Results are shown as mean ± SD or percentage of subjects. BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; PP: pulse pressure; GFR: glomerular filtration rate; EF: ejection fraction; E: maximal early mitral valve inflow; A: maximal late mitral valve inflow; LVMI: left ventricular mass index. a P < 0.05; b P < 0.01.
