Overview

Pulmonary hypertension can be classified into primary pulmonary hypertension (of unknown cause) which is currently known as idiopathic pulmonary arterial hypertension (IPAH) and secondary pulmonary hypertension due to another medical condition. The most common cause of pulmonary hypertension is left heart failure. Other common causes include HIV, systemic sclerosis, portal hypertension, congenital heart disease and sickle cell disease.[1]

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. Pulmonary hypertension in itself is not a life threatening condition, but it is progressively fatal if left untreated. Pulmonary embolism and acute left heart failure are two causes of pulmonary hypertension that can be quickly fatal.

Common Causes

The most common cause of pulmonary hypertension is left heart failure leading to pulmonary venous hypertension. Other Common causes of pulmonary arterial hypertension (PAH) include:

Idiopathic Pulmonary Arterial Hypertension

When none of the causes on this page can be found, the disease is termed idiopathic pulmonary arterial hypertension (IPAH).

Causes in Alphabetical Order


Causes by Clinical Classification

Class 1: Pulmonary arterial hypertension

  1. Idiopathic pulmonary arterial hypertension
  2. Heritable (BMPR2, ALK-1, ENG, SMAD9, CAV1, KCNK3)
  3. Drug and toxin induced

Class 2: Pulmonary hypertension due to left heart disease

  1. Left ventricular systolic dysfunction
  2. Left ventricular diastolic dysfunction

  4. Congenital/acquired left heart inflow/outflow tract obstruction and congenital cardiomyopathies

Class 3: Pulmonary hypertension due to lung diseases and/or hypoxia

  1. Chronic obstructive pulmonary disease
  2. Interstitial lung disease
  3. Other pulmonary diseases with mixed restrictive and obstructive pattern
  4. Sleep-disordered breathing
