Figure 3 Plot between the measured left ventricular ejection fraction (LVEF) (X axis) and the difference between measured LVEF and the lower limit of the 95% confidence interval of the predicted LVEF for a given end systolic stress (ESS) (Y axis). (Left) Predicted LVEF was defined by the model obtained in controls (LVEF = 87.55 – 0.38 · ESS, r = 0.75, p < 0.0001). (Right) Predicted LVEF was defined by the model obtained in cyclists (LVEF = 80.34 – 0.29 · ESS, r = 0.71, p < 0.0001). Results are shown for the 17 cyclists with both left ventricular internal diameter at end diastole >60 mm and LVEF <52% (solid circles), the remaining cyclists (n = 269) (+), and the control group (n = 52) (open squares).
