This is usually caused by arteriosclerosis with narrowing of the coronary arteries, the culminating event being a thrombosis (clot).</P> Aside from designating the process of forming the infarct, infarction is synonymous with the infarct itself.</P> The word 'infarction' comes from the Latin 'infarcire' meaning 'to plug up or cram.' It refers to the clogging of the artery.
