Follow-up strategies for patients with dyspnea or after an acute disease (as pulmonary embolism [PE]) remained challenging due to its complexity of multiple diagnostic modalities including imaging, laboratory and cardio-pulmonary exercise testing. Regarding imaging testing in patients with post-PE cardiac impairment, which is characterised by incomplete RV echocardiographic recovery, as indicated by an intermediate or high echocardiographic probability of pulmonary hypertension (according to the ESC criteria, this requires the assessment of peak tricuspid regurgitation velocity and/or RV dilatation and hypokinesia plus the presence of exertional dyspnea), new non-invasive approaches would be appreciated as proposed by L. Gargani et al. This exercise approach based on echocardiography could serve as a new diagnostic testing tool regarding post-PE care.
