Abbott Announces New Data on High-Sensitive Troponin Test Shows Could Help Docs Predict Heart Attack Risk

Abbott ABT announced today promising results from a study evaluating its High Sensitive Troponin-I (hsTnI) assay presented at this year's American Association for Clinical Chemistry (AACC) annual meeting in Houston, Texas. The study, conducted by researchers at Brigham and Women's Hospital, demonstrated that Abbott's hsTnI test (currently for research-use only in the United States) may help doctors predict which patients presenting with symptoms of a heart attack, such as severe chest pain, are at a higher risk for having a heart attack 30 days later. A concern for patients who present with severe chest pain is that they are more likely to experience another cardiovascular event within a few weeks or months. Researchers at Brigham and Women's Hospital evaluated the performance of a hsTnI assay (Abbott, ARCHITECT) with the performance of a fourth generation troponin T assay (Roche, TnT) among 4,695 patients presenting with severe chest pain and found that the hsTnI assay identified more patients at higher risk of recurrent heart attack, even at very low troponin concentrations.
