Basic Information

Recruitment status Complete: follow-up continuing
Health condition(s) or Problem(s) studiedHypertension with type 2 diabetes mellitus
Date of first enrollment2004/11/01
Target sample size300
Countries of recruitmentJapan
Study typeInterventional
Intervention(s)Maximum dosage of Angiotensin II receptor antagonists (candesartan cilexetil, losartan potassium, telmisartan, valsartan, olmesartan medoxomil) is administered from the beginning of the study (after randomized) over 3 years. Normal dosage of AII antagonists + 5mg of Ca-channel blocker (amlodipine besilate) are administered from the beginning of the study (after randomized) over 3 years.

Outcome(s)

Primary Outcome-Changes in blood pressure level at home after gettin up. -The rate of the blood pressure levels at home after getting up, which effected the target levels(systolic blood pressure < 125mmHg, diastolic blood pressure < 80mmHg).
Secondary Outcome-Changes in blood pressure levels measured on an outpatient basis. -The rate of the blood pressure levels measured on an outpatient basis, which effected the standard levels(systolic blood pressure level < 130mmHg, diastolic blood pressure level < 80mmHg). -Changes in blood pressure levels measured at home before going to bed -Changes in IMT of the cervical artery -Changes in PWV -Changes in echocardiographic findings -Changes in urinary albumin level -Changes in BNP -Changes in hs-CRP -Medical cost-effectiveness -Adverse events, adverse drug reactions -Clinical laboratory data
