M Toba Obafemi, Homeyra Douglas
OBJECTIVES: Campylobacter jejuni is an unusual cause of myocarditis and could easily be missed. METHODS: We describe a case of a 25 year old man, who presented with 3 day history of vomiting and diarrhoea, followed by chest pain and significant high sensitive troponin rise. RESULTS: The patient's profuse diarrhoea was accompanied by raised inflammatory markers, electrocardiogram changes and evidence of cardiomyopathy on transthoracic echocardiogram...

The role of autoimmunity in cardiovascular (CV) diseases has been increasingly recognized. Autoimmunity is most commonly examined by the levels of circulating autoantibodies in clinical practices. Measurement of autoantibodies remains, however, challenging because of the deficiency of reproducible, sensitive, and standardized assays. The lack of multiplexed assays also limits the potential to identify a CV-specific autoantibody profile. To overcome these challenges, we developed a nanotechnology-based plasmonic gold chip for autoantibody profiling...

REVIEW
Kai M Eggers, Bertil Lindahl
BACKGROUND: The use of sex-specific cutoffs for cardiac troponin (cTn) is currently debated. Although endorsed by scientific working groups, concerns have been raised that sex-specific cutoffs may have only a small clinical effect at the cost of increased complexity in decision-making. METHODS: We reviewed studies investigating the interrelations between high-sensitivity (hs) cTn results and sex, diagnoses, and outcome. Investigated populations included community-dwelling subjects and patients with stable angina, congestive heart failure, or acute chest pain including those with acute coronary syndromes...

BACKGROUND: Sodium glucose co-transporter 2 (SGLT2) inhibitors may reduce cardiovascular and heart failure risk in patients with type 2 diabetes mellitus (T2DM). OBJECTIVES: To examine the effects of canagliflozin on cardiovascular biomarkers in older patients with T2DM. METHODS: In 666 T2DM patients randomized to receive canagliflozin 100 or 300 mg or placebo, we assessed median percent change in serum N-terminal pro-B type natriuretic peptide (NT-proBNP), high-sensitivity troponin I (hsTnI) , soluble (s)ST2, and galectin-3 from baseline to 26, 52, and 104 weeks...

BACKGROUND: Estimation of sudden cardiac death (SCD) risk is an integral part of clinical management of patients with hypertrophic cardiomyopathy (HCM). Identification of novel biomarkers of this disease can provide additional criteria for SCD risk stratification. Soluble suppression of tumorigenicity (sST2) and galectin-3 (Gal-3) are useful biomarkers for prognosis of heart failure (HF). Both of them appear to mediate cardiac fibrosis - an important pathogenetic process in HCM. Data about sST2 and Gal-3 usefulness in patients with HCM are limited...

BACKGROUND: The preventive role of acute occurring of collateral circulation (AOCC) to infarct related artery (IRA) in patients presenting with acute ST-segment elevation myocardial infarction (STEMI) is well known. Therefore, we aimed to investigate whether there is an association between admission plasma 25-(OH) vitamin D (25(OH)D3) levels and grade of collateralization in patients with STEMI. METHODS: We prospectively included 369 STEMI patients within the first 12 h of symptoms onset...

BACKGROUND: Cardiovascular disease (CVD) is the main cause of death in systemic lupus erythematous (SLE) patients. The Framingham score underestimates the risk for CVD in this population. Our study aimed to determine whether serum high-sensitivity cardiac troponin T (HS-cTnT) might help to identify SLE patients at risk for CVD. METHODS: The presence of carotid plaques was prospectively assessed by ultrasound in 63 consecutive SLE patients asymptomatic for CVD and 18 controls...

#11
REVIEW
Thomas Deneke, Carsten W Israel
Sustained ventricular tachyarrhythmia usually occurs on the basis of structural heart disease, particularly coronary heart disease (CAD). Although monomorphic ventricular tachycardia (VT) appears mainly in patients with CAD, it is typically not triggered by acute ischemia, in contrast to polymorphic VT or ventricular fibrillation (VF). To judge if VT is caused by acute ischemia is even more difficult in context with an elevated highly sensitive troponin T which is generally elevated in sustained VT because tachycardia in chronic stable coronary artery sclerosis causes a mismatch between increased oxygen demand and limited oxygen supply...

