The importance of age and statin therapy in the interpretation of Lp-PLA2 in ACS patients, and relation to CRP
View through Europeana Collections
C-reactive protein (CRP) is a marker of arterial inflammation while lipoprotein-associated phospholipase A2 (Lp-PLA2) is related to plaque instability. The aim of this study was to evaluate the correlation between the risk of unstable plaque presenting as acute coronary syndrome (ACS) and Lp-PLA2, and to assess the influence of statins on interpretation of Lp-PLA2. A total of 362 consecutive patients presenting to the emergency department (ED) with acute chest pain suggestive of ACS were evaluated by cardiologists as STEMI, NSTEMI, or unstable angina, and non- ACS. Serum biomarkers measured on admission: troponin I, Creactive protein (Abbott), and Lp-PLA2 (DiaDexus). Four groups were defined according to the final diagnos-; non- ACS/statin+. Lp-PLA2 was highest in ACS/statin- group; statins decreased Lp-PLA2 both in ACS and non-ACS of about 20 %. Lp- PLA2 was higher in ACS patients in comparison with non-ACS patients group without respect to statin therapy (p
