Angina is temporary chest pain or a sensation of pressure that occurs while the heart muscle is not receiving enough oxygen.
A person with angina has discomfort or pressure beneath the breastbone (sternum).
Angina typically occurs in response to exertion and is relieved by rest.
Doctors diagnose angina based on symptoms, electrocardiography, and imaging tests.
Treatment may include nitrates, beta-blockers, calcium channel blockers, and percutaneous coronary intervention or coronary artery bypass graft surgery.
In the United States, about 10 million people have angina, and it is newly diagnosed in about 500,000 people each year. Angina tends to develop in women at a later age than in men.
