Baseline characteristics of patients were recorded at entrance: age, sex, body-mass index, heart rate, blood pressure, and smoking status (never, former/current). Comorbidities were also recorded: hypertension, diabetes mellitus (DM), atrial fibrillation (AF), stable coronary artery disease, cerebral infarction, chronic kidney disease (CKD), and COPD. Blood biochemistry was assessed from fasting blood samples drawn on the day after entrance, when patients had been on an absolute diet for >12 hours: hemoglobin (Hb), ALT, estimated glomerular filtration rate (eGFR), total cholesterol (TC), triglycerides (TG), high-density-lipoprotein cholesterol (HDL-C), and low-density lipoprotein-cholesterol (LDL-C). eGFR was calculated based on the formula eGFR 175 × (serum creatinine/88.4) − 1.234 × (age) − 0.179 (female × 0.79),5 (link) and eGFR <60 mL/min⋅1.73 m2 was considered decreased renal function.
hs-cTnT concentration was measured using an Elecsys Troponin T Stat immunoassay, while NT-proBNP concentration was determined on an Elecsys proBNP II (Roche Diagnostics). Both analyses were performed at the laboratory of our hospital using automatic analyzers according to recommendations from the manufacturer.
