[yamenhawit]

so what exactly is "heart disease"? is it synonymous to "heart failure"?

[khanacademy]

@yamenhawit Heart Disease, Coronary Artery Disease and Coronary Heart Disease are all the same thing. Heart failure may occur because of heart disease.

Is it legal to use these images in this video? I know there are free/cc anatomical illustrations, but they would have to be attributed... Not wanting to accuse anyone, just raising awareness of a potential problem.

@SalsaTiger83 The right two images are in the public domain and I attribute the left-most one in the description

Sometimes when i'm asleep I wake up from a shiver or a vibration that comes suddenly and lasts for 2-3 seconds, and they stop once I'm awake. some people told me it's related to a heart disease. Is it true? Can anyone explain to me why I get these vibrations

i agree until you you started talking about how the blood clots it doesnt actually clot around the plague that breaks loses it clots around the membrane that broke were the plague was builiding up until no blood gets to the muscles of the heart and then you have a heart attack.

@ro33han I wouldn't, his videos are generally good but the medicine videos are extremely basic and do not offer much practical application. I'm not surprised. He's clearly very intelligent but we can't expect him to know everything. He missed out the point that LDL has to be oxidised into a non-polarised molecule before it can come harmful.

What is the difference between this video and your other regarding Heart Disease and heart attacks?
