Background: The aim of this study was to examine high-sensitivity troponin T and I (hsTnT and hsTnI) after a treadmill run under laboratory conditions and to find a possible connection with echocardiographic, laboratory and other assessed parameters. Methods: Nineteen trained men underwent a standardized 2-hour-long treadmill run. Concentrations of hsTnT and hsTnI were assessed before the run, 60, 120 and 180 minutes after the start and 24 hours after the run. Changes in troponins were tested using non-parametric analysis of variance (ANOVA)...

PURPOSE: This study aims to evaluate the association between high sensitivity troponins (hsTn) and mitral annular plane systolic excursion (MAPSE) in patients undergoing cardiac magnetic resonance imaging (cMRI). METHODS: Patients undergoing cMRI were prospectively enrolled. Patients with right ventricular dysfunction (< 50%) were excluded. Blood samples for measurements of hsTn and amino-terminal pro-brain natriuretic peptide (NT-proBNP) were collected at the time of cMRI...

Background Left atrial function (LAF) plays an interactive role between pulmonary and systemic circulation. Cardiac biomarkers, such as amino-terminal pro-brain natriuretic peptide (NT-proBNP) and troponins, might reflect cardiac function. This study aims to evaluate the association between high sensitivity troponins (hsTn) and left atrial function in patients undergoing cardiac magnetic resonance imaging (cMRI). Methods Patients undergoing cardiac magnetic resonance imaging (cMRI) were enrolled prospectively...

Patients presenting to the emergency department with acute chest pain, negative conventional troponin and electrocardiogram require serial testing to rule out acute coronary syndrome (ACS). We studied the association of highly sensitive troponin (hsTn) I with vulnerable plaque features as detected by coronary dual source computed tomography angiography (DSCTA) and determined whether hsTn I at the time of presentation combined with early DSCTA could improve classification of patients as high-risk or low risk for ACS...

OBJECTIVE: High-sensitivity troponin (hsTn) assays detect 10 times lower concentrations of cardiac troponin than conventional assays. We examined the effects of self-reported cocaine use to determine whether those with acute cocaine use being evaluated for ACS are more likely to have elevated hsTnI than those nonusers being evaluated for ACS. METHODS: We conducted a sub-analysis of a prospective cohort of ED patients evaluated for acute coronary syndrome. Recent cocaine use was determined by structured patient interviews...

The introduction of "highly sensitive" cardiac troponin assays (hsTn) has reinforced the evidence that only serial testing incorporated in running algorithms allows a more accurate diagnosis of acute myocardial infarction. In this report, we consider the available evidence supporting the use of fast track protocols for ruling out and ruling in non-ST elevation myocardial infarction (NSTEMI) and compare it with the content of recently released guideline by the European Society of Cardiology, noting some uncomfortable aspects that need urgent clarification and/or revision...

Additional risk stratification may provide more aggressive and focalized preventive treatment to high-risk hypertensive patients according to the Japanese hypertension guidelines. We prospectively investigated the predictive value of high-sensitivity troponin I (hsTnI), both independently and in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP), for incident heart failure (HF) in high-risk hypertensive patients with preserved left ventricular ejection fraction (LVEF). Baseline hsTnI and NT-proBNP levels and echocardiography data were obtained for 493 Japanese hypertensive outpatients (mean age, 68...

OBJECTIVE: To validate the National Institute for Health and Care Excellence (NICE) recommended algorithms for high-sensitivity troponin (hsTn) assays in adults presenting with chest pain. METHODS: International post hoc analysis of three prospective, observational studies from tertiary hospital emergency departments. The primary endpoint was cardiac death or acute myocardial infarction (AMI) within 24 hours of presentation, and the secondary endpoint was major adverse cardiac events (MACE) at 30 days...

The evaluation of patients presenting to the emergency department with suspected acute coronary syndrome (ACS) remains a clinical challenge. The traditional assessment includes clinical risk assessment based on cardiovascular risk factors with serial electrocardiograms and cardiac troponin measurements, often followed by advanced cardiac testing as inpatient or outpatient (i.e. stress testing, imaging). Despite this costly and lengthy work-up, there is a non-negligible rate of missed ACS with an increased risk of death...

OBJECTIVES: This study compared diagnostic accuracy of conventional troponin/traditional coronary artery disease (CAD) assessment and highly sensitive troponin (hsTn) I/advanced CAD assessment for acute coronary syndrome (ACS) during the index hospitalization. BACKGROUND: hsTnI and advanced assessment of CAD using coronary computed tomography angiography (CTA) are promising candidates to improve the accuracy of emergency department evaluation of patients with suspected ACS...

Highly sensitive troponin (hsTn) assays may predict cardiovascular (CV) events and left ventricular (LV) remodeling in patients with heart failure (HF). In this study, 99 subjects with LV systolic dysfunction (LVSD) were followed 10 ± 3 months with serial measurement of hsTnI by a novel method. hsTnI was detectable in all subjects and was above the 99th percentile of a normal population in 56.7 %. Supramedian baseline hsTnI concentration was associated with higher-risk clinical features and shorter time-to-first event (p = 0...

HYPOTHESIS: We examined the hypothesis that a specific myocardial injury marker, namely high sensitive cardiac troponin-I (HsTn-I), is elevated in patients with slow coronary flow (SCF) pattern. AIM: To examine the above hypothesis by studying a group of patients who had undergone coronary angiography for the detection of their chest pain aetiology with SCF pattern despite an angiographically normal coronary arteriogram. METHODS: We evaluated and performed coronary angiography (CAG) of 97 patients with chest discomfort...
