High-sensitivity cardiac troponin assays are used in the evaluation of patients with suspected acute coronary syndromes in the emergency department (ED), however, these tests are typically laboratory based. In this interview, Dr. Martin Than, Director of Emergency Medicine Research, Christchurch Hospital, New Zealand, discusses the impact that a point-of-care high-sensitivity cardiac troponin assay would have on the ED, the key factors that would need to be considered when introducing this test, as well as its potential impact beyond the ED.
