Outcome Measures

Primary Outcomes (1)

  • Maximal oxygen uptake (VO2max) measured in mL/kg/min

    VO2max is the maximal measured oxygen uptake during a symptom limited exercise test.

    10 weeks

Secondary Outcomes (5)

  • Mean pulmonary arterial pressure (mPAP) measured in mmHg

    10 weeks

  • Pulmonary vascular resistance (PVR) measured in dynes

    10 weeks

  • Right ventricular contractile function measured as % fractional area change (RV FAC).

    10 weeks

  • Left ventricular contractile function measured as % fractional area change (LV FAC).

    10 weeks

  • Slope of the relationship between mean pulmonary arterial pressure and cardiac output (mPAP-Q slope) measured in mmHg/L/min.

    10 weeks

Study Arms (2)

Exercise Training

EXPERIMENTAL

Two sets of exercise testing (before and after) 10 weeks of supervised exercise training (3 sessions per week) at Mayo Clinic Florida.

Other: Exercise Training

Control Groups

NO INTERVENTION

Two sets of exercise testing while continuing with standard medical care in between.

Interventions

10 weeks of supervised exercise training, 3 sessions per week at the cardiac rehab clinic at Mayo Clinic Florida.

Also known as: Cardiac Rehab
