Therapeutic effect of continuous renal replacement therapy on different types of cardiorenal syndrome / 心血管康复医学杂志

ABSTRACT

Objective:To observe therapeutic effect of continuous renal replacement therapy (CRRT ) on different types of cardiorenal syndrome (CRS) .Methods :According to patient′s conclition ,a total of 247 CRS patients were divided into type 1 group (n=47) ,type 2 group (n=51) ,type 3 group (n=55) ,type 4 group (n=49) and type 5 group (n=45) .All patients received CRRT ,echocardiography and plasma level of N terminal pro B type natriuretic peptide (NT‐proBNP) detect to evaluate cardiac function status ;the 24h urine volume and endogenous creatinine clearance rate (Ccr) were measured to assess renal function status before and after treatment . Results:Compared with before treatment ,on one week after CRRT ,LVEF ,urine volume and Ccr level significantly rose ,NT‐proBNP level significantly reduced ( P<0.05 or <0.01) .Compared with type 4 and 5 group ,there were significant rise in LVEF [ (48.98 ± 1.55)% ,(44.67 ± 1.48)% vs .(55.13 ± 4.27)% ,(53.73 ± 3.52)% ,(57.95 ± 2.89)% ] ,urine volume [ (1118.83 ± 168.09 ) ml , (1125.47 ± 177.28 ) ml vs . (1655.67 ± 198.37 ) ml , (1697.47 ± 171.27 ) ml , (1702.72 ± 179.28) ml] and Ccr level [ (40.11 ± 1.79) ,(41.11 ± 1.39) vs .(52.33 ± 2.49) ,(50.97 ± 2.11) , (51.32 ± 2.01 )] , and significant reduction in NT‐proBNP level [ (3738.19 ± 118.77 ) , (3378.38 ± 121.82 ) vs . (2137.51 ± 123.59) ,(2421.12 ± 121.22) ,(2139.81 ± 147.28)] in type 1 ,2 and 3 group ,P<0.05 all .Conclusion:CRRT is effective on different types of CRS ,but it′s best on type 1~3 than those of type 4~5 , which may be re‐lated to different pathological mechanisms of CRS different types .
