Data are given in mean numbers unless indicated otherwise; ± indicates one SD, % indicates percentage of that group.
RAS, renal artery stenosis; BMI, body mass index; LDL, low density lipoprotein; HDL, high density lipoprotein; AASI, ambulatory arterial stiffness index; bpm, beats per minute.
Creatinine clearance was calculated by the Cockroft–Gault formula.
