Abstract
Background Pulmonary hypertension (PH) is a severe disorder defined as a mean pulmonary artery pressure (mPAP) ≥ 25mmHg at right heart catheterization. Previous research indicates the mPAP of healthy volunteers is 14mmHg (±3.3mmHg) at rest, and patients with mPAP of 21 to 24mmHg are considered as borderline PH. This study investigates demographic, co-morbidities, invasive haemodynamics and cardiac magnetic resonance (CMR) imaging characteristics of patients with borderline PH.
Highlights
Pulmonary hypertension (PH) is a severe disorder defined as a mean pulmonary artery pressure ≥ 25mmHg at right heart catheterization
This study investigates demographic, co-morbidities, invasive haemodynamics and cardiac magnetic resonance (CMR) imaging characteristics of patients with borderline PH
Patients with borderline PH have higher indexed RV end-diastolic volume and greater septal deviation but preserved RV functional metrics when compared to patients with normal pulmonary artery pressure
Summary
Pulmonary hypertension (PH) is a severe disorder defined as a mean pulmonary artery pressure (mPAP) ≥ 25mmHg at right heart catheterization. This study investigates demographic, co-morbidities, invasive haemodynamics and cardiac magnetic resonance (CMR) imaging characteristics of patients with borderline PH
