TnT hs Shock

BACKGROUND: Septic shock, an extremely dangerous condition that causes impairment of organ function, always largely contributes to mortality in intensive care units. The impact of septic shock-induced organ damage on morbidity and mortality is substantially influenced by myocardial dysfunction. However, it remains unclear whether and in what manner anisodamine (654-1/654-2) ameliorates myocardial dysfunction caused by septic shock. PURPOSE: This study is the pioneering investigation and validation about the protective efficacy of anisodamine (654-1/654-2) against LPS-induced myocardial dysfunction in septic shock rats...

OBJECTIVES: The COVID-19 pandemic and subsequent rise of multisystem inflammatory syndrome in children have raised interest in high-sensitivity troponin (hs-TnT) and N-terminal probrain natriuretic peptide (NT-proBNP) because these have been found to be elevated in many cases of multisystem inflammatory syndrome in children. Our aim was to study hs-TnT and NT-proBNP concentrations in febrile children not affected by COVID-19. METHODS: We retrospectively measured cardiac markers, hs-TnT, and NT-proBNP in leftover blood samples of febrile children (0-18 years) diagnosed and treated in a single-center emergency department (ED) (N = 67) and pediatric intensive care unit (PICU) (N = 19) that participated in a multicenter, prospective study of infection biomarkers (PERFORM)...

BACKGROUND: Patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) still experience a high rate of in-hospital complications. Liver fibrosis (LF) is a risk factor for mortality in the general population. We investigated whether the presence of LF detected by the validated fibrosis 4 (FIB-4) score may indicate ACS patients at higher risk of poor outcome. METHODS: In the prospective ongoing REAl-world observationaL rEgistry of Acute Coronary Syndrome (REALE-ACS), LF was defined by a FIB-4 score > 3...

BACKGROUND: Cardiogenic shock is a very serious postoperative complication in patients undergoing heart valve surgery. Mechanical circulatory support is a recognized method of treating patients with this complication. The aim of the presented study was to assess the usefulness of selected biomarkers in predicting the occurrence of postoperative cardiogenic shock requiring mechanical circulatory support. METHODS: This prospective study was conducted on a group of 712 patients undergoing heart valve surgery...

AIMS: Previous studies have reported the defibrillation testing during implantable cardioverter defibrillator (ICD) implantation is associated with elevated cardiac biomarkers and ST-segment electrocardiogram (ECG) changes suggesting that shocks during testing may cause harm. However, the effects of testing have not been isolated from the implant procedure itself, where lead deployment may cause myocardial damage. This prospective study examined high sensitivity troponin T (hs-TnT) levels and ECG changes during ICD implanting alone, ICD implantation with testing and device testing as a stand-alone procedure...

BACKGROUND: Cardiac troponins are the preferred biomarkers for diagnosing myocardial infarction (MI). High-sensitivity troponin T (hs-TnT) assays have increased sensitivity and enable more rapid diagnosis of infarction. We assessed the prognostic utility of admission hs-TnT to detect outcomes after primary angioplasty for ST-elevation/new left bundle branch block myocardial infarction (STEMI). METHODS: Patients admitted to Auckland City Hospital for acute coronary catheterization with a diagnosis of STEMI between October 2010 and September 2011 were identified, and included if hs-TnT levels were measured at admission...

OBJECTIVE: The fibrin-derived peptide Bbeta15-42 (also called FX06) has been shown to reduce myocardial infarct size following ischemia/reperfusion. Hemorrhagic shock (HS) followed by volume resuscitation represents a similar scenario, whereby a whole organism is vulnerable to reperfusion injury. DESIGN: We subjected male farm-bred landrace pigs ( approximately 30 kg) to HS by withdrawing blood to a mean arterial pressure of 40 mm Hg for 60 minutes. Pigs were then resuscitated with shed blood and crystalloids for 60 minutes, and at this time, FX06 (2...

BACKGROUND: Heat shock proteins (HSPs) are a family of proteins with immunogenic and proinflammatory properties. Human and Chlamydia pneumoniae (Cp) HSP60 were found in patients with stable coronary disease. METHODS AND RESULTS: We measured the levels of anti-Cp-HSP60 and anti-Cp immunoglobulin G (IgG) in 179 patients with unstable angina, 40 with acute myocardial infarction, and 40 with stable angina (SA), as well as 100 control subjects. Forty-one patients with acute coronary syndromes (ACS) were also studied at follow-up...
