The Solution Structure of a Cardiac Troponin C−Troponin I−Troponin T Complex Shows a Somewhat Compact Troponin C Interacting with an Extended Troponin I−Troponin T Component [PDF]

open access: yesBiochemistry, 2002
We have investigated the structure of the cTnC-cTnI-cTnT(198-298) calcium-saturated, ternary cardiac troponin complex by small-angle scattering with contrast variation. Shape restoration was also applied to the scattering information resulting from the deuterated cTnC subunit, the unlabeled cTnI-cTnT(198-298) subunits, and the entire complex.

Investigating the role of uncoupling of troponin I phosphorylation from changes in myofibrillar Ca(2+)-sensitivity in the pathogenesis of cardiomyopathy. [PDF]

open access: yes, 2014
Contraction in the mammalian heart is controlled by the intracellular Ca2+ concentration as it is in all striated muscle, but the heart has an additional signalling system that comes into play to increase heart rate and cardiac output during exercise or ...

Financial impact of a targeted reduction in cardiac enzyme testing at a community hospital [PDF]

open access: yesJournal of Community Hospital Internal Medicine Perspectives, 2016
Objectives: Nearly one-third of healthcare costs are potentially avoidable and would not compromise medical care if eliminated. Therefore, we sought to evaluate the financial impact of reduction in use of creatinine kinase (CK)-MB and myoglobin tests ...

Mountain Ultra-Marathon (UTMB) Impact on Usual and Emerging Cardiac Biomarkers

open access: yesFrontiers in Cardiovascular Medicine, 2022
The number of participants in ultra-marathons is increasing. However, the data regarding the impact of this type of exercise on the cardiovascular system are contradictory. In our study, 28 ultra-trail runners were enrolled.

Which diagnostic tests are most useful in a chest pain unit protocol? [PDF]

open access: yes, 2005
Background The chest pain unit (CPU) provides rapid diagnostic assessment for patients with acute, undifferentiated chest pain, using a combination of electrocardiographic (ECG) recording, biochemical markers and provocative cardiac testing.

High‐Sensitivity Troponin I Levels and Coronary Artery Disease Severity, Progression, and Long‐Term Outcomes

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundThe associations between high‐sensitivity troponin I (hsTnI) levels and coronary artery disease (CAD) severity and progression remain unclear.

Relationship Between Peak Troponin Values and Long‐Term Ischemic Events Among Medically Managed Patients With Acute Coronary Syndromes

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundThe relationship between troponin level and outcomes among patients with non‐ST‐segment elevation ACS is established, but the relationship of troponin level with long‐term outcomes among medically managed non‐ST‐segment elevation ACS patients ...

High-sensitivity troponin assays for early rule-out of acute myocardial infarction in people with acute chest pain: a systematic review and economic evaluation

open access: yesHealth Technology Assessment, 2021
Background: Early diagnosis of acute myocardial infarction is important, but only 20% of emergency admissions for chest pain will actually have an acute myocardial infarction.

A comparison of homocysteine, troponin, cobalamin and folate status in acute myocardial infarction patients and healthy subjects: A case–control study

open access: yesAdvances in Human Biology, 2021
Introduction: Homocysteine (HCY), troponin, cardiac markers, folic acid and Vitamin B12 are known as the potential biomarkers for acute myocardial infarction (AMI) diagnosis.
