Importance of silent myocardial ischemia in therapy for unstable angina pectoris

  • W. Rafflenbeul
Conference paper

Abstract

In the spectrum of acute ischemic syndromes, unstable angina pectoris is characterized by specific features in the patients history, including recent occurrence of angina at rest, or brought on by minimal exertion, as well as the deterioration of a chronic stable angina into more severe, prolonged or more frequent anginal attacks (crescendo angina). Typical electrocardiographic criteria include reversible ST-segment deviations and/or variable T-wave inversions. Cardiac enzymes are usually not elevated.
