And for a variety of reasons, Dr. Ridker decided that it had to be a process called inflammation, and what his basic research showed that the inflammation of the arteriole wall led to these clogs in these arteries becoming unstable, and they would burst, and that would cause a clot, and that would lead to a heart attack.
