text: Angina pectoris should be differentiated from a heart attack on the basis that angina only involves temporary loss of oxygenation and blood supply to a part of the heart while a heart attack means that a certain section of the cardiac muscle is infracted, or dies from the prolonged lack of blood and oxygen, so in effect, angina is not heart attack but it can definitely lead to it if not given prompt attention.
