What Causes A Heart Attack?

What Causes A Heart Attack?


For quite sometime I’ve been wondering what causes a heart attack and why is it even called a heart attack. So in this video I’m gonna be explaining those things. Coming, right up. Hey guys and gals, Aman here and you’re watching Heart Limits. So let’s start off by the concept of heart attacks. Well while I was growing up my family has quite the history with heart attacks and I always thought that when you say “heart attack” it is the literal attack, like the heart is attacking a person or the heart is rather being attacked in some way. But my oh my was I wrong. Well, a heart attack is actually something that happens when the heart doesn’t receive enough oxygen, so in some way the heart is suffocating. So why didn’t they just call it heart suffocation or heart missing oxygen or something? Its, I don’t know… Anyway that’s how they call it. So the heart is actually (one of… no the heart is) the hardest working muscle in the body. And the problem is whenever a muscle doesn’t receive oxygen, or rather oxygenated blood to be more specific, the cells in those muscles die. So the question is, how does this actually occur? Well, let me explain. The heart has coronary arteries and that’s basically where the oxygenated blood passes through, but the problem is a person receives a heart attack whenever there is some type of blockage that’s in the way. So, how would you call these types of blockage? Well, you would call it as plaques. Well normally when you hear the word plaque, for some reason people usually think of the plaque that’s found in the teeth but actually there’s three types of plaque. You have plaque in the teeth, plaque in the eyes and even plaque in the heart. So for this topic we’re going to talk about the plaque that builds up in the coronary arteries of the heart. So this plaque is actually quite interesting in some way. Well I wouldn’t really call it interesting since it can actually kill you. The plaque is made out of a couple of components and some of which are I believe you are familiar with. It’s built up with some calcium, it’s built up with some fat and it’s built up with some cholesterol. And the problem is as these certain ingredients or certain materials or certain particles start to build up in your coronary arteries, what happens is it can end up in a couple of states. The plaque can either become soft, the plaque… Oh I guess that was a big fish. The plaque can be quite soft. The plaque can also be hardened, in some way calcified. The plaque can also be chunky and sometimes the plaque can also be inflamed. So whenever there is plaque, there is a blockage that happens and it’s quite hard to imagine a plaque actually so I guess to simplify, it’s like peanut butter inside your arteries. So imagine a tube where there is some peanut butter in the way and the blood; oxygenated blood, cannot pass through because there is that freaking peanut butter that’s making that blockage. Okay? And the creepy thing, creepy? Yeah I guess you would call it creepy. And the creepy thing with this plaque is that there are times where it can have some types of cracks, and not only cracks it can also have these types of mini chunks that just break off. When that happens, whenever blood passes through, they would actually slowly nudge in those little cracks; those little chunks where something broke off from, and it would create a blood clot. And the problem with a blood clot is that it happens pretty fast, so within a few minutes a partial blockage would then become completely blocked and whenever there is a blockage, the area which is not receiving the oxygenated blood, it’s cells will just slowly die. So that’s pretty pretty severe if you could say. So now you know. Keep in mind that a heart attack is not literally the heart attacking you and it’s not literally the heart being attacked but it is the heart not receiving the right amount of oxygenated blood to keep it operating or rather to keep it in some way alive. So once again, Aman here and you’re watching Heart Limits. I hope you like this video. I tried my best to keep it as simple as I can and please don’t forget to subscribe and hit that like button.
