入选标准
- •Male and female outpatients
- •Age greater than or equal to 18 years and less than or equal to 75 years
- •Hypertension and metabolic syndrome defined, according to the ATP III/IDF 2005 and ESH/ESC 2007 definitions, as BP greater than or equal to 130/85 mmHg and <150/95 mmHg (i.e. untreated high normal BP or "low range" mild hypertension) and at least 2 of the following traits at:
- •Abdominal obesity (waist circumference >102 cm for men and >88 cm for women)
- •Triglyceride level greater than or equal to 150 mg/dL
- •High density lipoprotein (HDL) <40 mg/dL for men and <50 mg/dL for women
- •Fasting blood glucose greater than or equal to 110 mg/dL and <126 mg/dL (i.e. no type 2 diabetes)
- •No anti-hypertensive treatment or treatment with only one anti-hypertensive medication within the last 3 months. Note: treatment with angiotensin II receptor blockers (ARB)or angiotensin-converting enzyme inhibitors (ACE) is not allowed within the last 6 months.
排除标准
- •Pregnant or lactating female (prerequisite for female subjects of childbearing potential: adequate contraception)
- •Type 1 and type 2 diabetes
- •"High range" mild hypertension (i.e. systolic blood pressure [SBP]: 150 - <160 mmHg and /or diastolic blood pressure [DBP]: 95 - <100 mmHg)
- •Moderate (SBP: 160 - 179 mmHg and DBP: 100 - 109 mmHg), severe (SBP: greater than or equal to 180 mmHg and/or greater than or equal to 110 mmHg), or resistant (hypertension resistant to treatment)hypertension
- •Secondary hypertension of any aetiology, such as renal disease, pheochromocytoma, or Cushing's syndrome
