Many people are full of plaque and never have a problem. Others have little, but one rupture can cause a big problem. It is like a land mine. We know the classic risk factors that put the plaque there. But what triggers it in some people and not others is still being researched. Stress is one risk factor. AKA type "A" personalities.
