FIGURE 4. Exercise RVEF Correlates with Resting RV-PA Coupling and Predicts Early RV-PA Uncoupling.

FIGURE 4.

(A) Two-way scatter plot and correlation of Exercise RVEF and resting Ees/Ea (r=0.63, P<0.001). (B) Full cohort split into tertiles of exercise RVEF; Ees/Ea (mean±SEM) shown for each tertile. Only the highest (i.e., third) tertile of exercise RVEF had a preserved Ees/Ea; even a small decline in exercise RVEF signifies worsening resting Ees/Ea. (C) Exercise RVEF showed excellent ability for predicting occult RV dysfunction (Ees/Ea<1.0) with AUC=0.81. Exercise RVEF <38% had optimal sensitivity (85%) and specificity (77%).
