Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint will be the difference in volume of perirenal adipose tissue measured on abdominal CT in patients with HFpEF vs. healthy age, sex and BMI matched controls. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints will include the following: • The difference in renal (arterial and venous) blood flow as assessed with DCE-CT between HFpEF patients vs. healthy age, sex and BMI matched controls • The difference in renal venous flow pattern assessed with renal ultrasound between HFpEF patients vs. healthy age, sex and BMI matched controls • Estimated glomerular filtration rate assessed with DCE-CT. • Concentration of urine KIM-1 and OPN, serum creatinine and plasma cystatin C. • Correlation of NT pro BNP, plasma renin and plasma aldosterone concentration to perirenal adipose tissue diameter in patients with HFpEF, as well as to pulmonary arterial pressure as assessed with cardiac ultrasound • Differences between men and women with HFpEF for all aforementioned endpoints. Exploratory endpoint will include the following: • Correlation of clinical signs and symptoms of congestion to renal ultrasound flow patterns and to degree of renal damage as assessed with tubular markers • Pancreatic and hepatic aspects and size in patients with HFpEF based on late venous abdominal CT scan. | — |
