Inhibition of platelet aggregation by aspirin ...

Objectives We sought to investigate, during a two-year follow-up period, the effects of aspirin on platelet aggregation. Background The platelets of patients given aspirin may be less sensitive to antiplatelet treatment, although the extent of such phenomenon over long-term follow-up is unclear. Methods Adenosine diphosphate (ADP) and collagen-induced platelet aggregation was periodically ...

Platelet Function Testing: Light Transmission Aggregometry

Principles of Light Transmission [Born] Aggregometry. Platelet aggregation testing measures the ability of various agonists to platelets to induce in vitro activation and platelet-to-platelet activation. Classically Born aggregometry uses platelet rich plasma [PRP] but whole blood aggregometry can be also used.

Antiplatelet effects of clopidogrel compared with aspirin ...

We sought to compare the inhibitory effects of the combination of two doses of aspirin plus clopidogrel with either drug alone on platelet aggregation and activation. BACKGROUND. Enhanced platelet inhibitory effects of clopidogrel by aspirin on platelet aggregation and activation are suggested by experimental studies but have not been shown in ...

Comparison of a New P2Y12 Receptor Specific Platelet ...

Background Clinical studies suggest that 10-50% of patients are resistant to clopidogrel therapy. ADP induced platelet aggregation, a widely used test to monitor clopidogrel therapy, is affected by aspirin and is not specific for the P2Y12 receptor inhibited by clopidogrel. Objectives To develop a P2Y12-specific platelet aggregation test and to compare it with other methods used for monitoring ...

Platelet Aggregometry Interpretation | The Fritsma Factor

They also depend upon functional platelet activation pathways, so a membrane receptor defect or a platelet activation pathway defect, which is also called a secretion defect or aspirin-like disorder can result in no aggregation. You'll need to compare to arachidonic acid and collagen results to sort out the differences, and ensure the patient ...

Platelet - Wikipedia

Platelets secrete thromboxane A2, which acts on the platelet's own thromboxane receptors on the platelet surface (hence the so-called "out-in" mechanism), and those of other platelets. These receptors trigger intraplatelet signaling, which converts GPIIb/IIIa receptors to their active form to initiate aggregation. Granule secretion

Platelet aggregation can be analyzed using platelet agonists in aggregometers. Platelet adhesion and aggregation in response to agonists can also be evaluated using platelet function analyzers (PFA). Platelet aggregation. This is mediated primarily by fibrinogen, which binds to the activated fibrinogen receptor (GPIIb/IIIa) on platelets.
