Implication
Exercise parameters may predict events in asymptomatic severe AS; leaves open whether they should guide early surgery.
Structured PICO
Does exercise echocardiography predict adverse cardiac events and identify candidates for early surgery in asymptomatic patients with severe aortic stenosis and preserved left ventricular ejection fraction?
P
Population
Asymptomatic patients with severe aortic stenosis and preserved left ventricular ejection fraction
I
Intervention
Exercise echocardiography
O
Outcome
Prediction of adverse cardiac events and identification of patients who may benefit from early surgery
Exercise echocardiography is a safe, low-cost tool that provides incremental prognostic value to identify asymptomatic patients with severe aortic stenosis who may benefit from early valve replacement.
