ABSTRACT
BACKGROUND:
The benefits of exercise training in patients with chronic heart failure (CHF) are due to a combination of cardiac and peripheral adaptations. Separating these 2 components is normally impossible, except for patients implanted with total artificial heart (TAH), where cardiac adaptation cannot occur. METHODS ANDRESULTS:
We report the case of a patient implanted with a CardioWest-TAH who underwent a comprehensive strength and endurance training program and was evaluated by repeated peak cardiopulmonary exercise tests. The patient experienced a 24% increase of peak oxygen consumption and an improvement in recovery kinetics during the training period of 29 months.CONCLUSION:
This unique situation of a patient with a TAH, and therefore a fixed peak cardiac output, allows us to isolate training-induced changes in the periphery, that suggest greater oxygen extraction and more efficient metabolic gas kinetics during the exercise and recovery phases.
