BACKGROUND: Multiple randomized controlled trials of remote ischemic preconditioning (RIPC) prior to cardiac surgery have failed to demonstrate clinical benefit. The aim of this updated meta-analysis was to evaluate the effect of RIPC on outcomes following cardiac surgery. METHODS AND RESULTS: Searches of PubMed, Cochrane, EMBASE, and Web of Science databases were performed for 1970 to December 13, 2015. Randomized controlled trials comparing RIPC with a sham procedure prior to cardiac surgery performed with cardiopulmonary bypass were assessed...

Skin wounds may lead to scar formation and impaired functionality. Remote ischemic preconditioning (RIPC) can induce the anti-inflammatory enzyme heme oxygenase-1 (HO-1) and protect against tissue injury. We aim to improve cutaneous wound repair by RIPC treatment via induction of HO-1. RIPC was applied to HO-1-luc transgenic mice and HO-1 promoter activity and mRNA expression in skin and several other organs were determined in real-time. In parallel, RIPC was applied directly or 24h prior to excisional wounding in mice to investigate the early and late protective effects of RIPC on cutaneous wound repair, respectively...

BACKGROUND: The effect of remote ischemic preconditioning (RIPC) and nicorandil on periprocedural myocardial injury (pMI) in patients with planned percutaneous coronary intervention (PCI) remains controversial. The aim of this randomized trial was to evaluate the effect of RIPC or nicorandil on pMI following PCI in patients with stable coronary artery disease (CAD) compared with a control group. METHODS: Patients with stable CAD who planned to undergo PCI were assigned to a 1:1:1 ratio to control, RIPC, or intravenous nicorandil (6mg/h)...

Cardioprotective efficacy of remote ischemic preconditioning (RIPC) remains controversial. Experimental studies investigating RIPC have largely monitored cardiovascular changes during index ischemia and reperfusion with little work investigating changes during RIPC application. This work aims to identify cardiovascular changes associated with autonomic nervous system (ANS) activity during RIPC and prior to index ischemia. RIPC was induced in anesthetized male C57/Bl6 mice by four cycles of 5 min of hindlimb ischemia using inflated cuff (200 mmHg) followed by 5 min reperfusion...

INTRODUCTION: Remote Ischaemic Conditioning (RIC) is a powerful cardioprotective strategy. Its clinical application is simple, cheap and so far free from secondary side effects. Given the heterogeneous results of recent large-scale clinical trials, its clinical relevant benefit is still doubted. EVIDENCE ACQUISITION: Following a MEDLINE-based search on all publications concerning RIC in experimental or clinical settings, this review focuses on the translation from bench to bedside...

BACKGROUND: -Remote ischemic preconditioning (RIPC) can inhibit recurrent ischemic events effectively in patients with acute or chronic cerebral ischemia. However, it is still unclear that whether RIPC can impede ischemic injury after carotid artery stenting (CAS) in patients with severe carotid artery stenosis. METHODS: -Subjects with severe carotid artery stenosis were recruited in this randomized controlled study, and assigned to RIPC, sham and no intervention (control) groups...

Remote ischemic conditioning has been convincingly shown to render the myocardium resistant to a subsequent more severe sustained episode of ischemia. Compared to other organs, little is known regarding the effect of transient liver ischemic conditioning. We proposed the existence cardioprotection induced by remote liver conditioning. Male Sprague Dawley rats were divided into sham-operated, control(CON, no further hepatic intervention) and remote liver ischemic conditioning groups. For liver ischemic conditioning, three cycles of 5min of liver ischemia/reperfusion stimuli were conducted prior to-(liver preconditioning), post-myocardial ischemia (liver postconditioning), or in combination of both (liver preconditioning+liver postconditioning)...

BACKGROUND: Plasma transfusion is a common clinical practice. Remote ischemic preconditioning (RIPC) protects organs against ischemia-reperfusion (IR) injury. Whether preconditioned plasma (PP), collected at late phase after RIPC, could protect organs against IR injury in vivo is unknown. This study explored whether transfusion of PP could reduce myocardial infarct size (IS) after IR in rat in vivo. METHODS: Eighty Lewis rats were randomized to eight groups (n = 10 for each group)...

BACKGROUND/AIMS: A combination sevoflurane postconditioning (SPC) and remote ischemic preconditioning (RIPC) is proved effective in an ex vivo rat heart perfusion model. However, the combined effect of those two interventions is not tested in rat myocardial ischemia/reperfusion (I/R) model, and the underlying mechanisms remain to be elucidated. This study aimed to investigate the effect in vivo using a rat myocardial I/R model and illuminate the related mechanisms. METHODS: Forty male Sprague-Dawley rats were randomly divided into the following 5 groups: i) sham-operated control; ii) I/R; iii) I/R + RIPC; iv) I/R + SPC; v) I/R + RIPC + SPC...

BACKGROUND: In animal studies, remote ischemic preconditioning (RIPC) and anesthetic preconditioning are successful in reducing renal ischemia reperfusion injury (IRI), however the protective effect of RIPC may be improved by repeating the RIPC stimulus. METHODS: Sprague-Dawley rats underwent unilateral nephrectomy followed by 30 min of renal pedicle clamping. Animals were allocated into six groups: sham, control (IRI), RepISO (daily isoflurane anesthesia), RIPC (single dose isoflurane anesthesia and single dose RIPC), RepISO + RIPC (7-day isoflurane anesthesia and single dose RIPC) and RepISO + RepRIPC (7-day isoflurane anesthesia with 7-day RIPC)...

