Cine magnetic resonance imaging detects shorter cardiac rest periods in postcapillary pulmonary hypertension
Authors' conclusion
Postcapillary PH is independently associated with shorter cardiac rest periods at mid-to-late diastole.
Study context
- Population
- Patients with postcapillary pulmonary hypertension and healthy controls, heart rate ≤80 beats/minute, undergoing cardiac magnetic resonance imaging (MRI)
- Participants
- 26 vs 20
- Exposure
- Postcapillary pulmonary hypertension (PH) vs healthy controls
- PHn = 26
- Controlsn = 20reference
- Outcome
- Length of cardiac rest periods at end-systole and mid-to-late diastole on cine MRI (four-chamber view)
Main finding
As reported in the abstract
Rest period at mid-to-late diastole
P = 0.003
Observational data: associations, not effects.

Discrimination of PH from controls by proportion of rest period in diastole (diastasis/diastole), ROC
- AUC
- 0.83 (95% CI 0.71-0.96)
