I couldn't help myslef and peaked at the LEF article. Notice this deals with endothelial dysfunction, i.e. it could improve erections:
"PLACŪ Test Identifies Atherosclerotic Plaques Ready to Rupture
The PLACŪ test measures blood levels of an enzyme called lipoprotein phospholipase A2 (Lp-PLA2). The Lp-PLA2 enzyme unleashes a chain of harmful events culminating in endothelial dysfunction, which is a pathological abnormality in the blood vessel wall that sets the stage for atherosclerosis, plaque accumulation, and rupture.6
An elevated level of Lp-PLA2 may signal that an arterial plaque is susceptible to rupture, which could cause a clot to break loose, precipitating a heart attack or stroke"
