HsTnT

We sought to determine how biomarkers known to be associated with hypertension-induced end-organ injury complement the use of systolic blood pressure (SBP) for cardiovascular disease (CVD) risk prediction at different ages. Using data from visits 2 (1990 to 1992) and 5 (2011 to 2013) of the Atherosclerosis Risk in Communities (ARIC) study, 3 models were used to predict CVD (composite of coronary heart disease, stroke, and heart failure). Model A included traditional risk factors (TRFs) except SBP, model B-TRF plus SBP, and model C-TRF plus biomarkers (high-sensitivity troponin T [hsTnT] and N-terminal pro-B-type natriuretic peptide [NT-proBNP])...

OBJECTIVE: to determine the prognostic relevance, clinical characteristics, and 30-day outcomes associated with myocardial injury after noncardiac surgery (MINS) in major general surgery patients. BACKGROUND: MINS has been independently associated with 30-day mortality after noncardiac surgery. The characteristics and prognostic importance of MINS in major general surgical patients have not been described. METHODS: This was an international prospective cohort study of a representative sample of 22,552 noncardiac surgery patients 45 years or older, of whom 4490 underwent major general surgery in 24 centers in 13 countries...

INTRODUCTION: Postoperative myocardial injury after noncardiac surgery is common and is associated with short- and long-term morbidity and mortality. However, the incidence and risk factors for postoperative acute myocardial injury (POAMI) are currently unknown due to inconsistent definitions. METHODS: We systematically searched PubMed and Web of Science to identify studies that applied the change value of preoperative and postoperative cardiac troponins to define cardiac injury...

PURPOSE: Myocardial injury after non-cardiac surgery is closely related to major adverse cardiac and cerebrovascular event and is difficult to identify. This study aims to investigate how to predict the myocardial injury of thoracic surgery and whether intraoperative variables contribute to the prediction of myocardial injury. METHODS: The prospective study included adult patients with high cardiovascular risk who underwent elective thoracic surgery from May 2022 to October 2022...

BACKGROUND: Lifestyles influence atrial fibrillation (AF) risk. Blood biomarkers can characterize the atrial substrate that facilitates the development of AF. Therefore, determining the effect of lifestyle interventions on blood concentrations of biomarkers of AF-related pathways could help understand AF pathophysiology and contribute to AF prevention. METHODS: We studied 471 participants enrolled in the PREDIMED-Plus trial, a Spanish randomized trial conducted in adults (55-75 years) with metabolic syndrome and body mass index between 27-40 kg/m 2 ...

BACKGROUND: While low sodium intake (<2.3 g/day) is recommended, there is uncertainty about long-term feasibility and effects on cardiorenal biomarkers in populations with moderate intake. METHODS: In two phase IIb, feasibility, randomised, parallel, open-label, controlled, single-centre trials, individuals aged >40 years with stable blood pressure (BP), without heart failure or postural hypotension were randomised to intensive dietary counselling (target sodium intake <2...

BACKGROUND: The best use of perioperative cardiac biomarkers assessment is still under discussion. Massive postoperative troponin surveillance can result in untenably high workloads and costs for health care systems and potentially harmful interventions for patients. In a cohort of patients at risk for major adverse cardiovascular and cerebrovascular events (MACCEs), we aimed to (1) determine whether preoperative biomarkers can identify patients at major risk for acute myocardial injury in noncardiac surgery, (2) develop a risk model for acute myocardial injury prediction, and (3) propose an algorithm to optimize postoperative troponin surveillance...

PURPOSE: This study aims to investigate whether the administration of salbutamol/budesonide reduced the incidence of myocardial injury in thoracic surgery. METHODS: The randomized controlled trial included 298 patients over 45 and at high-risk for cardiovascular complications after lobectomy. Patients in the experimental group were treated with salbutamol/budesonide after anesthesia induction with fiberoptic bronchoscope. The primary outcome was the incidence rates of myocardial injury, assessed before and three days after the operation...

AIMS: Cardiac functional and structural remodeling in patients with atrial fibrillation (AF) contributes to development of heart failure (HF) as their major cardiovascular comorbidity. Circulating biomarkers may reflect these cardiac alterations. METHODS AND RESULTS: ENGAGE AF-TIMI 48 was a randomized trial of edoxaban vs warfarin in 21,105 patients with AF. We performed a nested biomarker study in 8,765 patients, analyzing high-sensitivity troponin T (hsTnT), N-terminal B-type natriuretic peptide (NT-proBNP), and growth differentiation factor-15 (GDF-15) at baseline and 12 months...

BACKGROUND: This study aimed to determine whether a high level of high-sensitivity troponin T (hsTnT) predicts a positive treadmill test in patients with suspected stable ischemic heart disease (SIHD). METHODS: In all, 366 patients with suspected SIHD were included in the study. We measured the serum hsTnT levels before the treadmill test. The treadmill test was performed according to the Bruce protocol. RESULTS: Of the 366 patients, 97 had positive treadmill tests...

