In medicine, pulmonary hypertension is "increased vascular resistance in the pulmonary circulation, usually secondary to heart diseases or lung diseases."[1]
Diagnosis
The echocardiogram may be more than 10 mm/Hg in error in half of cases.[2]
Treatment
For all patients, consider:
- Inhibitors of phosphodiesterase type 5 (PDE-5), such as sildenafil.
For patients with New York Heart Association (NYHA) class IV symptoms inspite of calcium-channel antagonists, consider:
- Prostaglandins, such as iloprost, treprostinil, or epoprostenol.
- Endothelin receptor antagonists such as bosentan.
