Following acute myocardial infarction (MI), early and successful reperfusion is the most effective strategy for reducing infarct size and improving the clinical outcome. However, immediate restoration of blood flow to the ischemic zone results in myocardial damage, defined as "reperfusion-injury". Whereas we previously reported that TVP1022 (the S-isomer of rasagiline, FDA-approved anti-Parkinson drug) decreased infarct size 24 h post ischemia reperfusion (I/R) in rats, in this study we investigated the chronic cardioprotective efficacy of TVP1022 14 days post-I/R...

BACKGROUND AND AIMS: Sepsis is a complex rapidly progressive infectious disease that remain a major cause of morbidity and mortality in surgical patients and trauma victims. Edaravone a novel free radical scavenger was approved in 2001 in Japan for treatment of acute cerebral and myocardial infarction. Hence, in this work we attempt to evaluate its role in cases of septic peritonitis (SP). MATERIAL AND METHODS: This is a prospective randomized observer-blinded study carried out in surgical Intensive Care Unit (ICU) after approval by Hospital Ethical Committee...

BACKGROUND: Studies have shown that acute exercise can increase serum concentrations of cardiac biomarkers, including cardiac troponin T (cTnT). We investigated the acute effects of intermittent (IE) and continuous (CE) exercise at the same cardiac workload on myocardial necrosis biomarkers in sedentary men. METHODS: Eleven sedentary healthy men aged 22.3±1.9years completed the study. The subjects were divided into two groups and performed, in random order, IE (intensity alternating between 50% (2min) and 80% (1min) HRreserve) or CE (60% HRreserve)...

OBJECTIVES: Septic cardiomyopathy is a well-described consequence of septic shock and is associated with increased sepsis-related mortality. The myocardial performance index (MPI), a parameter derived from echocardiographic tissue Doppler measurements, allows for a more sensitive assessment of global cardiac function than do traditional metrics for cardiac function. The authors hypothesized that changes in left ventricular MPI in patients with severe sepsis would be associated with a higher 90-day mortality...

BACKGROUND: Meta-analyses of cardiac rehabilitation trials up to 2010 showed a significant reduction in all-cause mortality but many of these trials were conducted before the modern management of acute coronary syndromes. METHODS: We undertook a meta-analysis of contemporary randomised controlled trials published in the period 2010 to 2015, including patients with other forms of atherosclerotic cardiovascular disease, to investigate the impact of cardiovascular prevention and rehabilitation on hard outcomes including survival...

BACKGROUND: Acute myocardial infarction (MI) causes significant changes in cardiac morphology and function. Galectin-3 is a novel and potentially therapeutically important mediator of cardiac remodelling. Myocardial and serum galectin-3 expression dynamics in response to the early cardiovascular outcomes after acute MI are not fully elucidated. METHODS: We first performed a comprehensive longitudinal microarray analyses in mice after acute MI. We then measured the serum levels of galectin-3 in a translational porcine model of coronary microembolism-induced post-ischaemic cardiac remodelling...

BACKGROUND: Heart type fatty acid protein(HFABP) is a cytosolic protein released early after acute coronary syndrome(ACS) even in the absence of myocardial necrosis. OBJECTIVES: The purpose of this systematic review was to determine whether HFABP levels in patients with suspected, or confirmed ACS, improves risk stratification when added to established means of risk assessment. METHODS: We searched Medline, Pubmed and Embase databases from inception to July 2015 to identify prospective studies with suspected or confirmed ACS, who had HFABP measured during the index admission with at least 1 month follow up data...

Selective agonist of δ2-opioid receptors deltorphin II and its retroenantio analog (0.12 mg/kg intravenously) were preventively injected to male Wistar rats 15 min prior to 45-min coronary occlusion or 5 min before 120-min reperfusion. Administration of deltorphin II before artery occlusion and before reperfusion decreased the infarct size/area at risk ratio. Deltorphin II prevented the appearance of ischemia-provoked ventricular arrhythmias and exerted no effect on HR and BP (systolic and diastolic). The retroenantio analog of deltorphin II produced no antiarrhythmic or infarct-limiting effects, but reduced HR without affecting BP...

Acute myocardial infarction is the leading cause of mortality in the industrialized world. While it is essential to attempt an early reperfusion of ischemic myocardial territories, reperfusion itself adds damage to the heart, the ischemia-reperfusion (I/R) injury. Particularly the injury resulting from the very first minutes of reperfusion remains incompletely understood. MicroRNAs (miRNAs) are dynamic regulators in I/R injury. Nitric oxide (•NO) signaling, in turn, interacts with miRNA signaling. Our previous investigations showed that •NO signaling in I/R could be modulated by nitrite...

Eosinophilic myocarditis is a rare form of myocardial inflammation that is characterized by the infiltration of eosinophilic cells into the myocardium. The clinical symptoms of eosinophilic myocarditis are similar to those of acute coronary syndrome, and eosinophilic myocarditis sometimes occurs in combination with bronchial asthma. We herein present a case of eosinophilic myocarditis in which additional time was required to make a definitive diagnosis because the patient received steroid therapy. The diagnosis of eosinophilic myocarditis is challenging, especially when a patient has other inflammatory diseases, such as bronchial asthma...

Effects of daily fluctuation of ambient temperature and concentrations of air pollutants on acute cardiovascular events have not been well studied. From January 2011 to December 2012, a total of 56,863 consecutive ST-segment elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention were registered from 929 institutes with median interinstitutional distance of 2.6 km. We constructed generalized linear mixed models in which the presence or absence of patients with STEMI per day per institute was included as a binomial response variable, with daily meteorologic and environmental data obtained from their respective observatories nearest to the institutes (median distance of 9...

BACKGROUND: A shorter time to treatment has been shown to be associated with lower mortality rates in acute myocardial infarction (AMI). Several strategies have been adopted with the aim to reduce any delay in diagnosis of AMI: pre-hospital triage with telemedicine is one of such strategies. We therefore aimed to measure the real effect of pre-hospital triage with telemedicine in case of AMI in a meta-analysis study. METHODS: We performed a meta-analysis of non-randomized studies with the aim to quantify the exact reduction of time to treatment achieved by pre-hospital triage with telemedicine...

BACKGROUND: Higher N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels have been linked to a more favorable glucometabolic profile. Little is known about the interaction of NT-proBNP and fasting glucose in non-ST-segment elevation acute coronary syndrome (NSTE ACS). METHODS: Fasting glucose and NT-proBNP were measured in 2240 patients enrolled in the EARLY ACS trial. Multivariable Cox models were used to assess associations between fasting glucose and NT-proBNP and a 96-hour composite of death, myocardial infarction (MI), recurrent ischemia, or thrombotic bailout; 30-day death or MI; and 1-year mortality...

BACKGROUND: Newer P2Y12 inhibitors have more rapid onset of platelet inhibition compared with clopidogrel, especially the intravenous P2Y12 inhibitor cangrelor. Direct comparisons between cangrelor and oral P2Y12 inhibitors ticagrelor and prasugrel do not exist. Thus, we performed a network meta-analysis to directly and indirectly compare different P2Y12 inhibitors in patients undergoing percutaneous coronary intervention (PCI). METHODS: MEDLINE/PubMed and ClinicalTrials...
