Angina Pectoris

Angina pectoris or stable angina is the discomfort or chest pain which occurs due to stress or activity. This is a medical condition which arises due to poor flow of blood via blood vessels to the muscles of the heart. The heart muscles keep working all the time and hence require a constant flow of oxygen into it for efficient working. The coronary arteries provide the oxygen rich blood to the heart muscles. When the muscles of the heart work harder, more oxygen is required. The symptoms are then noticed when the coronary arteries are blocked or narrowed by clotting of blood or the hardening of the arteries.
