How Pulmonary Arterial Hypertension can be categorized?

Pulmonary hypertension is classified into five groups depending on its cause.

Group 1: Pulmonary Arterial Hypertension

  • Cause unknown, known as idiopathic pulmonary arterial hypertension
  • A specific gene mutation that can cause pulmonary hypertension to develop in families, also called heritable pulmonary arterial hypertension.
  • Certain drugs, such as diet drugs
  • Heart abnormalities present at birth, also called congenital heart disease
  • Other conditions, such as connective tissue disorders (HIV infection or chronic liver disease)

Group2: Pulmonary hypertension caused by left-sided heart disease

  • Left-sided valvular heart disease
  • Failure of the lower left heart chamber (left ventricle)

Group3: Pulmonary hypertension caused by lung disease

  • Chronic obstructive pulmonary disease, such as emphysema
  • Lung disease such as pulmonary fibrosis
  • Sleep apnea and other sleep disorders
  • Long-term exposure to high altitudes in people who may be at higher risk of pulmonary hypertension

Group4: Pulmonary hypertension caused by chronic blood clots

  • Chronic blood clots in the lungs (pulmonary emboli)

Group5: Pulmonary hypertension associated with other conditions that have unclear reasons why the pulmonary hypertension occurs

  • Blood disorders
  • Disorders that affect several organs in the body
  • Metabolic disorders
  • Tumors pressing against arteries
