Chronic vasculitis is considered to be associated with future cardiovascular events. Here, we present major cardiovascular events (MACEs) in patients who underwent coronary computed tomography angiography (CCTA) for screening for coronary artery disease (CAD), and the association between MACEs and the inflammation marker pentraxin (PTX)-3 or highly sensitive C-reactive protein (hsCRP). The patients who underwent CCTA for the purpose of screening for CAD at Fukuoka University Hospital (FU-CCTA registry), 456 patients with suspected CAD or at least one cardiovascular risk factor were followed for up to 5 years. The levels of PTX-3 and hsCRP in blood were measured at the time of CCTA, and the patients were divided into two groups according to the presence (MACEs group) or absence (non-MACEs group) of MACEs. There were no differences in PTX-3 or hsCRP between the MACEs (−) and MACEs ( +) groups in all patients. A multivariate analysis related to the presence or absence of MACEs by logistic regression analysis of inflammation factors (PTX-3 and hsCRP) in addition to conventional risk factors as independent variables was performed. PTX-3 was a predictor of MACEs in males, whereas smoking, but not PTX-3, was a predictor of MACEs in females. PTX-3 could be a predictor of MACEs in males, but not females.
