The coronary arteries are the blood vessels that supply blood to the heart.
Blood then flows slowly or is blocked from flowing through the artery.
Blocked arteries can cause heart attacks, strokes, or death. Coronary artery disease is a slow process that occurs over time. Some risk factors that speed up the disease are increasing age, family history of heart disease, high fat diet, elevated cholesterol, smoking, lack of exercise, high stress, obesity, diabetes, and high blood pressure. The symptoms of angina may vary from person to person. The symptoms may even vary with each episode.
