The New York State Department of Health has approved Enzo’s new PLAQPRO® Lp-PLA2 Assay. This clinical cardiac marker is a strong addition to Enzo’s cardiac tests, including our comprehensive lipid panel, direct LDL, hsCRP and Troponin.
Lipoprotein-associated phospholipase A2 (Lp-PLA2) is produced by inflammatory cells and circulates primarily bound to low-density lipoprotein (LDL) and is to a lesser extent associated with high-density lipoprotein (HDL) in human plasma1. LDL oxidization is an early key event in the pathogenesis of atherosclerosis. Elevated Lp-PLA2 levels have been found in atherosclerotic plaques and rupture lesions. Unlike systemic inflammation biomarkers, such as high-sensitivity CRP or serum amyloid A (SAA), Lp-PLA2 is a specific biomarker for vascular inflammation and can serve as an independent risk marker for cardiovascular disease (CVD)2,3.
Heart disease is a leading cause of death in both men and women4. Often, a woman will have no symptoms of heart disease, yet, it is directly responsible for approximately 25% of female deaths in the US5.
