Association of Myocardial Ischemia With Mortality and Implantable Cardioverter-Defibrillator Therapy in Patients With Coronary Artery Disease at Risk of Arrhythmic Death

Ischemia during stress echocardiography is an independent predictor of death and ICD therapy in patients with coronary heart disease at high risk of arrhythmic death. Patients without inducible ischemia or VT on a previous EP study have a very low risk of events. A combination of ischemia and a positive EP study is associated with a very high risk of events.
