Acute Coronary Syndrome and Heart Attack
Acute Coronary Syndrome and Heart Attack
http://www.nucleushealth.com/ - This 3D medical animation shows the coronary vessels in the heart and the different ways they may become blocked. The symptoms of acute coronary syndrome (ACS) are depicted. The animation finishes up with common treatments for acute coronary syndrome and heart attack.

12 -> If you have acute
coronary syndrome,
14.92 -> you have one or more
conditions caused
17.35 -> by a blockage of blood
flow to your heart muscle.
21.4 -> This is a medical
emergency, because you
23.64 -> may be having a heart attack,
a condition in which your heart
27.1 -> muscle begins to die.
29.77 -> Your heart is a
muscular organ that
32.14 -> pumps blood
containing the oxygen
34.5 -> and nutrients your body needs.
37.41 -> The main pumping chamber of your
heart is the left ventricle.
41.79 -> When your left
ventricle contracts,
44.09 -> it sends oxygen-rich
blood to your body
46.93 -> through a large artery
called the aorta.
50.59 -> Connected to your aorta
are small arteries
53.59 -> called coronary arteries.
56.34 -> Blood flows from your aorta,
through the coronary arteries,
59.99 -> to supply your heart muscle
with oxygen and nutrients.
64.09 -> If you have acute
coronary syndrome,
66.88 -> blood flow through
your coronary arteries
69.3 -> is severely reduced
or completely blocked.
73.93 -> One possible cause of reduced
blood flow is atherosclerosis.
79.78 -> In this condition, a
build-up of a fatty substance
83.14 -> called plaque can narrow
your coronary arteries.
87.6 -> If this plaque
ruptures, a blood clot
90.24 -> can form and block the artery.
93.18 -> A blood clot is the
most common cause
95.53 -> of coronary artery blockage.
99.03 -> Other, less common causes
of reduced blood flow
102.09 -> include coronary artery
spasm or dissection.
107.82 -> In a coronary artery
spasm, triggers
110.72 -> such as drugs, smoking, cold
weather, and extreme stress
115.86 -> or emotions can cause a
temporary and sudden tightening
120.29 -> of a coronary artery.
121.495 ->
124.64 -> During a coronary
artery dissection,
127.17 -> the inside wall of one
of your coronary arteries
130.08 -> separates, which can
block blood flow.
132.555 ->
136.11 -> Regardless of the
cause, a blockage
138.41 -> in either coronary
artery prevents
140.66 -> the oxygen and
nutrients in your blood
143.09 -> from reaching the part of your
heart supplied by the artery.
147.54 -> As a result, heart muscle
in that area starts to die.
152.6 -> Death of part of
your heart muscle
154.63 -> is called a heart attack.
156.66 -> It's also known as a
myocardial infarction or MI.
162.24 -> A blocked coronary
artery may also
164.51 -> cause you to feel sudden
pain, discomfort, tightening,
169.77 -> or a burning sensation in
your chest called angina.
174.88 -> This pain may extend to your
upper abdomen, shoulders, arms,
180.32 -> neck, and lower jaw.
182.065 ->
185.16 -> If you have angina
when you're at rest,
187.71 -> or frequent angina
that prevents even
190.1 -> moderate physical activity,
you have unstable angina,
194.35 -> which is the main symptom
of acute coronary syndrome.
197.305 ->
200.25 -> Other symptoms of
acute coronary syndrome
202.89 -> include shortness of
breath, dizziness, nausea,
208.89 -> and sweating.
209.56 ->
212.78 -> If you've had a
heart attack or have
214.98 -> other types of acute
coronary syndrome,
217.81 -> your doctor may
prescribe oxygen therapy
220.63 -> to get more oxygen
into your blood.
222.855 ->
225.36 -> You may take aspirin or other
prescription blood-thinner
228.55 -> drugs to prevent blood clots.
232.51 -> Thrombolytics also known
as clot-buster drugs,
236.26 -> may be used to break up
any existing blood clots.
239.435 ->
243.43 -> Drugs such as
nitroglycerin and morphine
246.7 -> will relax your
coronary arteries
249.04 -> and relieve the pain of angina.
250.895 ->
255.87 -> You may also receive drugs
called beta blockers that
259.11 -> slow down your heart and
reduce its need for oxygen.
262.27 ->
266.43 -> Your doctor may also recommend
immediate surgical procedures,
270.31 -> such as coronary angioplasty, in
which a balloon-tipped catheter
274.9 -> inflates inside your blocked
coronary artery to open it.
279.41 ->
281.76 -> may leave behind a mesh-like
device called a stent
286 ->
287.3 -> After inflating, the balloon catheter
may leave behind
290.7 -> a mesh-like device called a stent
to hold your artery open.
299.9 -> Or you may have a coronary
artery bypass graft, or CABG.
305.2 -> CABG is a surgical
procedure in which the blocked
308.99 -> areas of the coronary arteries
311.4 -> are bypassed with veins or
artificial graft material.
317.2 -> Seek treatment
immediately if you
319.9 -> have the symptoms of
acute coronary syndrome.
