Background: Lipoprotein-Associated Phospholipase A2 (Lp-PLA2) has been shown to be a highly specific biomarker for artery inflammation and for cardiovascular risk assessment. Coronary artery calcification defined as coronary artery calcium score (CAC score) is a marker of increased risk of coronary artery disease (CAD).

Aim: This study evaluates the association between Lp-PLA2 and presence of coronary artery calcification among patients with low and intermediate probability of CAD.

Methods: The analysis included 305 consecutive patients (61.3±10.59 yrs; 41.3% males) with intermediate probability of CAD. All patients were routinely assessed for traditional risk factors of CAD. Serum Lp-PLA2 mass was measured by ELISA-based method. CAC score was obtained by multi-detector computed tomography and calculated by Agatston method. Coronary artery calcification was defined as CAC score>0.

Results: Clinical characteristic of study population is summarized in the table. Coronary artery calcification was found in 187 (61.3%) patients (63.76±9.94 yrs; 48.7% males). In univariate analysis the predictors of coronary artery calcification were age (OR 1.07, 95%CI 1.04–1.09, p<0.0001), male gender (OR 2.42, 95%CI 1.38–3.66, p=0.0011), hypertension (OR 4.76, 95%CI 1.26–18.06, p=0.0217), diabetes (OR 4.28, 95%CI 1.37–13.36, p=0.0123), Lp-PLA2 (OR 1.008, 95%CI 1.0006–1.014, p=0.0325), eGFR (OR 0.97, 95%CI 0.955–0.99, p=0.0042), triglycerides (OR 1.55, 95%CI 1.03–2.32, p=0.0362). In multivariate analysis age (OR 1.08, 95%CI 1.02–1.12, p=0.0055) and Lp-PLA2 (OR 1.02, 95%CI 1.004–1.03, p=0.01) were the only independent predictors of coronary artery calcification.

Conclusions: Plasma Lp-PLA2 is independently related to coronary artery calcification which supports its potential clinical utility in identification of individuals at increased risk of CAD.
