Adding on to dxszzcylm's answer....it also depends on where the thrombus occurs. It is also possible to choke off the blood flow to the heart, losing back pressure so that the heart cannot operate. Sudden death is much more likely, though, if it reaches the brain, because a lack of blood flow to the brain means a lack of oxygen, and death comes very quickly after that.
A thrombus is a blood clot. The coronary arteries are the blood vessels that supply the heart muscle itself with blood. A clot in the arteries will decrease blood flow to that muscle.
This is also called a heart attack. The degree of blockage in the heart and amount of time to re-perfusion treatment will dictate how much of the heart muscle dies. If a large enough portion of the heart dies, the heart will be unable to supply the body with an adequate amount of blood and the patient will die.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
