RESUMO
OBJECTIVE@#To determine the relation between plasma tissue factor (TF) and serum angiotensin II(AngII) and the effect of different dosages of fosinopril on chronic heart failure(CHF).@*METHODS@#Thirty healthy controls and 35 CHF patients were recruited to observe AngII,TF, left ventricular ejection fractions(LVEF) and left ventricular end-systolic volume index (LVESVI) at baseline and 10 weeks after the treatment. The 35 patients were randomly assigned into 2 groups: A routine dosage fosinopril group received 10 mg once daily and a middle dosage group received 10 mg twice a day for 10 weeks.@*RESULTS@#Compared with the healthy controls, AngII,TF,and LVESVI significantly increased (P<0.01) and LVEF significantly decreased (P<0.01) in CHF patients. The TF was positively correlated with AngII(r=0.2491, P<0.01) in the patients. After the 10-week treatment with different dosages of fosinopril, AngII,TF,and LVESVI obviously decreased(P<0.05 or P<0.01) and LVEF significantly increased in the 2 groups (P<0.05 or P<0.01). The middle dosage group changed more than the routine dosage group (P<0.01).@*CONCLUSION@#TF is positively correlated with AngII in CHF patients. Fosinopril can greatly improve cardiac function and antagonize prethrobotic state,and the therapeutic effect improves with the dosage increase.
