Primary outcome [1] 259749 0
The primary outcome will be the between group distribution of treatment success, treatment failure or no change in the patient?s clinical condition at Day 5. Treatment success = improvement in symptoms at D5. Treatment failure = death, readmission, worsening symptoms or signs of HF at D5, worsening renal function (= >27umol/L rise in creatinine).

Day 5 after hospital admission
Primary outcome [2] 269261 0
The co-primary end-point is an improvement in forearm blood flow (measured by venous occlusion plethysmography and endoPAT).
