0.38 -> This animation will show how atherosclerosis
develops in the heart.
5.55 -> Click the navigation arrows below the animation
screen to play, pause, rewind or
11.269 -> fast-forward the animation. This animation
contains sound.
17.21 -> Atherosclerosis is the process by which arteries
become gradually narrowed and
21.759 -> hardened.
If this happens in the arteries that supply
29.558 -> The network of blood vessels that branch over
the surface of the heart are called
33.848 -> the coronary arteries.
Atherosclerosis can happen in any part of
38.908 -> the coronary arteries.
The coronary arteries supply the heart with
43.858 -> blood.
Over years, fatty deposits in the blood can
49.178 -> build up and form a plaque (atheroma)
on the artery wall.
54.728 -> This can prevent the heart muscle from getting
the blood (and the oxygen) supply
59.628 -> that it needs.
This tends to happen during physical exertion
64.388 -> or when angry or stressed.
It causes a heavy or tight chest pain called
70.537 -> angina.
Afterwards the pain goes away.
75.587 -> If the plaque continues to grow, the risk
of having a heart attack, where the blood
80.297 -> supply to the heart is completely cut off,
rises.
85.117 -> This is the end of the animation.
