May support delayed preconditioning mechanisms in endothelium; leaves open translation to clinical ischemia-reperfusion injury.
Does brief coronary artery occlusion and prolonged reperfusion improve coronary endothelial function in conscious dogs?
Brief ischemic episodes induce delayed enhanced coronary endothelial function via upregulation of NO production, which may be involved in the mechanism of delayed preconditioning.
Kim et al. (1997) studied this question.
