Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To test if infusion of the V1A/V2-receptor blocker conivaptan improves hemodynamics and physical capacity in HF patients on optimal HF medical therapy and to improve understanding of the role of vasopressin in HF.;Secondary Objective: Not applicable;Primary end point(s): -PCWP at the submaximal exercise intensity of 50 % of the maximal exercise capacity ;Timepoint(s) of evaluation of this end point: 1 day | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): -Cardiac index (CI) during submaximal exercise before and during conivaptan-infusion -Pulmonary and peripheral vascular resistance during exercise -Left ventricular end diastolic diameter during exercise -The Doppler-index of the left ventricular filling (E/e’) during exercise -The change in BNP, MR-ANP and copeptin from rest to submaximal exercise ;Timepoint(s) of evaluation of this end point: 1 day | — |
