Prediction of Primary Cardiovascular Events Using the Multimarker Approach

All patients were tested for glucose and cholesterol levels. The capillary blood glucose level was measured by an electrochemical method using an Accu-Chek Active by AkkuChek blood glucose meter. The DM was considered to be verified when there were criteria which the World Health Organization (WHO) set in 2001: glucose concentration in whole blood is \>6.1 mmol/l, and glucose concentration is \>11.1 mmol/l in random measurement. Plasma for the study was obtained via the standard phlebotomy technique from ethylenediaminetetraacetic acid (EDTA) anticoagulants. Plasma was aliquoted into cryovials and got frozen quickly. The samples were stored in a low-temperature refrigerator (-70°C) until the study commencement (up to 3 months). All biomarkers were measured by magnetic bead-based multiplex immunofluorescence assay through the Xmap technology using the Milliplex map Human CVD Magnetic Bead Panel 1 (Millipore)
