The risk of MI, complications, and death in unstable angina varies because of the broad clinical spectrum that is covered by the term unstable angina. The aggressiveness of the therapeutic approach should be commensurate with the individualized estimated risk.

Patients who present with new ST-segment deviation (≥1 mm) have a 1-year death or MI rate of 11%, compared with a rate of only 6.8% in patients with isolated T-wave inversion. [19]
