Intervention / Treatment |
---|---|
Experimental: aspirin, clopidogrel
If the treatment with aspirin and/or clopidogrel is insufficient (platelet function testing) the dose was increased or the drug was changed (clopidogrel to ticlopidine or prasugrel)
|
ASA 100 mg, ASA 300 mg, ASA 500 mg Clopidogrel 75 mg, Clopidogrel 150 mg, Ticlopidine 2x 250 mg, Prasugrel 10 mg. Intervention List: In the case of clopidogrel low-response, the maintenance dose was doubled (repeated loading dose followed by 150 mg daily), and when still ineffective ticlopidine or prasugrel, if available and not contraindicated, were used. ASA low-responders were treated by increasing the dose to 300 mg in a first step or to 500 mg ASA when the first modification was not sufficient.

Measure Description |
Time Frame |
---|---|---|
Number of Participants Who Were Responders or Low-Responders of Antiplatelet Therapy as a Result of Whole Blood Aggregometry Testing (See Outcome Measure Description)
Time Frame: 2 years
|
In patients treated with aspirin and clopidogrel aggregometry was performed and depending on the results the patients were either responder or low-responder of antiplatelet therapy. The following definitions were used for clopidogrel low response (CLR: >5 ohm when stimulated with adenosine diphosphate (ADP) 5 μM) and ASA low response (ALR: >0 ohm;stimulated with arachidonic acid 10 μM) with the ChronoLog 590 aggregometer. In the case of low-response alternative antiplatelet therapy was modified according to the study plan (see protocol section). |
