The objectives of the study was to compare the newer inductor of platelet aggregation cationic propyl gallate (CPG) with adenosine diphosphate (ADP) for the examination of aspirin (ASA) effectivity with optical aggregometry. 116 patients with a stable cardiovascular disease, taking ASA 100mg/day for 3 1 month were investigated. Cationic propyl gallate is an optimal inductor for optical aggregometry to monitor laboratory effectiveness of aspirin therapy in routine clinical pratice.
The determined high prevalence of laboratory aspirin ineffectiveness highlights the clinical importance of the problem
