The Threshold for a Clinically Meaningful Improvement in Cardiopulmonary Exercise Testing Measures for Patients With Symptomatic Obstructive Hypertrophic Cardiomyopathy
By pooling data from two phase 3 clinical trials, this study establishes that a change in peak oxygen uptake of +0.35 mL/kg/min represents the minimally important difference for patient-perceived clinical improvement in obstructive hypertrophic cardiomyopathy, providing a validated, patient-centered threshold to guide treatment decisions and future trial designs.
