Table 5 Rates of intervention including PCI and CABG in NSTEMI patients with final diagnosis after the first versus the second cTn control

From: How rapid is rapid? Exemplary results of real-life rapid rule-out troponin timing in troponin-positive acute coronary syndromes without persistent ST-segment elevation in two contrasting German chest pain unit facilities
