Exercise stress echocardiography in patients with aortic stenosis: impact of baseline diastolic dysfunction and functional capacity on mortality and aortic valve replacement

摘要

BackgroundPatients with aortic stenosis (AS) often undergo exercise echocardiography. Diastolic dysfunction (DD) is frequently associated with AS but little is known about its impact on functional capacity (FC). We sought to determine the relationship between DD and FC and their impact on mortality and need for aortic valve replacement (AVR) in patients with AS.
