  1. Data are represented as mean values ±SD. LVEDD Left Ventricle End Diastolic Diameter, LVESD Left Ventricle End Systolic Diameter, LVEDV Left ventricular end-diastolic volüme, LVESV Left ventricular end-systolic volüme, LAa Left atrial area, LAv Left atrial volume, mm millimeters, bpm beats per minute, Tp-e interval T-peak to T-end interval; c = rate corrected value; B = corrected with Bazett’s formula
  2. AST-ALT-WBC-CRP AND Lymphocyte levels are boldface, because they are significant (p < 0.05)
