Coronary artery disease is a dangerous blockage of the coronary arteries. This disease is typically caused by a long-term buildup of fatty substances or plaque. Answer and Explanation: Become a Study.com member to unlock this answer!Create your account ...
Atherosclerotic coronary artery disease:Over time, a sticky, fatty substance called plaque can build up in your arteries. That makes it harder for blood to get through and raises your risk for a heart attack or stroke. Atherosclerotic coronary artery disease is when plaque builds up along the w...

calledplaquebuilds up in the walls of your arteries. Plaque contains fat, cholesterol, calcium, and white blood cells. It can lead to a heart attack or stroke if the plaque ruptures and forms a clot that cuts off the blood supply to the heart (in a heart attack) or the brain (in a...
The condition, also known as hereditary hemorrhagictelangiectasia, occurs when capillaries fail to develop normally. As a result, the veins and arteries directly connect in certain areas of the body. The veins and arteries have different pressure levels, so ruptures tend to occur at the spots whe...

Stress tests can detect when arteries have 70% or more blockage. This severe narrowing is what causes the severe chest pain called angina. But normal results from a stress test do not rule out the possibility of a future heart attack. This is because a plaque can still rupture, form clots...
Additionally, there is growing evidence that inflammation in the arteries can cause plaque to rupture, triggering the formation of clots. It is a clot that may eventually plug an artery that has been narrowed by fatty plaques, thereby cutting off the supply of oxygen to a portion of the heart...
If the heart is asked to do more work and pump harder and faster, enough oxygen may not be able to be delivered beyond the blockage to meet the energy demand of the myocardium and this can cause the symptoms of angina to occur. If a plaque ruptures, a blood clot may form that ...
In some cases, plaque can break or rupture. As a result, blood cells called platelets will try to repair the artery, forming a blood clot. Like gunk in a clogged drainpipe, this buildup prevents a free flow of blood through the arteries. Blood carries oxygen and nutrients to the heart....
