Angina pectoris, commonly referred to as angina, is a type of chest pain or discomfort that occurs when the heart muscle doesn’t get enough oxygen-rich blood. The most common cause of angina is coronary artery disease (CAD), which is a condition where the blood vessels that supply the heart become narrowed or blocked due to a buildup of plaque.
Ischemia is a medical condition that occurs when there is a lack of blood flow and oxygen to a particular organ or tissue in the body. In the case of angina pectoris, ischemia occurs in the heart muscle due to a narrowing or blockage of the coronary arteries that supply blood to the heart. So, while angina pectoris is a specific type of chest pain that occurs due to ischemia in the heart muscle, ischemia can occur in other parts of the body as well, such as the brain or limbs.
