Stable angina

Angina - stable; Angina - chronic; Angina pectoris; Chest pain - angina; CAD - angina; Coronary artery disease - angina; Heart disease - angina

Stable angina is chest pain or discomfort that most often occurs with activity or emotional stress. Angina is due to poor blood flow through the blood vessels in the heart called the coronary arteries.

Heart - front view

The external structures of the heart include the ventricles, atria, arteries and veins. Arteries carry blood away from the heart while veins carry blood into the heart. The vessels colored blue indicate the transport of blood with relatively low content of oxygen and high content of carbon dioxide. The vessels colored red indicate the transport of blood with relatively high content of oxygen and low content of carbon dioxide.

Stable angina

Angina is a specific type of pain in the chest caused by inadequate blood flow through the blood vessels (coronary vessels) of the heart muscle (myocardium).

Angina, or angina pectoris, is temporary chest pain or a sensation of pressure that occurs when the heart’s need for oxygen is not satisfied by the amount of blood supplied to the heart. Blood flow can be limited when the arteries are narrowed by atherosclerosis, or because of coronary artery spasms. Symptoms of angina may also include discomfort in the shoulders, inside the arms, through the back and in the throat, jaw, or teeth. Angina due to atherosclerosis usually occurs during physical exertion or emotional distress, or at rest if the artery is narrowed by more than 70%.
