Abstract:Objective To explore the related risk factors for type I cardiorenal syndrome (CRS) among hospitalized patients with acute left heart failure. Methods A total of 176 cases who were hospitalized with the diagnosis of acute left heart failure in our hospital from May 2010 to May 2015 were chosen. Depending on the occurrence of type I CRS or not, the patients were divided into study group (type I CRS) and the control group (without type I CRS). The clinical and biochemical test results and the primary disease history of the two groups were retrospectively analyzed.The relating risk factors of type I CRS were analyzed in the patients. Results The incidence of type I CRS in the patients with acute left heart failure was 31.81% . Age, Hb, BNP, BUN, SCr, UA, MDRD -eGFR, dilated cardiomyopathy, hypertension, diabetes, and use of diuretics and vasoactive drugs were statistically different between the study group and the control group (P < 0.05). After adjusting other factors with logistic regression analysis,MDRD-eGFR <60 ml/min (OR = 3.795), anemia (OR = 8.542) and hypertension (OR = 5.02), diabetes (OR =2.65), use of diuretics (OR = 3.45) and vasoactive drugs (OR = 1.99) were the independent predictors of type I CRS in the patients with acute left heart failure. Conclusions Type I CRS is a common complication in patients hospitalized for acute left heart failure, and the prevalence is high. MDRD-eGFR <60 ml/min and anemia on admission are the independent risk factors of type I CRS. Hypertension, diabetes mellitus, and the use of diuretics and vasoactive drugs after admission may increase the incidence of type I CRS in patients with acute heart failure.
