LIMA, Luciana M. et al. D-Dimer plasma levels in patients with coronary artery disease. Rev. Bras. Hematol. Hemoter. [online]. 2006, vol.28, n.4, pp.280-283. ISSN 1516-8484.  http://dx.doi.org/10.1590/S1516-84842006000400012.

We have previously reported that prothrombin fragment 1+2 levels were not associated to the presence or severity of coronary artery disease (CAD) and do not provide further information on subjects with CAD diagnosed by angiography. Thus, in the present study another marker of hypercoagulability was evaluated in the same subjects. This study aimed at determining D-Dimer plasma levels in a group of subjects undergoing coronary angiography to establish a likely relation between this parameter and the severity of CAD. D-Dimer plasma levels were determined in 17 subjects with no coronary atheromatosis (controls), 12 subjects with mild/moderate atheromatosis and 28 subjects with severe atheromatosis. No significant differences were observed among the three groups. Data analysis enables an inference on a tendency towards an increase in fibrinolytic activity in patients with atheromatosis, reflected by the increase in D-Dimer concentrations in the severe atheromatosis group in subjects with CAD diagnosed by coronary angiography.

Palavras-chave : D-Dimer; coronary artery disease; coronary angiography.
