How Arteries Get Clogged

Coronary artery disease (CAD) is the most common heart disease to watch out for.

CAD occurs when the arteries feeding the heart get clogged up.
As a result, blood flow to the heart is restricted.
This deprives the heart muscle of the oxygen it needs to function.
Arterial clogging happens due to atherosclerosis, a natural ageing process that begins in late childhood. An unhealthy lifestyle, bad eating habits and a lack of physical activity can accelerate atherosclerosis.

EVER SEEN A CLOGGED ARTERY?

1)

   A normal arthery: LDL-cholesterol enters inner artery wall where they become
   oxidised.

2)

    Monocytes penetrate the inner artery wall and become macrophages which
    devour oxidised LDL-cholesterol to form foam cells.

3)

    Formation of a lipid core stimulates the release of substances
    (called growth factors) which attracts smooth muscle cells to form afibrous cap.

4)

    The lipid core ruptures and causes formation of a blood clot whitch blocks blood
    flow.
