Key result
Patients with pulmonary arterial hypertension had higher right ventricular kinetic energy work density and percent pulmonary artery energy loss compared to healthy subjects.
Why the study?
Does 4D flow MRI identify altered right ventricular kinetic energy work density and viscous energy dissipation in patients with pulmonary arterial hypertension compared to healthy subjects?
Observational (n=19)
No

Han et al. (2015) conducted an observational in Pulmonary Arterial Hypertension (n=19). 4D Flow MRI vs. Healthy subjects was evaluated on Right ventricular kinetic energy work density (p=0.007). Patients with pulmonary arterial hypertension had higher right ventricular kinetic energy work density and percent pulmonary artery energy loss compared to healthy subjects.
