Lipoproteina(a) e fosfolipidi ossidati sono associati all'inflammazione miocardica dopo infarto miocardico acuto.

Localized myocardial inflammation after acute myocardial infarction (MI) is regulated by innate immune pathways. Oxidized phospholipids (OxPLs) carried on lipoprotein(a) (Lp(a)) are proinflammatory, but their association with myocardial inflammation during the early post-MI period has not been described. Here we study patients enrolled in a randomized, double-blind trial of in-hospital PCSK9 inhibition versus placebo, in whom this treatment decreased myocardial inflammation after MI. We analyze plasma levels of OxPLs on apolipoprotein B-100 containing lipoproteins (OxPL-apoB), OxPLs on apolipoprotein(a) (OxPL-apo(a)), and Lp(a) during hospital admission and at 30 days, and paired [18F]-fluor
