Pentraxin 3 as a biomarker for acute coronary syndrome: comparison with biomarkers for cardiac damage.

Abstract:

BACKGROUND:Pentraxin 3 (PTX3) is increased in circulating blood during the acute stage of acute coronary syndrome (ACS). Therefore, we compared diagnostic values of PTX3 for ACS with those of biomarkers for myocardial damage, such as troponin T (TnT) and heart-type fatty acid binding protein (H-FABP). METHODS AND RESULTS:Patients (n = 87) undergoing coronary angiography (CAG), consisting of 16 ACS and 71 non-ACS patients were enrolled. Non-ACS consists of 12 patients with normal CAG, 30 stable angina pectoris (SAP) patients controlled by medical treatment, and 29 SAP patients who required elective coronary revascularization (percutaneous coronary intervention or coronary artery bypass graft). Age, gender, or prevalence of diabetes, hypertension, or smoking was not significantly different between ACS and non-ACS groups. Serum total, high-density lipoprotein, or low-density lipoprotein cholesterol, or triglyceride levels were not significantly different between ACS and non-ACS. PTX3 levels were not significantly correlated with lipid profiles or different between those with and without conventional risk factors. Circulating PTX3, TnT, and H-FABP levels were significantly higher in ACS than non-ACS. In receiver-operating characteristic (ROC) curves, area under the curve (AUC) values for PTX3, TnT and H-FABP were 0.920, 0.674, and 0.690, respectively. ROC curves of PTX3 (AUC: 0.901), TnT (AUC: 0.731), and H-FABP (AUC: 0.633) for ST-elevation ACS were similar to those for whole ACS. In a TnT-negative subgroup, the AUC values of PTX3 and H-FABP for ACS were 0.981 and 0.489, respectively. CONCLUSIONS:PTX3 is a sensitive and specific biomarker for the diagnosis of ACS, and shows additional diagnostic values when measured in combination with TnT.
