Implication
Viability testing may identify revascularization beneficiaries in LV dysfunction; leaves open randomized confirmation of survival benefit.
Structured PICO
Does revascularization improve survival compared to medical treatment in patients with coronary disease and LV dysfunction with myocardial ischemia or viability?
P
Population
137 consecutive patients with coronary disease and left ventricular (LV) dysfunction who underwent exercise-redistribution-reinjection thallium scintigraphy and dobutamine echocardiography
I
Intervention
Revascularization (n=94)
C
Comparator
Medical treatment (n=43)
O
Outcome
Cardiac mortalityhard clinical
In patients with chronic LV ischemic dysfunction, the presence of ischemic or viable myocardium on noninvasive imaging predicts improved survival with revascularization.
