metabolised by CYP2C9, suggests that our results are not likely
to be explained by drug-drug interactions. In addition, differences
in lipophilicity of statins are also unlikely to account for the
differences found between statins as rosuvastatin is hydrophilic
while simvastatin is lipophilic. A potential other explanation is
that statins do reduce coagulation, which was suggested by
Sahebkar et al. because D-dimer levels decreased after 3 months
of statin therapy and because D-dimer levels are markers of
coagulation [14]. To get more insight whether simvastatin and
rosuvastatin have anticoagulant properties, a next step would be
to investigate the effect of these statins on coagulation in patients
not on VKAs.
