简要总结
The long-term objective of this study is to test whether the addition of SGLT2 inhibitors to usual care during acute heart failure management in patients who develop kidney injury shortens the time to achieving symptomatic improvement and kidney function recovery. The study aims to assess feasibility and acceptability of such a randomized clinical trial.
详细描述
Acute heart failure is associated with a significant risk of acute kidney injury which is present in up to a third of patients at the time of hospitalization. As adequate kidney function is necessary for self-decongestion, kidney injury makes the treatment of acute heart failure particularly challenging. SGLT2i are drugs consistently shown to reduce hospitalizations in heart failure as well as progression of kidney disease but are frequently discontinued during acute kidney injury. Although they have been included in the armamentarium of heart failure care as guideline directed medical therapy, a concern about the efficacy and safety in patients with kidney dysfunction remains a limitation to their widespread uptake particularly during heart failure exacerbation.
This study aims to enroll adults hospitalized with acute congestive cardiorenal syndrome and develop acute kidney injury in a randomized clinical trial of SGLT2i versus usual care to compare markers of decongestion and biomarkers of kidney injury and health to inform a larger randomized clinical trial. The overall aim is to assess if SGLT2i improve diuretic efficiency in patients with heart failure associated kidney injury. The long-term goal of this study is to promote increased use of SGLT2i by demonstrating their safety and possible benefit in patients who develop heart failure associated kidney injury to avoid interruptions in this setting.
The primary objective of this is study is to test the feasibility and acceptability of randomizing adults hospitalized with acute heart failure complicated by acute kidney injury to SGLT2i or usual care.
The secondary objectives of this study are:
- To compare changes in biomarkers of kidney injury, repair and tubular function in order to test whether the SGLT2 inhibitor (dapagliflozin) improves response to standard treatment
- To compare markers of decongestion (weight, urine volume, symptom score, diuretic de-escalation) to test whether the addition of SGLT2i to standard of care improves heart failure symptoms faster.
- To compare possible adverse events such as: sodium or potassium derangements, metabolic acidosis, urinary tract infections (UTI) or genital mycotic infections in those exposed to the SGLT2i dapagliflozin vs usual care.
- To compare hospital length of stay, mortality, progression to a higher stage of AKI, and persistent AKI at discharge

结局指标
主要结局
Enrollment rate
时间窗: From study initiation to study close (about 2 years)
Total enrollment into the study over study duration, to serve as a measure of feasibility.
Percentage of eligible versus consented patients
时间窗: From study initiation to study close (about 2 years)
Number of patients deemed eligible after assessment of inclusion and exclusion criteria and number of patients who consent, which serves as a measure of feasibility of enrolling patients with acute cardiorenal syndrome in a randomized clinical trial of SGLT2i.
Percentage of enrolled patients with completed sample collections
时间窗: From study initiation to study close (about 2 years)
Percentage of enrolled patients who have provided at least two days of urine samples and percentage of enrolled patients who have provided at least two days of blood samples, which serves as a measure of feasibility of enrolling and retaining patients with acute cardiorenal syndrome in a randomized clinical trial of SGLT2i.
