Some people who have heart attacks do not experience chest pain, although most do. A study of people admitted to emergency rooms with heart attacks compared the death rates of people who had chest pains with those of people who had less typical symptoms. Of the 19,118 people who had heart attacks with chest pain, 822 died.
