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.

  1. Well I was at football practice we were training very intensely and i happened to have a lot of heart pain. Is that a sign of a heart attack or just working too hard. Or both

  2. I'm really amazed by the animations and creativity as well as the coherence and cohesion presented in every educational videos by TED. They're all very helpful and very informative even to someone like me who's already working in the healthcare delivery, i am still stunned just like a kid who had her first lesson learned every time i watch TED-Ed clips. Please keep on producing more educational vids like this!

  4. Weird how diet is a factor, 2016 the week of Christmas I had a heart attack at work. I was only 40 years old, the pain started in my back migrated to the front center of my chest. The best description is it did feel like a vice was squeezing my heart. I do have heart disease but I have been a vegetarian since I was twelve and I had converted to a vegan just five years before the heart attack. 🤷🏻‍♀️ genetics well yes must be the largest factor here I suppose.

  6. How much Aspirin should be given incase of emergency? And can we give aspirin without confirming the heart​ attack by a professional?

  7. None of the remedies is any good. The plaque is the bodies way of putting a bandaid over an area of inflammation. The inflammation is due to damage to the endothelia caused by grain and seed oils, sugar, refined carbs, smoke. American medical practice treats symptoms, ignores causation.
