7 SINTOMAS QUE SEU CORPO DÁ ANTES DE UM INFARTO DO CORAÇÃO

Hi! In this video you will be able to recognize the first signs and symptoms of a heart attack. Heart attack is the biggest cause of death in Brazil and in the world and we know that cardiovascular diseases kill about 400 thousand Brazilians a year, according to the Brazilian Society of Cardiology.

And the sooner you think about a heart attack, the faster you get to the hospital, the better the treatment and the lesser the consequences for your heart and the better chance you have of surviving it. So pay attention! In addition to the initial symptoms of a heart attack, I'm going to talk about the types of heart attacks, the causes of a heart attack and why there has been a worrying increase in the number of cases of heart attacks in young people under 40 years old recently.

So stay tuned! But first, enjoy the video — let's make this video the channel's record holder… Can we get past 300,000 likes? Help there!

Data from SBC show that less than 5% of the Brazilian population knows how to recognize the initial symptoms of a heart attack!

And many lives are lost because of it! So share there. And tell me: have you ever had a heart attack?

Know someone who has? What part of Brazil are you from? Write down there.

What is a heart attack or an acute myocardial infarction, AMI? A heart attack is a frightening experience. If you've had a heart attack, or have been close to someone who has, you should know this well.

As I said, a heart attack is the main cause of death in Brazil, and it is a medical emergency. The heart is a muscle that pumps oxygen- and nutrient-rich blood to the rest of the body through the aorta. Above the heart are several small arteries known as coronary arteries and they supply the heart muscle with oxygen and nutrients.

In infarction, or acute coronary syndrome, there is a blockage of blood flow in one of the coronary arteries. Atherosclerosis is the main cause of infarction and results in the continuous deposition of cholesterol in these vessels over the years. Because of stress, a scare, vigorous exercise, or lack of sleep—in the United States, where it is well documented, that in the change from daylight saving time, where 1 hour of sleep is lost, there is a 24% spike in heart attacks, year after year, and when it goes back to normal, there's a 21% drop in heart attacks—the fatty plaque that breaks down.

When the fatty plaque breaks down, the platelets will notice and try to stop it, resulting in the formation of a blood clot, which then causes a partial or complete blockage of the involved coronary artery. Other, less common causes are vasospasm—which is triggered by drugs such as cocaine, smoking, stress or cold and results in a sudden spasm of the coronary artery and the other cause is coronary artery dissection in which the inner wall of the coronary artery ruptures, resulting in a blockage of blood flow. Blockage of any one of the coronary arteries causes muscle ischemia— a lack of oxygen and nutrients in the part of the heart muscle supplied by that artery, which will cause the heart muscle to die, the acute myocardial infarction.

So, during a heart attack, the heart muscle tissue is dying because there is no blood flow to that artery in the heart. That's why we say that time is muscle! The faster you get to the ER and get treated, the less damage your heart will do.

And vice versa too, the longer you take to seek help, trying to wait for the symptoms to pass, the greater the damage to your heart muscle. And what are the symptoms of a heart attack? People often don't realize they are having a heart attack, either because they don't recognize the early signs or because they don't consider them serious enough to call.

That's why it's important to pay attention to your body! Some heart attacks are sudden and intense. But most start out slowly, with mild pain or discomfort.

So 1st symptom- Discomfort in the chest. Most heart attacks involve a pain or discomfort in the center of the chest that lasts for more than a few minutes (usually 5 minutes or more) they are not stinging or stinging that last a few seconds, it is a longer pain that may go away and then go away. return.

It can feel like uncomfortable pressure, a heaviness, a tightness, fullness, or even burning in the chest. 2nd symptom- Discomfort in other areas of the upper body, such as pain or discomfort in one or both arms, numbness in the hands, pain in the back, neck, jaw or stomach. 3rd symptom- Shortness of breath.

And this shortness of breath can occur with or without chest discomfort. Because if your heart can't pump blood well (as is the case with a heart attack), you may experience shortness of breath or difficulty breathing . It's cold, slimy and usually the person is pale.

Then you suddenly start sweating, and your skin is cold and clammy. 5th symptom - nausea and vomiting - you may feel nauseous or have a stomach upset, this is due to vagus nerve reaction. 6th symptom- dizziness.

Dizziness can occur with a heart attack and are usually symptoms that women describe. Some women report feeling like they might pass out if they try to get up or try a little harder. 7th symptom- Anxiety.

You may feel a sense of doom or feel like you are having a panic attack for no apparent reason. If you have any of these symptoms, don't expect to go away. Call Samu, call a family member or friend, call the taxi, order an Uber and go to an emergency room.

In cardiology there is the concept of the golden hour, where a person's survival will depend on the action they and the doctor take during the first hour of the event, because most deaths from cardiac arrest happen during this period. Is there a difference in symptoms between men and women? Chest pain (angina) is the main symptom of a heart attack in both women and men.

But women describe the pain as more like tightness, or tightness, in the chest, while men tend to describe it as a "heaviness. " In addition, women are slightly more likely than men to experience shortness of breath, nausea and vomiting, and back or jaw pain. And one of the common symptoms in women is fatigue—so much so that some women may even think their heart attack symptoms are flu or covid symptoms.

It's important Not all people who have heart attacks have the same symptoms. Some people have mild pain; others have more intense pain. And in other cases, like diabetics, they may not have chest pain.

And we also have the cases where the first sign of a heart attack can be a cardiac arrest. But the more signs and symptoms you have, the greater the chance you are having a heart attack. Some heart attacks occur suddenly, but many people experience warning signs and symptoms hours, days, or weeks before the event.

