Long-term antithrombotic therapy with oral anticoagulants or antiplatelet agents for survivors of acute myocardial infarction (AMI) is widely prescribed and has been evaluated in many clinical trials.1 An overview in 19702 suggested a modest benefit of anticoagulation therapy, but—although oral anticoagulants have been widely used in some European countries—their use in North America is limited. More recently, the Sixty Plus,3 Warfarin Re-infarct Study,4 and the Anticoagulants in the Secondary Prevention of Events in Coronary Thrombosis (ASPECT)5 trials have all shown statistically significant reductions of clinically important vascular outcomes by anticoagulant treatment compared with placebo.

In this issue of JAMA, van Bergen et al6 report on an economic analysis of anticoagulant treatment in the Netherlands that exemplifies the rather unusual win-win situation of increased efficacy and reduced cost. The ASPECT study randomized 3404 patients within 6 weeks of their AMIs to
