Platelet Activity Indices in Patients With Deep Vein Thrombosis

Abstract

BACKGROUND: Extensive research has been performed regarding the association between platelet activity indices and various cardiovascular disorders. Less clear data, however, are present between these indices and deep vein thrombosis (DVT). AIM: The aim of this study was to investigate the association between platelet activity indices and DVT in a relatively large population. METHODS: Mean platelet volume (MPV), mean platelet mass (MPM), and mean platelet component (MPC) were measured by an autoanalyzer in a total of 203 patients with DVT and the results were compared with 210 age- and sex-matched controls without DVT. RESULTS: There were significant differences between the study and control groups in MPV (8.6 ± 1.3 fL vs 7.9 ± 0.5 fL [95% CI -0.82 to -0.44], P < .001, respectively), MPM (2.2 ± 0.3 pg vs 2.0 ± 0.1 pg [95% CI -0.20 to -0.11], P < .001, respectively), and MPC (24.9 ± 3.2 g/dL vs 26.3 ± 1.6 g/dL [95% CI 0.91 to 1.89], P < .001, respectively). These 3 platelet activity indices were also found to be significant predictors of the presence of DVT (all Ps < .001). CONCLUSION: In patients with DVT, the presence of DVT was closely associated with increased platelet activation. The MPV, MPM, and MPC may identify patients requiring aggressive antiplatelet treatment.
