Elevated hs-cTnT signals higher 360-day risk after AMI rule-out; leaves open whether targeted follow-up improves outcomes.
Does increased hs-cTnT predict mortality and AMI in ED patients with acute chest pain discharged after AMI rule-out?
In low-risk ED patients discharged after AMI rule-out, mildly increased hs-cTnT is a strong prognosticator of intermediate and long-term mortality and AMI, suggesting a need for further outpatient investigation.
