Interventions/Control_1

Azelnidipine(8 to 16mg/day) is added in patients with the treatment of the RAS inhibitor.If BP dose not reach to lower than 130/80mmHg, other antihypertensive drug except CCB, diuretic and RAS inhibitor is added.

Interventions/Control_2

Trichlormethiazide(0.5 to 1mg/day) is added in patients with the treatment of the RAS inhibitor. If BP dose not reach to lower than 130/80mmHg, other antihypertensive drug except CCB, diuretic and RAS inhibitor is added.
