Pulmonary Hypertension
Pulmonary hypertension (PH) comprises a group of diseases that cause elevated blood pressure in the pulmonary arteries. Pulmonary hypertension is diagnosed when the mean arterial pressure (mPAPA) is measured by right-sided heart catheterization and is found to be equal to or greater than 20 mmHg at rest.
It is caused by a variety of underlying conditions and is usually a manifestation of advanced disease. Approximately 1% of the global population and 50% of those with heart failure experience pulmonary hypertension.
Types of Pulmonary Hypertension
Pulmonary hypertension has been classified by WHO into five categories based on etiology.
- Pulmonary arterial hypertension (PAH)
- Pulmonary hypertension due to left-sided heart disease
- Pulmonary hypertension due to chronic lung disease and/or hypoxia
- Chronic thromboembolic pulmonary hypertension (CTEPH)
- Pulmonary hypertension due to unknown cause
