Figure 1 Overall Survival Curves
(A) Overall survival curves for patients with versus without ischemia and (B) with normal versus abnormal exercise echocardiography. Ischemia was defined as the development of new or worsening wall motion abnormalities with exercise, whereas an abnormal exercise echocardiography (EE) was defined as the presence of wall motion abnormalities at rest or the development of ischemia during exercise.

Figure 2 Survival Free of Major Adverse Cardiac Events
(A) Survival free of major adverse cardiac events (MACE) curves in patients with versus without ischemia and (B) with normal versus abnormal exercise echocardiography (EE). Ischemia was defined as the development of new or worsening wall motion abnormalities with exercise, whereas an abnormal EE was defined as the presence of wall motion abnormalities at rest or the development of ischemia during exercise.
