OBJECTIVES: Myocardial dysfunction is well recognized in severe sepsis and septic shock. Echocardiography provides rapid, noninvasive, and bedside evaluation of cardiac function in patients with hemodynamic instability. Mitral annular plane systolic excursion is an M-mode-derived echocardiographic variable used to assess longitudinal left ventricular systolic function. No data are available about the uses of mitral annular plane systolic excursion in children with septic shock. Therefore, we aimed to assess the prognostic significance of mitral annular plane systolic excursion in children with septic shock and to correlate it with the most commonly used measures of left ventricular systolic function and myocardial injury...

BACKGROUND: The Center for Medicare and Medicaid Innovation (CMMI) launched the Bundled Payments for Care Improvement (BPCI) initiative in 2013. A subsequent study showed that the initiative was associated with reductions in Medicare payments for total joint replacement, but little is known about the effect of BPCI on medical conditions. METHODS: We used Medicare claims from 2013 through 2015 to identify admissions for the five most commonly selected medical conditions in BPCI: congestive heart failure (CHF), pneumonia, chronic obstructive pulmonary disease (COPD), sepsis, and acute myocardial infarction (AMI)...

Neutrophils are the most abundant white blood cells, with a vital role in innate immune defense against bacterial and fungal pathogens. Although mostly associated with pathological processes directly related to immune defense, they can also play a detrimental role in inflammatory conditions and have been found to have a pro-metastatic role in the spread of cancer cells. Here, we explore ways to temporarily suppress these detrimental activities. We first examined the possibility of using siRNA and antisense oligonucleotides (ASOs) for transient knockdown of the human and mouse C5a receptor, an important chemoattractant receptor involved in neutrophil-mediated injury that is associated with myocardial infarction, sepsis, and neurodegenerative diseases...

BACKGROUND: The Universal Myocardial infarction (MI) definition divides MIs into different types. Type 1 MIs (T1MI) result spontaneously from atherosclerotic plaque instability. Type 2 MIs (T2MI) are due to secondary causes of myocardial oxygen demand/supply mismatch such as occurs with sepsis. T2MI are much more common among those with HIV than in the general population. T1MI and T2MI have different mechanisms, risk factors and potential treatments suggesting that they should be distinguished to achieve a better scientific understanding of MIs in HIV...

Sepsis is one of the ten leading causes of death in developed and developing countries. In the United States, sepsis mortality approaches that of acute myocardial infarction and exceeds deaths from stroke. Neonates and the elderly are the most vulnerable patients, with these groups suffering from the highest sepsis mortality. In both groups, many survivors respectively display serious developmental disabilities and cognitive decline. The National Institute of Health National Heart Lung and Blood Institute Panel redefined sepsis as a "severe endothelial dysfunction syndrome in response to intravascular and extravascular infections causing reversible or irreversible injury to the microcirculation responsible for multiple organ failure...

Myocardial dysfunction is a major cause of death in sepsis. MicroRNA-146b (miR-146b) has been reported to be related to myocardial disease. However, the role of miR-146b in sepsis as well as myocardial injury is still unclear. Septic cardiac dysfunction in mice was induced by cecal ligation and puncture (CLP) and miR-146b was found increased significantly in the myocardium tissue of CLP mice. It was found that up-regulation of miR-146b by agomiR injection suppressed expression of IL-1β in mice as well as myocardium apoptosis in CLP mice...

The complex pathogenesis of sepsis and septic shock involves myocardial depression, the pathophysiology of which, however, remains unclear. In this study, cellular mechanisms of myocardial depression were addressed in a clinically relevant, large animal (porcine) model of sepsis and septic shock. Sepsis was induced by fecal peritonitis in eight anesthetized, mechanically ventilated, and instrumented pigs of both sexes and continued for 24 h. In eight control pigs, an identical experiment but without sepsis induction was performed...

BACKGROUND: Sepsis is a life-threatening condition that is usually diagnosed when a patient has a suspected or documented infection, and meets two or more criteria for systemic inflammatory response syndrome (SIRS). The incidence of sepsis is higher among people admitted to critical care settings such as the intensive care unit (ICU) than among people in other settings. If left untreated sepsis can quickly worsen; severe sepsis has a mortality rate of 40% or higher, depending on definition...

Troponin I is a cardiac enzyme that is released during myocardial injury. However, cardiac enzymes are non-specific and can occur in many cardiac and non-cardiac pathologies. We aim to (1) describe the range of acute conditions that were associated with raised troponins in the paediatric population in our institution and (2) quantify the extent of troponin elevation and correlate it with the underlying aetiology. We performed a retrospective observational study in a tertiary institution which included patients from 1 January 2009 to 31 December 2013...

Levosimendan and milrinone may be used in place of dobutamine to increase cardiac output in septic patients with a low cardiac output due to impaired cardiac function. The effects of the two inotropic agents on cardiac inflammation and left ventricular (LV) performance were examined in mice with cecal ligation and puncture (CLP)-induced sepsis. CLP mice displayed significant cardiac inflammation, as indicated by highly increased pro-inflammatory cytokines and neutrophil infiltration in myocardial tissues. When continuously given, levosimendan prevented but milrinone exaggerated cardiac inflammation, but they significantly reduced the elevations in plasma cardiac troponin-I and heart-type fatty acid-binding protein, clinical markers of cardiac injury...

It was demonstrated that α1 adrenergic receptor (α1-AR) activation by phenylephrine (PE) attenuated cardiac dysfunction in lipopolysaccharide (LPS) - challenged mice. However, it is unclear whether PE suppresses sepsis-induced cardiomyocyte apoptosis. Here, we investigated the effects of PE on cardiomyocyte apoptosis in LPS-treated adult rat ventricular myocytes (ARVMs) and septic rats induced by cecal ligation and puncture. Cardiomyocyte apoptosis and caspase activity were detected by TUNEL and spectrophotometrical assay, respectively...
