The clinical value of ischemic conditioning during percutaneous coronary intervention (PCI) and mode of administration is controversial. Our aim was to assess the long-term effect of remote ischemic postconditioning among patients undergoing PCI. We randomized 360 patients undergoing PCI who presented with a negative troponin T at baseline into 3 groups: 2 groups received remote ischemic postconditioning (with ischemia applied to the arm in 1 group and to the thigh in the other group), and the third group acted as a control group...

AIMS: Remote ischaemic conditioning (RIC) releases a humoural factor able to exert cross-species cardioprotection when plasma dialysate is applied to isolated hearts. However, the exact chemical nature of this factor is currently unknown. METHODS AND RESULTS: RIC (4 × 5min femoral occlusion/5min reperfusion) was applied to 10 male pigs, and blood was taken before and after the manoeuvre. Discriminant analysis of (1)H-NMR spectra (n = 10-12) obtained from plasma dialysates (12-14 kDa cut-off) allowed to demonstrate a different metabolic profile between control and postRIC samples, with lactate (2...

Ischemia/reperfusion injury adversely affects the final infarct size (IS) after primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Few studies have evaluated the role of remote ischemic conditioning (RIC) in reducing ischemia/reperfusion injury. However, the results of these studies were not consistent, and an overview of overall effectiveness of this technique in patients with STEMI is lacking. We conducted this meta-analysis to evaluate the available evidence in literature regarding the application of RIC in patients with STEMI who underwent primary PCI...

Hypercholesterolemia 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 hypercholesterolemia affects global cardiac gene expression profile, among many other factors, increased myocardial oxidative stress, mitochondrial dysfunction and inflammation trigger apoptosis and this may account for myocardial dysfunction and increased susceptibility of the myocardium to infarction. In addition, numerous experimental and clinical studies revealed that hyperlcholesterolemia may interfere with the cardioprotective potential of conditioning mechanisms...

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...

BACKGROUND: Clinical heart failure (HF) occurs frequently after ST-segment elevation myocardial infarction (STEMI), and is associated with increased mortality. We assessed the impact of remote ischemic peri-conditioning (RIPC) during inter-facility air medical transport of STEMI patients on clinical HF following primary percutaneous coronary intervention (pPCI). METHODS: Data from Acute Coronary Treatment and Intervention Outcomes Network Registry®-Get With the Guidelines™ (ACTION Registry-GWTG) from two PCI-hospitals that are utilizing RIPC during inter-facility helicopter transport of STEMI patients for pPCI between March, 2013 and September, 2015 were used for this study...

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 amount of investigations based on non-targeted metabolomics has increased, although often without thorough assessment of analytical strategies applied to acquire data. Following published guidelines for metabolomics experiments, we report a validated non-targeted metabolomics strategy with pipeline for unequivocal metabolites identification 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...

Cardioprotective strategies aim to salvage myocardium from ischemia/reperfusion injury and to reduce infarct size and its consequences. Different stimuli, acting at sites remote from the heart (remote conditioning), activate molecular self-defense mechanisms at the target organ heart as well as in other parenchymal organs. Remote conditioning of the heart has been established in many experimental studies and successfully translated to patients. Remote ischemic conditioning by short repetitive cycles of ischemia/reperfusion on an extremity reduces infarct size and improves the prognosis of patients with reperfused myocardial infarction...

Intestinal ischemia followed by reperfusion leads to local and remote organ injury attributed to inflammatory response during the reperfusion phase. The extent to which ischemia contributes to ischemia/reperfusion injury has not been thoroughly studied. After careful evaluation of intestinal tissue following 30 min of ischemia, we noticed significant local mucosal injury in wild-type mice. This injury was drastically reduced in C3-deficient mice, suggesting C3 involvement. Depletion of circulating complement with cobra venom factor eliminated, as expected, injury recorded at the end of the reperfusion phase but failed to eliminate injury that occurred during the ischemic phase...

BACKGROUND: Remote ischemic conditioning (RIC) has been shown to be a practical method for protecting the heart from ischemic/reperfusion (I/R) injury. In the present study, we investigated whether or not the combination of RIC and Astragaloside IV (AS-IV) could improve cardioprotection against acute myocardial infarction (AMI)-induced heart failure (HF) when compared with individual treatments. MATERIAL AND METHODS: A rat model of AMI was established via permanent ligation of the left anterior descending coronary artery (LAD)...

Rotation thromboelastometry is a viscoelastometric method that provides a rapid assessment of a patient's hemostatic processes in emergency settings, allowing prompt identification of specific coagulation abnormalities. Its results thus might guide targeted replacement therapy in hemorrhagic conditions, in case of platelet or coagulation factor deficiency, or hyperfibrinolysis, which is difficult to identify otherwise. Although currently used in emergency and traumatic surgery, there are limited data about thromboelastometry in ischemic stroke, particularly in monitoring the coagulative response to recombinant tissue plasminogen activator after intravenous thrombolysis (IVT)...

BACKGROUND: Previous studies indicate that remote ischemic conditioning performed before percutaneous coronary intervention (PCI) reduces infarct size in patients with ST-elevation myocardial infarction (STEMI). It remains unclear whether remote conditioning affords protection when performed in adjunct to primary PCI. We aimed to study whether remote ischemic per-postconditioning (RIperpostC) initiated after admission to the catheterization laboratory attenuates myocardial infarct size in patients with anterior STEMI...

OBJECTIVE: To assess the impact of remote ischemic peri-conditioning (RIPC) during inter-facility air medical transport of ST-segment elevation myocardial infarction (STEMI) patients on the incidence of acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI). BACKGROUND: STEMI patients who receive pPCI have an increased risk of AKI for which there is no well-defined prophylactic therapy in the setting of emergent pPCI. METHODS: Using the ACTION Registry-GWTG, we evaluated the impact of RIPC applied during inter-facility helicopter transport of STEMI patients from non-PCI capable hospitals to 2 PCI-hospitals in the United States between March, 2013 and September, 2015 on the incidence of AKI following pPCI...

BACKGROUND: Remote ischemic conditioning (RIC) confers protection against myocardial ischemia-reperfusion injury and may modulate coronary blood flow. We investigated whether RIC affects resting myocardial perfusion (MP) in patients with suspected ischemic coronary artery disease by quantitative MP imaging. METHODS AND RESULTS: We included 49 patients with suspected ischemic coronary artery disease. Resting MP was quantified by (82)Rubidium positron emission tomography/computed tomography ((82)Rb-PET/CT) imaging before and after RIC, performed as four cycles of 5 minutes upper arm ischemia and reperfusion...

Cardiovascular diseases and especially myocardial infarctions are responsible for a high morbidity and mortality throughout Europe. An essential aspect of myocardial infarction is ischemia/reperfusion injury which represents the necrosis of myocytes following reperfusion. One possible option to counteract ischemia/reperfusion injury is the much researched process of remote ischemic conditioning (RIC), whereby a certain tissue (e.g. skeletal muscle) is subjected to several cycles of short periods (e.g. 5 min) of ischemia and reperfusion and leads to the protection of another organ (e...

BACKGROUND AND PURPOSE: We tested the hypothesis that limb remote ischemic conditioning (LRIC) treatment promotes arteriogenesis and increases Notch signaling activity during stroke recovery. METHODS: Adult male Sprague Dawley rats were subjected to middle cerebral artery occlusion (MCAO). LRIC was applied after the onset of focal ischemia (per-conditioning), followed by repeated short episodes of remote ischemia 24h after reperfusion (post-conditioning). Cerebral blood flow (CBF) was measured by Laser Doppler Flowmetry...
