Objective: The purpose is to discuss the clinical effects of traditional Mongolian medicine to treat chronic cardiac failure(CHF) and influence of hemorheology

plasma D-dimer on patients. Method: One hundred and eight cases of patients with were randomly divided into control group (54 cases) and observation group (54 cases).In control group

patients were treated with western medicine conventional therapy by cardiac

diuresis

vascular dilation and so on. In observation group

besides based on control group

patients added traditional Mongolian medicine

Dali-16 wei san 5 g

taken orally after breakfast;Jili-3 wei decoction 5 g

taken orally after lunch;Shaosha-7wei pill 3 g

taken orally before sleep.Both groups were treated for 12 weeks.Record New york heart association(NYHA) cardiac functional grading and Lee's heart failure scores before and after treatment.Measure the left ventricular ejection fraction (LVEF)

left ventricular end diastolic diameter(LVDD) and cardiac output(CO) by ultrasonic cardiogram at pretherapy and post-treatment.Detect hemorheology

plasma D-dimer and N-terminal plasma brain natriuretic peptide precursor (NT-proBNP)before and after treatment. Result: After treatment

the total effective rate of the observation group was 87.4% superior to 70.37% of the control group(P<0.05). the Lee's heart failure scores of the observation group were lower than the control group(P<0.01)

Left ventricular end diastolic dimension(LDVV) of the observation group was lower than the control group(P<0.05)

LVEF and CO of the observation group were higher than the the control group(P<0.01). The level of NT-proBNP and D-dimer of the observation group were lower than the control group(P<0.01). The improvement of blood viscosity

erythrocyte deformation index(RCD) and fibrinogen of the observation group were superior to the control group(P<0.05). Conclusion: Based on the routine western medicine therapy

for the elderly patients

it can improve the cardiac function

relief clinical symptom and improve clinical effects when Dali-16 wei san

Jili-3 wei decoction and Shaosha-7 wei pill of the three traditional Mongolian medicine were used in CHF.Besides

it can also improve the hemorheology and hypercoagulable state

worthy of clinical using.
