Objective To evaluate clinical curative effect and safety of Fulvning Granule as an adjuvant therapy in treating 30 cases of chronic heart failure with arrhythmia with Qi and Yin deficiency. Methods Sixty cases of chronic heart failure with arrhythmia with qi and yin deficiency according to Chinese Medicine syndrome differentiation were randomly divided into a treatment group and a control group

with 30 cases in each. Control group was given Western medicine standardized treatment

while treatment group used Fulvning Granule additionally on the base of the treatment of control group

15 g each time

twice a day. Courses of the treatment of two groups were both 4 weeks.The New York Heart Association（ NYHA） cardiac functional grading

Six-Minute Walk Distance

cardiac color ultrasound

dynamic electrocardiogram

Minnesota Living with Heart Failure Questionnaire（ LHFQ） scores（ including physical

emotional

economic

and social items）

traditional Chinese medicine（ TCM） syndrome scores

and treatment safety of patients in two groups were observed. Then

the curative effect on cardiac function and arrhythmia was evaluated. Results Curative effects on cardiac function（ the total effective rates was 76. 67% in treatment group

and 50. 00% in control group） and arrhythmia（ the total effective rates was 66. 67% in treatment group

and30. 00% in control group） in two groups after treatment were significantly different（ P < 0. 05 or P < 0. 01）. Treatment group was superior to control group. After treatment

TCM syndrome scores

LHFQ physical

economic

and social scores

as well as the total LHFQ scores decreased

while Six-Minute Walk Distance increased in both groups（ P < 0. 01）

especially in the treatment group（ P < 0. 05）. There was no statistically significant difference in all indexes of cardiac color ultrasound between two groups before and after treatment（ P > 0. 05）. Conclusion As an adjuvant therapy for chronic heart failure with Qi and Yin deficiency

Fulvning Granule can improve cardiac function and quality of life effectively and safely.
