Abstract
This study was designed to compare cTnI levels determined with an Access II assay and an Immulite system in patients with high risk for CAD. CTnIc were determined in 74 patients admitted to emergency unit for acute chest pain (group I), 34 patients submitted to surgical intervention for distal arteriopathy (group II) and 39 Type II diabetes mellitus (group III) with more than two other risk factors. Despite comparable analytical performances, discrepancies between cTnI levels are observed concerning myocardial infarction threshold value (5/147 determinations), 99th percentile (29/147 determinations) and functional sensitivity (6/147 determinations). Functional sensitivity could be an optional threshold value to rule out the presence of circulating CtnI.
