Figure 3 Dobutamine stress echocardiography (DSE) in ischemic left ventricular (LV) dysfunction impact on survival. Mortality rates at a mean follow-up of 18 ± 10 months in patients with chronic LV dysfunction, grouped by the presence of viability by DSE and by whether or not patients underwent revascularization (+Rev and –Rev, respectively). *p = 0.01 vs. others.
