Acute Reno-Cardiac Action of Dapagliflozin In Advanced Heart Failure Patients on Heart Transplant Waiting List

Sponsor: Central Hospital, Nancy, France

Summary

Heart failure affects 1 to 2% of the adult population in developed countries, representing about 55 million people worldwide. Advanced heart failure is a condition where the heart can no longer provide sufficient cardiac output or equilibrate pressures within its chambers, leading to symptoms such as shortness of breath, fatigue, and water and salt retention. Heart failure affects the kidneys by reducing blood flow directed to them, sometimes leading to kidney congestion. In the long term, this can degrade kidney function. Common medications used to treat heart failure, such as diuretics, can sometimes worsen kidney failure. This link between the heart and the kidneys is known as cardio-renal syndrome and requires careful management of both organs to prevent mutual degradation. Dapagliflozin is an SGLT2 inhibitor medication used to treat type 2 diabetes, heart failure, and certain kidney diseases. It helps reduce blood sugar, improve heart and kidney function, while promoting the elimination of excess salt and water. However, there are limited data regarding the progression of cardio-renal interactions in patients with advanced heart failure. Yet, advanced heart failure is often associated with kidney dysfunction. The protein called suPAR is found in the blood of patients developing kidney disease and/or during the onset of acute kidney injury. This protein will allow to characterize a population of patients with advanced heart failure receiving optimized medical treatment, including dapagliflozin. The main objective of this research is to assess, based on the suPAR protein level in the blood, the progression of cardio-renal damage between inclusion and 6 months in patients with advanced heart failure who are listed for a heart transplant and treated with a therapy including dapagliflozin. The study plans 5 visits over 12 months. The research will take place in the cardiology department of several French hospitals.
