title: Adjuvants to thrombolysis after acute myocardial infarction. Does adding antiplatelet agents, antithrombotics, or angioplasty make a difference?
abstract: Thrombolytic therapy markedly reduces mortality and improves left ventricular function in patients with acute myocardial infarction. Improvement may be even more substantial with adjuvant therapy. Aspirin has proved to be effective adjuvant therapy to thrombolysis. Other antiplatelet agents that may be even more effective or have an additive effect with aspirin are being studied. The role of antithrombotic agents, especially heparin, as adjuvant therapy remains unclear. Immediate cardiac catheterization with angioplasty has been used as adjunct therapy, but its routine use is not recommended. Instead, elective angioplasty (cardiac catheterization, with revascularization as indicated) should be undertaken in patients with recurrent ischemia. Angioplasty as an alternative to thrombolysis may be advantageous in certain patients, such as those presenting in cardiogenic shock or with contraindications to thrombolysis. The role of primary angioplasty in other groups (eg, the elderly, those with anterior myocardial infarction) remains unclear, and further trials are necessary before it can be recommended over thrombolytic therapy. Equipment needed for angioplasty limits its practicality, whereas thrombolytic therapy can be administered at most US hospitals.
