Primary Outcome Measures:
  • Endothelial function [ Time Frame: 3 months ]
    Endothelial function evaluated by brachial flow-mediated dilation and by peripheral arterial tonometry.

Estimated Enrollment: 52
Study Start Date: May 2011
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Omega-3 fatty acid Dietary Supplement: DHA-EPA
1800 mg/day
Other Name: OMEVITS
Active Comparator: Ciprofibrate Drug: Ciprofibrate
100 mg/day
Other Name: LIPLESS

Detailed Description:
Hypertensive patients aged 40-65 years, both genders, presenting serum triglycerides levels higher than 150 mg/dl will be randomized into two groups. The first group will be receiving ciprofibrate 100mg/day and the second group will be receiving fish oil 1800mg/day. All patients will be evaluated with brachial flow-mediated dilation and with EndoPAT to assess endothelial function before and after supplementation. SPHYGMOCOR and pulse wave velocity (PWV) measurements will also be obtained.
