Primary Outcome Measures :
  1. Peak change from baseline of PCWP (pulmonary capillary wedge pressure) [ Time Frame: baseline, after 8 and 20 hrs treatment ]
    Measurements will be made using a Swan-Ganz indwelling catheter

  2. Peak change from baseline of CI (cardiac index) [ Time Frame: baseline, after 8 and 20 hrs treatment ]
    Measurements will be made using a Swan-Ganz indwelling catheter


Secondary Outcome Measures :
  1. Change over time of PCWP (pulmonary capillary wedge pressure) [ Time Frame: During 20 hours of infusion and up to 4 hours after stop of infusion ]
    Measurements will be made using a Swan-Ganz indwelling catheter

  2. Change over time of systemic vascular resistance (SVR) [ Time Frame: During 20 hours of infusion and up to 4 hours after stop of infusion ]
    Measurements will be made using a Swan-Ganz indwelling catheter

  3. Change over time of pulmonary vascular resistance (PVR) [ Time Frame: During 20 hours of infusion and up to 4 hours after stop of infusion ]
    Measurements will be made using a Swan-Ganz indwelling catheter

  4. Change over time of pulmonary arterial pressure (PAP) [ Time Frame: During 20 hours of infusion and up to 4 hours after stop of infusion ]
    Hemodynamic measurements were made using a Swan-Ganz catheter when patients were in a supine position

  5. Change over time of pulmonary and peripheral oxygen saturation [ Time Frame: During 20 hours of infusion and up to 4 hours after stop of infusion ]
    Hemodynamic measurements were made using a Swan-Ganz catheter when patients were in a supine position

  6. Pharmacokinetics of RLX030: area under the serum concentration-time curve from time zero to infinity (AUCinf) [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    Blood will be collected from an in dwelling catheter.

  7. Pharmacokinetics of RLX030: area under the serum concentration-time curve from time zero to the time of the last quantifiable concentration (AUClast) [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    Blood will be collected from an in dwelling catheter.

  8. Pharmacokinetics of RLX030: serum concentration over 20 hours of infusion (C20h) [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    Blood will be collected from an in dwelling catheter.

  9. Pharmacokinetics of RLX030: terminal elimination half-life (T1/2) [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    Blood will be collected from an in dwelling catheter.

  10. Pharmacokinetics of RLX030: mean residence time (MRT) [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    Blood will be collected from an in dwelling catheter.

  11. Pharmacokinetics of RLX030: volume of distribution at steady state following intravenous administration [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    Blood will be collected from an in dwelling catheter.

  12. Change over time on calculated creatinine clearance [ Time Frame: During 20 hours of infusion and 4 hours after stop of infusion ]
    Urine samples will be collected for analyses.

  13. Change over time in Diuresis [ Time Frame: During 20 hours of infusion and 4 hours after stop of infusion ]
    Urine samples will be collected for analyses.

  14. Central aortic systolic pressure-time curve [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    A cuff will be used for a brachial blood pressure measurement and a wrist sensor for arterial pulse waveforms

  15. Radial augmentation index-time curve [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    A cuff will be used for a brachial blood pressure measurement and a wrist sensor for arterial pulse waveforms

  16. Number of patients with adverse events, serious adverse events and death [ Time Frame: During 20 hours of infusion and 24 hours after stop of infusion ]
    Adverse events will be assessed by signs/symptoms, clinical laboratory and electrocardiographs.