Decreased blood flow supply to the kidneys known as renal ischemia/reperfusion is a common occurrence during various clinical and surgical settings. This remains highly concerning as it is a major cause of acute kidney injury (AKI). The kidneys have a rich supply of efferent and afferent sympathetic nerves playing a crucial physiological role in regulation of renal function. Studies in animal models of renal ischemia/reperfusion injury have indicated that very early during an ischemic event, the sympathetic nerves are activated and in concert with decreased nitric oxide availability, increased angiotensin II and several other molecules results in renal damage...

BACKGROUND: Remote ischemic preconditioning (RIPC), a phenomenon in which a transient ischemia applied to a nonvital tissue protects another organ or tissue from subsequent lethal ischemic injury, is reported to protect the myocardium to withstand a subsequent prolonged ischemic event in patients undergoing cardiac surgery with cardiopulmonary bypass. It remains unclear whether oxidative stress and endogenous antioxidant enzymes play a role in the mechanistic pathways of RIPC. The aim of the present study was to evaluate the effects of RIPC on oxidative stress and extracellular concentrations of melatonin, extracellular superoxide dismutase (eSOD) and extracellular glutathione peroxidase (eGPx) in patients undergoing cardiac surgery with cardiopulmonary bypass...

Hypercholesterolaemia is considered to be a principle risk factor for cardiovascular disease, having direct negative effects on the myocardium itself, in addition to the development of atherosclerosis. Since hypercholesterolaemia affects the global cardiac gene expression profile, among many other factors, it results in increased myocardial oxidative stress, mitochondrial dysfunction and inflammation triggered apoptosis, all of which may account for myocardial dysfunction and increased susceptibility of the myocardium to infarction...

BACKGROUND: Remote ischemic conditioning has been shown to confer myocardial protection. However, there is still no sufficient data on its long-term clinical outcomes. We analyzed the long-term results of the Remote Ischemic Preconditioning and Postconditioning Outcome (RISPO) trial in cardiac surgery patients. METHODS: In the RISPO trial, 1280 patients were randomized to receive remote ischemic preconditioning (RIPC) with postconditioning (RIPostC, upper arm ischemia by four cycles of 5-min inflation followed by 5-min deflation of a pneumatic cuff, N=644) or sham (N=636) during cardiac surgery...

PURPOSE: Ischemic preconditioning (IPC), including remote IPC (rIPC) and direct IPC (dIPC), is a promising method to decrease ischemia-reperfusion (IR) injury. This study tested the effect of both rIPC and dIPC on the genes for antioxidant enzymes and endoplasmic reticulum (ER) stress-related proteins. MATERIALS AND METHODS: Twenty rats were randomly divided into the control and study groups. In the control group (n=10), the right hind limb was sham-operated. The left hind limb (IscR) of the control group underwent IR injury without IPC...

BACKGROUND: Ischemic preconditioning (IPC) protects the heart from prolonged ischemic insult and reperfusion injury through a poorly understood mechanism. Post-translational modifications of histone residues can confer rapid and drastic switches in gene expression in response to various stimuli, including ischemia. The aim of this study was to investigate the effect of histone methylation in the response to cardiac ischemic preconditioning. METHODS AND RESULTS: We used cardiac biopsies from mice subjected to IPC to quantify global levels of 3 of the most well-studied histone methylation marks (H3K9me2, H3K27me3, and H3K4me3) with Western blot and found that H3K9me2 levels were significantly increased in the area at risk compared to remote myocardium...

A 2×2 factorial design was used to evaluate possible preservation of mitochondrial functions in two cardioprotective experimental models, remote ischemic preconditioning and streptozotocin-induced diabetes mellitus, and their interaction during ischemia/reperfusion injury (I/R) of the heart. Male Wistar rats were randomly allocated into four groups: control (C), streptozotocin-induced diabetic (DM), preconditioned (RPC) and preconditioned streptozotocin-induced diabetic (DM+RPC). RPC was conducted by 3 cycles of 5-min hind-limb ischemia and 5-min reperfusion...

Yearly, 13,2% of all deaths are attributable to coronary artery disease (CAD), which with 7.4 million deaths makes CAD leading cause of death in the world. In this review we discuss current knowledge in pathophysiology of atherosclerosis with its progression to stable CAD and its destabilization and complication with thrombus formation - myocardial infarction (MI). Next, we describe mechanisms of myocardial cell death in MI, ischemia-reperfusion injury, left-ventricular remodeling and complications of MI. Furthermore, we add acute management strategies concentrating on medical therapy, decision on reperfusion strategy, timing and cardiac protection by ischemic preconditioning, postconditioning and remote ischemic conditioning...

In recent years, the number of investigations based on nontargeted metabolomics has increased, although often without a thorough assessment of analytical strategies applied to acquire data. Following published guidelines for metabolomics experiments, we report a validated nontargeted metabolomics strategy with pipeline for unequivocal identification of metabolites using the MSMLS molecule library. We achieved an in-house database containing accurate m/z values, retention times, isotopic patterns, full MS, and MS/MS spectra...
