Angina Pectoris | Johns Hopkins Medicine
www.hopkinsmedicine.org › angina-pectorisAngina pectoris—or simply angina—is chest pain or discomfort that keeps coming back. It happens when some part of your heart doesn't get enough blood and oxygen. Angina can be a symptom of coronary artery disease (CAD). This occurs when arteries that carry blood to your heart become narrowed and blocked because of atherosclerosis or a blood clot.
