Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The change from baseline in carotid-femoral pulse wave velocity (PWV) [ Time Frame: Up to 1 year of double-blind treatment ]
  2. The change from baseline in carotid-femoral PWV, after adjustment for change from baseline in mean blood pressure (MBP)as measured at the same visit [ Time Frame: Up to 1 year of double-blind treatment ]

Secondary Outcome Measures :
  1. On blood pressure (BP) lowering, assessed by conventional BP measurement and 24h ambulatory BP measurement (24h-ABPM) [ Time Frame: Up to 1 year of double-blind treatment ]
  2. On central pulse pressure (PP) and augmentation index (AI) [ Time Frame: Up to 1 year of double-blind treatment ]
  3. On common carotid stiffness, intima-media thickness (IMT), and internal diameter [ Time Frame: Up to 1 year of double-blind treatment ]
