Ischemia-reperfusion injury (IRI) is the major cause of acute kidney injury. Remote ischemic conditioning (rIC) performed as brief intermittent sub-lethal ischemia and reperfusion episodes in a distant organ may protect the kidney against IRI. Here we investigated the renal effects of rIC applied either prior to (remote ischemic preconditioning; rIPC) or during (remote ischemic perconditioning;...

BACKGROUND Comprehensive stroke studies reveal diaschisis, a loss of function due to pathological deficits in brain areas remote from initial ischemic lesion. However, blood-brain barrier (BBB) competence in subacute diaschisis is uncertain. The present study investigated subacute diaschisis in a focal ischemic stroke rat model. Specific focuses were BBB integrity and related pathogenic process...

Ischemic heart disease is the leading cause of death and morbidity in the world, and ST-segment elevation myocardial infarction (STEMI) remains associated with a significant mortality rate and complications noted at 1-year follow-up, despite prompt coronary reperfusion achieved with either thrombolysis or primary percutaneous coronary intervention (PPCI). It is therefore clear that novel cardio...

There is currently no effective prophylactic regimen available to prevent contrast-induced AKI (CI-AKI), a frequent and life-threatening complication after cardiac catheterization. Therefore, novel treatment strategies are required to decrease CI-AKI incidence and to improve clinical outcomes in these patients. Remote ischemic preconditioning (rIPC), defined as transient brief episodes of ische...

Background Recanalization of chronic total occlusion (CTO-coronary occlusion > 3 months with a TIMI flow grade 0), is one of the most challenging PCI procedure with specific complications. Late-gadolinium enhancement imaging (LGE) is routinely used to assess viability by exploring transmural and circumferential extent of scar lesions in chronic ischemic regions, but is not able to further chara...

BACKGROUND Protection of remote ischemic preconditioning on neurocognitive function caused by bilateral common carotid artery occlusion has been investigated in rats. MATERIAL/METHODS Thirty-six male Sprague-Dawley rats were divided into 3 groups - control group (Group C, n=12), bilateral carotid arteries occlusion group (Group B, n=12) and remote ischemic precondition group (Group P, n=12). ...

BACKGROUND AND PURPOSE Remote ischemic conditioning is cardioprotective in myocardial infarction and neuroprotective in mechanical occlusion models of stroke. However, there is no report on its therapeutic potential in a physiologically relevant embolic stroke model (embolic middle cerebral artery occlusion) in combination with intravenous tissue-type plasminogen activator (tPA). METHODS We t...

Rationale: Remote ischemic conditioning induced by repeated episodes of transient limb ischemia is a clinically applicable method for protecting the heart against injury at the time of reperfusion. Objective: To assess the effect of chronic, repeated, remote conditioning on infarct size and long-term remodeling after myocardial infarction. D espite the timely application of reperfusion therapy,...

Evaluation of multiorgan protection strategies against ischemic injury in humans is essential to improve quality of life and reduce mortality. Over the past 40 years a host of pharmacologic and non-pharmacologic interventions have been evaluated with the aim of limiting cell damage produced by ischemia-reperfusion injury. Different conditioning strategies, such as remote conditioning, are docum...

Remote ischemic preconditioning (rIPC) has been shown to reduce the extent of myocardial infarction during an ischemic event as well as prior to a planned cardiac intervention. Vigorous exercise has been shown to have similar cardiovascular benefits to remote ischemic preconditioning in healthy individuals. Despite this effect, many individuals who exercise regularly present with cardiovascular...
