Effect of the Use of Dapagliflozin in Patients With Refractory Heart Failure
- Registration Number
- NCT06578520
- Brief Summary
Cross-over, 2-sequence, 2-treatment, 2-period single-centre, phase IV, randomized, open label study.
- Detailed Description
Peritoneal dialysis (PD) is a technique that has been successfully used for the treatment of refractory heart failure to diuretics. In patients on PD, the harmful effects of sodium retention become even greater, resulting in fluid overload, hypertension and left ventricular hypertrophy in more than half of the PD population. This is due to the fact that the ...

- Primary Outcome Measures
Name Time Method Mean difference of the sum between 24-h natriuresis and the daily sodium elimination in the peritoneal effluent (mEq/L) in the 3rd (8th week) visit control compared with the 6th (20th week)visit control. Through study completion, an average of 4 months To explore the effect of iSGLT2 in natriuresis and the peritoneal elimination of sodium in patients with CKD and refractory HF treated with peritoneal dialysis.
- Secondary Outcome Measures
