Exercise intolerance is the clinical hallmark of the failing heart. Evidence of hemodynamic derangement is not always present at rest, often necessitating dynamic challenges to accentuate abnormalities. Although cardiac catheterization, particularly with exercise, remains the gold standard method for hemodynamic assessment, it is limited by practicality, access, risk, and its invasive nature; consequently, there is a need to better understand noninvasive measures. Echocardiography and cardiac MRI offer promising modalities to quantify ventriculo-vascular interactions. Significant heterogeneity exists around exercise protocols, and there is a need to develop consensus methodology and to valid..View full abstract
