BACKGROUND: Intravenous thrombolysis (IVT) with alteplase or tenecteplase before mechanical thrombectomy is the recommended treatment for large-vessel occlusion acute ischemic stroke. There are divergent data on whether these agents differ in terms of early recanalization (ER) rates before mechanical thrombectomy, and little data on their potential differences stratified by ER predictors such as IVT to ER evaluation (IVT-to-EReval ) time, occlusion site and thrombus length. METHODS: We retrospectively compared the likelihood of ER after IVT with tenecteplase or alteplase in anterior circulation large-vessel occlusion acute ischemic stroke patients from the PREDICT-RECANAL (alteplase) and Tenecteplase Treatment in Ischemic Stroke (tenecteplase) French multicenter registries...

Gonnot et al. [1] thoroughly investigated the regulatory role of glycogen synthase kinase 3 beta (GSK3β) in modulating cardiac isoform 2 of sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA2) activity. They have found that in ischemic hearts of patients and mouse-GSK3β -mediated SERCA2 phosphorylation at serine 663 dampens the SERCA2 pump activity and induces Ca2+ overload which sensitizes towards myocardial ischemia-reperfusion (I/R) injury. The inhibition of serine 663 phosphorylation significantly increases SERCA2 activity and, by preventing cytosolic and mitochondrial Ca2+ overload, reduces cell death during reperfusion...

INTRODUCTION AND OBJECTIVES: Prognosis in ST-elevation myocardial infarction (STEMI) is determined by delay in primary percutaneous coronary intervention (PPCI). The impact of first medical contact (FMC) facility type on reperfusion delays and mortality remains controversial. METHODS: We performed a prospective registry of primary coronary intervention (PCI)-treated STEMI patients (2010-2020) in the Codi Infart STEMI network. We analyzed 1-year all-cause mortality depending on the FMC facility type: emergency medical service (EMS), community hospital (CH), PCI hospital (PCI-H), or primary care center (PCC)...

Background/Aim: Music-based therapy plays a role in central nervous system diseases. We aimed to explore the effect of different doses and durations of music therapy on motor function recovery after stroke and the underlying molecular mechanisms. Methods: Adult male Sprague-Dawley rats were subjected to middle cerebral artery occlusion (MCAO) for 1 h, which was followed by reperfusion. In experiment 1, the rats that survived 1 week after MCAO surgery were randomly allocated into four groups ( n = 10 per group): MCAO group, 1 h music group (Mozart K...

There is some recent evidence that cardiac ischemia/reperfusion (I/R) injury induces intestinal damage within days, which contributes to adverse cardiovascular outcomes after myocardial infarction. However, it is not clear whether remote gut injury has any detectable early signs, and whether different interventions aiming to reduce cardiac damage are also effective at protecting the intestine. Previously, we found that chronic treatment with rofecoxib, a selective inhibitor of cyclooxygenase-2 (COX-2), limited myocardial infarct size to a comparable extent as cardiac ischemic preconditioning (IPC) in rats subjected to 30-min coronary artery occlusion and 120-min reperfusion...

BACKGROUND: Diabetes mellitus predicts poorer outcomes in patients with acute coronary syndrome (ACS), but the magnitude of this association in patients at older ages remains controversial. METHODS: Data were extracted from the Codi Infart database. All consecutive patients with diagnosis of ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) between 2010 and 2015 were included. We assessed the impact of diabetes mellitus on 30-day and one-year mortality in patients aged less than and at least 75 years...

PURPOSE: To identify protein malonylation, succinylation and glutarylation in human and rat serum. EXPERIMENTAL DESIGN: We employed immunoprecipitation coupled tandem mass spectrometry to compare the relative abundance of malonylation, succinylation and glutarylation of serum protein in acute myocardial infarction human and rat. RESULTS: We found 130 and 48 unique malonylated, succinylated or glutarylated peptides in human and rat serum respectively...

INTRODUCTION: Despite the decreasing incidence rate of acute coronary syndromes worldwide, the incidence of NSTEMI (Non- ST elevation myocardial infarction) has increased relative to STEMI (ST elevation myocardial infarction). The aim of this study was to compare long-term survival rates of NSTEMI and STEMI patients and to explore the effects of risk factors on survival. MATERIAL AND METHODS: All patients hospitaized for acute myocardial infarction at Landspitali University Hospital during the calendar year of 2006 were included in the study...

INTRODUCTION AND OBJECTIVES: ST-segment elevation myocardial infarction (STEMI) network activation by a noncardiologist reduces delay times but may increase the rate of false-positive STEMI diagnoses. We aimed to determine the prevalence, predictors, and clinical impact of false-positive activations within the Catalonian STEMI network (Codi Infart). METHODS: From January 2010 through December 2011, all consecutive patients treated within the Codi Infart network were included...

INTRODUCTION AND OBJECTIVES: The benefit of primary angioplasty may be reduced if there are delays to reperfusion. Identification of the variables associated with these delays could improve health care. METHODS: Analysis of the Codi Infart registry of Catalonia and of the time to angioplasty depending on the place of first medical contact. RESULTS: In 3832 patients analyzed, first medical contact took place in primary care centers in 18% and in hospitals without a catheterization laboratory in 37%...

OBJECTIVE: To assess the impact of gender upon the prognosis and medical care in a regional acute ST-elevation myocardial infarction management network. DESIGN: An observational study was made of consecutive patients entered in a prospective database. SCOPE: The Catalan acute ST-elevation myocardial infarction management network.

OBJECTIVE: The ST-segment elevation myocardial infarction network "Codi Infart" was implemented in Catalonia (Spain) in June 2009. The objective of this study was to evaluate the impact of the implementation of the Codi Infart on women. METHOD: Women referred for primary percutaneous coronary intervention, were divided into two groups according to Codi Infart: Non-Codi Infart group (January 2003 to May 2009) and Codi Infart group (June 2009 to December 2012)...

BACKGROUND: A prospective single-center interventional cohort study was conducted to evaluate the effects of a 5-week comprehensive cardiac rehabilitation program on terms exercise capacity, quality of life, echocardiographic findings and autonomic modulation after first-time myocardial infarction. METHODS: We studied 37 consecutive post-myocardial infartion patients (mean age 66 years). All patients began a 5-week cardiac rehabilitation supervised training. The exercise program consisted of 40 minutes of training, three times a week, on a cycle ergometer at 60-80% of the maximal heart rate...

Myocardial infarction (MI) is the leading cause of death worldwide, and extensive research has therefore been performed to find a cure. Neuregulin-1 (NRG) is a growth factor involved in cardiac repair after MI. We previously described how biocompatible and biodegradable microparticles, which are able to release NRG in a sustained manner, represent a valuable approach to avoid problems related to the short half-life after systemic administration of proteins. The effectiveness of this strategy could be improved by combining NRG with several cytokines involved in cardiac regeneration...

OBJECTIVE: We aimed to investigate the association between the ABO blood groups and the risk of coronary artery disease (CAD) and myocardial infartion (MI) in a young Taiwanese population. METHODS: We retrospectively recruited 277 consecutive subjects (men younger than 45 years and women younger than 55 years) who underwent coronary angiography (136 with documented CAD and 129 without CAD) at our center, between 2005 and 2008. Their ABO blood groups were determined using standard agglutination techniques...

OBJECTIVE: To investigate the influence of Auricularia Auricular polysaccharide (APP) on acute cerebral injury induced by ischemia/reperfusion in rats and its underlying mechanism.
