A new study on Cardiology Journal investigates the role of the information obtained by Cardiopulmonary Exercise test in patients with limited aortic valve area (AVA).

The aim of this study was to determine the feasibility, reproducibility, safety and information obtained on exercise physiology from cardiopulmonary exercise testing (CPX) in patients with aortic stenosis.

Patients with an aortic valve area (AVA) inferior to 1.3cm2 who were judged asymptomatic or equivocal symptomatic underwent CPX and an inert gas rebreathing test. Only those where comprehensive evaluation of CPX results indicated haemodynamic compromise from aortic stenosis were referred for valve replacement.

The study findings confirm that "CPX was feasible and reproducible and provided comprehensive data on exercise physiology. A CPX-guided treatment strategy was safe up to 1 year."
