Introduction
Among other lipid related biomarkers, lipoprotein-associated phospholipase A2 (Lp-PLA2) and type II secretory phospholipase A2 (sPLA2) represent emerging candidates for refined assessment of future cardiovascular disease (CVD) risk. Indeed, emerging evidence from more than prospective 15 studies conducted since 2000, clearly demonstrate the prognostic ability of increased Lp-PLA2 concentrations or elevated activity for risk of future coronary heart disease (CHD) and stroke. Moreover, Lp-PLA2 might have similar predictive power for both, incident CHD in initially healthy subjects, as well as for recurrent events in those with clinically manifest atherosclerosis.
Discussion
By contrast, to date, there are only few prospective studies that have investigated the relationship of sPLA2 with future CVD risk. However, most of them show a positive association between increased mass or elevated activity and future atherosclerotic complications. Nonetheless, since inhibitors of Lp-PLA2 and sPLA2 have already been developed, these enzymes may be considered as novel therapeutic targets to treat residual risk in certain high risk patient groups.
Conclusion
This review summarizes the epidemiologic evidence on the association between increased mass or elevated activity of these two phospholipases and risk of CVD.
