The right coronary artery circles the right side and goes to the back of the heart. The left coronary artery further divides into the left circumflex and the left anterior descending artery. These two left arteries feed the front and the left side of the heart. The division of the left coronary artery is the reason why doctors usually refer to three main coronary arteries. (Fig. 2 - Coronary Arteries)SYMPTOMS OF CORONARY HEART DISEASE There are three main symptoms of coronary heart disease: Heart Attack, Sudden Death, and Angina.

Coronary and Coronary Thrombosis2 are terms that can refer to a heart attack. Another term, Acute myocardial infarction2, means death of heart muscle due to an inadequate blood supply.
