMAL blood flow in the infarct-related artery is essential to myocardial salvage and mortality reduction in patients with STEMI •Gains from reperfusion are greatest in the first few hours of symptom onset and rapidly decline afterwards FACTORS AFFECTING CHOICE OF REPERFUSION THERAPY Successful reperfusion results in rapid and marked normalization (return) of ST-segment elevations. If the reperfusion is complete (after a total occlusion) the ST-segment is normalized within one hour, and this confirms that the coronary artery flow is patent.

The restoration of blood flow to a part of the body deprived of adequate circulation, e.g., the heart muscle in myocardial infarction or the brain in stroke. This may be accomplished by thrombolytic agents, (e.g., streptokinase or tissue plasminogen activator), or mechanical interventions (e.g., Definition of reperfusion. : restoration of the flow of blood to a previously ischemic tissue or organ.
