Figure 5 Relationship Between Cardiac Events and LVEF

Hazard ratio of experiencing a hard event (A) or any event (B) as a function of left ventricular ejection fraction (EF). Each point represents an event experienced by a study participant. The hazard values are relative to a patient without a dobutamine-induced increase in wall motion score index (WMSI) and a resting left ventricular EF = 40%.
