Core Tip

Core Tip: Two hundred and forty-nine patients with acute coronary syndrome were enrolled in the study. Lipoprotein(a) [Lp(a)] levels were measured before percutaneous coronary intervention (PCI) to 48 h after using an isoform-independent assay. Lp(a) levels decreased significantly from pre-PCI (0 h) to 12 h after, and then increased up to 48 h after. The changes from 0 to 12 h [Lp(a)Δ0-12] were significantly correlated with basal creatinine and Lp(a). Among the tertiles classified according to the changes from 0 to 12 h [Lp(a)Δ0-12], major adverse cardiac events (MACE) were significantly more frequent in the lowest Lp(a)Δ0-12 group than in the other two groups. Multivariate analysis revealed that Lp(a)Δ0-12 and basal creatinine were independent determinants of subsequent MACE.
