Troponin T Test Helps Assess Mortality Risk Following Noncardiac Surgery

A new study in JAMA finds that postoperative troponin T (TnT) tests can independently improve 30-day-mortality risk assessment among patients who have undergone noncardiac surgery. The VISION (Vascular Events in Noncardiac Surgery Patients Cohort Evaluation) study investigators evaluated the prognostic power of postoperative fourth-generation TnT testing in 15,133 patients. Overall mortality at 30 days was 1.9%. Some 11.6% of patients […]

Troponin Elevation in Skeletal Muscle Disease: Vindication for the Consulting Cardiologist?

In an elegant study that will resonate with the anecdotal experience of many consulting cardiologists, Jaffe and colleagues provide strongly suggestive evidence that elevations in “cardiac” troponin T may not be quite as specific for cardiac muscle injury as has been claimed (see CardioExchange News blog). Among patients with skeletal myopathies who had elevations in […]

Study Finds Noncardiac Sources of Positive Troponin T Tests

Cardiac troponin T (cTnT) is not always cardiac specific and in some cases may lead to a false-positive diagnosis of cardiac injury, according to a study in the Journal of the American College of Cardiology. The study was prompted by a case seen by a senior clinician at the Mayo Clinic in which a patient, who was […]
