was no significant difference in Copeptin， NT-proBNP， serum ACB value， whole blood viscosity， plasma viscosity， hematocrit， ESR and fibrinogen levels in 2 groups（P＞0.05）； after treatment， Copeptin， NT-proBNP， whole blood viscosity， plasma viscosity， hematocrit， ESR and fibrinogen levels in 2 groups were significantly lower than before， and observation group was lower than control group， while serum ACB value was significantly higher than before， and observation group was significantly higher than control group， the differences were statistically significant（P＜0.05）. CONCLUSIONS： Based on conventional treatment， Breviscapine injection can significantly improve the copeptin， NT-proBNp and IMA levels， and improve hemorrheology.
