Objective To explore the clinical characteristics and the long -term prognosis of type 2 car-diorenal syndrome (CRS)patients with blood-stasis pattern.Methods 390 cases eligible were divided into CRS group and non-CRS group.After comparing TCMpattern 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 e-vents (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 distri-bution of TCMpattern and the relationship of blood-stasis pattern with renal function or with modern med-ical 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 defi-ciency 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 de-terioration,dysfunction of heart leading to dysfunction of kidney.
