Primary Pulmonary Hypertension: Pressures
built 640 days ago
Pulmonary hypertension is a complex problem characterized by nonspecific signs and symptoms and having multiple potential causes. It may be defined as a pulmonary artery systolic pressure greater than 30 mm Hg or a pulmonary artery mean pressure greater than 20 mm Hg.

No one knows what causes primary pulmonary hypertension. It may ... be referred to as idiopathic pulmonary hypertension. There are causes of elevated pressures in the lungs that are secondary or a result of some other process.

A physical examination is performed to look for typical signs of pulmonary hypertension. These include altered heart sounds, such as a widely split S2 or second heart sound, a loud P2 or pulmonic valve closure sound (part of the second heart sound), (para)sternal heave, possible S3 or third heart sound, and pulmonary regurgitation. Other signs include an elevated jugular venous pressure, peripheral edema (swelling of the ankles and feet), ascites (abdominal swelling due to the accumulation of fluid), hepatojugular reflux, and clubbing.
