Join Drs. Lauren Rosenfeld and Dr. Arman Hussain cut through the confusion surrounding high sensitivity troponin (hs-Tn) in the Emergency Department. They break down what this cardiac injury marker actually measures, why the new assays allow for faster ACS screening (often in 1–2 hours) at the cost of more "false positives," and the practical application of 0/1h and 0/2h algorithms. They also dive into key pitfalls, including why cutoffs vary between hospitals, how to approach special populations like those with CKD.
