“…However, like the vast majority of studies that used CTA in the context of hospital ER, their results mostly apply to low-risk populations. 4,5 In this issue of the journal, Matos Soeiro et al 6 publish an interesting study that compares the performance of CTA against the serial assessment of cTnI-hs in 100 patients with chest pain referred to the ER, initially negatives ECG and cTnI-hs and an intermediate TIMI RS. 6 Unsurprisingly, CTA performed better than cTnI-hs measurements in detecting important CAD, with the time interval between patient arrival and CTA being approximately one hour shorter than the interval between patient arrival and the result of the second troponin measurement.…”
