BACKGROUND: High-sensitivity cardiac troponin assays permit use of lower thresholds for the diagnosis of myocardial infarction, but whether this improves clinical outcomes is unknown. We aimed to determine whether the introduction of a high-sensitivity cardiac troponin I (hs-cTnI) assay with a sex-specific 99th centile diagnostic threshold would reduce subsequent myocardial infarction or cardiovascular death in patients with suspected acute coronary syndrome. METHODS: In this stepped-wedge, cluster-randomised controlled trial across ten secondary or tertiary care hospitals in Scotland, we evaluated the implementation of an hs-cTnI assay in consecutive patients who had been admitted to the hospitals' emergency departments with suspected acute coronary syndrome...

Introduction: Chronic kidney disease (CKD) and congestive heart failure (CHF) patients have higher serum B-type natriuretic peptide (BNP), which alters the test interpretation. We aim to define BNP cutoff levels to diagnose acute decompensated heart failure (ADHF) in CKD according to CHF subtype: heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF). Material and methods: We reviewed 1,437 charts of consecutive patients who were admitted for dyspnea...

INTRODUCTION: Fluid overload is one of the major characteristics and complications in patients with chronic kidney disease (CKD). N-terminal pro-brain natriuretic peptide (NT-proBNP) is related to fluid status and fluid distribution. The aim of this study is to investigate the interaction between NT-proBNP and fluid status in adverse clinical outcomes of late stages of CKD. METHODS: We enrolled 239 patients with CKD stages 4-5 from January 2011 to December 2011 and followed up until June 2017...

OBJECTIVES: BNP and NT-proBNP are viewed as comparable in their ability to diagnose and monitor HF in clinical guidelines. However, no recent large-scale study has directly established diagnostic concordance between BNP and NT-proBNP. This study sought to assess diagnostic concordance of BNP and NT-proBNP for ruling in and ruling out heart failure (HF). METHODS: Simultaneous BNP and NT-proBNP testing was performed on 2729 patient samples with routinely ordered BNP testing...

Cardiovascular mortality is very high in chronic and end-stage kidney disease (ESKD). However, risk stratification data are lacking. Sudden cardiac deaths are among the most common cardiovascular causes of death in these populations. As a result, many studies have assessed the prognostic potential of various electrocardiographic parameters in the renal population. Recent data from studies of implantable loop recordings in haemodialysis patients from five different countries have shed light on a pre-eminent bradyarrhythmic risk of mortality...

A prospective observational study was conducted to evaluate the predictive value of interleukin-18 (IL-18) for major adverse cardiovascular events (MACEs) in hemodialysis patients. A total of 85 participants (45 hemodialysis patients and 40 healthy volunteers) with a mean age of 56.3 years were enrolled in this study. Demographic and clinical data were collected. MACE was used as the primary endpoint. Results showed that the hemodialysis patients had higher levels of IL-18 (701.6 ± 88.52 versus 152.0 ± 55...

It is unknown whether the association of high-sensitivity troponin I (hs-TnI) with adverse cardiovascular outcomes varies by the presence of chronic kidney disease (CKD). We examined the association of hs-TnI with adverse cardiovascular outcomes in those with and without CKD in 4,107 (mean age, 64 years; 63% men; 20% black) patients from the Emory Cardiovascular Biobank who underwent coronary angiography. CKD (n = 1,073) was defined as estimated glomerular filtration rate <60 ml/min/1.73 m2 or urine albumin/creatinine ratio >30 mg/g at baseline...

BACKGROUND: Mortality is high among patients undergoing hemodialysis for whom cardiac troponin concentration is a strong predictor of outcome. Modern troponin assays allow measurement of very low concentrations. STUDY DESIGN: Using data from a randomized controlled trial, a cohort analysis to evaluate the prognostic value of very low cardiac troponin T (TnT) concentrations. SETTING & PARTICIPANTS: 1,255 patients with end-stage renal disease and type 2 diabetes mellitus undergoing maintenance hemodialysis from the German Diabetes and Dialysis Study (4D) who had a median follow-up of 4 years...

Measures of cardiac troponin (cTn) may have lower specificity for myocardial infarction in patients with CKD. We examined the diagnostic accuracy of baseline and serial high-sensitivity cTnI (hs-cTnI) measurements for myocardial infarction and 30- and 180-day mortality according to renal function. hs-cTnI was measured (Abbott assay) using sex-specific 99th percentiles (women, 16 ng/L; men, 34 ng/L) in 1555 adults presenting to the emergency department with symptoms suggesting ischemia (NCT02060760). Myocardial infarction was adjudicated along universal definition classification...

AIM: Levels of plasma markers of myocardial fibrosis (galectin-3), stretch (B-type natriuretic peptide (BNP)) and injury (troponin T (TnT)) may be affected by haemodialysis and residual renal function (RRF) in addition to cardiac pathology. We aimed to determine the association of RRF, urine output and haemodialysis itself on clinically important cardiac biomarkers in haemodialysis patients. METHODS: Adult haemodialysis patients underwent venesection pre- and post- haemodialysis followed by echocardiography and inter-dialytic urine collection to calculate RRF (mL/minute/1...

BACKGROUND: End-stage renal disease (ESRD) represents a situation in which persistently elevated levels of cardiac troponins I (cTnI) are frequently found in the absence of clinically evident cardiac disease. Moreover, the effect of hemodialysis (HD) on cTnI levels is not definitively elucidated. The aim of this study was to investigate the effects of HD on cTnI levels in ESRD patients. METHODS: We enrolled 30 asymptomatic ESRD patients on maintenance HD. All the patients were dialyzed thrice weekly...

New assays with lower levels of detection of troponin (« high-sensitivity troponin ») increase the difficulty of interpretation of this test for the diagnosis of acute coronary syndrome in patients with chronic kidney disease (CKD). Their baseline concentration of troponin is frequently above the upper reference level, which lowers its specificity. To improve its diagnostic performance after clinical and electrocardiographic evaluation, cut-off levels 2 to 3 times higher than the standard reference have been suggested...

High-sensitive cardiac troponin T (hs-TnT) is a critical biomarker in diagnosis of acute myocardial infarction (AMI). However, CKD individuals usually have elevated hs-TnT even in the absence of AMI. Our study aimed to explore the optimal cutoff-value of hs-TnT and further to improve diagnostic accuracy of AMI in CKD patients. Clinical data of 489 patients were collected from the maintained database between September 2010 and June 2014. CKD patients with AMI were assigned to CKD+AMI group and CKD patients without AMI were assigned to CKD group...

INTRODUCTION: Repetitive dialysis-induced cardiac injury is associated with elevated troponin levels, inflammation, and longitudinal reduction in cardiac function. Pathogenic autoantibodies to cardiac troponins (cTnAAb) produce inflammatory cardiomyopathy in murine models. This study aimed to explore the possibility that analogous autoimmune processes might occur in hemodialysis (HD) patients, by initially investigating cTnAAb prevalence, and exploring potential links with HD-induced myocardial stunning...

We challenged to identify the cutoff value of cTnT in chronic kidney disease (CKD) patients by point of care assessment way. A single center, prospective cross-sectional study was planned and performed. 201 consecutive patients who were visited emergency room for chest symptoms were enrolled in this study. All patients were performed routine practice for differential diagnosis of chest symptom by cardiologist. Simultaneously, semiquantitative measurement of cTnT was performed using same blood sampling on the blind condition to cardiologists for this study...
