“…Chronotropic incompetence, defined as a blunted increase in HR during exercise, relates to worse symptomatic status and diminished exercise capacity in a variety of clinical entities [ 49 ]. However, in patients with AS patients who are often elderly, with increased arterial stiffness [ 50 , 51 ], and relatively frequent use of β blockers [ 52 , 53 ], a blunted HR increase may have limited clinical and prognostic importance. The data on a blunted HR increase in AS patients is scarce and should be explored in future prospective studies.…”

Background: Routine exercise testing in asymptomatic patients with valvular heart disease (VHD) better classifies the hemodynamic severity of valve stenosis or regurgitation, and describes the symptomatic status and functional capacity of the patient. This is crucial for planned surveillance and optimal timing of surgery, particularly for aortic stenosis (AS), because once symptoms occur, there is a sharp increase in the risk of sudden death unless valve intervention is performed. Purpose: To conduct a focused clinical review on the benefits of exercise testing in patients with AS. Methods: The electronic database PubMed was systematically searched for relevant retrospective and prospective cohort studies reporting on the safety, feasibility and tolerability of exercise testing in VHD, with a special focus on AS. Results and conclusions: In patients with significant AS, exercise testing is safe, feasible and reveals symptoms in a significant proportion of patients. In addition, serial testing has incremental prognostic value over a baseline test alone. Exercise testing in patients with AS is underused and should be performed routinely to refine the hemodynamic severity of AS.
