About this trial

Olive extracts are considered to have antioxidant properties. The investigators will study the effect of olive extracts containing hydroxytyrosol (HT)-olivomed and combination of Oleuropein (OL), Hydroxytyrosol (HT), Oleocanthal (OC) - olivomedSmart on endothelial, cardiac and vascular function in patients with coronary artery disease .

Eligibility criteria

Trial design

Design model

Crossover

Treatments tested in this trial

  • Olivomed (capsules containing hydroxytyrosol)

    Dietary supplement

    patients with stable coronary artery disease will be randomised to Olivomed or placebo for one month and then they will be crossed over to the alternate treatment for one month.

  • OlivomedSmart - Capsules containing - combination of Oleuropein (OL), Hydroxytyrosol (HT), Oleocanthal (OC) - (OL:HT:OC 2:1:3), (5 mg HT bid).

    Dietary supplement

    patients with stable coronary artery disease will be randomised to combination of OL, HT, OC or placebo for one month and then they will be crossed over to the alternate treatment for one month.

Trial outcomes

Primary outcomes

1

Olivomed and OlivomedSmart effects on endothelial glycocalyx thickness.

Olivomed and OlivomedSmart effects on endothelial glycocalyx thickness as assessed by perfused boundary region (PBR, micrometers) of the sublingual arterial microvessels using Sidestream Darkfield (SDF) imaging

Time frame
one month
2

Olivomed and OlivomedSmart effects on endothelial function.

Olivomed and OlivomedSmarteffects on endothelial function. Endothelial function is assessed by measuring Flow Mediated Vasodilation (FMD) of the brachial artery using ultrasonography. During FMD test, vasodilation occurs following an acute increase in blood flow, typically induced via circulatory arrest in the arm (supra-systolic cuff occlusion) for 5 minutes. FMD is the percent of increase of the brachial artery diameter during hyperemia after release of the occlusion.

Time frame
one month
3

Olivomed and OlivomedSmart effects on arterial stiffness

Olivomed and OlivomedSmart effects on on arterial stiffness as assessed by carotid to femoral pulse wave velocity (PWV, m/s) using tonometry.

Time frame
one month
4

Olivomed and OlivomedSmarteffects on coronary function.

Olivomed and OlivomedSmart effects on coronary function as assessed by measuring coronary flow reserve of Left anterior descending artery. Coronary flow reserve is estimated by Doppler echocardiography as the ratio of coronary flow velocity after bolus intravenous adenosine infusion to coronary flow velocity at rest.

Time frame
one month
