title: Optimizing the Treatment of Unstable Angina.
abstract: Unstable angina and non--Q-wave myocardial infarction (MI) are at the center of the spectrum of myocardial ischemia, which ranges from stable angina to acute Q-wave MI. In addition to clinical evaluation, cardiac specific markers such as troponin T or I can assist in early diagnosis, triage, and risk stratification. Antithrombotic therapy with aspirin and heparin have been shown to improve the outcome of patients with acute ischemic syndromes. Thrombolytic therapy does not appear to be beneficial in these syndromes. Antiischemic therapy remains an important component of the overall therapy. A strategy of early coronary angiography and revascularization leads to a similar long-term outcome as compared with a more conservative strategy of revascularization for recurrent ischemia, but the early invasive strategy is more expeditious as a large number of conservatively treated patients have recurrent ischemia. At present, many new antithrombotic agents are under active investigation, with the hope that they will lead to further improvement in the clinical outcome of patients with acute ischemic syndromes.
