Heart disease and heart attacks | Miscellaneous | Health & Medicine

 I think most of us know what the heart does to our bodies. It pumps blood and most importantly, it absorbs blood from the rest of the body. That's blue here in this painting because that blood didn't carry oxygen and pumps that blood into the lungs where the blood gets oxygen and then comes back out of the lungs, expressed like red blood, now that it has oxygen in it. And then that oxygenated blood is put into the whole body And I think again, most of us have a common perception that when people talk about heart disease or heart disease, what we are learning, they are two different things, related but different, that is related to vascular blockage. so when I was young and I started to feel vascular blockage and I knew enough that the heart is about pumping blood in the body. I think artery people were talking about these big arteries that came from far away from the heart all over the body that somehow these things got blocked. so let me draw that, a different color that you can see that this was mine 



this is what I thought people were talking about when they said blockage and maybe when they were closed enough, suspended blood flows to another part of the body in some way and that would really kill a person. I want to make it clear right now. Those are not the arteries that people talk about in obstruction when people talk about heart disease or heart disease. The arteries they are talking about are arteries that bring blood to the heart Remember the heart itself is a tissue. It also needs oxygen. So you've got these veins right here, red tubes. Those are the muscles. and blue to the veins. 

(causes of heart attack)

They remove weakened blood from the body's tissues. And these are called blood vessels. This one is at least from my point of view or looks like it is on the right, or at a person's heart, it is on the left. This one is called the coronary artery or LCA. And this red side is called the right heart artery. with blocked or obstructed arteries, they talk about blood vessels. They talk about things that bring blood to the heart. So let's bring one of them .... Maybe we can bring it right here, that part of the vein. That's the tube .... it's clear where I draw it. Bring me closer here. So over time, I don't go into details about how this happened. It's the title of another video. You can build these plates around the artery wall.

 So over time if a person doesn't have the right diet, or maybe has a tendency to it, you may find that these so-called plates build walls of the arteries. We call this the plaque. With the formation of these veins that block the blood vessel itself, that disrupts the arteries. This is kind of a tube over here. Let me draw bloodSo the formation of these inscriptions we call atherosclerosis. So you would think that if you have these substances, it reduces the actual blood supply at the bottom of the river to that distraction. , which is ischemia that occurs. Ischemia is therefore a reduction in blood flow and oxygen downstream from the right side of the river. This is what we call cardiovascular disease or heart disease. This, therefore, causes cardiovascular disease, sometimes called heart disease. A painful heart attack will no longer work because the coronary is already referring to the heart. And so you may think that the lower extremities do not get all the oxygen they need, especially when this person, or anyone whose heart, when they are working hard, needs extra oxygen. The heart needs to pump a little harder.(myocardial infarction)

 If the cells below don't get all the oxygen they need, you might think that the heart may not be able to provide all the functions or any heart of this, that they had to do. And when that happens the so-called heart failure. Heart disease is therefore one of the causes of heart failure. Now I want to be clear, heart failure does not mean the heart stops. The fact that the heart is suspended and the person is dead, literally means that the heart is failing to do what it should be doing. Failed to provide for that person's needs, so it is not enough or sufficient to provide enough for that person. Another sign that a person may have a heart attack, a disorder or ischemia, or oxygen deprivation, is that they may experience this type of pain. strangled asthma called angina pectoris or sometimes angina. 

Very few people claim to be part of the pectoris. Sometimes you hear people say oh I'm not. Angina pectoris, which is really painful in the chest, angina actually comes from describing this type of feeling of snoring, and pectoris is in the chest. This is a choking sensation in the chest. This is a sign of heart disease. Now, this is by no means the situation you want to get rid of because your body can no longer function as well as it could, as it could. Sometimes as I might explain here there is a poster. Some plaques are actually unstable. These plates just grow and grow and grow. It probably makes heart disease worse, heart failure worse, and angina pectoris worse. You can imagine that all of this blood flow, as the plaque grows, the blood flow becomes turbulent around these plates. It has to move very fast in this small section. It comes out of chaos inside and creates this conflict with everything else.(major heart attack)

 At times, you may think that the plaque is unstable and, in fact, cracked. Let me draw a cracked crust over here .... let me draw the same .... I will draw a crash. Now the crust is torn. It was too big. Perhaps the disturbed blood flow helped to reactivate this and anything else. For whatever reason, it cracks. When it explodes, I now suddenly make the process easier here. Now the contents of this plaque: lipid, cholesterol, fats, dead white blood cell. Now it is suddenly exposed to blood flow. especially the clotting factor in the blood. This is a very thrombogenic activity. Thrombogenic, a very good name. That is to say, which often causes blood clots. What happens is that, as soon as this type of thing happens, it can actually happen in seconds or minutes. Suddenly you can have these thickened things that form a cluster right here in the plaque itself. (oxygen level during  heart attack)

As this happens, it begins to actually block the blood vessel, sometimes it can completely block the blood vessel, and when that happens, it severely restricts the flow of blood downstream from there, and it may close. If you do, the cells at the bottom of the river will lose their oxygen and die. This right here is called an infarction. An infarct is actually a dead heart muscle You would think that when the heart tissue starts to die, this is worse than what we described with heart disease. It is not the only heart disease that does not get enough oxygen, it is now dead. It turns into dead tissue. This process of completely or almost completely depleting oxygen cells to death is heart disease.

 Let me completely block this artery to make the point clear. This is a major cause of heart disease. This is less likely to occur but sometimes the plaque can go down to the bottom of the river, a form of thromboembolism. It could be these critical, clusters around it. actually, go and block the artery down the river and become embolism. That can also block the artery and cause the tissue to die. But the main cause of this is a large blockage that can occur very quickly and completely block the artery. There is one last word I want to touch sometimes combined with all the other words, which is the binding of the heart. That is because sometimes we use them in the same context one thing can lead to another. A heart attack is not a heart attack. A heart attack is a real heart attack.(heart attack symptoms)

 What I just described in a heart attack, people can get a heart attack. They will have part of their muscle tissue inherited. Part of it does not, it is what they call myocardial infarction. Myocardial infarction refers to heart tissue or dead heart muscle, sometimes called myocardial infarction. That is not a physical binding because you can get some of your heart tissue dead and you can live. Your heart would be paralyzed but you will continue to live. A heart attack is actually a condition of your heart. This can obviously lead to death. If you have a severe heart attack, if you have enough muscle and you starve to death, a rash occurs. This can lead to heart failure. Of course, a heart attack is not the only thing that can cause a heart attack. I want to again distinguish between heart attack and heart failure, because it sounds the same way, it sounds like the heart is failing. A cardiac arrest stops the heart. Heart failure actually simply means that the heart cannot supply all the body's needs
