What is angina pectoris? Angina pectoris is chest pain that's felt due to lack of blood flow to the heart muscle. Angina's most often caused by atherosclerosis, but may also be due to heart muscle growth. This video covers the pathophysiology of angina, as well as differentiates the three types: stable angina, unstable angina, and vasoplastic angina.
