Definition
Pulmonary hypertension (PHT) is defined by mean pulmonary artery pressure greater (mPAP) than 25 mmHg at rest,.Other hemodynamic characteristics include pulmonary capillary wedge pressure (PCWP),left atrial pressure or left ventricle end-diastolic pressure (LVEDP) less that 15 mmHg ,and pulmonary vascular resistance greater than 3 Wood units .
