Here are the major types:
| Type | Main Cause | Key Aspects |
| Pulmonary Arterial Hypertension (PAH) | Narrowed lung arteries | Often idiopathic or connective tissue-related |
| Left Heart Disease–Related | Heart failure or valve disease | Back pressure into the lungs |
| Lung Disease–Related | COPD, ILD, sleep apnea | Low oxygen–induced vasoconstriction |
| Chronic Thromboembolic Pulmonary Hypertension (CTEPH) | Chronic blood clots | Scarred, blocked lung arteries |
| Unclear or Multifactorial | Mixed systemic causes | Multiple or unknown mechanisms |
The best Cardiologist in Ludhiana says the following factors can be the reasons behind lung blood vessel diseases:
Blood clots forming in deep leg veins (deep vein thrombosis) travel to the lungs. This can lead to blood flow blockage to the lungs.
Cardiac conditions like left-sided heart failure, mitral valve issues (a problem with the valve located between the left heart chambers), or congenital heart defects (like Tetralogy of Fallot) can cause back pressure into the lungs.
Conditions such as COPD (Chronic Obstructive Pulmonary Disease), emphysema (alveoli become abnormally inflated, making it harder to breathe), and lung fibrosis reduce oxygen. This causes lung arteries to constrict and thicken (hypoxic vasoconstriction), which strains the vessels and raises pressure in the lungs.
Autoimmune diseases such as lupus, scleroderma, and rheumatoid arthritis result in narrowed vessels, inflammation, scarring, and clotting. This disturbs the routine blood flow and oxygen exchange in the lungs.
Some appetite suppressants (Fen-Phen), amphetamines, and toxins interfere with serotonin pathways (triggering vessel narrowing). This induces abnormal growth and thickening of the lung’s artery walls, raising pressure.
The repeated breathing pauses during sleep decrease oxygen levels and raise carbon dioxide. This forces lung blood vessels to tighten and eventually thicken over time, causing pulmonary hypertension (abnormally high blood pressure in the arteries leading from the heart to the lungs).
Severe lung infections can cause inflammation and accumulation of fluid, which can trigger pulmonary circulation disorders.
