Dual antiplatelet therapy with acetylsalicylic acid (ASA, aspirin) and clopidogrel is of great importance for treatment following coronary stenting. Unfortunately the variable platelet inhibitory effectiveness compromises the antithrombotic benefit of dual antiplatelet therapy. The aim of this prospective single centre study was to reduce the low response incidence of dual antiplatelet therapy with ASA and clopidogrel based on a standardized therapy algorithm.
