Temporal Evolution of Serum Concentrations of High‐Sensitivity Cardiac Troponin During 1 Year After Acute Coronary Syndrome Admission

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Detailed insights in temporal evolution of high‐sensitivity cardiac troponin following acute coronary syndrome (ACS) are currently missing. We aimed to describe and compare the post‐ACS kinetics of high‐sensitivity cardiac troponin I (hs‐cTnI)

Spuriously Elevated Cardiac Troponin in the Setting of Atypical Chest Pain Presentation

JACC: Case Reports, 2020
A 47-year-old woman presented with atypical chest pain and a troponin level of 30.15 ng/dl. A detailed diagnostic work-up did not detect an acute myocardial infarction but revealed the presence of heterophile antibodies.

Measurement of Calcium Dissociation Rates from Troponin C in Rigor Skeletal Myofibrils

Frontiers in Physiology, 2011
Ca2+ dissociation from the regulatory domain of troponin C may influence the rate of striated muscle relaxation. However, Ca2+ dissociation from troponin C has not been measured within the geometric and stoichiometric constraints of the muscle fiber ...

Impact of a rapid high‐sensitivity troponin pathway on patient flow in an urban emergency department

Journal of the American College of Emergency Physicians Open, 2022
Study Objective To evaluate whether the introduction of a 1‐hour high‐sensitivity cardiac troponin‐T (hs‐TnT) pathway for patients who present to the emergency department (ED) with suspected acute coronary syndrome (ACS) improves ED patient flow without ...

The rise of Troponin [PDF]

Irish Journal of Medical Science, 2004
In recent years the use of troponin testing to monitor myocardial damage has become more pervasive and prominent, replacing the old style CK-MB measurement. Troponin elevation is a marker of cardiac injury and high risk, it is also raised in a minority of acute coronary syndrome patients. However, it is important for clinicians to realise that a single

Cardiorespiratory evaluation of juvenile rats experimentally envenomed with Tityus serrulatus venom

Journal of Venomous Animals and Toxins including Tropical Diseases, 2010
Accidental envenomation caused by Tityus serrulatus scorpions is very common in Brazil and may result in serious cardiorespiratory alterations that are frequently fatal to children. In the present study, the effects of T.
