What are the characteristics of angina?
The characteristics of angina include deep, poorly localized chest or arm pain that is reproducibly associated with exertion or emotional stress. It is relieved promptly (ie, in <5 minutes) with rest and/or short-acting nitroglycerin. Patients with NSTE-ACS may have typical or atypical anginal symptoms, but episodes are more severe and prolonged, may occur at rest, or may be precipitated by less exertion than the patient previously experienced.
