Abstract

The tendency of a plasma sample to generate thrombin, a central enzyme in blood coagulation, might be an important indicator of prothrombotic risk linked to cardiovascular disease (CVD), but the presence of platelets may be a critical determinant. Clinical data, laboratory markers and thrombin generation (TG), investigated in both platelet-rich plasma (PRP) and platelet-free plasma (PFP) at 1 pM TF, were available in 407 individuals from the Gutenberg Health Study. Given the well-known effect of anticoagulants on TG, subjects taking anticoagulants (n = 15) have been excluded resulting in 392 subjects for further analysis. Lag time, endogenous thrombin potential (ETP) and peak height were the investigated parameters of a TG curve. Multivariable linear regression analysis was used to identify TG determinants. Mean platelet volume (MPV) and platelet count were both negatively associated to lag time and positively to peak height (MPV, beta: 6.35 [2.66; 10.0]; platelet count, beta: 0.111 [0.054; 0.169]) in PRP only. C-reactive protein was positively associated with lag time and ETP in both PRP and PFP, with a stronger effect on ETP in PRP (PRP, beta: 76.7 [ 47.5; 106]; PFP, beta: 34.8 [10.3; 59.2]). After adjustment for fibrinogen, the relation between CRP and ETP was attenuated in PRP and PFP. Of the traditional cardiovascular risk factors (CVRFs), obesity was positively associated to TG in PRP only. Our findings support that TG, particularly in PRP, relates to traditional CVRFs in a representative sample from a population-based study. Assessment of procoagulant activity in a platelet-dependent manner by TG is a promising tool for assessing individual risk for CVD.
