Do high-sensitivity cardiac troponins I and T provide comparable prognostic information for stroke and cardiovascular events in patients with atrial fibrillation?
High-sensitivity cardiac troponins I and T offer comparable and additive prognostic value for predicting stroke and cardiovascular events in patients with atrial fibrillation.
cTnI and cTnT concentrations are moderately correlated and measurable in plasma of most AF patients. The risk of stroke and cardiovascular events is highest when both troponins are above median concentrations. Each troponin provides comparable prognostic information when combined with clinical risk factors. ClinicalTrials.gov/NCT00412984.
