Central hemodynamic patterns during recovery from peak exercise

We hypothesized that hemodynamic recovery patterns in exercise induced pulmonary hypertension (eiPH) and pulmonary venous hypertension (eiPVH) would differ. 442 consecutive invasive cardiopulmonary exercise tests at our center from 2012-2014 were reviewed. Recovery hemodynamics were available in 245. 36 eiPH, 28 eiPVH and 31 age matched normal controls (NC) were identified at peak exercise. eiPVH had significantly lower HRmax vs. NC (72±13 vs. 87±11% predicted, p eiPVH decays quickly in recovery while markers of eiPH including resistance and compliance persist. The data suggest more fixed pulmonary vascular remodeling in eiPH than in eiPVH.
