Does High Blood Pressure Make the Heart Thicker?

Read Transcript

Now this is a normal human heart. it's about size of fist, it's supposed to look like. Notice the thickness of the wall, it's not too bad, it's very thin. When a heart has been subjected to high blood pressure, these walls would get a lot thicker and at first it begin to look like this.

Let me just put this together so that you can compare those two. Notice the thickness difference between these. Can you all see that? See how one is a lot thicker than the other? See this is sort of thin over here. It looks like a chicken gizzard. Chicken gizzard Yea, I guess I could see that.

Yes, now do me a favor. Pinch that, pinch that. Compare that thickness to this. It's hard. It's a lot thicker, isn't it? Yea. Is that pretty clear? Now, here's the deal, from this point to this point, that thickening in the muscle is sort of like a muscle bar weight lifter. Lifting the weights over, eventually it gets so rigid, it can't move around, that's what happening with this heart.

Eventually, take this off, this is what happens. Now, we're talking about a change that's no longer reverse able. There's an animation that shows the 2 big muscle chambers of the heart. The 2 muscle chambers are squeezing together. One of them, the purplish one squeezes to the lungs.

They'll be here. This chamber pushes the blood up to the body and gets thicker and fixes the muscle getting thicker and thicker and obliterates the space there's no space for blood to go anymore, and eventually the heart is so stiff. It can't let the blood come in anymore. That's called the Hypertrophied heart, a thickened heart.

Your doctor is going to tell you that your heart got thick. That's what I want you to see when you hear that from now on. When a heart is that thick, unfortunately, when the blood can't come in, it backs up into the lungs. So you get shortness of breath.
