[Determinants of elevation of high sensitivity cardiac troponin T after an atrial septal defect percutaneous closure].
Arch Cardiol Mex
March 2025
Servicio de Pediatría, Hospital Privado Universitario de Córdoba. Córdoba, Argentina.
Objectives: The aim was to determine the relationship between the elevation of ultrasensitive troponin T (hs-cTnT) after percutaneous atrial septal defect (ASD) closure with deficient aortic rim and with standard and specific maneuvers of the intervention.
Method: Baseline hs-cTnT was measured and repeated 6 hours after the procedure. To determine the influence of independent variables with the dependent variable (change in hs-cTnT), a generalized linear mixed model was used.
Myocardial T1 Mapping, Left Ventricular Parameters, and Cardiac Biomarkers in Wild-Type Transthyretin Amyloid Cardiomyopathy Before and After Tafamidis Treatment.

Background: To further elucidate the clinical implications of myocardial T1 mapping with cardiac magnetic resonance (CMR) in transthyretin amyloid cardiomyopathy (ATTR-CM), we investigated the relationships of native myocardial T1 value (T1) and extracellular volume fraction (ECV) with left ventricular (LV) parameters and cardiac biomarkers in ATTR-CM patients before and after tafamidis treatment.
Methods And Results: We studied wild-type ATTR-CM patients who underwent baseline CMR with LV cine and T1 mapping techniques. T1 and ECV were derived from averaged values of base-to-apex LV myocardium.
Targeted heart rate control using the funny current inhibitor ivabradine to reduce morbidity in patients undergoing noncardiac surgery: study protocol for a phase 2a, triple-blind, placebo-controlled randomised trial.

Background: Myocardial injury is strongly associated with excess morbidity and mortality after noncardiac surgery. Higher heart rate may result in perioperative myocardial injury through demand-supply mismatch. Alternatively, higher heart rates may reflect autonomic dysfunction that promotes myocardial injury independently of heart rate.

Chest pain is one of the most common presenting complaints to emergency departments in the United States, and management centers on identifying myocardial infarction or other forms of rare but problematic cardiac diagnoses. The high-sensitivity troponin assay can detect abnormal troponin elevations at 10- to 100-fold lower levels compared with traditional troponin assays and thus can allow faster time to disposition and diagnosis, yet adoption has not been universal. Implementing a high-sensitivity troponin protocol with a risk prediction algorithm can decrease the numbers of patients admitted, reduce unnecessary testing, and shorten patient stays in the emergency department.

This pilot study evaluates the efficacy, feasibility, and precision of the QuidelOrtho TriageTrue hs-cTnI POC assay when used by non-laboratory personnel in emergency primary care. Methods A prospective pilot study was conducted from April to June 2024 at the main emergency primary care clinic in Oslo, Norway.
