Efficacy and Safety of Ultrafiltration in Patients with Heart Failure: A Single-Center Experience.

INTRODUCTION

There is a paucity of literature on the efficacy and safety of ultrafiltration in Chinese patients with heart failure (HF). Therefore, we aimed to compare the efficacy and safety of ultrafiltration with diuretics and provide information and evidence as to the best approach for patients with HF.

METHODS

In this single-center, non-randomized interventional study patients with HF either received diuretics or ultrafiltration. The efficacy outcomes included changes in the weight, dyspnea score, and 6-min walk distance from baseline to 48 h after treatment. Safety outcomes were evaluated in both the groups with respect to changes in systolic blood pressure, heart rate, serum creatinine, blood urea nitrogen, blood potassium ion concentration, and blood sodium ion concentration.

RESULTS

A total of 149 patients with HF (diuretics, 73; ultrafiltration, 76) were included. At 48 h, patients in the ultrafiltration group showed significantly greater weight loss and better improvement in dyspnea score and 6-min walk distance compared to patients in the control group (P < 0.05). However, the two groups showed no statistically significant difference in terms of safety outcomes such as systolic blood pressure, heart rate, serum creatinine, blood urea nitrogen, blood potassium ion concentration, and blood sodium ion concentration, suggesting similar safety profiles of both the groups.

CONCLUSION

Ultrafiltration was associated with greater weight loss and better dyspnea score and 6-min walk distance with similar safety profiles as compared with diuretics. Ultrafiltration can be considered as an optimal option for Chinese patients with HF.
