Left: individual rest and peak exercise ejection fraction values for patients with good exercise responses (group I) (solid lines) and poor exercise responses (group II) (dashed lines); in group I mean ejection fraction increased from 55% to 58% (solid squares), and in group II it decreased from 54% to 42% (solid circles). Middle: Distributions of individual values of systolic excursion and peak systolic velocity (right) of medial mitral annular motion, in patients with good exercise response (group I) and poor exercise response (group II). The dotted lines represent the best discriminant cut off values obtained in the analyses of sensitivity and specificity.
