angina pectoris

Angina pectoris is according to the American Heart Association the medical term for chest pain or discomfort due to coronary heart disease. The condition manifests as chest tightness, discomfort or pain, palpitations and is caused by a reduced supply of oxygen-rich blood to the heart muscle as a result of narrow or blocked arteries. The symptoms can radiate into other parts of the body, e.g. back pain, arm or lower jaw. In severe cases, patients may have a sense of fear of dying. It often occurs during labour or emotional excitement and can be relieved by resting. For some patients, it can also be induced by meals or in the cold season.
