Main objective

Scope: Safety, Efficacy

To compare efficacy in patients treated with aspirin alone compared to combination therapy with fondaparinux and aspirin prior to early invasive strategy in patients with NSTEMI.

Secondary objectives 1

  1. To evaluate and compare the relative bleeding risk associated with the use of aspirin alone and in combination with fondaparinux prior to an invasive strategy in patients with NSTEMI
