METHODS: A total of 111 patients with stable coronary artery disease, and 66 healthy subjects were enrolled in the study. Serum levels of lipoprotein-associated-phospholipase A2 (Lp-PLA(2)), high-sensitivity C-reactive protein (hs-CRP), and myeloperoxidase (MPO) were measured to compare patient and control groups. RESULTS: Baseline characteristics were similar between healthy and patient groups, with the exception of age. ANCOVA and log-transformed data of inflammatory biomarkers revealed that, Lp-PLA(2) (p < 0,001) and hs-CRP (p < 0,05) levels in all patient groups were significantly higher than in the control group. Conversely, there was no significant difference in MPO levels among groups. CONCLUSIONS: in stable CAD patients, serum Lp-PLA(2) levels are more compatible than hsCRP and MPO levels in the detection of coronary stenosis.PfizerPfizer; ServierServier; Astra ZenecaAstraZenecaThis study was supported by the drug companies Pfizer, Servier and Astra Zeneca. the Authors thank all of the companies that helped during this investigation
