Angina is chest pain or discomfort caused when your heart muscle doesn't get enough oxygen-rich blood. It may feel like pressure or squeezing in your chest.

Abdominal angina is abdominal pain after eating that occurs in individuals with ongoing poor blood supply to their small intestines known as chronic mesenteric ischemia.
