Key result
Stress echocardiography unmasks symptoms in apparently asymptomatic severe AS to help guide AVR timing.
Why the study?
Elderly patients with aortic stenosis may underreport symptoms, have comorbidities, or subconsciously limit activity, making stress testing potentially vital to uncover symptoms and prognosticate.
Does stress echocardiography improve risk stratification and clinical decision-making in patients with asymptomatic severe aortic stenosis?
Does stress echocardiography improve risk stratification and clinical decision-making in patients with asymptomatic severe aortic stenosis?
Stress echocardiography is a valuable objective tool for unmasking symptoms and risk-stratifying patients with apparently asymptomatic severe aortic stenosis to guide timely intervention.
May support refined risk stratification in asymptomatic severe aortic stenosis; leaves open confirmation via randomized outcome trials.
Aortic stenosis (AS) is one of the most common adult valve diseases. Therefore, current guidelines recommend prompt aortic valve intervention once symptoms occur. However, AS is predominantly a disease of the elderly, and these people may be underreporting their symptoms, have other comorbidities, or have a low level of exertion at the baseline or they might make a subconscious adjustment of their activities. Hence, stress testing can be a vital and objective tool to uncover their symptoms and prognosticate.

Abusweireh et al. (2022) conducted a review in Asymptomatic severe aortic stenosis. Stress echocardiography was evaluated. Stress echocardiography unmasks symptoms and provides prognostic information in patients with apparently asymptomatic severe aortic stenosis, helping to guide the timing of aortic valve replacement.
