Abstract
- Abstract: Oxidative stress may play a role in the development of atherosclerosis. The purpose of the present study was to explore the relationship between 8-isoprostaglandin F2α (8-iso-PGF2α) levels and the presence of coronary artery disease (CAD) and to also clarify whether 8-iso-PGF2α might add independently to measures of CAD extent. The study group consisted of 241 consecutive patients who were undergoing coronary angiography for suspected CAD. 8-iso-PGF2α levels were recorded for all participants. The analysis revealed a significant difference in 8-iso-PGF2α levels in patients with and without hypertension (P <0.001), in patients with diabetes relative to nondiabetic patients (P <0.05), and in males respect to females (P <0.001). A significant positive correlation was found between age and 8-iso-PGF2α levels (P <0.001). 8-iso-PGF2α levels correlated with the number of cardiovascular risk factors (P <0.001). 8-iso-PGF2α levels were higher in the CAD(+) respect to the CAD(−) groups (337.7±80.2 and 263.8±74.2pg/ml and P <0.001). A stepwise elevation in the 8-iso-PGF2α levels was found depending on the number of affected vessels (P <0.001). The 8-iso-PGF2α levels showed a significant positive correlation with the numbers of >50 and >25% stenotic segments (P <0.001) and the extent score of coronary stenosis (P <0.001). The multivariate logistic regression analysis indicated 8-iso-PGF2α as an independent factor associated with CAD (odds ratio, 2.47 and P =0.001). The results suggested that 8-iso-PGF2α is associated with the presence of CAD in patients undergoing coronary angiography and is also related to the extent of coronary stenosis in Chinese population.
