Impact of genotype and phenotype on cardiac biomarkers in patients with transthyretin amyloidosis - Report from the Transthyretin Amyloidosis Outcome Survey (THAOS). [PDF]

PLoS ONE, 2017
AIM:Cardiac troponins and natriuretic peptides are established for risk stratification in light-chain amyloidosis. Data on cardiac biomarkers in transthyretin amyloidosis (ATTR) are lacking.

Hydrodynamic properties of bovine cardiac troponin-I and troponin-T.

Journal of Biological Chemistry, 1983
Bovine cardiac troponin-I (TN-I) and troponin-T (TN-T) have been examined in solution using ultracentrifugation, gel filtration, and viscosity. A new method of purifying TN-T, employing hydroxylapatite chromatography in 6 M urea, is reported. Cardiac TN-T (Mr = 36,000) undergoes a reversible, concentration-dependent association in nondenaturing buffers,

Clinical Utility of Cardiac Troponin I and Cardiac Troponin T Measurements [PDF]

Acta Medica, 1997
The measurement of CK-MB remains the test of choice for confirmation or exclusion of AMI and probably will remain the test of choice for routine diagnosis in the near future.

Half-Life and Clearance of Cardiac Troponin I and Troponin T in Humans. [PDF]

Circulation
BACKGROUND: Cardiac troponin (cTn) is key in diagnosing myocardial infarction (MI). After MI, the clinically observed half-life of cTn has been reported to be 7 to 20 hours, but this estimate reflects the combined elimination and simultaneous release of cTn from cardiomyocytes.

Dephosphorylation specificities of protein phosphatase for cardiac troponin I, troponin T, and sites within troponin T [PDF]

International Journal of Biological Sciences, 2006
Protein dephosphorylation by protein phosphatase 1 (PP1), acting in concert with protein kinase C (PKC) and protein kinase A (PKA), is a pivotal regulatory mechanism of protein phosphorylation.

Myocardial Tissue Characterization in Patients with Hypertensive Crisis, Positive Troponin, and Unobstructed Coronary Arteries: A Cardiovascular Magnetic Resonance-Based Study

Diagnostics, 2023
Hypertensive crisis can present with cardiac troponin elevation and unobstructed coronary arteries. We used cardiac magnetic resonance (CMR) imaging to characterize the myocardial tissue in patients with hypertensive crisis, elevated cardiac troponin ...

Renal Elimination of Troponin T and Troponin I [PDF]

Clinical Chemistry, 2003
Cardiovascular complications represent the predominant cause of death in patients in the terminal stage of renal failure. Increased concentrations of cardiac troponin T (cTnT) may be a valuable predictor of cardiac risk (1)(2). However, cardiac troponin I (cTnI), clinical symptoms, and electrocardiogram (ECG) indications may be absent in patients with ...

The Prognostic Significance of Troponin I and Troponin T [PDF]

Academic Emergency Medicine, 1998
Abstract. Objectives: To determine and compare the prognostic abilities of early, single‐sample measurements of cardiac troponin I (cTn‐I), cardiac troponin T (cTn‐T), creatine kinase‐MB (CK‐MB) among ED patients with possible myocardial ischemia. Methods: Prospective collection of clinical and serologic data using an identity‐unlinked technique from
