Elevated pulmonary artery pressure Post-capillary pulmonary hypertension 2021-02-01T13:21:16Z Post-capillary hypertension resulting from left heart disease causes backpressure and increases the hydrostatic pressure in the pulmonary veins which eventually results in increased pressure in pulmonary arteries. Post-capillary pulmonary hypertension is a hemodynamic condition characterized by elevated mean pulmonary artery pressure (mPAP greater than 20 mmHg) and pulmonary artery wedge pressure (PAWP greater than 15 mmHg) and pulmonary vascular resistance (PVR less than 3 Wood units).
