Objective To explore the clinical characteristics and the long-term prognosis of type 2 cardiorenal syndrome（ CRS） patients with blood-stasis pattern. Methods 390 cases eligible were divided into CRS group and non-CRS group. After comparing TCM pattern elements between the two groups

we collected the related clinical data. Then all patients were followed-up for 1 810 days to get their final events（ survive or dead）. Using ROC curves plotted based on the relationship between renal function and long-term prognosis

patients were re-assigned into renal function level groups to try to find out the distribution of TCM pattern and the relationship of blood-stasis pattern with renal function or with modern medical indices. Results Blood-stasis pattern was positive correlated with renal function of chronic heart failure（ CHF） patients（ P = 0. 027）

but was negative correlated with qi deficiency pattern or yang deficiency pattern

maybe due to the progression of CRS. Conclusion The important effect of blood-stasis pattern on the occurrence and development was proved

and the blood-stasis pattern may indicate the deterioration

dysfunction of heart leading to dysfunction of kidney.
