Primary

MeasureTime frame
The effects of ARBs on the parameters listed below at baseline, 3, 6, and 12 months after the administrations. (1) Blood samples (lipid profiles, glucose tolerance, high-sensitive CRP, BNP, etc.) (2) Oxidative stress marker (8-OHdG, 8-isoprostane, etc.) (3) Electrocardiography (4) Echocardiography (5) Carotid ultrasonography (6) Pulse wave velocity

Secondary

MeasureTime frame
