Rosuvastatin is a proven cholesterol lowering medicine, which hereby is assumed to achieve a reduction in cardiovascular events. Apart from it's cholesterol lowering action, rosuvastatin may also increase tolerance against ischemia-reperfusion injury. In dogs rosuvastatin increases the endogenous concentration of adenosine, by enhancing the activity of the enzyme ecto-5'-nucleotidase, which converts adenosine monophosphate into adenosine. We hypothesize that rosuvastatin increases tolerance against ischemia-reperfusion injury by induction of ecto-5'-nucleotidase and thereby increasing adenosine activity. This protective effect of rosuvastatin can be abrogated by using the adenosine receptor antagonist caffeine.

Ischemia Reperfusion Injury

Statins, including rosuvastatin, are drugs that lower plasma cholesterol and prevent atherosclerotic disease. Recent preclinical evidence suggests that statins also increase tissue toleran...
It is our goal to study the mechanism of ischemia-reperfusion injury. Our DIEP-operation is actually a clinical model of ischemia-reperfusion. Ischemia-reperfusion injury has never been di...
The application of tourniquet is indispensable for a bloodless surgical area in total knee arthroplasty surgery. The release of tourniquet produces reactive oxygen species which can cause ...
This study is performed to determine whether a seven day treatment with dipyridamole (slow release, 200mg twice daily) can induce a protective effect against ischemia-reperfusion injury, a...
Cardiovascular disease is the leading cause of death in diabetic patients due to both a high event rate and a worse outcome. A pharmacological intervention that reduces ischemia-reperfusio...
It is well accepted that both rosuvastatin and resveratrol exert neuroprotective effects on cerebral ischemia/reperfusion injury through some common pathways. Resveratrol has also been demonstrated to...
Remote ischemic conditioning (RIC) administered by non-lethal periods of extremity ischemia and reperfusion attenuates ischemia-reperfusion injury. We aimed to investigate the local and systemic coagu...
Ischemia-reperfusion injury is characterized by an increase in oxidative stress and leads to significant morbidity and death. The tyrosine kinase c-Abl is activated by oxidative stress and mediates pr...
Ischemia-reperfusion injury is associated with serious clinical manifestations, including myocardial hibernation, acute heart failure, cerebral dysfunction, gastrointestinal dysfunction, systemic infl...
Thyroid dysfunctions can increase the risk of myocardial ischemia and infarction. However, the repercussions on cardiac ischemia/reperfusion (IR) injury remain unclear so far. We report here the effec...
Adverse functional, metabolic, or structural changes in ischemic tissues resulting from the restoration of blood flow to the tissue (REPERFUSION), including swelling; HEMORRHAGE; NECROSIS; and damage from FREE RADICALS. The most common instance is MYOCARDIAL REPERFUSION INJURY.
Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing MYOCARDIAL REPERFUSION INJURY.
Restoration of blood supply to tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. It is primarily a procedure for treating infarction or other ischemia, by enabling viable ischemic tissue to recover, thus limiting further necrosis. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing REPERFUSION INJURY.
Exposure of myocardial tissue to brief, repeated periods of vascular occlusion in order to render the myocardium resistant to the deleterious effects of ISCHEMIA or REPERFUSION. The period of pre-exposure and the number of times the tissue is exposed to ischemia and reperfusion vary, the average being 3 to 5 minutes.
Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm.
Cholesterol is a waxy steroid metabolite found in the cell membranes and transported in the blood plasma. It is an important structural component of mammalian cell membranes, where it is establishes proper membrane permeability and fluidity. Cholesterol ...
