Abstract:
Objective To study the difference in fibrinogen and D-dimer between the patients with ST-ele-vation myocardial infarction (STEMI) and those with normal angiography of coronary artery.Methods 100 patients with STEMI who underwent PCI and 100 patients with normal coronary arteriograms as controls from Jan.2005 to Dec.2007 were studied.Plasma concentrations of fibrinogen and D-dimer were compared.Results There was no significant difference in gender, age, history of hypertension and diabetes and smoking between the two groups.Plas-ma concentration of fbfinogen(Fg) was higher in control group [(2.65±0.68 )g/L ] than STEMI group [(2.38±0.91)g/L] (P<0.05).The square root of plasma concentration of D-dimer was higher in STEMI group [(13.23±5.08) μg/L] than control group [(9.40±5.03)μg/L ] (P<0.01).The square root of the rate between D-dimer and fibrinogen was higher in STEMI group (9.11±4.13 ) than control group (5.92±3.35 ) (P<0.01).Conclusion The levels of fibrinogen in patients with STEMI are significantly lower than that of control group, and D-dimer is higher in the former group than in the latter group, suggesting that fresh thrombosis and secondary fibrinolysis exit in STEMI patients at the acute stage.
