Reduced Left Ventricular Ejection Fraction in Patients With Aortic Stenosis.
Journal of the American College of Cardiology（2018）
Abstract
In patients with severe AS and reduced LVEF, a decline in LVEF began before AS became severe and accelerated after AVA reached 1.2 cm. LVEF <60% in the presence of moderate AS predicts further deterioration of LVEF and appears to represent abnormal LVEF in AS.
