Angina is chest pain or discomfort caused by reduced blood flow to heart muscle (myocardial ischemia). It's typically triggered by physical exertion or emotional stress. Unlike myocardial infarction, angina pain is temporary and resolves with rest or medication. It's often described as pressure, squeezing, or burning sensation in the chest.
