Open AccessRight atrial and ventricular strain detects subclinical changes in right ventricular function in precapillary pulmonary hypertension
Right ventricular (RV) ejection fraction (EF) by cardiac magnetic resonance (CMR) correlates to outcome in precapillary pulmonary hypertension (pPH) patients, but is insensitive to early changes. Strain might ...

The effect of renal denervation on kidney oxygenation as determined by BOLD MRI in patients with hypertension
Renal denervation (RDN) is a promising therapy for resistant hypertension. RDN is assumed to decrease sympathetic activity. Consequently, RDN can potentially increase renal oxygenation. Blood oxygen level-depe...
