简要总结
Gliflozins have demonstrated a beneficial effect in terms of incident heart failure and related events in patients with or without diabetes. The clinical trial ICARD is an exploratory study that aims to evaluate the cardiometabolic mechanistic effects on the myocardium of dapagliflozin in heart failure with reduced ejection fraction. Deep phenotyping of cardiac and vascular function will be performed using MRI. Myocardial tissue characterization will be based on MRI and FDG-PET for glucose metabolism assessment. Liver steatosis and fibrosis will simultaneously be assessed.
详细描述
Open-label, non-controlled clinical trial (Jardé 1) to assess the cardiovascular and metabolic effects of once-daily dapagliflozin 10 mg during 6 months in patients with heart failure and reduced ejection fraction.
Eligibility of patients addressed to the Department of Cardiology (Prof R. Isnard, Pitié-Salpêtrière Hospital, Paris, France) will be investigated at V0: inclusion and exclusion criteria will be checked and informed consent will be signed.
Up to twenty one days after V0, patients will come to the VMRI visit (VMRI) for the cardiac and liver gadolinium-injected MRI and AGE Reader (VRMI) and to the baseline visit (V1). Pregnancy will be ruled out in women of childbearing potential with blood beta-HCG. A blood test (including metabolomics and lipidomics) and FDG-PET MRI including Glucose Tolerance Test (GTT) will be performed. Dapagliflozin 10 mg once daily during six months will be prescribed.
Fifteen to twenty-one days after treatment initiation, a safety visit (V2) will take place in order to verify the tolerance.
A pre-final visit (V3) will be organized after a total of 23 weeks (± 1 week) of treatment. Pregnancy will be ruled out in women of childbearing potential with blood beta-HCG. A blood test (including metabolomics and lipidomics), ECG, trans-thoracic echocardiography (TTE), cardiac and liver MRI and AGE Reader will be performed.
