Nitroglycerin and aspirin administration may also improve the pain. One distinguishing factor of unstable angina is that the pain may not completely resolve with these reported relieving factors. Also, many patients will have already have coronary artery disease. This may be either established coronary artery disease or symptoms they have been experiencing for some time. These patients may have familiarity with the symptoms and may report an increase in episodes of chest pain that takes longer to resolve and an increase in the severity of symptoms. These symptoms indicate unstable angina as the more likely diagnosis, as opposed to stable angina or other causes of chest pain.
