Content
0.44 -> Like all other tissues in the body, the heart
muscle needs oxygen-rich blood to function.
6.279 -> The coronary arteries, which are wrapped around
the heart, fill that need.
11.3 -> In some conditions, fat can build up along
the walls of the coronary arteries,
16.25 -> reducing the supply of oxygen to the heart muscle.
18.9 -> This build-up is called atherosclerosis.
21.779 -> The 3 major risk factors of atherosclerosis
are high blood pressure, high cholesterol,
27.19 -> and smoking.
29.97 -> This plaque can tear, causing the body's emergency
repair system to rally.
34.94 -> Blood components called platelets stick to
the fat that is now exposed by the tear, forming
39.46 -> a clot.
41.42 -> The clot can completely block the blood supply
downstream to the heart.
49.27 -> Within a few minutes, muscle cells in the
heart begin to die; this is a heart attack.
56.399 -> The heart keeps beating but starts to lose
its normal rhythm.
60.09 -> If a larger part of the heart is affected,
it can stop beating entirely;
64.271 -> this is called a cardiac arrest.
67.34 -> Despite common misconceptions, a guy grabbing
his chest and falling to the ground is not
72.229 -> the typical presentation of a heart attack.
75.229 -> Some people do experience the classic “Hollywood
heart attack”, but the truth is, the symptoms
80.48 -> of a heart attack can be much more subtle.
84.06 -> Many heart attacks begin with only mild discomfort
in the chest that intensifies over time.
90.049 -> Other symptoms include pain in one or both
arms, the neck, or the abdomen.
95.08 -> Shortness of breath may accompany the pain,
along with unexplained sweating.
100.079 -> Time is critical in treating a heart attack;
the condition can be totally reversible if
105.11 -> diagnosed and treated early.
107.56 -> Irreversible damage begins within 30 minutes
of blockage, and half of deaths occur in the
112.78 -> first 4 hours after symptoms begin.
115.85 -> Doctors can perform an angioplasty to reopen
the artery.
119.689 -> Please watch my next video to learn more about
this procedure.
