Fig 4. Comparing viscous energy loss in healthy subjects and patients with pulmonary arterial hypertension.

Fig 4

(A) The amount of viscous energy loss is higher in patients throughout the cardiac cycle. (B) The percent viscous energy loss is significantly greater in PAH patients than in healthy subjects (21.1±6.4% vs. 2.2±1.3%, p = 0.0001).