BACKGROUND: Takotsubo syndrome (TT) and myocardial infarction (MI) share numerous similarities in clinical presentation, ECG modifications and biomarker elevation. We sought to determine whether the ratio of high-sensitivity cardiac troponin T (hs-TnT) to the myocardial fraction of creatine kinase (CKMB) could be a potent discriminator between TT and MI patients. METHODS: We separately present analysis of data from retrospective files and prospectively recruited patients presenting with TT (35 retrospective and 42 prospective), NSTEMI (48 retrospective and 75 prospective) and STEMI (20 retrospective and 39 prospective)...

A questionable scientific approach to measuring at low concentrations and inappropriate censoring of results below certain cut-offs have resulted in the dichotomous classification of troponin assays based on their so-called analytical sensitivity. The definition of "high-sensitivity" cardiac troponin is flawed. Evidence suggests that its apparent diagnostic superiority may be explained by the censoring of data. In the evaluation of the detection and quantification capabilities of analytical methods we recommend alignment with International Union of Pure and Applied Chemistry (IUPAC) guidelines, including reporting of all results...

Copeptin is currently understood as a quantitative marker of endogenous stress. It rises rapidly in multiple acute disorders including acute myocardial infarction. As a single variable, it has only modest diagnostic accuracy for acute myocardial infarction. However, the use of copeptin within a dual-marker strategy together with conventional cardiac troponin increases the diagnostic accuracy and particularly the negative predictive value of cardiac troponin alone for acute myocardial infarction. The rapid rule-out of acute myocardial infarction is the only application in acute cardiac care mature enough to merit consideration for routine clinical care...

BACKGROUND: Fabry disease (FD) is an X-linked lysosomal storage disorder resulting from the α-galactosidase A gene mutations. Enzyme-replacement-therapy (ERT) products for FD currently used include agalsidase alfa and agalsidase beta. There are many reports on efficacy and safety of ERT. However, most of the previous studies are done as a retrospective medical records analysis. METHODS: The Japan Fabry Research - 002 (JFR-002) was a prospective observational clinical study of 36 ERT-naïve FD patients (14 men and 22 women) at baseline (BL) and after initiation of ERT with agalsidase alfa 0...

We describe the adoption of high sensitive troponin I (hsTnI) in clinical practice in two hospital settings in Italy. Samples from 426 consecutive patients (mean age 68.8 ± 17.0) admitted to the Emergency Department with a suspected acute coronary syndrome (ACS) have been tested at admittance and after 3 and 6 hours by contemporary TnI and hsTnI. Results have been compared to the final clinical diagnosis. Troponin was detectable in 68.6% by TnI and 89.9% by hsTnI. Since hsTnI has a lower threshold for females, 38/41 patients with positive values only by hsTnI were women...

A strategy that discharges chest pain patients with negative high-sensitivity troponin and non-ischaemic electrocardiography changes may still result in 0.44% of patients experiencing myocardial infarction within 30 days. We observed that a pragmatic approach that systematically discharged 25 patients on cardio-protective medications of aspirin, metoprolol and atorvastatin followed with prompt (<10 days) coronary computed tomography angiography resulted in no major adverse cardiac event and adverse drug reaction 30 days post-presentation...

OBJECTIVE: Many meta-analyses have provided synthesised likelihood ratio data to aid clinical decision-making. However, much less has been published on how to safely combine clinical information in practice. We aimed to explore the benefits and risks of pooling clinical information during the ED assessment of suspected acute coronary syndrome. METHODS: Clinical information on 1776 patients was collected within a randomised trial conducted across five South Australian EDs between July 2011 and March 2013...

BACKGROUND: Acute heart failure (AHF) is a common presentation in the Emergency Department (ED), and most patients are admitted to the hospital. Identification of patients with AHF who have a low risk of adverse events and are suitable for discharge from the ED is difficult, and an objective tool would be useful. METHODS: The highly sensitive Troponin T Rules Out Acute Cardiac Insufficiency Trial (TACIT) will enroll ED patients being treated for AHF. Patients will undergo standard ED evaluation and treatment...
