Elevated troponin levels identified individuals at risk of microvascular obstruction and mortality after myocardial ...

Myocardial infarction can only be diagnosed when cardiac troponin I or T are increased in the clinical setting of myocardial ischemia – this means the myocardial cells suffer from a lack of ...

Patients who are hospitalized for either viral infection should be screened for myocardial involvement, experts say.

Troponin is a widely used biomarker in patients with cardiac disease. The use of troponin is well established in patients with suspected acute myocardial infarction (AMI), but troponin measurement ...

Finally, elevations of troponin (>5 times the URL) can be used in the diagnosis of a type 5 myocardial infarction, i.e., an infarct associated with coronary bypass surgery (Thygesen et al, 2007 ...

Results showed that inducible myocardial ischemia (NPV = 90%; 95% CI, 83-95) was present in 10 of 101 patients in the derivation cohort with an hscTnI level below 2.5 pg/mL.

"Using the [standard] troponin I assay with a threshold of 50 ng/L, 55 women (11%) and 117 men (19%) were classified as having type-1 myocardial infarction," according to the investigators ...

Using sex-specific thresholds with high-sensitivity troponin testing for suspected ACS leads to a disproportionately greater increase in the number of women versus men found to have some degree of ...

Comparatively, CoDE-ACS ruled out myocardial infarction, even in early presenters, using a single cardiac troponin test, thereby reducing the damage due to nonadherence with the measurement timing.
