(kb.se)
  • As time from symptom onset (artery occlusion) to reperfusion increases, the myocardium available to salvage decreases, which raises the risk of mortality ( 1 , 2 , 3 , 4 and 5 ). (thoracickey.com)

Infarct size1
  • Short series of repetitive cycles of brief reperfusion and re-occlusion of the coronary artery applied at the onset of reperfusion, reduce the infarct size and coronary artery endothelial dysfunction. (eurekaselect.com)
Minutes after coronary occlusion1
  • The pathophysiological basis for using endocardial extent of infarction as a measure of MaR is that previous experimental studies have shown that the endocardial extent of infarction is established approximately 40 minutes after coronary occlusion[ 11 ]. (biomedcentral.com)
Clinical7
  • In the situation of acute coronary occlusion, the myocardium supplied by the occluded vessel is subject to ischemia and is referred to as the myocardium at risk (MaR). Single photon emission computed tomography has previously been used for quantitative assessment of the MaR. It is, however, associated with considerable logistic challenges for employment in clinical routine. (biomedcentral.com)
  • Although the phenomenon of ischaemic preconditioning (IPC) is associated with the desired protective capacity, the necessity of its application before sustained ischaemia limits its clinical potential. (sun.ac.za)
