HEART FAILURE
ANGINA

HIGH BLOOD PRESSURE
DISTURBED HEART RHYTHM

Thickening and atheroma may cause constriction of the coronary arteries causing coronary artery disease. CAD is No.1 cause of heart attack.

Plaque is the build up from high cholesterol, eating to much fried and fatty food, with hereditary factors that cause heart disease. The plaque is like a clog that can decrease the blood supply, hence why there is cholesterol medicine, and a food regimen when you are diagonsised with heart disease or high cholesterol. If a organ is starved of oxygen is will die, for example plaque in a main artery, can clog, causing a lack of blood/oxygen to the heart, causing a heart attack. hope this helped
