Olive Oil A
Olive Oil B

Primary Outcome Measures :
  1. Supplementation with enhanced olive oil will improve endothelial function as assessed by the reactive hyperemia peripheral arterial tonometry (RH-PAT) in patients with coronary artery disease (CAD) risk factors and endothelial dysfunction [ Time Frame: Baseline and post 4 month ]

Secondary Outcome Measures :
  1. Supplementation of EGCG enhanced olive oil will reduce peripheral markers of endothelial dysfunction and inflammation, oxidative stress and inflammation [ Time Frame: Baseline and post 4 month ]

Biospecimen Retention:   Samples Without DNA

Study Population
Mayo Clinic Patients

Inclusion Criteria:

  • Patients will be included in the study if they have an abnormal endothelial function study. This is defined at our institution as an RH-PAT index of less than 2. Patients will undergo two RH-PAT analyses and included abnormal values are obtained on either one or both tests. Only patients who provide written informed consent will be included.

Exclusion Criteria:

  • Patients with normal baseline endothelial function studies defined as RH-PAT index >2 will be excluded. Patients with uncontrolled hypertension >180/100 while on medication on initial evaluation will also be excluded.
