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.
