The mean platelet volume (MPV) values reflect platelet size and are accepted as marker of
platelet activation. We sought to test the hypothesis that platelet activation occurs …

Background: In this study, we investigated the clinical importance and possibility of mean
platelet volume to be a predictive marker for acute mechanical valve thrombosis. Methods …

The incidence of thromboembolism is higher in mitral regurgitation. Mean platelet volume
(MPV), which is calculated automatically in the complete blood count tests, indicates platelet …

Systemic thromboembolism is a serious major complication in patients with mitral stenosis.
However, the pathogenesis of thromboembolism in mitral stenosis is not fully understood …

Because thromboembolic pathogenesis in mechanical prosthetic valves (MP) might involve
selective MP platelet consumption with consequent reduced platelet survival, it has been …

In vivo platelet reactivity, expressed by plasma concentration of p-thromboglobulin (PTG)
and platelet factor 4 (PF4), was determined in 57 patients with bioprosthetic heart valves: 35 …

We have studied the platelet count and the megathrombocyte index (MI), or percentage of
platelets that have a diameter greater than 2.9 pm, in 100 patients with valvular heart …

Methods: The procoagulant activity of platelets was measured using a real-time assay of
platelet activation state (PAS), which was based on a modification of the prothrombinase …

Platelets play an important role in the genesis of thromboembolic episodes frequently
observed in patients following cardiac valve replacement. No simple and reliable method as …

The effect of percutaneous mitral valvuloplasty (PMV) on markers of coagulation and platelet
activation was investigated to assess whether coagulation or platelet activation take place …
