Objective: To investigate the clinical effects of Mufangji Tang combined with Danhong injection in the treatment of chronic pulmonary heart disease at acute exacerbation stage. Method: The 130 patients with chronic pulmonary heart disease at acute exacerbation stage in recent years in our hospital were chosen and randomly divided into control group (65 patients) with Danhong injection and observation group (65 patients) with Mufangji Tang on the basis of conventional western medicine treatment. The clinical efficacy

traditional Chinese medicine(TCM) syndrome scores

cardiac function grading

levels of pulmonary function

blood gas analysis and blood rheology indexes before and after treatment of both groups were compared. Result: The clinical efficacy of observation group was significantly better than that of control group

with statistically significant difference (P<0.05). The TCM syndrome scores after treatment in observation group were significantly better than those of control group and those before treatment

with statistically significant difference (P<0.05). The cardiac function grading

levels of pulmonary function

blood gas analysis and blood rheology indexes after treatment in observation group were significantly better than those in control group and those before treatmentwith statistically significant difference (P<0.05). Conclusion: Mufangji Tang combined with Danhong injection in the treatment of chronic pulmonary heart disease at acute exacerbation stage can efficiently relieve clinical symptoms and signs

improve heart and lung functions and help to reduce the degree of blood viscosity.
