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

In the DAPA-HF trial, the use of dapagliflozin, an inhibitor of sodium-glucose cotransporter 2 (SGLT2), reduced significantly the risk of worsening heart failure or death from cardiovascular causes compared to placebo among patients with heart failure (HF) and a reduced ejection fraction. This new drug offers a very potent and interesting therapeutic pathway since it reduces clinical congestion, it preserves glomerular renal function, does not appear to cause symptomatic clinical hypotension and improves symptoms and quality of life compared to placebo. Advanced heart failure patients with reduced ejection fraction represent a small and severe subgroup of heart failure of patients with frequent worsening heart failure events and high rates of death. The effect of dapagliflozin in this subgroup of patients was not assessed in the DAPA-HF study. The therapeutic profile of SGLT2 inhibitors appears to be of high interest, since this group of patients has a poor tolerance to usual heart failure drugs, frequent worsening renal function and congestive symptoms persistence with poor quality of life scores. Soluble urokinase-type plasminogen activator receptor (suPAR) is a signaling glycoprotein considered to be involved in the pathogenesis of kidney disease. It is associated with the risk of acute kidney injury in different clinical and experimental situation. It is also a new validated biomarker predictive of adverse clinical outcome in heart failure patients. This biomarker allows a better risk stratification in heart failure patients after adjustment for Nt-proBNP. As a useful biomarker implicated in both heart failure and acute kidney injury, suPAR seems to be an interesting biomarker to assess cardio-renal benefits of dapagliflozin. The aim of this study is to investigate if a treatment by dapagliflozin reduces significantly suPAR compared to placebo in a population of advanced heart failure patients, candidates to heart transplantation. The effect of dapagliflozin compared to placebo will also be assessed on other secondary heart failure outcomes in this patient population.
