As i understand it, and im not suggesting my understanding is in any way adequate ;p , heart attacks and strokes are mainly caused by arterial blockages that prevent blood from reaching the heart muscle or areas of the brain. This is usually caused by buildup if plaque in the arterial walls due to high cholesterol, or due to bloodclots, for example, after traumatic injury.
Im not sure about bloodclots, but in terms if clogged arteries, is there no way we can screen for them? It seems we just sit and wait for a heart attack before doctors start looking for clogged arteries to clear them out. And i dont think most people survive their first hesrt attack.
Im picturing something like a dye thats goes in your blood and is monitored by a machine that can use it to detect arteries that are clogged up or wherever blood flow is impeded. I think ive read about radioactive dyes, chemucaks that can do this?
Does anything like that exist? Are there techniques for screening to catch clogged arteries before a heart attack on the horizon? Do they already exist and i just dont know about them?
