Angina pectoris, or simply angina, is chest pain that's due to lack of oxygen getting to your heart muscle, and so the heart is receiving some oxygen, but not enough to function properly, and this angina is something that may or may not occur before someone has a heart attack, so some heart attacks occur with angina and some heart attacks occur without it. Another related term is ischemia, and here we're just talking about a shortage of blood flow to the heart.
