Pulmonary Hypertension

Show Summary Details

Preview

The normal pulmonary circulation has low-pressure, low-resistance flow through compliant, thin-walled vessels. Pulmonary hypertension is defined as a mean pulmonary arterial pressure greater than 25 mm Hg at rest. Clinically significant pulmonary hypertension is usually associated with substantially higher pulmonary artery pressures. Although a suspicion of pulmonary hypertension can be based on echocardiographic estimates, the diagnosis cannot be established without right heart catheterization. This chapter covers the diagnosis, assessment, and approach to treatment for patients with pulmonary hypertension.
