High-Sensitivity Troponin I Assay for Differential Diagnosis of New-Onset Myocardial Infarction in Patients with Acute Decompensated Heart Failure.

For diagnosis of suspected NSTEMI in patients with ADHF, initial hS-TnI assay has similar predictive value as ischemic changes on electrocardiogram and superior predictive value than delta hS-TnI calculated by the 0-2-h protocol.
