Relation of Ejection Fraction and Inducible Ventricular Tachycardia to Mode of Death in Patients With Coronary Artery Disease
Why the study?
Does ejection fraction or inducible ventricular tachyarrhythmia predict the mode of death in patients with coronary artery disease?

Implication
Inducible tachyarrhythmia may aid arrhythmic risk stratification in CAD beyond EF; hypothesis-generating from Level 3 data and should not change practice.
Structured PICO
Does ejection fraction or inducible ventricular tachyarrhythmia predict the mode of death in patients with coronary artery disease?
P
Population
1,791 patients with coronary artery disease enrolled in the Multicenter Unsustained Tachycardia Trial who did not receive antiarrhythmic therapy
O
Outcome
Mode of death (arrhythmic vs non-arrhythmic) and total mortalityhard clinical
Inducible ventricular tachyarrhythmia, but not ejection fraction, identifies patients with coronary disease whose death is more likely to be arrhythmic, particularly when EF is ≥30%.
