Determinants of Exercise Capacity and Myocardial Perfusion Reserve in Asymptomatic Patients With Aortic Stenosis

Poor exercise capacity is associated with an adverse outcome in aortic stenosis (AS) and a positive exercise test is a class I indication for aortic valve replacement in asymptomatic AS [(1,2)][1]. The mechanisms leading to reduced exercise capacity and symptom onset are likely similar. Reduced
