    The buildup of atheroma or fatty plaque in the wall of the coronary artery narrows the lumen of the artery resulting in ischemia or inadequate blood flow to the heart. The atheroma may ulcerate releasing materials that cause blood to clot on the surface of the plaque. As the clot enlarges it totally obstructs the artery causing a myocardial infarction or death of cardiac tissue downstream to the obstruction.

    Hi Robotnic,

    Ischaemia is the term used to describe an area in the body where there is a lack of blood supply and therefore a lack of oxygen supply.

    Thrombosis is a clot of blood which has formed in a blood sometimes but not necessarily a result of long term ischaemia. If a clot has formed and a piece of the clot breaks off and travels to another part of the circulation, that is called an embolus or embolism.

    Atheroma is a build up or swelling in an artery usually of fatty lipids, the atheroma can cause ischaemia, and go on to form a clot (thrombosis) This can happen in any part of the body. However if it happens in blood vessels supplying oxygen to the hears it will cause that part of the tissue of the heart to cease functioning since all organs are reliant on oxygen in order to carry out their function.

    This will in turn cause a heart attack MI or myocardial infarction)

    Hope this helps.

    Love Mel.
