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.
