RESUMEN
The use of coronary stents has become routine in interventional cardiology, for which anti-platelet drugs are part of the daily antithrombotic routine. The association of ticlopidine and aspirin may be replaced definitively by that of clopidogrel and aspirin. A rapid biological test of the efficacy of these thienopyridines would allow identification of possible drug resistance. The anti-GP IIb/IIIa agents with an immediate onset of action are also widely used in the acute phase of MI and in acute coronary syndromes without ST elevation when the troponin levels could enable selection of high risk patients more likely to benefit from an aggressive antithrombotic strategy. Finally, the superiority of enoxaparin over unfractionated heparin must be emphasised in these same acute coronary syndromes.