BACKGROUND: Adrenomedullin is a free circulating peptide that regulates endothelial barrier function and vascular tone. Here, we sought to study the relationship of adrenomedullin in combination with lactate and the risk of death in patients with out-of-hospital cardiac arrest (OHCA). METHODS: Mid-regional pro-ADM (MR-proADM) and lactate concentrations were measured in OHCA patients who survived at least 24 h after return of spontaneous circulation. The outcome of interest was all-cause death...

BACKGROUND: High-sensitivity Troponin T (hsTnT), a biomarker of cardiomyocyte overload and injury, relates to aortic valve replacement (AVR) and mortality in severe aortic stenosis (AS). However, its prognostic value remains unknown in asymptomatic patients with AS. We aimed to investigate if an hsTnT level >14 pg/mL (above upper limit of normal 99th percentile) is associated with echocardiographic AS-severity, subsequent AVR, ischaemic coronary events (ICE), and mortality in asymptomatic patients with non-severe AS...

Inflammation is a key determinant of cardiovascular outcomes, but its role in heart failure is uncertain. In patients with cardiometabolic disease enrolled in the prospective, multicenter ancillary study of CIRT (Cardiovascular Inflammation Reduction Trial), CIRT-CFR (Coronary Flow Reserve to Assess Cardiovascular Inflammation), impaired coronary flow reserve was independently associated with increased inflammation and myocardial strain despite well-controlled lipid, glycemic, and hemodynamic profiles. Inflammation modified the relationship between CFR and myocardial strain, disrupting the association between cardiac blood flow and function...

IMPORTANCE: Dapagliflozin reduces the risk of hospitalizations for heart failure and the progression of chronic kidney disease in patients with and without type 2 diabetes (T2D), whereas the effects on reducing atherosclerotic events appear less clear. OBJECTIVE: To explore whether N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hsTnT) levels can identify a subset of patients with T2D at higher risk and who might benefit more from dapagliflozin with regard to atherosclerotic events...

INTRODUCTION: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a progressive disease leading to ventricular arrhythmias and heart failure. Determining optimal time for heart transplantation (HTx) is challenging and finding risk factors for disease progression is needed. OBJECTIVES: The study aimed to identify predictors of end-stage heart failure and evaluate the role of biomarkers in predicting adverse outcomes in ARVC. PATIENTS AND METHODS: Ninety-one patients with ARVC (59 males, mean [SD] age 47 [16] years) were included...

OBJECTIVE: To investigate whether high-sensitivity cardiac troponin T (hsTnT) correlates to markers of disease activity in inflammatory arthritis (IA), and whether antirheumatic treatment influences hsTnT levels. METHODS: We assessed 115 patients with active IA (64 rheumatoid arthritis (RA), 31 psoriatic arthritis and 20 ankylosing spondylitis) before and after using methotrexate (MTX) alone or tumor necrosis factor inhibitor (TNFi) with or without MTX co-medication (TNFi±MTX)...

INTRODUCTION: Catestatin (CST) is a peptide with immunomodulatory, anti-inflammatory, and anti-microbial activities. There are only a few studies that have investigated plasma CST levels in COVID-19 patients (mostly in ICU patients). In our work, the aim was to demonstrate serum CST levels and their correlation with clinical outcomes in a group of severe COVID-19 patients admitted to the non-ICU department. METHODS: The subjects were 32 patients (25 females, 7 males) admitted to the non-ICU unit for COVID-19 patients...

BACKGROUND: Acute pericarditis/myocarditis is a rare complication of the mRNA-based vaccines and although mostly self-limiting, long-term sequelae remain unclear. METHODS: We enrolled all patients admitted to the emergency department between September 2021 and February 2022 meeting the CDC work case definition, with symptoms onset after mRNA-based COVID-19 vaccine. Alternative virologic causes were excluded. Clinical data, laboratory values, cardiologic evaluation, electrocardiogram (ECG), and echocardiogram (ECHO) were collected on admission, at discharge, and during follow-up in all patients...

BACKGROUND: Myocarditis is a dreaded and unpredictable complication of immune checkpoint inhibitors (ICI). We sought to determine whether routinely measured biomarkers could be helpful in monitoring for ICI myocarditis. OBJECTIVES: The authors examined biomarker trends of patients on ICI and their association with the incidence of ICI myocarditis and outcomes. METHODS: We conducted an observational cohort study of adults who received at least one dose of ICI at Michigan Medicine between June 2014 and December 2021 and underwent systematic serial testing for aspartate aminotransferase (AST) and alanine aminotransferase (ALT), creatine phosphokinase (CPK), and lactate dehydrogenase during ICI therapy...

INTRODUCTION: Heart failure patients discharged from the hospital are at high risk of death and rehospitalization. Scarce data are available on the use of sacubitril/valsartan in this population in Poland. OBJECTIVE: To compare the efficacy and tolerability of sacubitril/valsartan in the group of Polish patients who participated in the TRANSITION study with patients recruited at other sites. PATIENTS AND METHODS: This is a post-hoc secondary analysis of the TRANSITION study comparing sacubitril/valsartan initiation pre- vs...
