What happens during a heart attack? – Krishna Sudhir


Approximately 7 million people around the
world die from heart attacks every year, and cardiovascular disease, which causes heart attacks and other
problems like strokes, is the world’s leading killer. So what causes a heart attack? Like all muscles, the heart needs oxygen, and during a heart attack,
it can’t get enough. Fatty deposits, or plaques, develop on the walls
of our coronary arteries. Those are the vessels that supply
oxygenated blood to the heart. These plaques grow as we age, sometimes getting chunky, hardened, or enflamed. Eventually, the plaques can turn
into blockages. If one of the plaques ruptures or cracks, a blood clot will form around it
in minutes, and a partially closed artery
can become completely blocked. Blood flow is cut off
to the cardiac muscle and the oxygen-starved cells start to die
within several minutes. This is a myocardial infarction, or heart attack. Things can rapidly deteriorate
in the absence of treatment. The injured muscle may not be able
to pump blood as well, and its rhythm might be thrown off. In the worst case scenario,
a heart attack can cause sudden death. And how do you know that someone
is having a heart attack? The most common symptom is chest pain caused by the oxygen-deprived
heart muscle. Patients describe it as crushing
or vice-like. It can radiate to the left arm, jaw, back, or abdomen. But it’s not always as sudden and dramatic
as it is in the movies. Some people experience nausea or shortness of breath. Symptoms may be less prominent
in women and the elderly. For them, weakness and tiredness
may be the main signal. And surprisingly, in many people, especially those with diabetes,
which affects the nerves that carry pain, a heart attack may be silent. If you think that someone might be
having a heart attack, the most important thing
is to respond quickly. If you have access to emergency medical
services, call them. They’re the fastest way
to get to a hospital. Taking aspirin, which thins the blood, and nitroglycerin,
which opens up the artery, can help keep the heart attack
from getting worse. In the emergency room,
doctors can diagnose a heart attack. They commonly use an electrocardiogram to measure the heart’s
electrical activity and a blood test to assess
heart muscle damage. The patient is then taken to a high-tech
cardiac suite where tests are done
to locate the blockages. Cardiologists can reopen
the blocked artery by inflating it with a balloon
in a procedure called an angioplasty. Frequently, they also insert a metal
or polymer stent that will hold the artery open. More extensive blockages might require
coronary artery bypass surgery. Using a piece of vein or artery
from another part of the body, heart surgeons can reroute blood flow
around the blockage. These procedures reestablish circulation
to the cardiac muscle, restoring heart function. Heart attack treatment is advancing, but prevention is vital. Genetics and lifestyle factors
both affect your risk. And the good news is that you can
change your lifestyle. Exercise, a healthy diet,
and weight loss all lower the risk of heart attacks, whether you’ve had one before or not. Doctors recommend exercising
a few times a week, doing both aerobic activity
and strength training. A heart-healthy diet is low
in sugar and saturated fats, which are both linked to heart disease. So what should you eat? Lots of fiber from vegetables, chicken and fish instead of red meat, whole grains and nuts like walnuts
and almonds all seem to be beneficial. A good diet and exercise plan can also
keep your weight in a healthy range, which will lower
your heart attack risk as well. And of course, medications can also
help prevent heart attacks. Doctors often prescribe low-dose
aspirin, for example, particularly for patients who’ve
already had a heart attack and for those known to be
at high risk. And drugs that help manage risk factors, like high blood pressure, cholesterol,
and diabetes, will make heart attacks less likely, too. Heart attacks may be common,
but they don’t have to be inevitable. A healthy diet, avoiding tobacco use, staying fit, and enjoying plenty of sleep
and lots of laughter all go a long way in making sure
your body’s most important muscle keeps on beating.

  9. I worry about a heart attack mostly because it would increase my risk of a stroke which can cripple a person. I have been a caretaker for my mother for ten years since her stroke. If I must have a heart attack it better finish me off.

  11. I had a heart attack at 35 years of age.. I'm 36 💔 it was so painful like you got stabbed in the middle of the chest, the doctors pushed a stent in one of the coronary arteries, it was bad.

  12. 1:38 I have a question: Why does heart attack can "make us hurt" other part of the body such as our arm, back etc etc?

  13. As someone who has experienced it second hand, I can confirm this random guy on the internet, my grandmother had a heart attack while driving, and only figured out she had one when she broke something and went in to the doctor's

  14. This video made a statement that is false. Sugar DOES promote heart disease. The statement that saturated fats promote heart disease is disproved medical dogma. The so-called French paradox was never a paradox. It was simply proof that saturated fats DON'T cause heart disease.

  15. Always carry with you two tables of asperin and check your cholesterol levels at least two times a year!

  18. Ted: A heart attack can and has been known to cause sudden / instant death in worst case scenarios.

    Ted: A heart attack can and has been known to be silent.

    Ted, a few seconds later: *If you spot any of the symptoms, dial the emergency number.*

  19. My great grandfather died of a heart attack on his 74th birthday on June 21, 2005. His heart attack was sudden death for him, he was dead instantly. My great grandmother who was 75 at the time, she was older, she witnessed my great grandfather die of a sudden death heart attack right in front of her eyes, my great grandfather was starting the car to get ready to go to a kemo therapy meeting, because he was recently diagnosed with cancer. And while my great grandmother was hooking up my great grandfathers oxygen tank, she heard him shout her name in a blood curdling scream and, he just died instantly. And my great grandmother died 6 years later after my great grandfather died in 2005. She died on December 30, 2011 at the age of 81. And, I'm just hoping heart problems don't catch up to me this fast, I'm only 17 and I know my whole family genetically have heart problems. Including my mom. She had to get a 6 way bypass surgery done on March 15, 2007 when she was 34, and now she's 47, and still goes through all these heart problems.

  20. Well I'm boned then. Barely get 2 hours at most sleep every night and already have irregular heartbeats and rates. So I'm a ticking time bomb lol
