Acute PE increases pulmonary vascular resistance, partly attributable to hypoxic vasoconstriction. In patients without prior cardiopulmonary disease, the mean pulmonary artery pressure can double to approximately 40 mm Hg. An additional doubling of pulmonary artery pressure may occur in patients with prior pulmonary hypertension. Under extreme circumstances in patients with chronic thromboembolic pulmonary hypertension, the pulmonary arterial pressure can exceed the systemic arterial pressure. http://circ.ahajournals.org/cgi/cont...8/22/2726#SEC1 |
