The contemporary management of acute myocardial infarction continues to evolve rapidly. The ultimate goal of therapy is timely, complete, and sustained myocardial reperfusion. There is a powerful time-dependent effect on mortality, and thus the balance between the time and likelihood of maximal reperfusion is crucial in deciding whether to use primary percutaneous balloon angioplasty or thrombolysis as the initial reperfusion strategy. ⋯ Combination therapy with low-dose fibrinolytics, glycoprotein IIb/IIIa inhibitors, and low molecular weight heparin, with or without subsequent early planned percutaneous coronary interventions, may provide the optimal strategy for maximal coronary reperfusion, but the results of large, randomized mortality trials currently underway need to be analyzed. Risk stratification will continue to play a major role in determining which patients should receive a specific therapy. The care of the patient with an acute myocardial infarction will continue to be a challenge requiring the proper selection from the vast pharmaceutic and interventional options available.

ReviewAntithrombotic and thrombolytic therapy in acute cardiac care.
This article explores the use of antithrombotic and thrombolytic therapy in acute cardiac care, and looks at traditional anticoagulant agents, newer antithrombin agents, thrombolytic agents, and others.

Patients with decompensated heart failure should be managed in an aggressive and proactive manner, using predominantly hemodynamic and end-organ function goals. This management is in contrast to the chronic maintenance therapy of patients with heart failure, where a neuroendocrine approach is indicated. Underlying anatomic targets for intervention should be sought aggressively and addressed. Patients who prove resistant to standard measures should be considered for early referral to heart transplant centers for more definitive measures, including evaluation for heart transplantation and mechanical circulatory support if necessary.

The field of percutaneous coronary intervention continues to progress at a tremendous rate. Advances in techniques, in device technology, and in adjunctive therapy have increased significantly the number of patients who may benefit from angioplasty and have increased the early and long-term success rates of these procedures. Future progress in radiation therapy, IIb/IIIa inhibitors, stent design, and other novel approaches undoubtedly will offer further improvements in the capability of coronary interventions to help patients live longer and feel better.
