theory!

The various stages of plaque development

and when to interfere

Sequence of atherosclerotic process

Normal vessel appearance Early plaque Obstructive plaque Plaque rupture

Endothelial dysfunction

begins

Plaques increase in

number and size

Unstable angina

Non-invasive tests normal Invasive tests abnormal

Acute myocardial infarction -

Cardiac failure

Sudden death

Level of vascular inflammation indicators (VCam, Ecam, MCP-1, MIF, IL-6, ox-LDL, CRP?)

gradually rising as severity of disease increases

So begin treatment HERE!

In certain regions of France, good food and wine,

elsewhere in Western World, Fastfood and sweet drinks.

It shows in longevity!

Jean vs. Joe

6 glasses of a specific* red wine (~280ml) = 500 à 1000mg polyphenols are needed for daily dose

*) Château Petrus… = EXPENSIVE!

` …or 2 capsules? IT IS YOUR CHOICE!

Resveratrol, one of the polyphenols can avoid lesion development as effective as

atorvastatin

THE MAIN CHARACTERISTICS

Food supplements play a significant role next to

general lifestyle changes.

Smoking / Inflammation / Dyslipidaemia / Hypertension / Dysglycaemia

Proinflammatory cytokines which ultimately lead to atherosclerosis (e.g. Vcam, Ecam, MCP-1, MIF, IL-6, TNFα, CD40L, CRP)

No smoking, physical activity 5x week

Red fruits, nuts, vegetables 600gr per day

Oily fish 3x week or 6:1 EPA/DHAOlive oil 4 tblsp/day

or oleuropein+hydroxyl tyrosol

Red wine 4 glasses day or 500mgm In Vino Veritas

A MULTIFACTORIAL DISEASE DESERVES A MULTIFACTORIAL SOLUTION

So, strictly adhere to the Mediterranean Diet or supplement a varied diet with food medicines such as polyphenols and PUFA’s. EHJ 2010, Oxf. Univ. Press

So

And dark chocolate?

Let food be the medicine
