Biochemical Assays
High sensitive Tn-T measurements were conducted with Elecsys Troponin T
hs STAT kits (Roche Diagnostics GmbH, Mannheim, Germany). High sensitive
troponin-T is regarded as positive when ≥14 ng/l, according to the
manufacturer’s indications and guidelines 3. Copeptin
levels were measured using the serum samples taken during the hospital
admission process and preserved under the manufacturer’s recommended
conditions. Copeptin measurements were performed using the BRAHMS
Copeptin KRYPTOR assay on a BRAHMS KRYPTOR compact plus analyzer (BRAHMS
GmbH, Hennigsdorf, Germany). Copeptin is regarded as positive when
>17.4 pmol/l, as per the manufacturer’s guidelines.
