What Causes Heart Attack? | How to Keep Your Heart Healthy? | Heart Attack Signs and Symptoms

Summary

A heart attack occurs when fatty deposits block the coronary arteries, preventing oxygenated blood from reaching the heart muscle. This causes cells to die. Signs include chest pain, shortness of breath, nausea. High blood pressure, cholesterol, smoking raise risk. If blockage is found through ECG and blood tests, an angioplasty can open the artery. Bypass surgery also an option. Lifestyle changes like healthy eating, exercise and managing stress vital to prevention. Heart attacks can even happen without symptoms, called a 'silent heart attack'.

Takeaways

• 😢 A heart attack can be fatal, claiming around 7 million lives worldwide every year
• ❤️ The heart needs a constant supply of oxygenated blood from the coronary arteries
• 🧠 Fatty deposits in arteries can harden and inflame, causing partial blockages
• 💉 Ruptured blockages trigger blood clotting, blocking arteries entirely
• 😵 Without blood flow, heart muscle cells die, leading to a heart attack
• 🚑 Crushing chest pain, arm/jaw pain are signs of a heart attack and require immediate medical care
• 🚬 High blood pressure, cholesterol, smoking, obesity raise heart attack risk
• 🩺 Doctors can use ECGs, blood tests, angioplasty, or bypass surgery to treat blockages
• 🍎 Healthy lifestyle changes like diet, exercise can significantly lower risk
• 😮 A 'silent' heart attack causes 1 in 5 attacks, with no obvious symptoms initially

Q & A

What are the main causes of plaque buildup in coronary arteries?

High cholesterol, smoking, diabetes, being overweight, and lack of physical activity can cause fatty deposits and plaque to build up in coronary arteries over time.

How does a heart attack occur?

If the plaque buildup in a coronary artery ruptures, it triggers blood clotting. This can fully block the artery, cutting off oxygen to parts of the heart muscle, causing cells to die - resulting in a heart attack.

What are the most common signs and symptoms of a heart attack?

Crushing chest pain, pain in the left arm, neck, jaw or back, shortness of breath, cold sweats, nausea, lightheadedness. Women and older people may experience extreme fatigue and weakness.

What is the medical term for a heart attack?

The medical term for a heart attack is myocardial infarction. This refers to the death of heart muscle cells due to a blocked coronary artery cutting off the blood and oxygen supply.

What emergency medical tests help diagnose a heart attack?

An electrocardiogram (ECG) can check the heart's electrical activity. A blood test looks for signs of heart muscle damage. These tests help doctors urgently diagnose a heart attack.

How can doctors treat a heart attack?

Emergency treatments include angioplasty to open blocked arteries or bypass surgery to redirect blood flow. These restore oxygen supply to save dying heart muscle.

What lifestyle changes can prevent heart attacks?

Eating healthy foods, regular exercise, avoiding smoking, getting enough sleep, and managing stress can significantly lower heart attack risk.

What are silent heart attacks?

Silent heart attacks have no obvious symptoms but still damage heart muscle. 1 in 5 attacks are 'silent', highlighting the need for regular checkups.

Why is fast treatment essential in a heart attack?

Rapid treatment is vital because without oxygen, heart muscle cells start dying within minutes. Fast restoration of blood flow limits permanent damage.

What happens if a heart attack is not treated immediately?

Without urgent treatment, the heart can stop pumping blood entirely leading to death. Permanent heart damage or heart failure are also risks if treatment is delayed.

😦 What causes a heart attack

This paragraph explains what causes a heart attack. It states that fatty deposits can build up and block the coronary arteries, which supply oxygenated blood to the heart. If an artery gets blocked, it can lead to a heart attack. It describes the signs of a heart attack like chest pain, shortness of breath, nausea etc. It also lists risk factors like smoking, diabetes, high cholesterol etc. And it emphasizes the importance of a healthy lifestyle and managing stress to keep the heart healthy.

Keywords

💡heart attack

A heart attack, also called a myocardial infarction, occurs when blood flow to part of the heart muscle is blocked, causing damage to the heart muscle. This is a key idea in the video which explains what causes a heart attack at the cellular level when fatty plaque builds up and blocks the coronary arteries.

💡coronary arteries

The coronary arteries are the blood vessels that supply oxygen and nutrients to the heart muscle. The build up of fatty deposits called plaque in the coronary arteries is what leads to blocked blood flow and oxygen supply, resulting in a heart attack.

💡blood clots

When a blocked coronary artery ruptures, the body responds by forming blood clots around the rupture. This blood clot leads to complete blockage of the artery, cutting off blood supply to the heart muscle and causing a heart attack.

💡plaque

Plaque refers to fatty and hardened deposits that build up on the inner walls of the coronary arteries. This plaque narrows the arteries, restricts blood flow to the heart, and can rupture, leading to blood clot formation and heart attacks.

