Lipoprotein-associated phospholipase A2 activity (aLp-PLA2) was associated with desphospho-uncarboxylated matrix Gla protein (dp-ucMGP) The patients in the top quartile of dp-ucMGP had three-fold increase of all-cause mortality, but no effect of high Lp-PLA2 activity was found. We may speculate, that pathophysiology of aLp-PLA2 involves also vascular calcification
