Primary Outcome Measures:
  • Change in VO2 submax and or VO2 max [ Time Frame: 7 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change in 6MWT [ Time Frame: 7 days ] [ Designated as safety issue: No ]
  • Change in WHO functional class [ Time Frame: 7 days ] [ Designated as safety issue: No ]
  • Change in echocardiographic parameters [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    Change in; pulmonary artery systolic pressure (PASP), ventricular diastolic function, systolic right and left ventricular function, right and left atrial/ventricular dimensions will be calculated

  • Change in exhaled NO [ Time Frame: 7 days ] [ Designated as safety issue: No ]
  • Change in systemic bloodpressure [ Time Frame: 7 days ] [ Designated as safety issue: No ]
  • Change in metabolic pathways involved in nitric oxide production and regulation [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    Change in the following biochemical variables will be calculated; ADMA, SDMA, Arginine, Citrulline, Ornithine, uric acid, nitrate, nitrite

  • Change in NT-pro-BNP [ Time Frame: 7 days ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: Nitrate rich beetroot juice
Eligible subjects will be randomised, in a double-blind crossover design, to receive treatment with either nitrate rich beetroot juice (70 ml containing approximately 4 mmol nitrate - active comparator)or nitrate depleted beetroot juice (70 ml - placebo) twice daily for 7 days (treatment period 1) followed by a 7 day washout period followed by treatment twice daily with the active comparator or placebo depending on initial treatment for another 7 days (treatment period 2) .
Dietary Supplement: Beetroot juice
Placebo Comparator: Nitrate depleted beetroot juice
Eligible subjects will be randomised, in a double-blind crossover design, to receive treatment with either nitrate rich beetroot juice (70 ml containing approximately 4 mmol nitrate - active comparator)or nitrate depleted beetroot juice (70 ml - placebo)twice daily for 7 days (treatment period 1) followed by a 7 day washout period followed by treatment twice daily with the active comparator or placebo depending on initial treatment for another 7 days (treatment period 2) .
Dietary Supplement: Beetroot juice
