Functional coronary microvascular injury evident as increased permeability due to brief ischemia and reperfusion.

Although morphological studies suggest that coronary vascular injury is a result of prolonged ischemia and subsequent reperfusion, whether functional coronary microvascular injury develops during brief in vivo ischemia is unclear. In other organs, permeability is a sensitive indicator of functional vascular injury. Therefore, a new double-indicator method of assessing vascular protein permeabil...

Coronary Vascular Endothelial Injury Due to Ischemia and Reperfusion

A possible cause of the coronary endothelial injury that occurs with ischemia and reperfusion is the local accumulation of leukocytes during these events. To investigate the role of leukocytes in coronary endothelial injury, we tested the effect of leukocyte removal by filtering on coronary endothelial function in a canine model of regional myocardial ischemia and reperfusion. Blood was supplie...
