Plasmatic apelin shows a promising potential as a screening biomarker for atrial fibrillation.

Objectives: Purpose of this study was to evaluate properties of apelin, a peptide detectable in peripheral blood, for atrial fibrillation (AF) detection in a diverse population of patients covering a broad spectrum from healthy to polymorbid patients.

Background: AF is the most common cardiac arrhythmia with constantly increasing incidence and prevalence. Currently available diagnostic tools do not provide sufficient detection rate.

Lipoprotein profile in patients who survive a stroke.

Objective: In the subjects, who survived a stroke, an atherogenic lipoprotein profile phenotype B, was identified and a predominance of atherogenic lipoproteins of the lipoprotein families, VLDL and LDL, in the lipoprotein spectrum, was confirmed. The higher total cholesterol, triglycerides, and low HDL concentrations were accompanied by high serum levels of small dense LDL - strong atherogenic subfractions of the LDL family. High LDL2 also contributes to the creation of the atherogenic lipoprotein profile.
