The magnitude and course of exercise-induced stroke volume changes determine the exercise tolerance in heart transplant recipients with heart failure and normal ejection fraction

Original language description

Objectives: There is a large variability of exercise-induced stroke volume behavior in healthy subjects. We sought to assess the course of exercise-induced changes in stroke volume index (SVI) and other functional parameters in post-heart transplant patients with heart failure and normal left ventricular ejection fraction (HFNEF). Methods: Left ventricular function and systemic hemodynamics were assessed at 40 s intervals during the exercise in 39 patients using simultaneous right heart catheterization,bioimpedance, and echocardiography. Results: Twenty-six patients had exercise tolerance &gt;/= 4.0 METs (Group A), while 13 patients exhibited severely limited exercise tolerance &lt; 4 METs (Group B). Maximal SVI (maxSVI) achieved at any time during the exercise exceeded SVI at peak exercise (peakSVI) in 26 patients (67%). Both maxSVI and maxSVI (maxSVI minus SVI at rest) were significantly higher in Group A compared to Group B patients (59 ml/m2 vs 41 ml/m 2, p &lt; 0.
