Pulmonary hypertension

Show Summary Details

Preview

Pulmonary hypertension (PH) is definedhaemodynamically as anincrease in mean pulmonary arterial pressure (mPAP) of at least25 mmHg at rest, as assessed by right heart catheterization (RHC).At the 2008 World Symposium on Pulmonary Hypertension inDana Point, mPAP of 20–25 mmHg was considered abnormal, andthe term ‘pre-PH’ was proposed to signify this. Previously, the definition of PH included exercise-induced PH (mPAP ≥ 30 mmHgon exercise). However, the data for exercise-induced PH is limited, and the recent reclassification of PH does not include exercise-inducedPH in its definition.
