- 1├óÔé¼ÔÇ£3 cTns, structural proteins unique to the heart, are sensitive and specific biochemical markers of myocardial damage. (radcliffecardiology.com)
- For example, research with animals found that supplementation with PQQ decreased the size of the area of the heart injured by acute coronary artery blockage . (lifeextension.com)
- Therefore, attenuating myocardial I/R injury during the heart transplant procedure would have a favorable impact on improving short- and long-term graft function and recipient's survival(6). (researchsquare.com)
- The resistant state of skeletal myoblasts to ischemia renders these cells suitable candidates for repair of chronically infracted and failing heart (5). (escardio.org)
- We have recently shown that postischemic administration of intralipid protects the heart against ischemia-reperfusion injury. (silverchair.com)
- In addition, it has been shown that atorvastatin can protect the isolated mouse heart against reperfusion-induced injury [ 6 ]. (ac.ir)
- With ischemia in coronary heart disease, impairment of the oxygen supply and metabolic disorder both occur [ 2 ]. (biomedcentral.com)
- Facilitation of glucose utilization contributes to the protective effect of AKT signaling to reduce infarct size and improve myocardial function in a heart subjected to I/R [ 15 ]. (biomedcentral.com)
Induces1
- The uncoupling of glycolysis and glucose oxidation induces lactate accumulation during myocardial ischemia/reperfusion (I/R) injury. (biomedcentral.com)
Mechanisms3
- 2 Paradoxically, reperfusion itself can enlarge the infarct size, by complex mechanisms collectively termed ischemia/reperfusion injury. (dovepress.com)
- The key mechanisms underlying myocardial I/R injury include increased intracellular calcium concentration, sudden generation of reactive oxygen species (ROS) and inflammatory cytokines, adenosine triphosphate (ATP) depletion, and development of metabolic acidosis. (researchsquare.com)
- Background Caffeic acidity phenethyl ester (CAPE) has been proven to protect the very center against ischemia/reperfusion (We/R) injury by different mechanisms including its antioxidant effect. (technuc.com)
Attenuate1
- Bone marrow mesenchymal stem cells (BMSCs) have been reported to attenuate myocardial I/R injury via their paracrine effects, which can be enhanced by hypoxic preconditioning. (researchsquare.com)
Apoptotic1
- It was shown that functional Fas system contributes to apoptotic myocardial cell death in response to ischemia/reperfusion injury [ 4 , 5 ]. (ac.ir)
Statin therapy1
- Perioperative statin therapy reduced myocardial injury by regulating myocardial autophagy and activating the phosphorylation of AMPK. (hindawi.com)
Intracellular1
Underwent1
- Anesthetized pigs underwent 90 min of regional LV ischemia and 90 min of reperfusion. (diabetesjournals.org)
