  1. Data are expressed as mean ± standard deviation (SD) or as number (ratio); HR heart rate, LVIDd Left ventricular internal dimension in diastole, RWT Relative wall thickness, LVEDVI Left ventricular end-diastolic volume index, LVMI Left ventricular mass index, LAD Left atrial diameter, LAVI LA volume index, LVEF Left ventricular ejection fraction; the data of normal controls (NC) see Table one; group A, normal LVEF and LV end diastolic volume index, group B, “borderline” LVEF and enlarged LV end diastolic volume index, group C, reduced LVEF (LVEF < 45%). △ p < 0.05 vs NC; ▲ p < 0.05 vs group A; ☆ p < 0.05 group B
