ReviewOptimal treatment of patients with acute coronary syndromes and non-ST-elevation myocardial infarction.
Non-ST-elevation myocardial infarction is usually indistinguishable from unstable angina at the initial presentation. The diagnosis is made subsequently when cardiac enzymes are found to be elevated either at admission or within 18 hours. Our understanding of the pathophysiology of acute coronary syndromes has advanced dramatically, and coupled with this understanding has been the introduction of new antiplatelet and antithrombotic treatments. ⋯ Patients at intermediate risk should be treated with aspirin, unfractionated or low-molecular-weight heparin and, if unfractionated heparin is chosen, an adjunctive IIb/IIIa receptor antagonist. Patients at high risk should be treated with the same therapies and considered for expeditious angiography and revascularization as appropriate. A long-term secondary prevention strategy should be implemented.