The first warning may be recurrent chest pain or pressure (angina) that is triggered by exertion and relieved when a person is at rest. If you can notice these symptoms and appreciate them before you have a heart attack, even better. What are the types of heart attacks?

We have 2 types of infarction An ST-segment infarction, where the clot is totally blocking the blood flow to that artery, so the doctor can see through the ECG that you are infarction, and because it is a more serious infarction, he will have to act quickly. Or, in the second case, A heart attack without supra, where there is a partial blockage of the artery and, to the bad luck of the doctor, it shows in the electro, but the muscle is suffering, and the cardiac enzymes will rise as troponin, in the blood test. What are the risk factors for heart attack?

As I said, the main cause of a heart attack is atherosclerosis, so what causes atherosclerosis increases your risk of a heart attack. Heart attack risk factors include: Age. Men over 45 and women over 55 are more likely to have a heart attack.

Women have problems later on because estrogen protects them. Cigarette- This includes both smoking and secondhand smoke. High pressure.

Over time, high blood pressure damages the arteries leading to your heart, developing atherosclerosis. High LDL (which is bad) cholesterol, low HDL (which is good) cholesterol, high triglycerides , high lipoprotein A all increase your risk of atherosclerosis Obesity. Obesity is linked to high blood cholesterol levels, high triglyceride levels, high blood pressure and diabetes.

In addition, visceral fat inflames the body, increasing C-reactive protein, which is a marker of cardiovascular risk. Diabetes. Over time, high blood sugar can damage blood vessels and nerves in the heart.

Family history- this is extremely important. If your siblings, parents, or grandparents had early heart attacks (at age 55 for men and age 65 for women), you may be at increased risk. It increases your chances of having significant atherosclerosis by 4.

5 times as well. Sedentary lifestyle- Being inactive contributes to hypertension, obesity, diabetes and high blood cholesterol levels. People who exercise regularly have better heart health.

Stress. Stress inflames, increases blood pressure, increases blood sugar, makes you sleep poorly and, yes, increases the risk of a heart attack. Drgs- such as cocaine or even amphetamines, can trigger a spasm in the coronary arteries that can cause a heart attack.

And in the long run they cause atherosclerosis. Why did heart attacks increase in young people? According to the Ministry of Health between 2010 and 2019 (before covid) there was a 59% increase in hospitalizations for heart attacks of people up to 39 years old and almost 10% in deaths.

This is because risk factors—hypertension, diabetes, high cholesterol, obesity, stress, smoking, and physical inactivity—are increasingly common in young people. So it is the fault of the dangerous lifestyle adopted by them. And there is a problem, too, because in this population the symptoms of angina, that pain in the chest when walking, may not precede the heart attack.

What are the treatments for a heart attack? Treatment of a myocardial infarction usually involves oxygen therapy to increase the amount of oxygen reaching the heart muscle, aspirin or other antiplatelet therapy, nitroglycerin and morphine to relax the coronary arteries and relieve pain, beta blockers to reduce the heart rate and reduce oxygen consumption in the heart. And the doctor can opt for: thrombolytic therapy that serves to dissolve existing blood clots or, better yet, if he is in a hospital prepared, coronary angioplasty.

For angioplasty, a thin and long tube (the catheter) will be introduced through an artery and will reach that coronary artery that is clogged. The catheter has a small balloon at its tip. As soon as the catheter arrives in the right place, the doctor will inflate the balloon, squeezing that fatty plaque against the sides of the artery, opening more space for the blood flow that will return to irrigate that area.

The stents are like a little piece of metal that will expand and cover that plate. It 's like a tunnel that won't let that fatty plaque narrow or close that artery again. How can you lower your risk of having a heart attack?

You should reduce risk factors: Half of heart attacks can be prevented just by changing a few habits. For example, quitting smoking reduces the risk of a heart attack by 30%. Keep your blood pressure under control— 120x80 If you have diabetes it is important that your blood sugar is well controlled to avoid all the harmful consequences of diabetes Eat right A healthy diet, low in sugar, soft drinks and salt, lots of fruits and vegetables, little meat red meat and fried foods, reduces your cardiovascular risk.

Lower cholesterol and triglycerides. Get some exercise- get out of your chair and get moving! Try to lose weight if you are overweight or obese.

Get good sleep- 7 to 9 hours a night AND make friends— we know that loneliness and social isolation increases your risk of a heart attack by almost 30%. And get a cardiological checkup. Those whose parents manifested early heart disease should start earlier than others, around age 20.

And cardiological exams are increasingly reliable. Before, we only had non-invasive tests that made us deduce that the patient had no obstruction - for example, an exercise stress test. Sometimes the person did an exercise test, ran a lot on the treadmill, did not change electrocardiograms, had no chest pain, the cardiologist congratulated him and a few days later he had a heart attack.

Today we have more complete exams, such as coronary angiotomography - which shows how the arteries are inside, if there is any plaque? Without needing a cardiac catheterization, which is a very good exam, but invasive. Of course, CT angiography is not for everyone .

It's an exam that has radiation, you have to use contrast (which can give a reaction, kidney problem), it's a relatively expensive exam. But it is important to know that we have these cards up our sleeves, and from time to time we need to use them. And lastly, I want to give a warning to those who are at risk of having a heart attack or have had a heart attack Have an emergency plan of action in case you or someone in your family is at high risk of having a heart attack.

Write down the list of medications you are taking, and which medication are you allergic to? Who is your doctor? How is your basal electrocardiogram (take a picture and save it on your phone).

Which hospital is closest to your home? Do you have a cardiologist? Do you have emergency hemodynamics?

All of this can help you to get the best and fastest medical care possible. Did you like the video? And what's the next video you're going to watch ?
