Objective(s):This study aimed to examine the hypothesis that an antiarrhythmic effect might be obtained by ischemic preconditioning of the liver, and also to characterize the potential underlying mechanisms. Materials and Methods: Male Wistar rats were anesthetized by thiopental sodium (50 mg/kg, IP) followed by IV injection of heparin (250 IU). Remote ischemic preconditioning (RIPC) was induce...
The present study was designed to investigate the possible role of free radicals in cardioprotective effects of ischemic, pharmacological and remote preconditioning. Isolated rat heart was perfused on Langendorff apparatus with Kreb's Henseleit solution and subjected to 30 min global ischemia followed by 120 min reperfusion. To assess myocardial injury, coronary effluent was analyzed for lactat...
Ischemia-reperfusion injury occurs during coronary artery bypass graft operations. Strategies are needed to lower the extent of damage. Attempts to find these strategies have been occurring for more than 40 years, with remote ischemic preconditioning being one method. This review provides a look at potential mechanisms involved in remote ischemic preconditioning, experimental evidence supportin...
INTRODUCTION Cardioprotective properties of volatile agents and of remote ischemic preconditioning have survival effects in patients undergoing cardiac surgery. We performed a Bayesian network meta-analysis to confirm the beneficial effects of these strategies on survival in cardiac surgery, to evaluate which is the best strategy and if these strategies have additive or competitive effects. M...
BACKGROUND Cognitive function impairment is one of the most common complications in elderly patients after surgery, and an ideal nonpharmacological therapy has not yet been identified. Thus, we hypothesized that remote ischemic preconditioning could improve cognitive functions in elderly patients after surgery and investigated the mechanism underlying this effect. METHODS Ninety patients clas...
BACKGROUND Contrast medium-induced acute kidney injury is associated with substantial morbidity and mortality. The underlying mechanism has been attributed in part to ischemic kidney injury. The aim of this randomized, double-blind, sham-controlled trial was to assess the impact of remote ischemic preconditioning on contrast medium-induced acute kidney injury. METHODS AND RESULTS Patients wit...
InReplyWeagreewithDrsRedingtonandCaldarone thatmany animal andhumanstudieshave shownthat a singleor few (≤5) short episodes of remote ischemic preconditioning (typically 5minutes of limb ischemia followed by 5minutes of reperfusion)areprotective formanyorgans (including theheart, brain, and kidney) with few reported adverse effects. However, few studies have examined the long-term effects of re...
Introduction: Ischemic preconditioning (IPC) protects skeletal muscles from ischemia-reperfusion injury and improves physical exercise performance. The purpose of the present study was to determine whether application of remote ischemic preconditioning (RIPC) of upper limbs would affect the pulmonary function tests and the maximal oxygen consumption (VO2max). Methods: Twenty healthy trained...
Remote ischemic preconditioning (RIPC) is an intrinsic phenomenon whereby 3~4 consecutive ischemia-reperfusion cycles to a remote tissue (noncardiac) increases the tolerance of the myocardium to sustained ischemiareperfusion induced injury. Remote ischemic preconditioning induces the local release of chemical mediators which activate the sensory nerve endings to convey signals to the brain. The...