💡angioplasty

Angioplasty is a procedure used to treat blocked coronary arteries. It involves inserting a thin tube with a balloon to open up blocked arteries and restore blood flow to the heart muscle.

💡bypass surgery

Bypass surgery is a more invasive treatment option for blocked coronary arteries. It involves taking a blood vessel from another part of the body to redirect blood flow around the blocked part of the coronary artery.

💡stress

Stress makes a heart attack more likely by elevating blood pressure and heart rate. The video recommends stress management through relaxing activities to prevent heart problems.

💡diabetes

Diabetes is a risk factor for heart disease that can lead to plaque buildup in the arteries. Keeping diabetes under control can help prevent heart attacks.

💡symptoms

Recognizing the symptoms of a heart attack quickly is vital. Main symptoms include chest pain, shortness of breath, nausea, lightheadedness. Getting prompt treatment can save lives.

💡prevention

Lifestyle changes like healthy diet, exercise, avoiding smoking can significantly lower the risk of a heart attack by preventing plaque buildup and keeping the heart strong.

Highlights

Fatty deposits or plaque start developing on the walls of the coronary arteries

If this plaque ruptures, the body forms blood clots leading to complete blockage of the artery

Blocked arteries cut off oxygen to the heart muscles, cells begin to die within minutes

This leads to a heart attack, medically called myocardial infarction

If help doesn't come immediately, the heart may stop pumping blood

Chest pain, discomfort in the arm, neck, jaw or back are common signs of a heart attack

Shortness of breath, cold sweats, nausea also indicate an impending heart attack

Fatigue and weakness can be a major sign for women and elderly people

High blood pressure, cholesterol, smoking raise heart attack risk

Doctors may do an ECG to check the heart and blood tests for muscle damage

Angioplasty opens blocked arteries; bypass surgery reroutes blood flow

Prevention includes healthy diet, exercise, no smoking

Relaxation and stress management also critical

Small daily steps keep the heart healthy and strong

Silent heart attacks account for 1 in 5 and have no symptoms

oh little kitty you seem to be eating

junk and lacing around too much these

days please get active to help your

heart otherwise such a lifestyle is

known for causing a heart attack really

how well let us explore that by

answering a heartbreaking question what

causes a heart attack zoom

in the human heart a Marvel of

biological engineering is responsible

for pumping life sustaining blood

throughout the body however this vital

organ is not Unstoppable and one of the

most feared cardiovascular events is a

heart attack claiming around 7 million

lives worldwide every year

but what causes it in the first place

you see like all muscles our heart needs

oxygen to function properly it gets the

supply of oxygenated blood from vessels

called coronary

arteries however due to various reasons

fatty deposits or plaque start

developing on the walls of these

arteries at times these fatty pla

can get hardened lumpy or

inflamed causing a partial blockage that

reduces the flow of oxygenated blood if

this block ruptures your body perceives

it as any other injury and within

minutes starts to form blood clots

around it leading to the complete

blockage of the artery as a result blood

flow is cut off to the heart muscles

and oxygen sted cells begin to die

within a few minutes leading to a heart

attack medically known as myocardial

infection if help is not received

immediately things may go downhill as

the heart will stop pumping

blood and in worst case scenario the

person may pass away so it's vital to

understand the war in signs to identify

the lurking threat of a heart attack and

what are

they the most common signs include

crushing chest pain or discomfort that

may spread to the left arm neck jaw or

back at times there are other subtle

signs such as shortness of breath cold

sweats nausea and Li headedness for

women and older people constant

tiredness and weakness can be a major

sign of a weak heart not only that but

certain things make a heart attack more

likely like high blood pressure high

cholesterol smoking diabetes being

overweight and not being active so if

you notice people showing any of the

said symptoms with no sign of

improvement then it's better to

immediately take them to the nearest

hospital the doctor might do a test

called an

electrocardiogram or ECG to check the

heart's electricity and a blood test for

muscle damage if they find a problem the

cardiologist can do an

angioplasty using a thin tube with a

balloon to clear blockages is in the

artery in serious situations doctors

might do bypass surgery they take a

piece of vein from another part of the

body and redirect the blood flow around

the blockage to fix the heart but

remember it's better to prevent Problems

by making Lifestyle Changes which can

significantly lower the risk of a heart

attack yes to keep your heart strong eat

healthy foods like fruits and veggies

play and move around for regular

exercise and stay away from smoking

listen to your body get enough sleep and

manage stress with relaxing activities

like drawing or playing remember small

steps every day can make a big

difference in keeping your heart healthy

and and strong to know more check our

video how your heart

Works trivia time did you know a heart

attack can happen suddenly without a

person knowing it yes this is referred

to as a silent heart attack and these

account for one in five heart

attacks it's sketching time today's
