Physical exertion may cause high troponin levels.

It is important to measure troponin levels when acute myocardial infarct is suspected. Many other factors that affect the heart can cause an increase in troponin levels, for example extreme physical exertion. Recent studies have shown that more normal physical activity can also lead to increase in troponin levels in healthy individuals.

Age and gender differences in the association between Nt-proBNP and glucometabolic disturbances.

Objectives: Glucometabolic disturbances are associated with myocardial dysfunction. Brain natriuretic peptides (BNP) are used for detecting myocardial dysfunction in clinical practice. However, studies on elderly subjects and gender-specific analyses are sparse.

Determinants and prognostic implications of cardiac troponin T measured by a sensitive assay in type 2 diabetes mellitus.

Background: The cardiac troponins are biomarkers used for diagnosis of myocardial injury. They are also powerful prognostic markers in many diseases and settings. Recently introduced high-sensitivity assays indicate that chronic cardiac troponin elevations are common in response to cardiovascular (CV) morbidity.

A sensitive cardiac troponin T assay in stable coronary artery disease.

Background: In most patients with stable coronary artery disease, plasma cardiac troponin T levels are below the limit of detection for the conventional assay. The distribution and determinants of very low circulating troponin T levels, as well as their association with cardiovascular events, in such patients are unknown.

Methods: We used a new, high-sensitivity assay to determine the concentration of cardiac troponin T in plasma samples from 3679 patients with stable coronary artery disease and preserved left ventricular function.
