Compression Therapy of the Lower Limbs in Patients With Decompensated Heart Failure

This study is testing whether applying compression therapy to the lower legs (like medical compression bandages or stockings) can help the body remove excess fluid more effectively in patients hospitalized with a sudden worsening of heart failure (acute decompensated heart failure) who have significant leg swelling. **You may be eligible if...** - You are 18 or older - You are being treated in hospital for acute (sudden, severe) worsening of heart failure, within the first 96 hours of starting IV diuretic (fluid-removing) treatment - You are receiving at least 40 mg of furosemide (a strong diuretic) in the past 24 hours - Your blood marker for heart stress (NT-proBNP) has been above 1000 pg/ml - You have significant lower leg swelling (at least grade II out of IV) - Your inferior vena cava (a large vein in the abdomen) measures 21 mm or less on ultrasound **You may NOT be eligible if...** - You are in an intensive care unit - You have had a kidney transplant, have severe chronic kidney failure, or are on dialysis - You have no pulse in your lower legs (absent peripheral pulses) - You have an ankle-brachial index below 0.9 (a sign of blocked blood flow to the legs) - You have severe peripheral artery disease - You have previously not tolerated compression bandaging - Your heart failure was caused by a recent heart attack Talk to your doctor to see if this trial is right for you.
