One thing I cant figure is why I got that blood clot in my right coronary artery. When they did the angiogram they found that my arteries were wide open, no narrowing with plaque etc. In fact, once they had sucked that clot out of my artery he wanted to put a stent in but they didnt have one big enough to fit! He said my arteries were huge and they did not have a stent that big. So it doesnt sound like i had a plaque that ruptered. Most of the cardiologists I saw told me thats what happened. WOUldnt the artery be narrowed down?
The answer is no, most heart attacks occur from a plaque that is less than 50% in size. Meaning, you can pass a stress test with ease and still go out and have a heart attack.
A plaque of just 5 or 10%, virtually no narrowing can still rupture and cause a heart attack. The plaque can become unstable and it is a very dynamic process, it happens all the time, in fact, Swatdoc is probably rupturing one right now.
The unfortunate fact is that yours led to a heart attack but it does happen on a not too frequent basis.
The plaque isnt the hardiest of entities. It has the consistency of toothpaste with a friable cap over the top. The theory being that blood pressure surges can rip open or rip the skin on that toothpaste blister in your artery, in laymen's terms. That is probably done by the sheer force of blood pressure during the squats you did.
That little teeny plaque you had, then spilled its chemical messengers into the bloodstream and the body reacted thinking you had a cut on your finger and sent clotting factors and such. It formed a clot in the RCA.
Since plaque rupture is dynamic, that it is why it is suggested that people take a baby aspirin to make blood cells "slippery" when this happening to lessen or prevent a major myocardial infarction.
Your query does make sense as to "if they arent narrowed, why did this happen", the answer is that, most heart attacks occur with small blockages, not large b/c of plaque rupture.
When arteries are mostly narrowed they produce symptoms. Symptoms are then relieved by stents or bypass. Stents on an elective basis do not prolong life, they relieve symptoms unless done so to have other surgeries where cardiac function has to have a reserve.
Bypass does prolong life according to studies, but stents do not. But this is a whole 'nother discussion.
The fact that you had large arteries and still had a plaque rupture, and after heavy exertion, makes you more of a textbook plaque rupture than anything.
The plaque rupture, body thought you cut your finger, doesnt know the difference and clotted it off. Unfortunately it clotted off the whole artery like a traffic jam. The muscle down stream got starved for oxygen. Since all the nerves in the thoracic cavity are jumbled. You felt referred pain and everyone feels it different depending on their anatomy.
Hope that helps answer your question
