ABSTRACT
Objective To investigate mortality risk factors in patients with severe cardiorenal syndrome treated with continuous hemofiltration therapy. So we can optimally select patients who may benefit more from this therapy. Methods The clinical data of 68 severe cardiorenal syndrome patients admitted to the ICU of Beijing Shijitan Hospital from May 2012 to May 2015 were retrospectievly analyzed and evaluated. These patients were divided into two groups based on survival or death during hospitalization. Logistic regression analysis was employed to identify independent risk factors for death of patients with severe cardiorenal syndrome during ICU stay. Results There were 36 cases in the death group and 32 cases in the survival group. In the death group, the age,mechanical ventilation rates, vasoactive drug application rates, leukocytes, neutrophils, C-reactive protein,left ventricular end-diastolic diameter and left ventricular end-systolic diameter were significantly higher than those in the survival group,while hemoglobin, serum creatinine, left ventricular ejection fraction, average single amount of dehydration in continuous hemofiltration process were significantly lower than those in the survival group. Logistic regression analysis showed that age, vasoactive drug application rates, APACHEⅡscore and leukocytes were independent risk factors of mortality. Conclusions Cardiac function, mechanical ventilation therapy, average single amount of dehydration in continuous hemofiltration, hemoglobin, C-reactive protein were closely related to the prognosis of severe cardiorenal syndrome patients. The patient′s age,infection, vasoactive drug application, APACHEⅡ score were important risk factors of mortality during hospitalization.
