Angina Pectoris
Angina Pectoris, symptom of reduced oxygen supply to the heart muscle, usually caused by narrowing or obstruction of the coronary artery. It is marked by a viselike squeezing sensation beneath the breastbone. Pain may radiate from the front of the chest, often into the arm. The attacks usually last several minutes. They may be caused by emotional stress but are more likely to result from physical activities that require an increased supply of blood to the heart. The disease occurs most commonly in middle-aged and older people, particularly those who suffer from arteriosclerosis. Relief is obtained by rest and relaxation. Patients can be treated with drugs that relax and dilate blood vessels or that slow the heart, and surgery can be performed to improve coronary circulation. The attacks themselves cause no damage.
