Objective Serum FIB has been established as a predictor of cardiovascular events. The aim of this study was to investigate the relationship of FIB with acute coronary syndrome (ACS) and severity of the ACS. Methods A total of 692 patients with ACS who underwent a definite diagnosis were selected. Ninety-nine patients without coronary heart disease severed as control group. Detail information were recorded in age, gender, history of alcoholic, smoking, hypertension. All patients were detected in FIB and some other biochemical indicators levels. Use the correlation analysis to find the relationship of FIB with grace scoring. Results With the increase of Grace risk level and coronary artery lesions and myocardial ischemia,the levels of FIB were significantly increased (P < 0.05).The correlation analysis showed that Grace scores had a positive correlation with FIB in ACS patients. The logistic regression analysis showed the FIB was the most prominent predictors for ACS. The areas under the ROC curve of FIB were 0.87 which suggested that FIB had a higher predictive value of ACS. Conclusion The levels of serum FIB is closely related to criticality of ACS. For the ACS patients,higher levels of FIB indicated higher Grace scores. FIB level may have important clinical value in early risk stratification evaluation of prognosis and treatment options.

Objective To investigate the intensive atorvastatin therapy on B7-H4 in peripheral blood monocytes of patients with unstable angina PCI undergoing percutaneous coronary intervention. Methods 80 patients with unstable angina were randomized to pretreatment with intensive dose (80 mg/day ,n = 40) and conventional dose(20 mg/day,n=40)of atorvastatin. Peripheral blood were subsequently obtained prior to PCI,and 18 ~ 24 h after PCI. Peripheral blood serum level of IL-4,IL-10 and IFN-γ were quantified using enzyme-linked immunosorbent assays. Fluorescence-based quantitative real-time PCR was used to measure levels of periph-eral blood monocytes B7-H4 mRNA. Results Levels of IL-10 ,sB7-H4 and B7-H4 mRNA increased in patients of both groups after PCI. The increase in intensive dose group is more significant (P < 0.05). IL-4 and IFN-γ decreased in patients of both groups after PCI. The decrease in intensive dose group is more significant (P <0.05). Conclusion Intensive dose atorvastatin treatment improve post-PCI immune inflammation in patients with unstable angina,possibly by promoting the expression of B7-H4 in peripheral blood monocytes.
