Ischemic preconditioning in humans: models, mediators, and clinical relevance.
Ischemic preconditioning, a powerful form of endogenous protection against myocardial infarction, has been demonstrated in several animal species and, recently, in isolated human cardiomyocytes. For both logistic and ethical reasons, no clinical study can meet the strict conditions of experimental studies on preconditioning with infarct size as the end-point. Nevertheless, the demonstration of ...
متن کاملRemote Ischemic Preconditioning (RIPC) Modifies Plasma Proteome in Humans
Remote Ischemic Preconditioning (RIPC) induced by brief episodes of ischemia of the limb protects against multi-organ damage by ischemia-reperfusion (IR). Although it has been demonstrated that RIPC affects gene expression, the proteomic response to RIPC has not been determined. This study aimed to examine RIPC induced changes in the plasma proteome. Five healthy adult volunteers had 4 cycles o...
متن کاملEffects of naloxone on myocardial ischemic preconditioning in humans.
OBJECTIVES We attempted to establish whether naloxone, an opioid receptor antagonist, abolishes the adaptation to ischemia observed in humans during coronary angioplasty after repeated balloon inflations. BACKGROUND Experimental studies indicate that myocardial opioid receptors are involved in ischemic preconditioning. METHODS Twenty patients undergoing angioplasty for an isolated stenosis ...
متن کاملNonelectrocardiographic evidence that both ischemic preconditioning and adenosine preconditioning exist in humans.
OBJECTIVES The objective of this study was to use electrocardiogram (ECG)-independent parameters to determine whether preconditioning (PC) exists in humans during percutaneous transluminal coronary angioplasty (PTCA). BACKGROUND Several studies suggest that both ischemia and adenosine induce PC in the human heart during PTCA. However, because almost all of these studies relied on ST-segment s...
متن کاملRemote Ischemic Preconditioning and Diabetic Macular Edema
Objective: Remote Ischemic Preconditioning (RIPC) as the transient ischemia and reperfusion of the arm is a promising method for protecting different tissue from future ischemia. These effects might be mediated through vascular and endothelial growth factor (VEGF) pathway. We investigated the influence of RIPC on diabetic macular edema (DME) as a chronic ischemic condition in patients who were ...
