Study information
| Study design | Open labelled clinical study with patients admitted for coronary angioplasty | 
|---|---|
| Primary study design | Interventional | 
| Secondary study design | Randomised controlled trial | 
| Study setting(s) | Not specified | 
| Study type | Treatment | 
| Scientific title | |
| Study objectives | 150 mg/day maintenance dose will increase the biological effect of clopidogrel in clopidogrel low responders | 
| Ethics approval(s) | This protocol has been approved by the ethics committee of the internal medicine department in November 2005 | 
| Health condition(s) or problem(s) studied | Cardiovascular outpatients | 
| Intervention | After a loading dose of clopidogrel (600 mg), patients will take a standard dose of clopidogrel 75 mg once a day for 15 days. At day 15, adenosine diphosphate (ADP) induced platelet aggregation and measurement of phosphorylated vasodilator-stimulated phosphoprotein (VASP-P) by a flow cytometric technique will be performed. If patients are clopidogrel resistant, they will receive 150 mg (2x75) once a day during the next 15 days. ADP-induced platelet aggregation and measurement of VASP-P will be performed at day 30.  |
