Unstable angina describes a syndrome that is intermediate between stable angina and myocardial infarction (heart attack): it is characterized by an accelerating or "crescendo" pattern of chest pain that lasts longer than in stable angina, occurs at rest or with less exertion than in stable angina, or is less responsive to medication. Unstable angina and myocardial infarction are considered acute coronary syndromes , while stable angina is a chronic condition.
