What is the pathophysiology of pulmonary hypertension?

Pathophysiology of Pulmonary Hypertension Pulmonary hypertension is characterized by variable and sometimes pathologic vasoconstriction and by endothelial and smooth muscle proliferation, hypertrophy, and chronic inflammation, resulting in vascular wall remodeling.

What is the pathophysiology of pulmonary hypertension?

Pathophysiology of Pulmonary Hypertension Pulmonary hypertension is characterized by variable and sometimes pathologic vasoconstriction and by endothelial and smooth muscle proliferation, hypertrophy, and chronic inflammation, resulting in vascular wall remodeling.

What is the difference between pulmonary hypertension and arterial hypertension?

PAH: What’s the Difference? Pulmonary hypertension (PH) is a general term used to describe high blood pressure in the lungs from any cause. Pulmonary arterial hypertension (PAH) is a chronic and currently incurable disease that causes the walls of the arteries of the lungs to tighten and stiffen.

What causes pulmonary arterial hypertension?

Some common underlying causes of pulmonary hypertension include high blood pressure in the lungs’ arteries due to some types of congenital heart disease, connective tissue disease, coronary artery disease, high blood pressure, liver disease (cirrhosis), blood clots to the lungs, and chronic lung diseases like emphysema …

What are the 5 types of pulmonary hypertension?

The Five Groups

  • Group 1: Pulmonary Arterial Hypertension (PAH)
  • Group 2: Pulmonary Hypertension Due to Left Heart Disease.
  • Group 3: Pulmonary Hypertension Due to Lung Disease.
  • Group 4: Pulmonary Hypertension Due to Chronic Blood Clots in the Lungs.
  • Group 5: Pulmonary Hypertension Due to Unknown Causes.

What happens to pulmonary artery in pulmonary hypertension?

In one form of pulmonary hypertension, called pulmonary arterial hypertension (PAH), blood vessels in the lungs are narrowed, blocked or destroyed. The damage slows blood flow through the lungs, and blood pressure in the lung arteries rises. The heart must work harder to pump blood through the lungs.

How is pulmonary arterial hypertension diagnosed?

Blood and imaging tests done to help diagnose pulmonary hypertension may include:

  1. Blood tests. Blood tests can help determine the cause of pulmonary hypertension or detect signs of complications.
  2. Chest X-ray.
  3. Electrocardiogram (ECG).
  4. Echocardiogram.
  5. Right heart catheterization.

What is primary pulmonary arterial hypertension?

Primary pulmonary hypertension (PPH) is high blood pressure in the lungs. It’s a rare lung disorder in which the blood vessels in the lungs narrow and the pressure in the pulmonary artery rises far above normal levels.
